APPL-26-000003 - The macOS system must enforce session lock no more than five seconds after screen saver is started.

Information

A screen saver must be enabled and the system must be configured to require a password to unlock once the screen saver has been on for a maximum of five seconds.

An unattended system with an excessive grace period is vulnerable to a malicious user.

Solution

Configure the macOS system to initiate a session lock within five seconds of the screen saver starting by installing the "com.apple.screensaver" configuration profile.
