Ensure an Inactivity Interval of 15 Minutes Or Less for the Screen Saver Is Enabled

中等級 1自動化macos

說明

A locking screen saver is one of the standard security controls to limit access to a computer and the current user's session when the computer is temporarily unused or unattended. In macOS, the screen saver starts after a value is selected in the drop- down menu. 15 minutes or less is an acceptable value. Any value can be selected through the command line or script, but a number that is not reflected in the GUI can be problematic. 15 minutes is the default for new accounts. Setting an inactivity interval for the screen saver prevents unauthorized persons from viewing a system left unattended for an extensive period of time.
