Information

Information flow control regulates where information is allowed to travel within a network. 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.
Information flow control policies and enforcement mechanisms are commonly employed by organizations to control the flow of information between designated sources and destinations (e.g., networks, individuals, devices) within information systems. Examples of information flow control restrictions include keeping export-controlled information from being transmitted in the clear to the Internet or blocking information marked as classified that is being transported to an unapproved destination.
ALGs enforce approved authorizations by employing security policy and/or rules that restrict information system services or provide packet filtering capability based on header or protocol information and/or message filtering capability based on data content (e.g., implementing keyword searches or using document characteristics)
NOTE: Nessus has provided the target output to assist in reviewing the benchmark to ensure target compliance.
