Verify the macOS system is configured to initiate a session lock within five seconds of the screen saver starting with the following command:

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

askForPasswordDelay = 5;

If there is no result, or if "askForPasswordDelay" is not set to "5" or less, this is a finding.
