# What is Impossible Cloud Impossible Cloud offers next-generation, resilient object storage optimized for fast data backup and retrieval. ### Who can benefit from the product? Enterprises and SMBs backing up data to centralized, public cloud providers, or using on-premise solutions, who are looking to save up to 80% on data storage costs. Additionally, companies that prioritize: * Avoiding the downtime of centralized cloud providers * Improving the security of their backups * Increasing performance ### What are the product benefits? #### Availability and Resilience * Public cloud providers enabled many companies to lower the TCO of data backups - e.g., by rendering their data centers obsolete and reducing management complexity. Despite this advantage, public cloud providers have experienced numerous outages that affected thousands of companies and millions of customers. This effectively shows that traditional multi-zone redundancy architecture is unreliable. * Impossible Cloud stores data over a distributed architecture designed to eliminate single points of failure. This in turn creates superior reliability, resulting in optimized availability (lower downtime) and resiliency (faster recovery time). #### Security and Durability 1. Impossible Cloud's distributed architecture ensures superior file security and durability: * After receiving files from the customer, we encrypt each file with a respective unique key. We then store the files at enterprise-grade data centers - each with industry-relevant certificates incl. ISO 27001 and PCI DSS. Individual nodes within the data centers redundantly encrypt files at rest to further increase security. * We employ algorithms that continuously maintain the integrity and consistency of files in case any particular server or disk is unavailable. For instance, these algorithms enable reconstruction of files in case a copy on a specific device goes down for any reason. * Our storage is designed for at least 11 nines of durability (99.999999999%) - meaning our architecture minimizes the probability of file loss to near zero. 2. Besides security advantages, we combine established industry best practices with multi-layer encryption: * Identity and access management (IAM) * Default SSL HTTPS end-to-end encryption * Server-side encryption * Support of client-side encryption #### Throughput speed and latency Impossible Cloud Storage is based on innovative architecture and a plethora of underlying tools that help ensure the highest performance in terms of throughput speed as well as low latency: * Files are downloaded from multiple concurrent locations. This multi-threaded, peer-to-peer parallel structure maximizes bandwidth to enhance performance and throughput speed. * Data and metadata are both distributed, enabling users with the fewest required “hops”. This provides low-latency with better, if not the same, performance with the leading industry providers of hot storage. ### Why should you care? Backup to the public cloud adds an additional reliability dimension when storing the data. However, this often comes at the cost of security and throughput speed, as well as high costs and exorbitant retrieval (egress) fees. Impossible Cloud provides a storage architecture that measurably improves these critical challenges of the major centralized, public cloud providers. We offer a robust architecture, a new benchmark for security, and highly performant upload and retrieval. Customers using Impossible Cloud Storage will measurably and safely improve backup recovery time objective (RTO) and recovery point objective (RPO) metrics. Additionally, customers can leverage our transparent prices and save up to 80% compared to major public cloud providers. # Getting Started with Impossible Cloud Storage Welcome to the Impossible Cloud Storage family! This guide is designed to help you get up and running as smoothly as possible, whether you're a business or an individual user. ## What are 'Buckets' and 'Objects'? At the heart of our service are two simple concepts - Buckets and Objects. A **Bucket** is a container for your data. Think of it like a big digital box where you store all your files, which we refer to as **Objects**. An **Object** represents an individual file that you store in a Bucket. This can be any file you need to store – a photo, a document, a video, and more. Once an object is placed in a bucket, it's ready for you to interact with. You can open it, download it to your device, or update its properties. And when you're finished with an object or even an entire bucket, you can delete them to keep your resources tidy and organized. ## Key Protective Features: Object Lock and Versioning We've built in a couple of unique features to ensure the security and integrity of your data. **Object Lock** is a feature that protects your objects from being altered or deleted for a set period. It's like a digital safe for your most important files. It's also known as **WORM:** Write-Once-Read-Many**.** It is designed to provide an additional layer of data protection. It prevents the permanent deletion of objects during a period defined by you, serving as an enforceable retention policy. This comes in handy for regulatory compliance or when you need an extra safety net for your data. **Versioning** is another safety measure that lets you retrieve any deleted or overwritten items. It's like having a time machine for your data! The true strength of versioning-enabled buckets lies in their ability to help you recover objects from accidental deletion or overwriting. Let's say you delete an object; Impossible Cloud Storage will insert a 'delete marker' instead of permanently removing the object. This 'delete marker' then becomes the current version of the object. Similarly, if you overwrite an object, it results in a new object version in the bucket, but don't worry, you can always restore the previous version. For a deeper dive into **Versioning** and **Object Lock**, we invite you to explore our detailed guides: * Learn more about managing different versions of your objects with [Versioning](/impossible-cloud-help/impossible-cloud-storage-guide/buckets-and-objects/versioning-and-object-lock/enabling-versioning). * Discover how to add an extra layer of data protection with [Object Lock](/impossible-cloud-help/impossible-cloud-storage-guide/buckets-and-objects/versioning-and-object-lock/enabling-object-lock). # Setting up ## Sign-Up and Log in Before you can use Impossible Cloud Storage, you'll need to sign up and log in. 1.

You can group related files (objects) by giving them a shared beginning to their names, almost like they're in a folder. Just like you can have folders inside folders on a computer, you can do the same here, but you can't have buckets inside buckets. You can create these virtual folders and put objects directly into them, and while you can create and delete these folders, renaming and sharing them are not an option. ## Key Use Cases Here are a few examples you can use Impossible Cloud Storage: 1. **Backup and Recovery**: Securely back up your files and recover them whenever needed. 2. **Media Hosting and Management**: Store and distribute media files, like images and videos, directly from your bucket. 3. **Data Archiving**: For data that isn't accessed frequently but still needs to be retained, Impossible Cloud Storage provides a cost-effective solution. Historical data, long-term records, or old project files can be securely stored in the cloud and retrieved whenever needed. 4. **Big Data Analytics**: Many businesses are now using large-scale data analysis to drive decisions. Impossible Cloud Storage can be used to store large datasets, providing an accessible and scalable solution for your big data analytics needs. While the use cases we've outlined are common, Impossible Cloud Storage is versatile S3 compatible storage and can be tailored to many different needs. Your requirements dictate its use - so it's not just for backups, media hosting, and the other examples we mentioned. Explore and see what it can do for you. # Getting support ## Further Assistance and Information Need more help? Here are some useful links: 1.

After registration, you immediately get a 30-day free trial. Please find more information on the free trial [here](https://www.impossiblecloud.com/free-trial). # Signing in to Impossible Cloud Storage After receiving your account details as a root user or an IAM user, you can log in with your unique credentials to ICSC: * Navigate to our [login page](https://console.impossiblecloud.com/) and login with your credentials * Depending on your user type, select the correct login form.
* If you forgot your password or logging in for the first time, you can navigate to '**Forgot password**' and put in your email. You will then receive an email with instructions to reset your password.
{% hint style="info" %} Refer to our [relevant documentation](/impossible-cloud-help/impossible-cloud-storage-guide/profile-settings/change-password) on rules for setting a password. {% endhint %} {% hint style="warning" %} Forgot password only works for a user that already has console access set up (a login profile). If your account was created with API-only access (access key and secret key, no password), it has no login profile yet, so the reset request sends no email and shows no error. See [how to fix login profile not found](https://kb.impossiblecloud.com/en/how-to-fix-login-profile-not-found-when-resetting-a-storage-console-password) to add console access. {% endhint %} # Session lifetime limits Session lifetime limits determine how long the system should retain a login session. For security reasons, users are logged out automatically after certain intervals: * **Inactivity timeout**: Period after a user's session expires - given they do not interact with the console. This occurs after **3 minutes** **of inactivity**. * **Require login after**: Period after a user's session expires - independent of their interaction with the console. This is set to **30 days after login**. # Interacting with the console After signing in to the Impossible Cloud Console, you can see both the **menu** on the left-hand side as well as the **panel** on the right-hand side. See the following pages for details on how to both navigate the menu as well as use the panel.
# Navigating the menu You can **access the console's features** from the menu on the left-hand side of any page. Note that most of these are only visible for the root user - not the IAM users: * S3 Storage features: * **Buckets**: Manage your buckets and underlying objects ([see guide](/impossible-cloud-help/impossible-cloud-storage-guide/buckets-and-objects)). * **Usage**: See details of your plan and storage as well as egress consumption ([see guide](/impossible-cloud-help/impossible-cloud-storage-guide/billing)). * IAM features ([see guide](/impossible-cloud-help/security/identity-access-management-iam)): * **Keys**: Find all information for authentication on your S3 API ([see guide](/impossible-cloud-help/impossible-cloud-storage-guide/access-keys)). * **Users**: Add, delete or edit details of your IAM users ([see guide](/impossible-cloud-help/security/identity-access-management-iam/managing-users)). * **Groups**: Add, delete or edit details of your groups ([see guide](/impossible-cloud-help/security/identity-access-management-iam/managing-groups)). * **Policies**: Add, delete or edit details of group-specific policies ([see guide](/impossible-cloud-help/security/identity-access-management-iam/managing-policies)). * Additional features: * **Help Center**: Opens the [contact support](https://forms.clickup.com/24413607/f/q91d7-11767/AEQCWX2YUD4PX7RRLR?CanonicalID=documentation) link. You may expect to receive feedback per our SLA according to the ticket's priority. Please see our [Terms of Service](https://www.impossiblecloud.com/terms-of-service) document for more information. * **Profile Settings:** Modify the profile settings of your user. For example, you can enable Multi-Factor Authentication (MFA). * **Log out**: Sign out of your account to deactivate your session, sign in as a new user or reset your password. # Using the panel The panel opens on the right-hand side of the page when you select an item in the menu - for example, opening a bucket will show its objects and folders in the panel. It is the key area for **user interaction** and consists of a table listing your items, a search bar at the top, and pagination controls at the bottom. The information is set up to show **10 rows per page** by default, but you can change this to 20, 50, or 100 using the selector at the bottom right-hand side of the panel. You can also navigate to the different pages by clicking on a designated number or using the **<** and **>** buttons. When browsing objects inside a bucket, the bottom left shows a count of all objects and folders under the current prefix. While objects are still loading the count is shown as a lower bound (e.g. "Loading 500+ items..."); once loading is complete it shows the exact total. You can also **search for any sub-item** within the selected menu item. Simply use the search bar located at the upper part of the panel. The console will then show all related items that match the entered search string - e.g., buckets or folders within a bucket. {% hint style="info" %} The console lists a maximum of **10,000 objects per prefix**.\ For listing all objects in a large bucket, please use the [CLI](/impossible-cloud-help/impossible-cloud-storage-guide/cli-user-guide) or an [S3 browser](https://kb.impossiblecloud.com/en/how-to-connect-s3-browser-to-impossible-cloud-storage). {% endhint %} # Buckets and Objects Impossible Cloud stores files and folders, i.e., objects, in buckets. You can upload any objects after creating such a bucket. See the following how-to pages for details: * [**Create** ](/impossible-cloud-help/impossible-cloud-storage-guide/buckets-and-objects/creating-a-bucket)buckets * [**Store** ](/impossible-cloud-help/impossible-cloud-storage-guide/buckets-and-objects/storing-objects-in-a-bucket)objects in a bucket * [**Create** ](/impossible-cloud-help/impossible-cloud-storage-guide/buckets-and-objects/creating-folder)folders * [**Interact** ](/impossible-cloud-help/impossible-cloud-storage-guide/buckets-and-objects/actions-with-files-or-folders)with files and folders * [**Delete** ](/impossible-cloud-help/impossible-cloud-storage-guide/buckets-and-objects/deleting-folders-or-files-or-buckets)files, folders or buckets # Creating a bucket Creating a bucket allows you to **store any object - irrespective of type or size**. To create a bucket, simply navigate to the 'buckets' menu item and click on 'Add Bucket'. You are then asked to **edit its properties** - i.e., define its **name** and choose whether to use **versioning** (see [relevant documentation](/impossible-cloud-help/impossible-cloud-storage-guide/buckets-and-objects/versioning-and-object-lock/enabling-versioning)) and **object lock** (see [relevant documentation](/impossible-cloud-help/impossible-cloud-storage-guide/buckets-and-objects/versioning-and-object-lock/enabling-object-lock)). While the versioning property can be changed at a later point in time, both the name and object lock properties are unchangeable. You can select a specific geographical region for data storage in your bucket and once selected, the bucket's region cannot be changed. This option ensures that your data complies with local residency laws and improves performance by reducing latency. Please see the full list of all the available regions, their geographical locations and S3 API endpoint URLs [here](/impossible-cloud-help/impossible-cloud-storage-guide/storage-console-urls-and-api-endpoints). {% hint style="info" %} All regions comply with Impossible Cloud's geo-fencing policy, ensuring that your data stays within the selected region. A region in Impossible Cloud can include Datacenters in one or more countries, e.g. Germany, Benelux, etc. {% endhint %} Click 'Add' to finalize the process and a new bucket will be created. We recommend choosing a **bucket name** **that reflects the objects** you will store in that bucket as it is visible in the URL. For details on naming rules, see our [relevant documentation](broken://pages/KQX7z7UdpZwQNtD38r5b). {% hint style="warning" %} If you need to create a bucket in a specific region, you have to use the appropriate regional endpoint to make a request. For example if you need to create a new bucket in the **eu-west-1** region: \ \&#xNAN;*aws s3api create-bucket --profile impossiblecloud **--endpoint-url ** --bucket mytestbucket*\ \ If you were using another regional endpoint, then the bucket will be created in that endpoint. The parameters ***--region*** and ***--create-bucket-configuration LocationConstraint*** are ignored. {% endhint %} # Storing objects in a bucket Once you have created a bucket in the Impossible Cloud Storage console, you can access the bucket and store an object. There are two ways to upload an object: 1. You can use the **built-in drag & drop function**. 1. Open the relevant bucket in the console, drag the object from your device and drop it into the relevant area in the panel. This also works for multiple objects at a time.
2. You can use the **'Upload File' feature**. 1. Open the relevant bucket in the console, click on the 'Upload File' button and select the relevant objects for the upload.
# Interacting with objects There are two main interactions for objects - downloading and deleting. For more sophisticated interactions, see our relevant documentation for [versioning and object lock](/impossible-cloud-help/impossible-cloud-storage-guide/buckets-and-objects/versioning-and-object-lock) as well as [IAM](/impossible-cloud-help/security/identity-access-management-iam): * **Download:** Navigate to the particular bucket and click on the object or use the download button ![](/files/12l10y1f1LQTZ77dy9yV) next to the specific object to download it. Afterward, the object will be downloaded to the default location on your device. * **Delete:** Navigate to the particular bucket and click on the delete button ![](/files/1CRH3PyuFNCDytVjC0aU) next to the specific object to delete it. Alternatively, you can remove multiple objects by marking an object(s) and click 'Remove *x* object' on the upper right-hand side of the panel. Note that the delete action is irreversible unless versioning is enabled. # Creating folders in a bucket Impossible Cloud Storage generally stores objects in a flat structure. However, you may create a **virtual structure** yourself by simulating a directory. For this purpose, you can use our 'create a folder' feature. Simply navigate to 'buckets' and the particular bucket or sub-folder within a bucket. Afterward, click on 'Create Folder' and define a name. Note that you cannot upload a folder to our console and only create it inside the bucket.
{% hint style="info" %} In contrast to naming a bucket, you may name your folder as it is most meaningful for you. Only the names '.' and '..' are not allowed. {% endhint %} # Interacting with folders and buckets You may remove one or more folders after they were created. Simply navigate to the particular bucket, select the folder, and click on 'Remove object' or click on the delete button ![](/files/5uo8UG8GXABAFiU8cdX8) next to the specific folder.

