Ensure 'CHECK_EXPIRATION' Option is set to 'ON' for All SQL Authenticated Logins Within the Sysadmin Role

中レベル 1自動mssql

説明

Applies the same password expiration policy used in Windows to passwords used inside SQL Server. Ensuring SQL logins comply with the secure password policy applied by the Windows Server Benchmark will ensure the passwords for SQL logins with sysadmin privileges are changed on a frequent basis to help prevent compromise via a brute force attack. CONTROL SERVER is an equivalent permission to sysadmin and logins with that permission should also be required to have expiring passwords.
