Title

(CUI) The ENS Firewall must be configured to use FTP protocol inspection. (Cat II impact)

Discussion

(CUI) A host-based firewall scans all incoming and outgoing traffic. As it reviews arriving or departing traffic, the Firewall checks its list of rules, which is a set of criteria with associated actions. If the traffic matches all criteria in a rule, the Firewall acts according to the rule, blocking or allowing traffic through. A host-based firewall adds another layer of protection to prevent unauthorized traffic from reaching or leaving the system. To be effective, it must be enabled and properly configured. Operation across different classification levels or across mixed DoD and non-DoD networks could cause cross-contamination of data, loss of data, data leakage, or unauthorized access. Configuring a CAG/LAG firewall rule will prevent cross-domain traffic.
