| 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 organization's 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.
Data transfer requirements between security domains is not a function of DNS. |