Deleting a folder in a bucket

This action also applies when deleting buckets. Note that the delete action is irreversible.

Deleting a bucket

# Public File Sharing via URLs This guide guides you through creating public links for your files stored on Impossible Cloud, allowing you to share them with anyone, even if they don't have an Impossible Cloud account. A public link, or a pre-signed URL, is a secure way to provide access to a specific file in your bucket for a limited time. You generate this link directly from the Impossible Cloud interface, and it can be used by anyone to download the file until the link expires. This is an effective way to distribute files without altering your bucket's overall privacy settings or sharing your access credentials. ### Prerequisites * You have logged in to your Impossible Cloud account. * You have files uploaded to your bucket that you wish to share. ### Step-by-Step Guide 1. **Navigate to Your Bucket** * Access the 'Buckets' section on your Impossible Cloud dashboard. * Select the desired bucket that contains the file you want to share. 2. **Locate the File to Share** * Scroll or search for the file in your bucket's object list. * Once you have located the file, you’ll notice a 'share' icon to the right of the file name. 3. **Initiate the Sharing Process** * Click on the 'share' icon. * A dialog titled 'Share object with a pre-signed URL' will appear, displaying the name of the object you are sharing. 4. **Set the Expiration Interval** * In the dialog, you will see an option to set the 'Expiration interval'. * You can specify how long the pre-signed URL will be valid, choosing between 1 minute and 12 hours. The time can be set in minute or hour increments. 5. **Generate the Pre-Signed URL** * After setting the expiration time, click the 'Share' button. * A notification will confirm that a pre-signed URL has been generated and copied to your clipboard. 6. **Save and Distribute the Pre-Signed URL** * Since the link can only be generated once, immediately paste and save it in a secure location. * Share the pre-signed URL with your intended recipients. They will be able to access the file until the expiration time is reached. # Emptying a Bucket The 'Empty Bucket' feature provides a straightforward way for root users to delete all objects within a selected bucket via the Impossible Cloud interface. This tool is especially valuable when you need to ensure a bucket is completely cleared of its contents, which can be challenging to accomplish manually if dealing with large quantities of data, various object versions, or protected items. It simplifies what would otherwise require scripting expertise and command-line operations. {% hint style="warning" %} Note that this feature will only delete the contents of the bucket. The bucket itself will remain intact. If you wish to delete the bucket entirely, this must be done as a separate action after emptying the contents. {% endhint %} ### Prerequisites * You must have root access to the Impossible Cloud account. * Ensure the bucket you choose is the one you intend to empty. ### **Step-by-Step Guide** 1. **Access Bucket Settings** * Navigate to the 'Buckets' tab on your Impossible Cloud dashboard. * Click the cogwheel icon beside the bucket you wish to empty to open its settings. 2. **Schedule the Emptying Process** * Find and activate the 'Emptying the bucket' setting, noted as not scheduled by default. 3. **Confirm the Deletion Process** * Read the pop-up details regarding the permanence of the action and exceptions for Object Lock. * Type "permanently delete" to confirm and activate the 'Permanently Delete' button. 4. **Finalize the Schedule** * Click on the ‘Permanently Delete’ button to confirm the deletion. This action will initiate the bucket emptying process, which will begin in 24 hours from the time of confirmation. This 24-hour delay is fixed and cannot be altered by the user. * The settings page will then display the scheduled time for the process. 5. **Monitor Status or Cancel** * On the bucket's page, a notification will inform you of the scheduled emptying. * As a root user, you can cancel the process before it commences if necessary. 6. **Check Completion** * After the scheduled time, the bucket's page will indicate the completion of the emptying process. * Verify that the bucket is empty before using it again. # Limitations ## Number of buckets limitations You can keep any quantity of items in a single bucket, and your account can have a maximum of 100 buckets. ## Restrictions on Operating System/Filesystem level Object names are primarily limited by the local operating system and filesystem. Some operating systems such as Windows restrict certain characters in file names, such as: `; ^ / * | " &` Please note that this list may not be exhaustive and the restrictions may vary based on the operating system and filesystem in use. Consult the documentation of your operating system vendor or filesystem for a comprehensive list of restrictions for your specific situation. Impossible Cloud Storage currently does not support the following object names: 1. Forward slashes at the beginning. 2. Empty path segments. ## S3 API limitations | Max size of any object | 50 TiB | | ------------------------------------------------ | ------ | | Min size of any object | 0 B | | Max length for bucket names | 63 | | Max length for object names | 1024 | | Max length for `/` separated object name segment | 255 | ## Object conflicts Objects must have names that are unique and do not conflict with their parent objects. To prevent naming conflicts, applications must assign keys to objects that are unique and non-conflicting. For instance, the second PUT operation in the following sequence will fail because of a naming conflict with the object created by the first operation: ``` PUT /xxx/yyy/textfile.txt PUT /xxx/yyy ``` ``` PUT /xxx/yyy PUT /xxx/yyy/textfile.txt ``` To avoid issues, please ensure that object names are always unique and do not conflict with their parent objects. # Versioning and object lock As an enterprise-grade cloud service provider, we offer **sophisticated versioning and object lock** features in our Impossible Cloud Storage product. These features are designed to provide our users with **advanced data protection and management capabilities**. Our product is built following the industry standard, Amazon S3, so users can expect the underlying features to be similar to what they're accustomed to from other cloud providers. * **Versioning:** Our versioning feature allows you to **save, retrieve, and restore any version** of an object saved in a bucket. Versioning provides an **extra layer of security** by offering a way to restore deleted or overwritten items. This makes it simple to recover from user or application errors. Versioning is also helpful for data archiving and preservation. * **Object lock:** Our object lock feature is a **data protection function** that allows users to select particular objects to be **immutable**. This means that the objects cannot be altered or deleted by any user. Users can also set a period for an object to remain immutable, after which it can be modified or deleted. It's important to note that object lock requires versioning Object lock differs from versioning in that object lock **prevents users from permanently deleting** each version of the object - while versioning simply allows users to create and delete versions of an object. Thus, with object lock you can store objects using a **write-once-read-many (WORM)** model. There are three different types of retention modes: * **Compliance**: A protected object version can neither be overwritten nor deleted **by any user**. Additionally, its retention mode cannot be changed, and its retention period cannot be shortened. This enables the highest data protection functionality. * **Governance**: A protected object can neither be overwritten nor deleted. Additionally, its lock settings cannot be altered **unless the user has been assigned the necessary permissions**. Therefore, you can still grant some users permission to modify the retention settings or delete the object if required. You can also use governance mode to test retention-period settings before creating a compliance mode retention period. * **Legal hold**: This operation prevents an object version from being overwritten or deleted even if the **retention period expires**. Only designated users can overrule this hold. Object lock can, for instance, help you meet regulatory requirements that require WORM storage or protect you from ransomware cases - as objects remain unchanged on our platform.

