Ensure Firewall Is Enabled

높음레벨 1자동macos

설명

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. Prior to macOS 15.0 Sequoia, there were additional steps to turn on firewall logging after enabling the firewall. As of macOS 15, logging is turned on automatically without user interaction. The logging recommendation has been removed in the macOS 15 benchmark and will not be included going forward. If your organization is looking for more detailed information about network security, you will need a third-party solution. A firewall minimizes the threat of unauthorized users gaining access to your system while connected to a network or the Internet.
