# 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 written in **JSON format**, allowing for precise and structured permission definitions.

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

To simplify policy creation, the Impossible Cloud Storage Console includes a built-in JSON editor. This editor provides a convenient interface for writing and editing policies directly within the Console, making it easy to define access rules according to your requirements.

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. **Write** the S3 policy in the built-in JSON editor. 
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 using the Graphical User Interface (GUI) 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 using the built-in JSON editor, 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 remove 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.<br>