Thus, when Impossible Cloud receives multiple write requests for the same object simultaneously, it stores all of those objects as versions. This feature has to be enabled on a bucket level - when creating the folder or by editing its settings: * To activate versioning when **creating a bucket**, simply create a new bucket and enable its versioning.

Enabling versioning when creating a bucket.

* For enabling or disabling versioning later in the process, navigate to the bucket overview and **change the respective bucket's settings**.

Enabling/disabling versioning on an existing bucket from bucket settings

# Using versioning When interacting with objects in a versioning-enabled bucket, you have several options: * Add **different versions**: In a non-versioning bucket, uploading the same object multiple times overwrites the previous object. In versioning, every version is kept - as long as the file name incl. the name extension is precisely like the one previously uploaded. * Add **delete markers** and **reverse the action**: You can add a delete marker to any object - which subsequently hides the respective object. In other words, the object and its previous versions no longer appear as items in the bucket. This action can be reversed - by restoring all previous versions of the object. * **Download specific versions**: You can either download the latest version of an object or any particular version that was uploaded previously. This can even be done when a delete marker is placed on an object. * Permanently **delete specific versions**: When you have uploaded multiple versions, you can delete particular versions. This will remove them from our platform - making a recovery of the deleted version impossible. To add **different versions**, simply re-upload an object that you have already uploaded previously. The name must precisely be the same as before - incl. the object's extension.

All versions of an object are visible in versioning-enabled buckets.

New uploads result in a new version that is highlighet with 'latest'.

Versions can only be created when the name precisely matches - incl. the object's extension.

To add a **delete marker** and hide an object, click on the delete button next to the object. Note that the delete button next to each version behaves differently and triggers object version operations rather than object operations. It's essential to ensure that 'Delete all versions' is disabled. To **reverse** this action, simply choose to show deleted files and restore the object.

Click the button next to the respective object.

Make sure that 'Delete all versions' is disabled and then click 'delete latest version'.

Enable 'Show deleted files', click on the respective button next to the marker and click on 'Restore' to restore the object.

To **download specific versions**, you can either download the object - which in turn downloads the latest version - or you can choose a particular version. This latter feature also works when a delete marker is placed on the object.

You can download any version of an object.

Checkmark 'Show deleted files' to show buckets with a delete marker - you can then download any version.

To **permanently delete objects**, you can either delete a specific version or delete the entire object. Note that these actions are irreversible.

Click on the delete button next to the respective version to delete the specific version.

Click on the delete button next to the respective object and enable 'Delete all version' to delete the object incl. its versions.

# Enabling object lock Object lock can prevent objects from being removed or overwritten for a specified period. Note that you must first enable versioning before enabling this feature on a bucket. Unlike versioning, object lock must be enabled at the time of bucket creation and the settings cannot be changed after creation. You can either choose to define a retention period for each object individually or for all underlying objects. Legal holds can only be defined by version or object and not by bucket. * **Reserve the option for individual retention periods** for underlying objects by leaving the 'Retention' checkmark blank.
* **Set up aggregate retention periods** for all underlying objects by defining the retention mode and validity when creating the bucket.
# Using object lock ## Overview After you create a bucket with object lock enabled, you can manage retention and legal hold settings at the bucket and object level. The retention mode (Compliance or Governance) is set during bucket creation and cannot be changed in the Storage Console afterward. You can extend retention periods, but not shorten them. All operations below require the appropriate IAM permissions. ### Retention modes When you set a retention policy on a bucket or object, you choose one of two modes: | Mode | Who can delete or shorten retention | Use case | | -------------- | ----------------------------------------------------------------------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------ | | **Compliance** | No one. Not even the root user. The object version is immutable until the retention period expires. | Regulatory requirements (SEC, FINRA, HIPAA) that mandate true WORM storage. | | **Governance** | The root user, or any IAM user with the `s3:BypassGovernanceRetention` permission, can delete the object or shorten the retention period. | Testing retention settings before applying Compliance mode, or protecting data while keeping an administrative override. | You can set a default retention mode and period (in days or years) for a bucket only during bucket creation. After creation, the **Retention** section in bucket settings shows the current configuration but the mode selector will be disabled. #### What you can do in the Storage Console * **Enable retention at creation time.** When creating a bucket with object lock, select either **Compliance** or **Governance** mode and enter the validity period in days or years. This default applies to all objects uploaded to the bucket. * **Extend the retention period.** If the bucket already has retention enabled, you can increase the validity (for example, from 30 days to 90 days). The console accepts the new value. * **You cannot decrease the retention period.** The console will show the error "You cannot decrease object lock time" if you enter a shorter value. This restriction also applies via the API. * **You cannot switch from Compliance to Governance.** The console shows "Switching back from Compliance mode is not allowed." This restriction also applies via the API. ### Change object or version retention You can view and modify retention settings for individual objects or specific versions. In the bucket view, click the **Settings** (gear) icon next to an object to open **Object settings**. Expand the object row to see all versions with their Version IDs and access settings per version. The **Object settings** dialog shows two sections: * **Retention Policy** with the current mode (Compliance or Governance) and the **Date** field showing when retention expires. You can switch from Governance mode to Compliance, but not vice versa. You can as well prolong the existing retention here. * **Legal Hold** with a toggle to turn it on or off. ### Delete markers and locked objects Object lock does not prevent adding a **delete marker**. A delete marker hides the object from the default listing but does not remove any version. You can view a hidden object by enabling **Show deleted files** in the bucket view. You cannot permanently delete a version that has an active retention period or legal hold. The console shows an error if you try. This applies regardless of whether you use the console or the CLI. To permanently delete a Governance-locked version before its retention expires, use the AWS CLI with the `--bypass-governance-retention` flag. Compliance-locked versions cannot be permanently deleted until the retention period expires. {% hint style="info" %} The scheduled bucket emptying feature in bucket settings also cannot remove objects protected by Compliance mode. Those objects remain in the bucket. {% endhint %} ### Legal hold A legal hold prevents an object version from being overwritten or deleted, regardless of its retention settings. Unlike retention modes, a legal hold has no expiration date. It stays active until you explicitly remove it. You can apply a legal hold to any object version, even if that version already has a retention period. Both protections operate independently: removing the legal hold does not affect the retention period, and the retention period expiring does not remove the legal hold. Key differences from retention modes: * **No expiration.** A legal hold persists until a user with the `s3:PutObjectLegalHold` permission removes it. * **Per-version.** You apply a legal hold to a specific object version, not to the entire bucket. * **Independent of retention.** An object can have both a retention period and a legal hold at the same time. The object remains protected as long as either one is active. To apply or remove a legal hold in the Storage Console, open the properties of the object version and toggle the **Legal Hold** setting. ### AWS CLI examples The following examples use the `eu-central-2` region. Replace bucket names, keys, and version IDs with your own values. #### Set Governance retention on an object ```bash aws s3api put-object-retention \ --bucket my-bucket \ --key my-object.txt \ --retention '{"Mode":"GOVERNANCE","RetainUntilDate":"2026-12-31T00:00:00Z"}' \ --endpoint-url https://eu-central-2.storage.impossibleapi.net \ --region eu-central-2 ``` #### Set Compliance retention on an object ```bash aws s3api put-object-retention \ --bucket my-bucket \ --key my-object.txt \ --retention '{"Mode":"COMPLIANCE","RetainUntilDate":"2026-03-30T00:00:00Z"}' \ --endpoint-url https://eu-central-2.storage.impossibleapi.net \ --region eu-central-2 ``` #### Bypass Governance retention to delete an object version The calling credentials must have the `s3:BypassGovernanceRetention` permission. ```bash aws s3api delete-object \ --bucket my-bucket \ --key my-object.txt \ --version-id "YOUR_VERSION_ID" \ --bypass-governance-retention \ --endpoint-url https://eu-central-2.storage.impossibleapi.net \ --region eu-central-2 ``` #### Apply a legal hold ```bash aws s3api put-object-legal-hold \ --bucket my-bucket \ --key my-object.txt \ --legal-hold '{"Status":"ON"}' \ --endpoint-url https://eu-central-2.storage.impossibleapi.net \ --region eu-central-2 ``` #### Remove a legal hold ```bash aws s3api put-object-legal-hold \ --bucket my-bucket \ --key my-object.txt \ --legal-hold '{"Status":"OFF"}' \ --endpoint-url https://eu-central-2.storage.impossibleapi.net \ --region eu-central-2 ``` #### Check retention and legal hold status of an object ```bash aws s3api get-object-retention \ --bucket my-bucket \ --key my-object.txt \ --endpoint-url https://eu-central-2.storage.impossibleapi.net \ --region eu-central-2 ``` ```bash aws s3api get-object-legal-hold \ --bucket my-bucket \ --key my-object.txt \ --endpoint-url https://eu-central-2.storage.impossibleapi.net \ --region eu-central-2 ``` ### Quick reference: Compliance vs Governance vs Legal Hold

