Ensure Internet Sharing Is Disabled
Description
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. Audit: Passes when com.apple.nat has no "Enabled = 1" entry or a profile sets forceInternetSharingOff.
