Vulnerability V-213914

Determine elements of security functionality (lists of permissions, additional authentication information, stored procedures, application specific auditing, etc.) that are being housed inside SQL server. For any elements found, check SQL Server to determine if these objects or code implementing security functionality are located in a separate security domain, such as a separate database, schema, or table created specifically for security functionality. If the database is a SQL Server default database (master, msdb, model, tempdb), this is NA. Run the following query to list all the user-defined databases: SELECT Name FROM sys.databases WHERE database_id > 4 ORDER BY 1; Review the database structure to determine where security related functionality is stored. If security-related database objects or code are not kept separate, this is a finding.

Check the server documentation, locate security-related database objects and code in a separate database, schema, table, or other separate security domain from database objects and code implementing application logic. Microsoft SQL Server 2005 introduced the concept of database object schemas. Schemas are analogous to separate namespaces or containers used to store database objects. Security permissions apply to schemas, making them an important tool for separating and protecting database objects based on access rights. Schemas reduce the work required, and improve the flexibility, for security-related administration of a database. User-schema separation allows for more flexibility in managing database object permissions. A schema is a named container for database objects, which allows the user to group objects into separate namespaces. Where possible, locate security-related database objects and code in a separate database, schema, or other separate security domain from database objects and code implementing application logic. In all cases, use GRANT, REVOKE, DENY, ALTER ROLE … ADD MEMBER … and/or ALTER ROLE …. DROP MEMBER statements to add and remove permissions on server-level and database-level security-related objects to provide effective isolation.