# Access keys Access keys combined with an S3-compatible endpoint are used with third-party applications. They are used to **make programmatic calls to AWS S3 API actions**. There are two types of access keys: * **Access key ID** * **Secret access key** Access and secret keys are generated under the **"IAM → keys"** tab in the console menu bar. To create a new access key, simply navigate to the menu and click **"Add key"** on the top. When creating a new key pair, you may use the respective button to copy or download it. {% hint style="warning" %} Please copy and save the secret key somewhere once it's created. The secret key is only shown once! After you leave the window, the secret key is hidden and you will need to create a new key pair to obtain a complete set of keys. {% endhint %} {% hint style="info" %} For your protection, you should **never share your secret keys** with anyone. {% endhint %} # CLI User Guide Impossible Cloud Storage works seamlessly with the AWS S3 API. This means that you can use it with the AWS CLI or any other software that is compatible with AWS S3. If you want to use the AWS CLI with Impossible Cloud Storage, simply follow the guidelines on the next pages. {% hint style="info" %} See information about endpoints URLs [here](/impossible-cloud-help/impossible-cloud-storage-guide/storage-console-urls-and-api-endpoints). {% endhint %} # AWS CLI installation instructions Please install and use the AWS CLI version 2 {% hint style="info" %} For more information on the AWS CLI installation, go to {% endhint %} ## Linux {% tabs %} {% tab title="Linux" %} 1. Download the installation file ``` curl "https://awscli.amazonaws.com/awscli-exe-linux-x86_64.zip" -o "awscliv2.zip" ``` 2. Unzip the installer ``` unzip awscliv2.zip ``` 3. Run the install program ``` sudo ./aws/install ``` {% endtab %} {% tab title="Windows" %} 1. Download and run the AWS CLI MSI installer for Windows (64-bit): Alternatively, you can run the **`msiexec`** command to run the MSI installer. ``` c:\ msiexec.exe /i https://awscli.amazonaws.com/AWSCLIV2.msi ``` 2. To confirm the installation, open the Start menu, search for cmd to open a command prompt window, and at the command prompt use the **aws --version** command. ``` c:\ aws --version aws-cli/2.7.24 Python/3.8.8 Windows/10 exe/AMD64 prompt/off ``` {% endtab %} {% tab title="MacOS" %} 1. Download the file using the `curl` command. The `-o` option specifies the file name that the downloaded package is written to. In this example, the file is written to `AWSCLIV2.pkg` in the current folder. 
curl "https://awscli.amazonaws.com/AWSCLIV2.pkg" -o "AWSCLIV2.pkg"
2. Run the standard macOS `installer` program, specifying the downloaded `.pkg` file as the source. Use the `-pkg` parameter to specify the name of the package to install and the `-target /` parameter for which drive to install the package to. The files are installed to `/usr/local/aws-cli`, and a symlink is automatically created in `/usr/local/bin`. You must include `sudo` on the command to grant write permissions to those folders. ``` sudo installer -pkg ./AWSCLIV2.pkg -target / ``` After installation is complete, debug logs are written to **/var/log/install.log**. 3. To verify that the shell can find and run the `aws` command in your `$PATH`, use the following commands: ``` $ which aws /usr/local/bin/aws ``` ```markup $ aws --version aws-cli/2.9.23 Python/3.9.11 Linux/5.15.0-1030-aws exe/x86_64.ubuntu.22 prompt/o ``` {% endtab %} {% endtabs %} # AWS CLI configuration To use your Impossible Cloud Storage with the AWS CLI, you need to use the "**configure**" command. Simply type: ``` aws configure ``` You will be prompted to enter your access key and secret access key for Impossible Cloud Storage. When it asks for the region, you can either type "eu**-central-2**" or leave it blank. {% hint style="info" %} More information on Access Keys is [here](/impossible-cloud-help/impossible-cloud-storage-guide/access-keys). {% endhint %} If you need to configure a profile for a specific type of access, you can do so by typing: ``` aws configure --profile impossiblecloud ``` Then enter your Access Key ID and Secret Access Key, and you are ready to go. # Using Impossible Cloud with AWS CLI There are two ways to use Impossible Cloud with the AWS CLI. ## Method 1 The first method involves adding the following subcommand after every command: **--endpoint-url=**[**https://eu-central-2.storage.impossibleapi.net**](https://eu-central-2.storage.impossibleapi.net) For example, if you want to list your buckets in the CLI, please type: ``` aws s3 ls --endpoint-url=https://eu-central-2.storage.impossibleapi.net ``` or use a specific profile: ``` aws s3 ls --profile=impossiblecloud --endpoint-url=https://eu-central-2.storage.impossibleapi.net ``` ## Method 2 To make it easier to access third-party S3 providers, you can use the [awscli-plugin-endpoint](https://pypi.org/project/awscli-plugin-endpoint/) plugin, but you will need to create an additional profile along with the default one. To create this profile, you can add a "profile" line at the end of the config file located in the ".aws" directory in your home directory. Add a line profile line at the end of the config file like this at the end of the file: ``` [profile impossiblecloud] ``` After you've added the "profile" line to the config file, be sure to save the file. Once you have created a profile, you can follow the instructions provided on the plugin's GitHub page, which you can find at this link: . By doing so, you should be able to use "**--profile impossiblecloud**" after every command instead of having to type out the entire URL. For instance, if you wish to list your buckets using the AWS CLI, simply type: ``` aws s3 ls --profile=impossiblecloud ``` {% hint style="warning" %} If you need to create a bucket in a specific region, you have to use the appropriate [regional endpoint](/impossible-cloud-help/impossible-cloud-storage-guide/storage-console-urls-and-api-endpoints) to make a request. For example if you need to create a new bucket in the **eu-west-1** region: \ \&#xNAN;*aws s3api create-bucket --profile impossiblecloud **--endpoint-url ** --bucket mytestbucket*\ \ \&#xNAN;*If you were using another regional endpoint, then the bucket will be created in that endpoint.

