Vulnerability discussion

Failure to provide logical access restrictions associated with changes to configuration may have significant effects on the overall security of the system. When dealing with access restrictions pertaining to change control, it should be noted that any changes to the hardware, software, and/or firmware components of the information system can potentially have significant effects on the overall security of the system. Accordingly, SQL Server and Windows must allow only qualified and authorized individuals to obtain access to system components for the purposes of initiating changes, including upgrades and modifications.

Check content

Review the security configuration of the SQL Server instance and database(s). If unauthorized Windows users can start the SQL Server Configuration Manager or SQL Server Management Studio, this is a finding. If SQL Server does not enforce access restrictions associated with changes to the configuration of the SQL Server instance or database(s), this is a finding. - - - - - To assist in conducting reviews of permissions, the following views and permissions are defined in the supplemental file Permissions.sql, provided with this STIG: database_permissions database_role_members server_permissions server_role_members database_effective_permissions('') database_roles_of('') members_of_db_role('') members_of_server_role('') server_effective_permissions('') server_roles_of('') Permissions of concern in this respect include the following, and possibly others: - any server permission except CONNECT SQL, but including CONNECT ANY DATABASE - any database permission beginning with "CREATE" or "ALTER" - CONTROL - INSERT, UPDATE, DELETE, EXECUTE on locally-defined tables and procedures designed for supplemental configuration and security purposes.

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
