Title

(CUI) The ENS Firewall must be enabled with intrusion alerts. (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.