In this page you can view your current usage, storage capacity, and an overview of how much storage you have left. The **Usage** section is only visible if you are accessing the Impossible Cloud Storage Console using a root user account. If you are using Impossible Cloud Storage with a pay-per-use plan, the remaining storage amount will not be displayed, as charges are based entirely on your current usage. For more information, see the following pages for details. # Storage Calculation At Impossible Cloud Storage, we follow a decimal storage calculation where 1 terabyte (TB) is considered 1,000 gigabytes (GB), and 1 gigabyte is considered 1,000 megabytes (MB). This means that when you see our storage pricing of €7.99 per terabyte for the 'Pay-per-use' plan, it is equivalent to €0.00799 per gigabyte. We adopt this calculation method to provide a consistent and transparent pricing structure for our users. Using a base of 1,000 rather than 1,024 simplifies the storage calculation process and allows for easier budgeting and cost management. When estimating your storage requirements and understanding the associated costs, keep in mind that each gigabyte is comprised of 1,000 megabytes and each terabyte is comprised of 1,000 gigabytes. This ensures clarity and accuracy when calculating your storage expenses with Impossible Cloud Storage. If you have any further questions or need assistance with understanding your billing and storage calculations, please don't hesitate to reach out to our support team. We are here to help you make the most of your storage resources efficiently and cost-effectively. # Fair use policy Impossible Cloud's fair use policy ensures equitable access to cloud storage services for all customers. It is designed to prevent individual accounts from monopolizing shared infrastructure - particularly through excessive data egress - in ways that could degrade service quality for others. The policy is based on a simple threshold: **your monthly egress should not exceed your active storage volume.** For example, if you store 100 TB with Impossible Cloud and download up to 100 TB within a monthly billing cycle, this is considered reasonable use. Activities that generate an excessive number of requests or data transfers that disrupt service for other users are explicitly prohibited. If your workload regularly requires egress volumes that exceed your stored data - such as media delivery or AI training workloads - please reach out to our commercial team to align on a custom arrangement. For full details, see our Knowledge Base article: [What is Impossible Cloud's Fair Egress Policy?](https://kb.impossiblecloud.com/en/what-is-impossible-cloud-fair-egress-policy) # Profile settings Your Account Settings: An Overview Here, the **Profile Settings** page is a control hub for your Impossible Cloud Storage account. To start managing your profile settings, simply go to the **Profile Settings** menu or go to the "ellipsis" (three dots) at the top-right corner of your screen next to your user details, and select **Profile Settings**. # Multi-Factor Authentication (MFA) The Impossible Cloud Storage Console supports Multi-Factor Authentication (MFA) using various third-party authenticator applications. Learn more about how MFA works in this section. # Enabling and Disabling MFA By default, your Impossible Cloud Storage account does not have Multi-Factor Authentication (MFA) enabled. However, turning on MFA is a snap and it significantly boosts the security of your account. Impossible Cloud Storage Console provides the ability to enable MFA for you and your organization. ## To enable MFA: 1. Navigate to the **Profile Settings** page. 2. Click the **Multi-Factor Authentication** switcher button to enable MFA. You will notice the switcher turn green, indicating that MFA is now active. Once you have enabled MFA, you will be asked to set it up at your next login. You will need an authenticator application to generate a unique code to login to Impossible Cloud Storage Console. The Impossible Cloud Storage Console's Multi-Factor Authentication supports various third-party authenticator applications, such as Google Authenticator, Microsoft Authenticator, or others. Once you set up the MFA authentication, Impossible Cloud Storage Console will ask for the unique code that is generated on your chosen authenticator application at every log in. As a root user in Impossible Cloud Storage Console, you have the option to enable/disable MFA for sub-users linked to your account. Additionally, root users can also enforce MFA policy to the whole organization to protect all access to Impossible Cloud Storage Console. Learn more about this on [Organization-Wide Policies](/impossible-cloud-help/impossible-cloud-storage-guide/profile-settings/multi-factor-authentication-mfa/organization-wide-policies) section. {% hint style="info" %} If you enable the "Enforce MFA policy to all users in your organization" checkbox and confirm the change, the MFA becomes mandatory for all sub-users, making it impossible for any sub-user to disable MFA. {% endhint %} ## To disable MFA: 1. Go to the **Profile Settings** page. 2. Click the **Multi-Factor Authentication** switcher button to disable MFA. The switcher will turn grey, indicating that MFA is now inactive. Please note, disabling MFA will revert your login process to using only your username and password. # MFA Reset If you lose access to your authenticator device or need to reset your Multi-Factor Authentication (MFA), you can reset your MFA settings by following the steps in this section. {% hint style="info" %} Please note that this process is only possible while you are logged into your Impossible Cloud Storage account and your session is active: {% endhint %} The steps are as follows: 1. Navigate to the **Profile Settings** page. 2. In the MFA section, click on the **Reset MFA for this account** button. 3. A message will appear confirming the successful reset of your MFA. This reset process allows you to link a new device with your MFA-enabled account, should your previous device be lost or malfunction. It's important to note that active sessions expire after 30 days of inactivity. If you are unable to log in and reset your MFA due to an expired session, you will need to [contact our support team](https://hs.impossiblecloud.com/en/customer-support) for assistance. Once the MFA reset process is completed, you will be prompted to set up MFA again at your next login with a new device using an authenticator application. #### MFA Reset for Individual Sub-Users by Root User For root users who need to reset Multi-Factor Authentication (MFA) settings for other sub-users within their organization, MFA reset button is available under the [Organization-wide Policies](/impossible-cloud-help/impossible-cloud-storage-guide/profile-settings/multi-factor-authentication-mfa/organization-wide-policies) section for each sub-user. # Organization-Wide Policies A root user has a few more MFA options under the **Organization-wide policies**. You will see a list of sub-users linked to your main account and you will be able to manage their MFA settings. One important feature is the **Enforce MFA policy to all users in your organization** checkbox. If you enable this checkbox and confirm the change, the MFA becomes mandatory for all users, including you. Essentially, it locks in the MFA policy across your organization, making it impossible for any sub-user to disable MFA. As for individual sub-users, while they cannot disable MFA once the organization-wide policy is in effect, they can still reset their own MFA. Please note that this process is only possible while you are logged into your Impossible Cloud Storage account and your session is active. There is also a **Reset MFA** button for each sub-user in the **Organization-Wide Policies** list. **Organization-Wide Policies** are exclusively available for root users. Sub-users do not have access to these functions. # Change Password The Impossible Cloud Storage Console allows users to change their password. To change password, you must enter their current password and enter the new password. The password must follow the password requirements: * Password must be at least 8 characters * Password should include lower-case (a-z), upper-case (A-Z) and number (0-9) characters * Password must contain at least one special character * The new password and its confirmation must be identical You will receive the following error message if one or more of the requirements are not met: > *Either the new password does not conform to the account password policy or the old password was incorrect.* # Securing Your Data A Comprehensive Guide to Security in Impossible Cloud Storage ## Overview Security is a paramount concern when it comes to cloud storage solutions, and Impossible Cloud Storage is committed to providing robust security measures to protect your valuable data. In this guide, we will delve into the various aspects of security offered by Impossible Cloud Storage, ensuring a comprehensive understanding of the measures in place to safeguard your information. ## Operational security ### [MFA support](/impossible-cloud-help/impossible-cloud-storage-guide/profile-settings/multi-factor-authentication-mfa) Ensuring the security of your user accounts is essential, and Impossible Cloud Storage offers support for Multi-Factor Authentication (MFA) to add an extra layer of protection. While enabling MFA is available for the root account, subusers can also leverage this feature for enhanced security. Furthermore, root users can mandate MFA for their subusers, enhancing the overall security of the accounts. ### Containerisation Containerisation provides an added layer of security for clients' data in Impossible Cloud Storage. By running the application in isolated containers, the risk of data exposure or compromise is significantly reduced. Each application container is independent and isolated from others, as well as from the underlying host operating system, ensuring that even if the security of one container is compromised, the integrity and confidentiality of other containers and data remain intact. ### Authenticating requests Impossible Cloud supports both Amazon S3 Signature Version 2 and Version 4 for API requests. For better security, we recommend using Signature Version 4, as it uses a signing key instead of your secret access key. Please avoid using Version 2 if possible. ## Compliance and Certifications Impossible Cloud Storage takes data safety seriously, and as part of our commitment to maintaining high standards, our datacenters hold certifications such as [ISO 27001 ](https://www.iso.org/standard/27001)and [PCI DSS](https://www.pcisecuritystandards.org/standards/pci-dss/). These certifications validate our adherence to stringent security protocols, assuring users of the safety and protection of their data. ## Client-Side Encryption To ensure end-to-end encryption and give users full control over their data, Impossible Cloud Storage fully supports client-side encryption. This means that you can encrypt your data on the client side using your preferred encryption algorithms or tools, and Impossible Cloud Storage seamlessly integrates with the encrypted data without interference. ## In-Transit Encryption As part of our commitment to data security, Impossible Cloud Storage exclusively supports HTTPS/TLS encryption for data transmission. This ensures that data moving between your devices and our storage infrastructure remains encrypted and protected, mitigating the risk of unauthorised access or data interception. Supported versions of TLS are 1.2 and higher. As part of this commitment, HTTP, the unencrypted counterpart, is not supported. By enforcing HTTPS/TLS encryption, all data exchanged between your devices and the storage infrastructure is encrypted, significantly reducing the risk of unauthorised access or interception of sensitive information. ## Server-Side Encryption Server-side encryption in Impossible Cloud refers to the automatic encryption of your data before it is stored and the decryption of your data when it is accessed. This process is conducted on the individual objects within your bucket. If you have enabled SSE-S3 (Server-Side Encryption with Amazon S3-Managed Keys) on a bucket, this encryption becomes the default setting for all objects in the bucket. This means that any data placed in the bucket is automatically encrypted. Even if you have not enabled SSE-S3 on a bucket, it's still possible to apply encryption to individual objects during the 'put-object' or 'copy-object' operations. This can be done using the AWS Command Line Interface (CLI). Regardless of whether your data is encrypted or unencrypted, accessing your data remains consistent. As long as you have authenticated your request and possess the necessary permissions, you can retrieve your data seamlessly. For instance, if you share your data via a presigned URL, it will function the same way for both encrypted and unencrypted objects. Additionally, when you request a list of objects in your bucket, all objects will be returned, regardless of their encryption status. **Please note that:** Currently, Impossible Cloud only supports 'SSE-S3' for server-side encryption. Other encryption methods, such as SSE-KMS (Server-Side Encryption with AWS Key Management Service) and SSE-C (Server-Side Encryption with Customer-Provided Keys), are not supported. ## At-Rest Encryption At Impossible Cloud Storage, we prioritise the security of your data at rest. To achieve this, we implement keys managed by Impossible Cloud which are used for server-side encryption, protecting your data while it is stored in our infrastructure. ## Object Lock (WORM) In line with industry standards and compatibility with AWS S3, Impossible Cloud Storage [supports](/impossible-cloud-help/impossible-cloud-storage-guide/buckets-and-objects/versioning-and-object-lock/enabling-object-lock) Object Lock functionality. Object Lock enables you to enforce retention periods, ensuring data immutability and compliance with regulatory requirements. Whether you need to preserve data for regulatory compliance, legal holds, data preservation, ransomware protection, disaster recovery, immutable backups, or auditing purposes, Object Lock provides the necessary governance and compliance features to meet your needs. ## Data Resilience ### Bit-Rot Protection Impossible Cloud Storage is designed to provide robust data resilience. At the time of upload (PUT) to the primary storage, data integrity measures are in place to ensure that your data remains intact and protected. The signature algorithm is SHA256 with RSA. Additionally, our infrastructure incorporates bit-rot protection, safeguarding against data corruption or loss due to hardware failures. ### Protection