The router must enforce information flow control using explicit security attributes (for example, IP addresses, port numbers, protocol, Autonomous System, or interface) on information, source, and destination objects.

Description

Information flow control regulates where information is allowed to travel within a network and between interconnected networks. The flow of all network traffic must be monitored and controlled so it does not introduce any unacceptable risk to the network infrastructure or data. Restrictions can be enforced based on source and destination IP addresses, autonomous system numbers, or other attributes. This is normally an innate capability of a router in which attributes can be used by routing policies or rules to enforce organizational security policies.

If explicit security attributes (for example, IP addresses, port numbers, protocol, Autonomous System, or interface) are not used to enforce information flow control, this is a finding.

Fix Text (F-60623r2_fix)
Configure the router to enforce organizational security policies by using explicit security attributes (for example, IP addresses, Autonomous System, or interface) on information, source, and destination objects as a basis for flow control decisions.
