This rule checks whether "Password expiration" of each SQL Server login is enabled. If SQL Server Authentication is enabled and if the operating system version is earlier than Windows Server 2003, an attacker could repeatedly exploit a known SQL Server login password.
Best Practices Recommendations
We recommend that you upgrade the operating system to Windows Server 2003.
If SQL Server Authentication is not required in your environment, use Windows Authentication. For more information, see Choose an Authentication Mode.
Enable "Password expiration" for all the SQL Server logins. Use ALTER LOGIN to configure the password policy for the SQL Server login.