from Disk Failure To mitigate the risks associated with disk failure, Impossible Cloud Storage leverages advanced data protection techniques. Our backend employs erasure coding, a data redundancy method that distributes data across multiple drives, ensuring data integrity and resiliency in the event of a disk failure. ## Ongoing Security Monitoring and Updates Security is an ongoing process, and Impossible Cloud Storage continuously monitors and updates its security measures to stay ahead of emerging threats. Through regular security assessments, vulnerability scanning, and proactive monitoring, we strive to ensure the integrity, confidentiality, and availability of your data. ## Conclusion Security is of utmost importance when it comes to cloud storage, and Impossible Cloud Storage takes comprehensive measures to safeguard your data. By implementing features such as MFA support, client-side encryption, in-transit and at-rest encryption, object lock functionality, data resilience, and protection against disk and data center failures, we prioritize the confidentiality, integrity, and availability of your data. With our commitment to compliance, ongoing security updates, and robust network security measures, you can trust Impossible Cloud Storage to provide a secure and reliable storage solution for your valuable data. # Identity Access Management (IAM) ## Overview The Impossible Cloud Storage Console (ICSC) is an enterprise-grade cloud storage management tool that offers Identity and Access Management (IAM). This feature enables Role-Based Access Management (RBAC) for securing your storage and complying to data governance rules and regulatory requirements. The Impossible Cloud Storage is S3 compatible and is built based on the industry-standard. Thus, users can expect the underlying IAM features to be similar to what they are accustomed to. The Impossible Cloud Storage's IAM features can be configured through the Storage Console (GUI) as well as using the [AWS IAM API](/impossible-cloud-help/impossible-cloud-storage-guide/cli-user-guide/aws-cli-iam). ## Users, Policies, and Groups There are three main concepts that should be considered when using Impossible Cloud Storage's IAM features: **Users, Policies, and Groups** - each with a dedicated tab in the GUI. * [**User**](/impossible-cloud-help/security/identity-access-management-iam/managing-users): A specific account with a dedicated login mail and password. This can either be a root user or a sub-user. A user represents an individual that can access the Impossible Cloud Storage Console. For instance, an employee in a marketing department. {% hint style="info" %} Currently, every organization will receive **one root user** with the ability to manage identity and access for their organization. {% endhint %} * [**Policy**](/impossible-cloud-help/security/identity-access-management-iam/managing-policies): A **set of permissions** defining what individuals can see and do. These rules are defined on a group level, which consists of dedicated users. For instance, this could comprise of permissions for the marketing department to access marketing-relevant content. * [**Group**](/impossible-cloud-help/security/identity-access-management-iam/managing-groups): A representation of an **organizational unit** comprising of user accounts assigned to selected policies. For instance, this could be a marketing department. ## Supported IAM Features To provide true S3 compatibility, our object storage supports all S3 actions and effects. This means that permissions can be assigned at the most granular level. For instance: * **List**: Shows a list of buckets authorized for the respective group. This is a minimum requirement for any sub-user in that group to see the assigned buckets. * **Read**: This allows the assigned group's sub-users to retrieve objects with their previous versions and configurations (e.g. object lock status, retention periods, and legal hold status). * **Write**: This allows sub-users of the assigned group to delete and/or add an object to a bucket. Refer to AWS documentation on S3 [actions ](https://docs.aws.amazon.com/AmazonS3/latest/API/API_Operations.html)and [effects ](https://docs.aws.amazon.com/IAM/latest/UserGuide/reference_policies_elements_effect.html)for more details. # Types of IAM Policies **Impossible Cloud supports IAM policies** that allow its users to **have granular control over the use, access and administration of their cloud storage.** Currently the Impossible Cloud Console can manage the following types of policies:
* **Managed Policies** * **IC Managed Policies** * **Inline Policies** An **inline policy** is attached directly to a specific IAM user.\ If that user is deleted, the inline policy is deleted too, it can’t be reused. A **managed policy** exists as its own separate item in IAM.\ If the group or user it’s linked to is deleted, the policy still exists and can be attached to another IAM user. ## 1. Managed Policies Managed Policies are a reusable set of permissions that you can attach to multiple users or groups to control what actions they can perform.\ \ Impossible Cloud allows you to have custom policies created and managed by you. Customer managed policies offer greater flexibility as you can define specific permissions based on your requirements. You can also reuse these policies across multiple users or groups within your ICSC environment. You can either put this in a .JSON file and attach it via CLI, or create it in the ICSC console under “Policies” using the [Visual Policy Builder](/impossible-cloud-help/security/identity-access-management-iam/managing-policies/visual-policy-builder) or the JSON editor. A Managed Policy can look like this: **File example: my-impossible-cloud-policy.json** ```json { "Statement": [ { "Action": [ "s3:ListAllMyBuckets", "s3:PutObject", "s3:ListBucket" ], "Effect": "Allow", "Resource": [ "arn:aws:s3:::my-impossible-cloud-bucket", "arn:aws:s3:::my-impossible-cloud-bucket/*" ], "Sid": "AllowCommonS3Actions" } ], "Version": "2012-10-17" } ``` {% hint style="info" %} This policy lets the assigned user(s) see and upload files to the bucket "my-impossible-cloud-bucket". However it restricts their permission to download or delete any objects within. {% endhint %} #### Remember to configure your profile: ``` aws configure --profile your-profile-name ``` **To attach that Managed Policy to an IAM User using CLI, you can write:** ```sh aws iam create-policy \ --policy-name MyICPolicy \ --policy-document file://my-impossible-cloud-policy.json \ --endpoint-url https://iam.impossibleapi.net \ --profile your-profile-name aws iam attach-user-policy \ --user-name "user-name@yourdomain.com" \ --policy-arn arn:aws:iam::123456789012:policy/MyICPolicy \ --endpoint-url https://iam.impossibleapi.net/ --profile your-profile-name ``` ## 2. IC Managed Policies IC Managed Policies are pre-defined and maintained by Impossible Cloud. They provide ready-to-use permission sets that can be attached to IAM users and groups. Use IC Managed Policies when you want a standardized policy maintained by Impossible Cloud, instead of creating and maintaining your own custom managed policy. ### How to access IC Managed Policies You can access IC Managed Policies via: * **CLI:** Use IAM policy discovery commands against the IAM endpoint to list and inspect available managed policies. IC managed policies use the path prefix `/ic` and their ARNs do not include an account ID. #### CLI examples List policies: Use the AWS scope value for provider-managed policies: ```sh aws iam list-policies \ --scope AWS \ --endpoint-url https://iam.impossibleapi.net \ --profile your-profile-name ``` Attach a selected policy to a user: ```sh aws iam attach-user-policy \ --user-name "user-name@yourdomain.com" \ --policy-arn arn:aws:iam::1:policy/ICManagedPolicyName \ --endpoint-url https://iam.impossibleapi.net \ --profile your-profile-name ``` {% hint style="info" %} Tip: For IC managed policies, keep the account ID `1` in the policy ARN and replace only `ICManagedPolicyName`. {% endhint %} ## 3. Inline Policies Inline policies are directly embedded into a single IAM user or group. These type of policies have the following conditions:
* **Directly Attached:** When you create an inline policy, it becomes part of that specific user or group. * **Unique to the Identity:** It cannot be attached to any other user or group. * **No Versioning:** Unlike managed policies, inline policies do not have versioning, meaning you can't easily roll back to a previous version of the policy. * **Lifecycle:** If you delete the IAM identity, the inline policy is also automatically deleted.
{% hint style="info" %} Note: While inline policies provide granular control, they are not reusable across different users or groups like the Managed Policies. {% endhint %} You can assign inline policies via CLI like this: ```sh aws iam put-user-policy \ --user-name "user-name@yourdomain.com" \ --policy-name CustomInlinePolicy \ --policy-document file://my-impossible-cloud-policy.json \ --endpoint-url https://iam.impossibleapi.net/ \ --profile your-profile-name ``` {% hint style="info" %} Alternatively, this can be done in the UI in the User > Select User > Inline Policies section. {% endhint %} # Managing Users When accessing the Impossible Cloud Storage Console as a root user, you can create sub-users to give other people access to the console. The U**sers** tab serves as the single-source-of-truth for all users registered in your organization. You can **add, filter,** and **delete users** (sub-users) as well as edit the assigned rights, including assigning group memberships, tags, inline policies, access keys, and console access. {% hint style="info" %} The **Users** tab is only available for root users - and accordingly also conducting any of the above actions. {% endhint %} ## Creating a User To add users, follow these instructions: 1. Navigate to the **Users** tab on the left-pane. 2. Click on the **Add User** button on the top-right of the console. * Fill in the required **email** * **(optional)** Fill in **password** to give them access to the console. {% hint style="warning" %} Filling in password for sub-users is only applicable when you want to enable console access for the user. The email and password you set up in this section will be used to login to ICSC. Read our knowledge base article about [How to Use Console Access for Secure Access Management](https://kb.impossiblecloud.com/en/how-to-use-the-console-access-feature-in-icsc) to learn more. {% endhint %} * **Inform the recipient** about the account details. ## Deleting a User To delete users, follow these instructions: 1. Navigate to the **Users** tab on the left-pane. 2. Click on the **delete icon** next to the user. 3. **Confirm** the deletion. ## Managing Users as a Root User The **root user** has full administrative control, including the ability to manage access and permissions for all sub-users in the account. This includes assigning permissions, managing access keys, and updating user metadata such as tags. Permissions for sub-users can be managed in two ways: * **Group-Based Policies**: Sub-users assigned to one or more groups will automatically inherit the permissions defined by the policies attached to those groups. * **Inline Policies**: Alternatively, policies can be assigned directly to individual users through inline policies. This allows for more granular permission control when group-based management is not sufficient. Additionally, the root user can also **create or delete access keys** for any sub-user. This facilitates easier key rotation and credential management without requiring direct login access to the sub-user's account. To manage a sub-user’s settings: 1. Navigate to the **Users** tab in the Console. 2. Click on the desired sub-user to open their management panel. 3. Use the available tabs — **Groups**, **Tags**, **Access Keys**, and **Inline Policies** — to manage each aspect of the sub-user's configuration. These tools give the root user fine-grained control over user permissions and credentials, helping enforce security and compliance standards efficiently.
# Managing Groups In Impossible Cloud Storage, g**roups** are used to define and manage access permissions for specific resources. These groups follow the **Industry S3 policy standard**, ensuring compatibility and familiarity for users with experience in other environments. By linking a list of users with one or more policies, a Group enables role-based access control at Impossible Cloud Storage Console. For instance, access for group of user in the same department can be restricted to only a list of buckets. The Group management at Impossible Cloud Storage Console can be done in **Groups** tab. From there, you can **add, filter** and **delete groups** as well as edit each group's **assigned users** and **policies**. The **Groups** tab is only visible for root users - and accordingly, also conducting any of the above actions. ## Creating a Group To **add groups**, follow these instructions: 1. Navigate to the **Groups** tab 2. Click the **Add Group** button on the top-right of the console. * Fill in the **Group Name**. * (Optional) Assign users and policies that you want to apply. These details can be added/edited later. {% hint style="info" %} Group's name cannot be updated. However, the list of Users and Policies can be edited at anytime. {% endhint %} ## Editing a Group To edit a **group,** follow these instructions: 1. **N**avigate to the **Groups** tab 2. **Click** the respective button next to the group you want to edit. 3. **Edit** the Group's members or the assigned policies. 4. Finish the update by Clicking **Save** at the top-right corner of the page. ## Deleting a Group To delete a group, follow these instructions: 1. Navigate to the **Group** tab in left-pane menu. 2. Click on the **Delete** button next to the group. 