DoD STIGs – V-32229

Overview:

Title: Applications must use security policy filters as a basis for making information flow control decisions.

Vulnerability ID: V-32229

STIG ID:

IA Controls: None

Severity: medium

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 not explicitly allowed by the information flow policy.

Security policy filters are defined by the organization and include dirty word filters, file type checking filters, structured data filters, unstructured data filters, metadata content filters, and hidden content filters.

– Structured data typically describes data intended for storage in a data management system such as a relational database.
– Unstructured data refers to masses of digital information that do not have a data structure such as word processing documents, email, pictures, audio, and video.
– In the case of unstructured data, metadata is considered to be data about the data in question.
– In the case of structured data, metadata is considered to be data about the containers of the data.

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.

Interpreting V-32229:

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.
