PutResourcePolicy - AWS Systems Manager


Creates or updates a Systems Manager resource policy. A resource policy helps you to define the IAM entity (for example, an AWS account) that can manage your Systems Manager resources. The following resources support Systems Manager resource policies.

  • OpsItemGroup - The resource policy for OpsItemGroup enables AWS accounts to view and interact with OpsCenter operational work items (OpsItems).

  • Parameter - The resource policy is used to share a parameter with other accounts using AWS Resource Access Manager (AWS RAM).

    To share a parameter, it must be in the advanced parameter tier. For information about parameter tiers, see Managing parameter tiers. For information about changing an existing standard parameter to an advanced parameter, see Changing a standard parameter to an advanced parameter.

    To share a SecureString parameter, it must be encrypted with a customer managed key, and you must share the key separately through AWS Key Management Service. AWS managed keys cannot be shared. Parameters encrypted with the default AWS managed key can be updated to use a customer managed key instead. For AWS KMS key definitions, see AWS KMS concepts in the AWS Key Management Service Developer Guide.


    While you can share a parameter using the Systems Manager PutResourcePolicy operation, we recommend using AWS Resource Access Manager (AWS RAM) instead. This is because using PutResourcePolicy requires the extra step of promoting the parameter to a standard AWS RAM Resource Share using the AWS RAM PromoteResourceShareCreatedFromPolicy API operation. Otherwise, the parameter won't be returned by the Systems Manager DescribeParameters API operation using the --shared option.

    For more information, see Sharing a parameter in the AWS Systems Manager User Guide
