I have made a new user (operator group), and a shell task that ask for the GELI password and fsck and mount the USB disk. This work fine under root. but I think that if he/she want to make CTRL-C to the shell task, he can stop the task and then enter in the system and look whatever he wants (for example, how the things are done). How can I stop him from entering this CTRL-C (and others than could be) ? I want this because there is intelectual propierty behind this. Thanks in advance Juan Coruņa Desarrollo de Software Atlantico