3. **Confirm** the deletion. # Managing Policies In Impossible Cloud Storage, **IAM policies** are used to define and manage access permissions for specific resources. These policies follow the **Industry S3 policy standard**, ensuring compatibility and familiarity for users with experience in other environments. Each policy is stored in **JSON format**, but the Storage Console lets you author policies through a visual interface or by writing the JSON directly. IAM Policy management at Impossible Cloud Storage Console can be done in **Policies** tab. From there, you can **add, filter, delete** as well as **edit** an existing policy. The **Policies** tab is only visible for root users - and accordingly, also conducting any of the above actions. ## Creating a Policy The Impossible Cloud Storage Console offers two ways to author a policy. Use the **Visual Policy Builder** to configure statements through dropdowns and search fields, or the **JSON editor** to write the raw policy document directly. A **Visual | JSON** toggle at the top of the policy editor switches between them, and both views share the same underlying policy. For a full walkthrough, see [Visual Policy Builder](/impossible-cloud-help/security/identity-access-management-iam/managing-policies/visual-policy-builder). To create a policy, follow these instructions: 1. Navigate to the **Policies** tab in left-pane menu. 2. Click the **Add Policy** button on the top-right of the console. * Fill in the **Policy name** * (Optional) Fill in the **description** of the policy. {% hint style="info" %} The policy name must consist of alphanumeric characters (upper and lowercase) with no spaces. Once created, the policy name and description cannot be changed. {% endhint %} 3. Select a mode with the **Visual | JSON** toggle, then **define** the policy. Use the **Visual Policy Builder** for a guided, statement-based interface, or the **JSON editor** to write the policy document directly. 4. Click **Create Policy** on the top-right corner of your screen to confirm the creation of the policy. ## Updating a Policy When you update a policy in the Impossible Cloud Storage Console, a new version of that policy is automatically created. This versioning system allows you to easily revert to a previous version if needed. To **edit a policy**, follow these instructions: 1. Navigate to the **Policies** tab in left-pane menu. 2. Click the **Edit** button next to the policy you want to modify. 3. You can **edit** the policy in either Visual or JSON mode, just like when creating a new policy. 4. Click the **Save** button in the top-right corner to create a new version. 5. Click on the newly created version and **set it as the default** to activate the version. {% hint style="info" %} The Storage Console supports a maximum of 5 (five) policy versions. If this limit is reached, you must delete an existing version before creating a new one. {% endhint %} ## Deleting a Policy Deleting a policy will automatically remove the access and permissions for the corresponding group(s) of users. To delete a policy, follow these instructions: 1. Navigate to the **Policies** tab in left-pane menu. 2. Click on the **Delete** button next to the policy. 3. **Confirm** the deletion.
# Visual Policy Builder The **Visual Policy Builder** is a graphical interface for creating and editing IAM policies without writing raw JSON. It organizes a policy into individual **statements**, each of which you configure through dropdowns and search fields. You can switch between Visual and JSON modes at any time - both views share the same underlying policy document. ## Switching Between Visual and JSON Mode When creating or editing a policy, a **Visual | JSON** toggle appears at the top of the policy editor. Click **Visual** to use the Visual Policy Builder, or **JSON** to edit the raw policy document directly. ## Quick apply on bucket(s) At the top of the Visual Policy Builder, the **Quick apply on bucket(s)** presets populate an entire statement in one click: | Preset | What it creates | | ---------------- | --------------------------------------------------------------------------------- | | **Read only** | `s3:Get*` and `s3:List*` actions on a selected bucket and its objects | | **Read & write** | `s3:Get*`, `s3:List*`, and `s3:Put*` actions on a selected bucket and its objects | | **Full access** | All `s3:*` actions on a selected bucket and its objects | Clicking a preset opens a bucket selection modal. Select one or more buckets and confirm - the builder automatically creates the correct ARNs for both bucket-level and object-level resources. ## Working with Statements A policy is composed of one or more **statements**. Each statement appears as a collapsible card. Use the buttons on the right side of each card to: * **Move up / Move down** - reorder statements within the policy * **Duplicate** - copy the statement * **Clear / Delete** - clears the statement's fields when the policy has a single statement, or deletes the statement when it has more than one Click **Add Statement** at the bottom of the builder to append a new empty statement. ### Effect Each statement starts with an **Effect** selector. Choose: * **Allow** - grant the listed actions on the listed resources * **Deny** - explicitly block the listed actions, overriding any Allow ### Actions The **Actions** section lets you choose which S3 or IAM operations the statement covers. **Filtering by service:** Use the **All / S3 / IAM / STS** tabs to narrow the action list by service. **Searching:** Type in the search box to filter actions by name or description. **Action presets:** Click **Presets** to open a menu of predefined action groups, then select one: | Preset | Actions included | | --------------------- | ------------------------------------------------------------ | | S3 Read Only | `s3:Get*`, `s3:List*` | | S3 Read/Write | `s3:Get*`, `s3:List*`, `s3:Put*` | | S3 Full Access | `s3:*` | | IAM User Management | IAM actions for creating and managing users | | IAM Group Management | IAM actions for creating and managing groups | | IAM Policy Management | IAM actions for creating and managing policies | | Console UI | Actions required to use the Impossible Cloud Storage Console | | IAM Read Only | Read-only IAM actions | **Custom actions:** Enter a wildcard pattern such as `s3:Get*` or `iam:*` in the custom action field and press Enter to add it. {% hint style="info" %} Use the **Selected only** toggle to filter the action list down to only the actions you have already checked. This makes it easy to review your selection before saving. {% endhint %} ### Resources The **Resources** section defines which resources the statement applies to. You can specify resources in two ways: **Quick templates:** Click a template button to insert a pre-built ARN pattern. The templates are: * **All resources** (`*`) * **All S3 resources** (`arn:aws:s3:::*`) * **All IAM users**, **All IAM groups**, **All IAM policies** * **Specific bucket** (`arn:aws:s3:::my-bucket`) * **Bucket objects** (`arn:aws:s3:::my-bucket/*`) * **Bucket + objects** (both the bucket and its objects) **Custom ARN:** Enter an ARN directly in the input field and press Enter. Values must be `*`, start with `arn:`, or follow standard ARN syntax. ### Conditions Conditions are optional restrictions that must be met for the statement to apply. Expand **Conditions (optional)**, then click **Add condition**. Each condition has three parts: * **Operator** - how the value is evaluated. The visual builder offers `IpAddress`, `NotIpAddress`, `StringEquals`, and `StringLike`. * **Context key** - the key to evaluate, either `aws:SourceIp` or `aws:username`. * **Value** - one or more values (comma-separated for OR matching) Example: * **Restrict by IP address:** Operator `IpAddress`, Context key `aws:SourceIp`, Value `203.0.113.0/24` For condition operators beyond these four, switch to the JSON editor. ## Creating a Policy Using the Visual Builder 1. Navigate to the **Policies** tab in the left-pane menu. 2. Click **Add Policy** in the top-right corner. 3. Enter a **Policy name** and an optional **description**. {% hint style="info" %} The policy name must consist of alphanumeric characters (upper and lowercase) with no spaces. Once created, the policy name and description cannot be changed. {% endhint %} 4. Click **Visual** in the mode toggle to switch to the Visual Policy Builder. 5. Configure the first statement: * Select an **Effect** (Allow or Deny). * Select the **Actions** the statement should cover. * Add the **Resources** the statement applies to. * Optionally add **Conditions**. 6. Click **Add Statement** to add additional statements if needed. 7. Click **Create Policy** in the top-right corner to save. ## Editing a Policy Using the Visual Builder 1. Navigate to the **Policies** tab in the left-pane menu. 2. Click **Edit** next to the policy you want to modify. 3. Click **Visual** in the mode toggle if the JSON editor is currently active. 4. Edit any statement by updating its Effect, Actions, Resources, or Conditions, or click **Add Statement** to add a new one. 5. Click **Save** in the top-right corner to create a new version. 6. Click on the newly created version and **set it as the default** to activate it. {% hint style="info" %} The Storage Console supports a maximum of 5 policy versions. If this limit is reached, you must delete an existing version before saving a new one. {% endhint %} # Policy Conditions ### Policy Conditions In addition to controlling *which actions* users can perform, you can also control *under what circumstances* those actions are allowed. Policy conditions let you add extra requirements that must be met before access is granted. #### IP Address Conditions One of the most useful conditions is restricting access based on the client's IP address. This is ideal for: * Limiting bucket access to your corporate network * Ensuring backups only run from designated servers * Meeting compliance requirements for data access controls **IpAddress Condition** The `IpAddress` condition allows access only when requests come from specified IP addresses or ranges: ```json { "Version": "2012-10-17", "Statement": [ { "Effect": "Allow", "Action": "s3:*", "Resource": [ "arn:aws:s3:::my-bucket", "arn:aws:s3:::my-bucket/*" ], "Condition": { "IpAddress": { "aws:SourceIp": "203.0.113.0/24" } } } ] } ``` This policy grants access only to requests originating from the 203.0.113.0/24 network. **NotIpAddress Condition** The `NotIpAddress` condition allows access from all IP addresses *except* those specified: ```json "Condition": { "NotIpAddress": { "aws:SourceIp": "198.51.100.0/24" } } ``` **Supported CIDR Ranges Examples** IP addresses must be specified using CIDR notation: * `/32` — Single IP (e.g., `203.0.113.25/32`) * `/24` — Class C network (e.g., `203.0.113.0/24`) * `/16` — Class B network (e.g., `203.0.0.0/16`) * `/8` — Class A network (e.g., `203.0.0.0/8`) * `/0` — All addresses (e.g., `0.0.0.0/0`) For detailed examples and step-by-step instructions, see How to Restrict Bucket Access by IP Address. *** # String Conditions and s3:prefix String conditions let you restrict access based on the value of a string in the request context. The most useful pairing for S3 is a string operator on the `s3:prefix` context key, which scopes `s3:ListBucket` to a folder inside a bucket. For IP-based conditions, see [Policy Conditions](/impossible-cloud-help/security/identity-access-management-iam/managing-policies/policy-conditions). ## When to use string conditions Use a string condition on `s3:prefix` to: * Limit a user to listing objects under a specific folder. * Give each user a private folder inside a shared bucket using `${aws:username}`. * Block listing of a sensitive sub-folder with an explicit `Deny`. For the step-by-step how-to with copy-paste policies, see [Restrict an IAM user to a folder](/impossible-cloud-help/security/identity-access-management-iam/managing-policies/restrict-iam-user-to-a-folder). ## Supported string operators | Operator | Match semantics | | --------------------------- | ----------------------------------------------------------------------------- | | `StringEquals` | Exact match. Case-sensitive. | | `StringNotEquals` | Exact non-match. Case-sensitive. | | `StringEqualsIgnoreCase` | Exact match. Case-insensitive. | | `StringNotEqualsIgnoreCase` | Exact non-match. Case-insensitive. | | `StringLike` | Wildcards. `*` matches any run of characters, `?` matches a single character. | | `StringNotLike` | Wildcard non-match. | Each operator takes a context key and one or more values. Wildcards are only interpreted in `StringLike` and `StringNotLike` patterns. The matcher treats the request value as a literal byte sequence: no URL decoding, no Unicode normalization, no path normalization. ### Example ```json { "Version": "2012-10-17", "Statement": [{ "Effect": "Allow", "Action": "s3:ListBucket", "Resource": "arn:aws:s3:::my-bucket", "Condition": { "StringLike": { "s3:prefix": "team-data/projectA/*" } } }] } ``` This statement allows `s3:ListBucket` only when the request's `--prefix` parameter starts with `team-data/projectA/`. Every other request is denied. ## Modifier suffix: ...IfExists Append `IfExists` to any string operator to make the condition pass when the context key is absent: * `StringEqualsIfExists` * `StringLikeIfExists` * `StringNotLikeIfExists` With `IfExists`, a request that omits `--prefix` passes the condition. Without `IfExists`, the same request is denied because the context key is treated as missing. ```json "Condition": { "StringLikeIfExists": { "s3:prefix": "team-data/projectA/*" } } ``` ## Set-operator prefixes: ForAllValues, ForAnyValue Multi-valued context keys (currently rare for `s3:prefix`, common for future keys) are evaluated with set semantics: * `ForAllValues:StringLike` - every value in the context must match at least one pattern. * `ForAnyValue:StringLike` - at least one value in the context must match a pattern. These prefixes attach to any string operator. Example: ```json "Condition": { "ForAnyValue:StringLike": { "s3:prefix": ["team-data/projectA/*", "team-data/projectB/*"] } } ``` {% hint style="warning" %} **ForAllValues on an absent context key denies on Impossible Cloud.** The AWS specification says `ForAllValues:` is vacuously true when the context key is absent. Impossible Cloud's evaluator denies in that case as a defense-in-depth choice. If you write `ForAllValues:StringLike { s3:prefix: ... }` as your only Allow, requests without a `--prefix` will return 403 AccessDenied. {% endhint %} ## Policy variables in condition values Variables expand inside Condition values, not only inside Resource ARNs. The supported variable is: | Variable | Resolves to | | ----------------- | ---------------------------------------------------------------------------------------------------------------------------------------------- | | `${aws:username}` | The calling IAM user's full username. On Impossible Cloud this is the email address used to create the user (for example `alice@example.com`). | The resolved value is treated as a literal string. Special characters such as `+`, `@`, and `.