# Amazon managed policies for CodeCommit
<a name="security-iam-awsmanpol"></a>

To add permissions to users, groups, and roles, it is easier to use Amazon managed policies than to write policies yourself. It takes time and expertise to [create IAM customer managed policies](https://docs.amazonaws.cn/IAM/latest/UserGuide/access_policies_create-console.html) that provide your team with only the permissions they need. To get started quickly, you can use our Amazon managed policies. These policies cover common use cases and are available in your Amazon Web Services account. For more information about Amazon managed policies, see [Amazon managed policies](https://docs.amazonaws.cn/IAM/latest/UserGuide/access_policies_managed-vs-inline.html#aws-managed-policies) in the *IAM User Guide*.

Amazon services maintain and update Amazon managed policies. You can't change the permissions in Amazon managed policies. Services occasionally add additional permissions to an Amazon managed policy to support new features. This type of update affects all identities (users, groups, and roles) where the policy is attached. Services are most likely to update an Amazon managed policy when a new feature is launched or when new operations become available. Services do not remove permissions from an Amazon managed policy, so policy updates won't break your existing permissions.

Additionally, Amazon supports managed policies for job functions that span multiple services. For example, the **ReadOnlyAccess** Amazon managed policy provides read-only access to all Amazon services and resources. When a service launches a new feature, Amazon adds read-only permissions for new operations and resources. For a list and descriptions of job function policies, see [Amazon managed policies for job functions](https://docs.amazonaws.cn/IAM/latest/UserGuide/access_policies_job-functions.html) in the *IAM User Guide*.

Amazon addresses many common use cases by providing standalone IAM policies that are created and administered by Amazon. These Amazon managed policies grant required permissions for common use cases. The managed policies for CodeCommit also provide permissions to perform operations in other services, such as IAM, Amazon SNS, and Amazon CloudWatch Events, as required for the responsibilities for the users who have been granted the policy in question. For example, the AWSCodeCommitFullAccess policy is an administrative-level user policy that allows users with this policy to create and manage CloudWatch Events rules for repositories (rules whose names are prefixed with `codecommit`) and Amazon SNS topics for notifications about repository-related events (topics whose names are prefixed with `codecommit`), as well as administer repositories in CodeCommit. 

The following Amazon managed policies, which you can attach to users in your account, are specific to CodeCommit.

## Amazon managed policy: AWSCodeCommitFullAccess
<a name="managed-policies-full"></a>

You can attach the `AWSCodeCommitFullAccess` policy to your IAM identities. This policy grants full access to CodeCommit. Apply this policy only to administrative-level users to whom you want to grant full control over CodeCommit repositories and related resources in your Amazon Web Services account, including the ability to delete repositories.

The AWSCodeCommitFullAccess policy contains the following policy statement:

## Amazon managed policy: AWSCodeCommitPowerUser
<a name="managed-policies-poweruser"></a>

You can attach the `AWSCodeCommitPowerUser` policy to your IAM identities. This policy allows users access to all of the functionality of CodeCommit and repository-related resources, except it does not allow them to delete CodeCommit repositories or create or delete repository-related resources in other Amazon services, such as Amazon CloudWatch Events. We recommend that you apply this policy to most users.

The AWSCodeCommitPowerUser policy contains the following policy statement:

## Amazon managed policy: AWSCodeCommitReadOnly
<a name="managed-policies-read"></a>

You can attach the `AWSCodeCommitReadOnly` policy to your IAM identities. This policy grants read-only access to CodeCommit and repository-related resources in other Amazon services, as well as the ability to create and manage their own CodeCommit-related resources (such as Git credentials and SSH keys for their IAM user to use when accessing repositories). Apply this policy to users to whom you want to grant the ability to read the contents of a repository, but not make any changes to its contents.

The AWSCodeCommitReadOnly policy contains the following policy statement:
