The IDPS must prohibit the transfer of unsanctioned information in accordance with the security policy when transferring information between different security domains.

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, policy filters must be applied to the data to enforce the organizations security policy requirements. Actions to support this requirement include, but are not limited to: checking packet payload for embedded malware; dropping packets not conforming to standards; and blocking packets using ports and protocols that are not allowed to cross these domains based on DoD and local policy. This requirement applies to 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.