` round-trip without URL encoding. ### Example: per-user folder isolation ```json { "Version": "2012-10-17", "Statement": [{ "Effect": "Allow", "Action": "s3:ListBucket", "Resource": "arn:aws:s3:::my-bucket", "Condition": { "StringLike": { "s3:prefix": "user-data/${aws:username}/*" } } }] } ``` Each user can list only their own folder under `user-data//`. ## The s3:prefix context key `s3:prefix` is populated from the `prefix` query parameter on `ListObjectsV2`. The key is present when the client sends `--prefix ` with a non-empty value. The key is treated as absent when the client omits `--prefix` or sends `--prefix ""`. `s3:prefix` is available on `s3:ListBucket` actions. The context key is **not** populated for `s3:ListBucketVersions` or `s3:ListMultipartUploads`. A policy using `StringLike` on `s3:prefix` for those actions denies even when the request prefix matches. ## Combining conditions Multiple condition keys inside one `Condition` block are joined with AND. All must hold for the statement to apply. ```json "Condition": { "IpAddress": { "aws:SourceIp": "203.0.113.0/24" }, "StringLike": { "s3:prefix": "user-data/${aws:username}/*" } } ``` This statement requires both the source IP and the prefix to match. Either failing denies the request. Multiple statements in one policy union with OR for Allow, and explicit Deny wins over Allow. See [Restrict an IAM user to a folder](/impossible-cloud-help/security/identity-access-management-iam/managing-policies/restrict-iam-user-to-a-folder) for the canonical Allow + Deny pattern that blocks a sensitive sub-folder. ## Operators not yet evaluated The following operators parse without an error but evaluate as always-false, so policies using them deny every request: * Numeric operators: `NumericEquals`, `NumericNotEquals`, `NumericLessThan`, `NumericLessThanEquals`, `NumericGreaterThan`, `NumericGreaterThanEquals` * Date operators: `DateEquals`, `DateNotEquals`, `DateLessThan`, `DateLessThanEquals`, `DateGreaterThan`, `DateGreaterThanEquals` * Boolean operator: `Bool` * ARN operators: `ArnEquals`, `ArnLike` * Binary operator: `BinaryEquals` If you need behavior that one of these would normally provide, rewrite the policy using `IpAddress` or one of the supported string operators. ## See also * [Policy Conditions](/impossible-cloud-help/security/identity-access-management-iam/managing-policies/policy-conditions) - IP address conditions (`IpAddress`, `NotIpAddress`). * [Restrict an IAM user to a folder](/impossible-cloud-help/security/identity-access-management-iam/managing-policies/restrict-iam-user-to-a-folder) - tutorial with copy-paste policies. * [Types of IAM Policies](/impossible-cloud-help/security/identity-access-management-iam/types-of-iam-policies) - inline vs managed. # Restrict an IAM user to a folder A common use case for Impossible Cloud Storage is a shared bucket where each user (or team) can only see and work with their own folder. This guide shows the two policy patterns that handle this, both verified end-to-end. The patterns rely on string conditions and the `s3:prefix` context key. For the operator reference, see [String Conditions and s3:prefix](/impossible-cloud-help/security/identity-access-management-iam/managing-policies/string-conditions-and-prefix). ## Choose a pattern | Pattern | Use when | | ----------------------------------------- | --------------------------------------------------------------------------------------------------------------------- | | **Hardcoded prefix per user or role** | Each user or team has a fixed folder name that does not match their username. Easiest to read; one policy per folder. | | **Per-user folder via `${aws:username}`** | Every user gets a folder named after their username (their email). One policy serves all users. | Both patterns expose the user's full subtree under the allowed folder, including nested objects, and deny everything outside it. ## Pattern A - Hardcoded prefix Attach this inline policy to a user who should only see `team-data/projectA/`: ```json { "Version": "2012-10-17", "Statement": [ { "Sid": "AllowListProjectA", "Effect": "Allow", "Action": "s3:ListBucket", "Resource": "arn:aws:s3:::my-bucket", "Condition": { "StringLike": { "s3:prefix": "team-data/projectA/*" } } }, { "Sid": "AllowReadWriteProjectA", "Effect": "Allow", "Action": ["s3:GetObject", "s3:PutObject"], "Resource": "arn:aws:s3:::my-bucket/team-data/projectA/*" } ] } ``` The first statement scopes listing to the `team-data/projectA/` folder. The second statement permits read and write on the objects inside it. Replace `my-bucket` with your bucket name and `team-data/projectA/` with your folder. ### Attach the policy via AWS CLI ```bash aws iam put-user-policy \ --user-name alice@example.com \ --policy-name AllowProjectAOnly \ --policy-document file://policy.json \ --endpoint-url https://iam.impossibleapi.net \ --region eu-central-2 ``` Wait up to 90 seconds for the policy to propagate before testing. ### Test the policy List inside the allowed folder: ```bash aws s3api list-objects-v2 \ --bucket my-bucket \ --prefix "team-data/projectA/" \ --endpoint-url https://eu-central-2.storage.impossibleapi.net \ --region eu-central-2 ``` The response includes every object under `team-data/projectA/`, including nested keys such as `team-data/projectA/sub/file.txt` and `team-data/projectA/deep/nested/file.txt`. The result is paginated when there are more than 1000 keys. Download an object: ```bash aws s3 cp s3://my-bucket/team-data/projectA/notes.txt ./notes.txt \ --endpoint-url https://eu-central-2.storage.impossibleapi.net \ --region eu-central-2 ``` Upload an object: ```bash aws s3 cp ./report.pdf s3://my-bucket/team-data/projectA/report.pdf \ --endpoint-url https://eu-central-2.storage.impossibleapi.net \ --region eu-central-2 ``` Confirm that listing a different folder is denied: ```bash aws s3api list-objects-v2 \ --bucket my-bucket \ --prefix "team-data/projectB/" \ --endpoint-url https://eu-central-2.storage.impossibleapi.net \ --region eu-central-2 ``` The response is `403 AccessDenied`. ## Pattern B - Per-user folder via ${aws:username} Attach this single inline policy to **every** user who should be confined to `user-data//`: ```json { "Version": "2012-10-17", "Statement": [ { "Sid": "AllowListOwnFolder", "Effect": "Allow", "Action": "s3:ListBucket", "Resource": "arn:aws:s3:::my-bucket", "Condition": { "StringLike": { "s3:prefix": "user-data/${aws:username}/*" } } }, { "Sid": "AllowReadWriteOwnFolder", "Effect": "Allow", "Action": ["s3:GetObject", "s3:PutObject"], "Resource": "arn:aws:s3:::my-bucket/user-data/${aws:username}/*" } ] } ``` `${aws:username}` resolves at request time to the caller's IAM username. On Impossible Cloud, the username is the email address used to create the user, so for a user `alice@example.com` the pattern expands to `user-data/alice@example.com/*`. Both statements use the same variable, so each user automatically reads and writes only their own folder. ### Test from each user Sign in as `alice@example.com` and run: ```bash aws s3api list-objects-v2 \ --bucket my-bucket \ --prefix "user-data/alice@example.com/" \ --endpoint-url https://eu-central-2.storage.impossibleapi.net \ --region eu-central-2 ``` The response lists alice's full subtree. Now try to list bob's folder from alice's credentials: ```bash aws s3api list-objects-v2 \ --bucket my-bucket \ --prefix "user-data/bob@example.com/" \ --endpoint-url https://eu-central-2.storage.impossibleapi.net \ --region eu-central-2 ``` The response is `403 AccessDenied`. Bob's folder is invisible to alice. ## Combining with an IP restriction To require both a specific source network and the prefix, add an `IpAddress` condition inside the same `Condition` block. Both conditions then must hold (AND). ```json "Condition": { "IpAddress": { "aws:SourceIp": "203.0.113.0/24" }, "StringLike": { "s3:prefix": "user-data/${aws:username}/*" } } ``` A request from outside `203.0.113.0/24` is denied even if the prefix matches. See [Policy Conditions](/impossible-cloud-help/security/identity-access-management-iam/managing-policies/policy-conditions) for the full IP condition reference. ## Block a sub-folder with explicit Deny To allow a parent folder but block a sensitive sub-folder, add a second statement with `Effect: Deny`. Explicit `Deny` always wins over `Allow`. ```json { "Version": "2012-10-17", "Statement": [ { "Sid": "AllowListTeamData", "Effect": "Allow", "Action": "s3:ListBucket", "Resource": "arn:aws:s3:::my-bucket", "Condition": { "StringLike": { "s3:prefix": "team-data/*" } } }, { "Sid": "DenyListSecret", "Effect": "Deny", "Action": "s3:ListBucket", "Resource": "arn:aws:s3:::my-bucket", "Condition": { "StringLike": { "s3:prefix": "team-data/secret/*" } } } ] } ``` Listing `team-data/public/` succeeds. Listing `team-data/secret/` returns `403 AccessDenied`. ## Gotchas The matcher compares the request's `--prefix` parameter against the policy pattern as literal strings. The following situations catch first-time users. ### The trailing slash matters `StringLike { s3:prefix: "team-data/projectA/*" }` matches `--prefix "team-data/projectA/"` but does not match `--prefix "team-data/projectA"` (no trailing slash). The pattern requires the literal `team-data/projectA/` prefix in the request value. Always include the trailing slash on the request when the policy pattern includes it. ### The user must always send --prefix A request without `--prefix` is denied because `s3:prefix` is treated as absent and `StringLike` without `IfExists` denies on absent keys. For example: ```bash aws s3api list-objects-v2 \ --bucket my-bucket \ --endpoint-url https://eu-central-2.storage.impossibleapi.net \ --region eu-central-2 ``` The call above returns `403 AccessDenied`. If you need to allow listing without a prefix, use `StringLikeIfExists`: ```json "Condition": { "StringLikeIfExists": { "s3:prefix": "team-data/projectA/*" } } ``` The condition then passes when `--prefix` is missing, and the request is allowed. ### Empty prefix is treated as absent `--prefix ""` is the same as omitting the parameter. Non-`IfExists` conditions deny; `IfExists` conditions allow. ### Nested keys are visible Listing `team-data/projectA/` returns every object below it, regardless of depth. To restrict a user to a single sub-folder, the policy pattern must target that sub-folder, for example `team-data/projectA/public/*`. ### Usernames are emails `${aws:username}` resolves to the full email used at user creation, including `@` and any `+` tag. The pattern `user-data/${aws:username}/*` therefore expands to `user-data/alice@example.com/*`. The matcher does not URL-decode the request value, so the request must use the same literal characters. ## Common mistakes | Symptom | Cause | Fix | | ----------------------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | All requests return 403, even the allowed prefix. | Operator name typo (for example `StringLikes` or `StringLIKE`). The policy parses but never matches. | Use the exact operator names listed in [String Conditions and s3:prefix](/impossible-cloud-help/security/identity-access-management-iam/managing-policies/string-conditions-and-prefix#supported-string-operators). | | The first list works, the next one is denied. | The first request included `--prefix`, the next did not. `s3:prefix` is then absent and the condition denies. | Always pass `--prefix` or switch the condition to `StringLikeIfExists`. | | `StringEquals { s3:prefix: "Team-Data/" }` denies a request with `--prefix "team-data/"`. | `StringEquals` is case-sensitive. | Use `StringEqualsIgnoreCase` if the case should not matter. | | Adding an `IpAddress` condition broke an `s3:ListBucket` policy that was working. | Conditions inside one `Condition` block AND together. The request must now satisfy both. | Remove the IP condition, split into two statements, or update the allowed CIDR. | | A policy using `NumericEquals` or `DateGreaterThan` denies every request. | These operators are not yet evaluated and behave as always-false. | Rewrite using a supported string or IP operator. See the operators-not-yet-evaluated section of [String Conditions and s3:prefix](/impossible-cloud-help/security/identity-access-management-iam/managing-policies/string-conditions-and-prefix#operators-not-yet-evaluated). | ## See also * [String Conditions and s3:prefix](/impossible-cloud-help/security/identity-access-management-iam/managing-policies/string-conditions-and-prefix) - reference for operators, modifiers, and variables. * [Policy Conditions](/impossible-cloud-help/security/identity-access-management-iam/managing-policies/policy-conditions) - IP address conditions. * [Managing Policies](/impossible-cloud-help/security/identity-access-management-iam/managing-policies) - creating, updating, and deleting policies in the Storage Console. # CORS support Cross-Origin Resource Sharing, or CORS, is a process that allows web applications from one domain to interact with resources from a different domain. ## Example of using CORS Let's illustrate CORS with a simple example. Imagine you have a bucket full of pictures in Impossible Cloud Storage. You also have a website that lets your users browse these pictures. Essentially, your website (let's say, "mysite.com") is connected to your Impossible Cloud Storage bucket. But there's a catch - web browsers have safety measures. They don't like it when a website tries to load content from a different domain. In this case, your website "mysite.com" is trying to fetch pictures from Impossible Cloud Storage, which is a different domain. This is where CORS comes in. By setting up CORS on your Impossible Cloud Storage bucket, you're telling the browsers, "It's OK, mysite.com is allowed to access these pictures." With CORS, the browser will happily display your photos to your users. Without CORS, your users would be staring at a blank screen instead of admiring your stunning pictures. That's why CORS is important for connecting your Impossible Cloud Storage with your web application. # Limitations Currently, the ability to configure Cross-Origin Resource Sharing (CORS) is only available through the AWS Command Line Interface (CLI) utility. Unfortunately, there is no user interface option available for setting up CORS in our platform at this time. If you need help getting started with the AWS CLI utility or need to familiarize yourself with how to set up CORS configurations using this tool, we recommend checking out the official AWS guide. You'll find examples of the cors-configuration file [here](https://awscli.amazonaws.com/v2/documentation/api/latest/reference/s3api/put-bucket-cors.html). # CORS Configuration Setting up CORS involves using the aws command-line interface (CLI) utility and working with a few commands. Here are the commands you'll be using: * **get-bucket-cors**: Retrieve the current CORS configuration for your bucket. * **put-bucket-cors**: Apply a new CORS configuration to your bucket. * **delete-bucket-cors**: Remove the existing CORS configuration from your bucket. #### Using the CLI for CORS Configuration We understand that these commands might sound technical. But don't worry, we've got handy CLI examples [here](/impossible-cloud-help/impossible-cloud-storage-guide/cli-user-guide/aws-cli-commands-1/examples#operations-with-cors). Remember, setting up CORS correctly helps secure your data and allows for safe interaction between your bucket and other websites.
