controls::sql servers mssql service account is not an administrator

Overview

The service account and/or service SID used by the MSSQLSERVER service for a default instance or service for a named instance should not be a member of the Windows Administrator group either directly or indirectly (via a group). This also means that the account known as LocalSystem (aka NT AUTHORITY\SYSTEM) should not be used for the MSSQL service as this account has higher privileges than the SQL Server service requires.

Following the principle of least privilege, the service account should have no more privileges than required to do its job. For SQL Server services, the SQL Server Setup will assign the required permissions directly to the service SID. No additional permissions or privileges should be necessary.

Skipping

To deliberately skip this control (e.g. meaning don’t use Puppet to enforce this setting), we provide you with three ways:

1) Add mssql_secured::controls::sql_servers_mssql_service_account_is_not_an_administrator: skip to your hiera data. This will skip this control for ALL databases.
2) Add mssql_secured::controls::sql_servers_mssql_service_account_is_not_an_administrator::dbname: skip to your hiera data. This will skip this control for specified database only.
3) Add an entry with the content sql_servers_mssql_service_account_is_not_an_administrator to the array value mssql_secured::skip_list in your hiera data.
