Using Screenlock
Rationale
Leaving a screen unlocked enables attackers to access the system with the logged-in user's privileges. Manually or automatically locking the screen with a password helps prevent unauthorized access.
Instructions for Enabling Manual and Automatic Locking
By default, there is no way for the user to manually lock the screen. To enable manual and automatic screen locking, follow these steps:
In Setup, go to User Interface > Screenlock / Screensaver > Options.
Activate the Screenlock Session.
Activate the Quick Start Panel starting method to provide a manual lock button to the user.
Activate Password Protection and set it to User.
Activate Hotkey Configuration and assign a key combination to lock the screen manually (e.g., [Ctrl|Shift+L]).
Go to the Options section.
Activate Start automatically.
(Optional) Adjust the Timeout to the desired idle time (in minutes).
Click Save.
