SQL Server must maintain and support organization-defined security labels on stored information.

Description
Security attributes are abstractions representing the basic properties or characteristics of an entity (e.g., subjects and objects) with respect to safeguarding information. These attributes are typically associated with internal data structures (e.g., records, buffers, files) within the information system and are used to enable the implementation of access control and flow control policies; reflect special dissemination, handling, or distribution instructions; or support other aspects of the information security policy. One example includes marking data as classified or FOUO. These security attributes may be assigned manually or during data processing but, either way, it is imperative these assignments are maintained while the data is in storage. If the security attributes are lost when the data is stored, there is the risk of a data compromise. The sensitivity marking or labeling of stored data items promotes the correct handling and protection of data. Without such notification, the user may unwittingly disclose sensitive data to unauthorized users.

Check Text ( C-47925r2_chk )
Review system documentation to determine if the labeling of sensitive data is required under organization-defined guidelines. If the labeling of sensitive data is not required, this is NA. Obtain system configuration settings to determine how data labeling is being performed. This can be through triggers or some other SQL-developed means or via a third-party tool. Spot check data and ensure the appropriate labels have been applied to stored data. If the labeling of sensitive data is required and is not being performed, this is a finding.

Fix Text (F-46813r2_fix)
Develop SQL code or acquire a third-party tool to perform data labeling. SQL Server Label Security Toolkit 2.0 can be downloaded from http://sqlserverlst.codeplex.com/releases/view/83460. This tool can satisfy all data labeling and security data labeling requirements.
