Title: Applications must enforce information flow control on metadata.
Vulnerability ID: V-32228
IA Controls: None
Description: Information flow control regulates where information is allowed to travel within an information system and between information systems (as opposed to who is allowed to access the information) and without explicit regard to subsequent accesses to that information.
Information flow enforcement mechanisms compare security attributes on all information (data content and data structure), source and destination objects, and respond appropriately (e.g., block, quarantine, alert administrator) when the mechanisms encounter information flows not explicitly allowed by the information flow policy.
Metadata is defined as data providing information about one or more other pieces of data such as; purpose of the data, author/creator of the data, network location of where data was created, and application specific data information.
This requirement applies only to network devices specifically for handling flow control. This requirement is NA for databases.
Check Text: This check is NA for databases.
Fix Text: This fix is NA for databases.[divider]
As this requirement focuses on network device compliance, it doesn’t really apply to SQL Server. You should still make sure connections used by SQL Server are secure. This means setting up SQL Server to use SSL on connections, to verifying you are aware of what each linked server and endpoint is used for and secured.
