# iam-customer-policy-blocked-kms-actions
<a name="iam-customer-policy-blocked-kms-actions"></a>

Checks if the managed Amazon Identity and Access Management (IAM) policies that you create do not allow blocked KMS actions on all Amazon KMS key resources. The rule is NON\_COMPLIANT if any blocked action is allowed on all Amazon 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](https://docs.amazonaws.cn/IAM/latest/UserGuide/reference_policies_variables.html#policy-vars-using-variables).

**Identifier:** IAM\_CUSTOMER\_POLICY\_BLOCKED\_KMS\_ACTIONS

**Resource Types:** AWS::IAM::Policy

**Trigger type:** Configuration changes

**Amazon Web Services Region:** All supported Amazon regions except Asia Pacific (New Zealand), Asia Pacific (Thailand), Middle East (UAE), Asia Pacific (Hyderabad), Asia Pacific (Malaysia), Asia Pacific (Melbourne), Mexico (Central), Israel (Tel Aviv), Asia Pacific (Taipei), Canada West (Calgary), Europe (Spain), Europe (Zurich) Region

**Parameters:**

blockedActionsPatternsType: CSV  
Comma-separated list of blocked KMS action patterns for the rule to check. The rule is NON\_COMPLIANT if IAM customer managed policies allow wildcard access to all resources for the actions you specify.

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'.
