The IDPS must detect unsanctioned information when transferring information between different security domains.

Overview

Finding ID	Version	Rule ID	IA Controls	Severity

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. It is imperative that when information is being moved from one security domain to another, mechanisms are deployed to detect traffic with payloads that are not in conformance with the policy of the DoD and the organization. This requirement applies to information flow control for Cross Domain Solutions. Implementation and placement of the IDS and IDP sensors and components must not be designed to require information transfer across security domains that differ in classification. There is a high risk of contamination because of the monitoring functionality of the sensors.
