iam-customer-policy-blocked-kms-actions
Checks if the managed AWS Identity and Access Management (IAM) policies that you create do not allow blocked actions on AWS KMS keys. The rule is NON_COMPLIANT if any blocked action is allowed on AWS KMS keys by the managed IAM policy.
Note
To be considered non-public, an IAM policy must grant access only to fixed values. This means values that don't contain a wildcard or the following IAM policy element: Variables.
Note
If a single value in an IAM customer managed policy (for example, one Resource or Condition value) contains more than five IAM policy variables, the rule can't evaluate that policy and returns NON_COMPLIANT, even if the policy would otherwise be compliant. To get an accurate evaluation, split any value that contains more than five policy variables so that each value contains five or fewer.

Parameters:
- blockedActionsPatterns

-
Comma-separated list of blocked KMS action patterns. For example, you can list kms:Decrypt* or kms:ReEncrypt as blocked action patterns. The rule is NON_COMPLIANT if the managed IAM policy allows any action pattern listed in this parameter.
- excludePermissionBoundaryPolicy (Optional)
- Type: boolean
-
Boolean flag to exclude the evaluation of IAM policies used as permissions boundaries. If set to 'true', the rule will not include permissions boundaries in the evaluation. Otherwise, all IAM policies in scope are evaluated when value is set to 'false.' Default value is 'false'.
