Control: 1.3 Ensure credentials unused for 90 days or greater are disabled

Description

AWS IAM users can access AWS resources using different types of credentials, such as passwords or access keys. It is recommended that all credentials that have been unused in 90 or greater days be removed or deactivated.

Disabling or removing unnecessary credentials will reduce the window of opportunity for credentials associated with a compromised or abandoned account to be used.

1. Login to the AWS Management Console:
2. Click Services.
3. Click IAM.
4. Click on Users.
5. Click on Security Credentials.
6. As an Administrator.

• Click on Make Inactive for credentials that have not been used in 90 Days.

7. As an IAM User.

• Click on Make Inactive or Delete for credentials which have not been used in 90 Days.
