Description

Information flow control regulates where information is allowed to travel within an information system and between information systems (as opposed to who is allowed to access the information) and without explicit regard to subsequent accesses to the information. 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 and between interconnected systems. Flow control is based on the characteristics of the information and/or the information path.

Check Text ( C-53747r1_chk )
Ask the SA or IAO if an approved firewall is loaded on the system. The recommended system is the McAfee HBSS. If there is no local firewall installed on the system, and configured with a default deny policy, this is a finding.

Fix Text (F-56209r1_fix)
Install an approved HBSS or firewall solution onto the system.
