Ensure Internet Sharing Is Disabled

높음레벨 1자동macos

설명

Internet Sharing uses the open source natd process to share an internet connection with other computers and devices on a local network. This allows the Mac to function as a router and share the connection to other, possibly unauthorized, devices. Disabling Internet Sharing reduces the remote attack surface of the system.
