Actions defined by Amazon Key Management Service
You can specify the following actions in the Action element of an IAM
policy statement. Use policies to grant permissions to perform an operation in Amazon. When
you use an action in a policy, you usually allow or deny access to the API operation or CLI
command with the same name. However, in some cases, a single action controls access to more
than one operation. Alternatively, some operations require several different actions.
Permission-only actions for Amazon Key Management Service
The following actions are defined by Amazon Key Management Service but are not directly invocable through any API operation. They can only be used in IAM policy statements to grant or deny permissions.
| Actions | Description | Resource types (*required) | Condition keys | Access level |
|---|---|---|---|---|
Controls access to internal APIs that synchronize multi-Region keys |
Write |
Resource types defined by Amazon Key Management Service
The following resource types are defined by this service and can be used in the
Resource element of IAM permission policy statements.
| Resource types | ARN | Condition keys |
|---|---|---|
arn:${Partition}:kms:${Region}:${Account}:alias/${Alias} |
||
arn:${Partition}:kms:${Region}:${Account}:key/${KeyId} |
