DoD STIGs – V-32220


Title: Applications must uniquely authenticate source domains for information transfer.

Vulnerability ID: V-32220


IA Controls: None

Severity: medium

Description: The information system enforces approved authorizations for controlling the flow of information within the system and between interconnected systems in accordance with applicable policy.

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.

Specific examples of flow control enforcement can be found in boundary protection devices (e.g., proxies, gateways, guards, encrypted tunnels, firewalls, and routers) employing rule sets or establish configuration settings restricting information system services, provide a packet-filtering capability based on header information, or message-filtering capability based on content (e.g., using key word searches or document characteristics).

Attribution, (e.g., the ability to attribute actions to certain individuals) is a critical component of a security concept of operations. The ability to identify source and destination points for information flowing in an information system, allows forensic reconstruction of events when required, and increases policy compliance by attributing policy violations to specific organizations/individuals.

This requirement is specific to network devices designed to perform information 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-V-32220:

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.
