### Description{% #description %}

IAM access keys must be rotated regularly to reduce the risk from long-lived credentials and limit the exposure window if a key is compromised. Ensure an `AWS::Config::ConfigRule` resource exists with `Source.SourceIdentifier` set to `ACCESS_KEYS_ROTATED` and that its `InputParameters` contain a `maxAccessKeyAge` value less than or equal to `90` (days). Resources missing this ConfigRule, missing `InputParameters`, or with `maxAccessKeyAge` > `90` will be flagged; `maxAccessKeyAge` is evaluated numerically and is often provided as a string.

Secure configuration example (CloudFormation):

```yaml
AccessKeyRotationRule:
  Type: AWS::Config::ConfigRule
  Properties:
    ConfigRuleName: enforce-access-key-rotation
    Source:
      Owner: AWS
      SourceIdentifier: ACCESS_KEYS_ROTATED
    InputParameters: '{"maxAccessKeyAge":"90"}'
```

## Compliant Code Examples{% #compliant-code-examples %}

```yaml
Resources:
  ConfigRule:
    Type: AWS::Config::ConfigRule
    Properties:
      ConfigRuleName: access-keys-rotated
      InputParameters:
        maxAccessKeyAge: 90
      Source:
        Owner: AWS
        SourceIdentifier: ACCESS_KEYS_ROTATED
      MaximumExecutionFrequency: TwentyFour_Hours
```

```json

  "Resources": {
    "ConfigRule": {
      "Type": "AWS::Config::ConfigRule",
