Ensure Screen Saver Hot Corners Are Secure For Current User

低レベル 1自動macos

説明

Hot Corners can be configured to disable the screen saver by moving the mouse cursor to a corner of the screen. This can only be accomplished by the current user, so that is the only user that needs to be audited. Audit: Checks the console user (or loginwindow lastUserName); no corner may be set to 6 (Disable Screen Saver).
