Leaving a screen unlocked enables attackers to access the system with the logged-in user's privileges. Manual or automatic locking the screen with a password prevents such access.
Instructions for Enabling Manual Locking
By default, there is no way for the user to manually lock the screen. To enable manual locking, follow these steps:
In IGEL Setup go to User Interface > Screenlock / Screensaver
Do one or both of the following:
Activate the Quickstart panel starting method to give the user a button for locking the screen manually.
Activate Use hotkey and set a combination of keys that lets the user lock the screen manually, e.g. [Ctrl-Shift-L].
Click Apply.
Instructions for Automatic Locking
By default, the screensaver is started automatically after 5 minutes, but the screen is not locked with a password. To enable locking, follow these instructions:
Go to User Interface > Screenlock / Screensaver > Options.
Activate Start automatically.
Set the Timeout, i.e. the number of minutes of user inactivity before the screensaver starts automatically. (Default: 5)
As a password select User password (see Setting Local Passwords) or a separate Screenlock password (and set one). (Default: none)
Optionally, check Allow administrator password to allow the administrator to unlock a user's screen. (Default: enabled)
