In AWS Identity and Access Management (IAM), a password policy is a set of rules that define the complexity requirements for IAM user passwords. One of the password policy requirements is that the password must contain at least one lowercase letter. By enforcing a strong password policy that requires the use of lowercase letters, IAM users are encouraged to use passwords that are more difficult to guess or crack, which can help improve the overall security of AWS resources and data. Additionally, IAM users are prompted to change their passwords periodically, further improving the security of their accounts.‍


The following are the remediation steps to ensure that the IAM password policy requires at least one lowercase letter:

  1. Log in to the AWS Management Console as an IAM user with administrator privileges.
  2. Navigate to the IAM dashboard and select "Account settings."
  3. In the "Account settings" page, locate the "Password policy" section and click the "Edit" button.
  4. In the "Edit password policy" dialog box, ensure that the "Require at least one lowercase letter" option is selected.
  5. Optionally, you can also configure other password policy settings such as requiring the use of uppercase letters, numbers, and symbols.
  6. Click the "Save changes" button to save the updated password policy.
  7. Test the new password policy by creating a new IAM user and setting a password that includes at least one lowercase letter.
  8. Verify that the new password policy is in effect for all IAM users by checking the IAM console and ensuring that all user passwords include at least one lowercase letter.

By following these steps, you can ensure that the IAM password policy requires the use of at least one lowercase letter in user passwords, helping to improve the security of AWS resources and data. Additionally, you can configure other password policy settings to further enhance the security of IAM user passwords.
