DoD STIGs – V-32218

Overview:

Title: Applications must provide the ability to enforce security policies regarding information on interconnected systems.

Vulnerability ID: V-32218

STIG ID:

IA Controls: None

Severity: medium

Description: The application 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.

Transferring information between interconnected information systems of differing security policies introduces risk that such transfers violate one or more policies. While security policy violations may not be absolutely prohibited, policy guidance from information owners/stewards is implemented at the policy enforcement point between the interconnected systems. Specific architectural solutions are mandated, when required, to reduce the potential for undiscovered vulnerabilities.

Architectural solutions include: (i) prohibiting information transfers between interconnected systems (i.e., implementing access only, one way transfer mechanisms); (ii) employing hardware mechanisms to enforce unitary information flow directions; and (iii) implementing fully tested, re-grading mechanisms to reassign security attributes and associated security labels.

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.
