Amazon managed policy for power users - Amazon Key Management Service
Services or capabilities described in Amazon Web Services documentation might vary by Region. To see the differences applicable to the China Regions, see Getting Started with Amazon Web Services in China (PDF).

Amazon managed policy for power users

You can use the AWSKeyManagementServicePowerUser managed policy to give IAM principals in your account the permissions of a power user. Power users can create KMS keys, use and manage the KMS keys they create, and view all KMS keys and IAM identities. Principals who have the AWSKeyManagementServicePowerUser managed policy can also get permissions from other sources, including key policies, other IAM policies, and grants.

AWSKeyManagementServicePowerUser is an Amazon managed IAM policy. For more information about Amazon managed policies, see Amazon managed policies in the IAM User Guide.

Note

Permissions in this policy that are specific to a KMS key, such as kms:TagResource and kms:GetKeyRotationStatus, are effective only when the key policy for that KMS key explicitly allows the Amazon Web Services account to use IAM policies to control access to the key. To determine whether a permission is specific to a KMS key, see Amazon KMS permissions and look for a value of KMS key in the Resources column.

This policy gives a power user permissions on any KMS key with a key policy that permits the operation. For cross-account permissions, such as kms:DescribeKey and kms:ListGrants, this might include KMS keys in untrusted Amazon Web Services accounts. For details, see Best practices for IAM policies and Allowing users in other accounts to use a KMS key. To determine whether a permission is valid on KMS keys in other accounts, see Amazon KMS permissions and look for a value of Yes in the Cross-account use column.

To allow principals to view the Amazon KMS console without errors, the principal needs the tag:GetResources permission, which is not included in the AWSKeyManagementServicePowerUser policy. You can allow this permission in a separate IAM policy.

The AWSKeyManagementServicePower managed IAM policy includes the following permissions.

  • Allows principals to create KMS keys. Because this process includes setting the key policy, power s can give themselves and others permission to use and manage the KMS keys they create.

  • Allows principals to create and delete aliases and tags on all KMS keys. Changing a tag or alias can allow or deny permission to use and manage the KMS key. For details, see ABAC for Amazon KMS.

  • Allows principals to get detailed information about all KMS keys, including their key ARN, cryptographic configuration, key policy, aliases, tags, and rotation status.

  • Allows principals to list IAM users, groups, and roles.

  • This policy does not allow principals to use or manage KMS keys that they didn't create. However, they can change aliases and tags on all KMS keys, which might allow or deny them permission to use or manage a KMS key.
