Vulnerability Discussion

Users must be prompted to enter their passwords when unlocking the screen saver. The screen saver acts as a session lock and prevents unauthorized users from accessing the current user's account.

Check

Verify the macOS system is configured to prevent Apple Watch from terminating a session lock with the following command:

/usr/sbin/system_profiler SPConfigurationProfileDataType | /usr/bin/grep "allowAutoUnlock"

allowAutoUnlock = 0;

If there is no result or "allowAutoUnlock" is not set to "0", this is a finding.

Fix

Configure the macOS system to prevent Apple Watch from terminating a session lock by installing the "Restrictions Policy" configuration profile.
