The Linutop OS offers a security system bound to its internal architecture. It uses the concept of LiveCD, but makes it more flexible.
The system is contained in a single file that can't be modified. No matter what happens on the system, you'll always be able to restore the original state of the system using this file.
By default the Linutop OS behaves like any system. Anything you do is written on disk and will still be there after a reboot. Administration tasks will require a master password.
Switching the system in Lock mode will make all new changes temporary. After having configured the system to your needs, switching to this mode will allow to discard all new changes on reboot. You'll always find the same start at startup.
The choice of the security level can be done in the Linutop Configuration Panel, . Check the box to enable high security.
The Lock mode offers additional options:
the admin password can be changed (button)
security options can be added/removed (button):
To switch back to normal mode, you'll have to execute the Linutop Configuration Panel and uncheck the in the tab.
If you've disable the startup menu and the desktop icons, you can use the Ctrl+Alt+s shortcut.
