Ensure a Login Window Banner Exists

보통레벨 2자동macos

설명

A Login window banner warning informs the user that the system is reserved for authorized use only. It enforces an acknowledgment by the user that they have been informed of the use policy in the banner if required. The system recognizes either the .txt and the .rtf formats. Audit: A /Library/Security/PolicyBanner.* file must exist and its mode must have 4 as the third digit.
