Title

(CUI) The ENS Firewall Status Control setting must be configured to prevent users from disabling Firewall from system tray. (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. Allowing an end user to disable the Firewall from the system tray introduces vulnerabilities.
