Title: Execute permissions on xp_cmdshell from all users (except dbo) should be revoked.
Description: The xp_cmdshell extended stored procedure spawns a Windows command shell, passing in a string for execution. This rule checks that no users (except users with the CONTROL SERVER permission like members of the sysadmin server role) have permission to execute the xp_cmdshell ext
ended stored procedure.
Rationale: The xp_cmdshell extended stored procedure is a very powerful tool, but because of that, it is crucial that access to xp_cmdshell be tightly controlled. By default, only users with the CONTROL SERVER permission like members of the sysadmin server role can execute this extended
stored procedure. When first enabled, xp_cmdshell has the same security context as the SQL Server service account. The SQL Server service account is often more privileged than necessary for the work being performed by the process created by xp_cmdshell. As such, malicious users can attempt
to elevate their privileges by using xp_cmdshell. See https://learn.microsoft.com/en-us/sql/relational-databases/system-stored-procedures/xp-cmdshell-transact-sql for more information on xp_cmdshell.

Title: Latest updates should be installed
Description: Microsoft periodically releases Cumulative Updates (CUs) for each version of SQL Server. This rule checks whether the latest CU has been installed for the particular version of SQL Server being used.
Rationale: Running with the latest Cumulative Updates (CU) for any particular version of SQL Server is important as these CU are a collection of all available patches up-to-date, including all known security fixes. Microsoft officially recommends ongoing, proactive installation of SQL
Server CUs as they become available.

Title: Minimal set of principals should be members of fixed high impact database roles
Description: SQL Server provides roles to help manage the permissions. Roles are security principals that group other principals. Database-level roles are database-wide in their permission scope. This rule checks that a minimal set of principals are members of the fixed database roles.
Rationale: Fixed database roles may have administrative permissions on the system. Following the principle of least privilege, it is important to minimize membership in fixed database roles and keep a baseline of these memberships. See
https://learn.microsoft.com/en-us/sql/relational-databases/security/authentication-access/database-level-roles for additional information on database roles.
