Ensure Firewall Is Enabled

高级别 1自动化macos

说明

A firewall is a piece of software that blocks unwanted incoming connections to a system. The socketfilter Firewall is what is used when the Firewall is turned on in the Security & Privacy Preference Pane. Logging is required to appropriately monitor what access is allowed and denied. The logs can be viewed in the macOS Unified Logs. Audit: Passes when the com.apple.security.firewall EnableFirewall key is true or socketfilterfw reports State = 1 or 2.
