That comes under something called physical security. You can do
1. Set bios password But still, its not secure. because, if the person can open the cabinet and reset the CMOS, then no use 2. Force linux to ask single user password Still not secure. If the person can put a live cd and mount your hard disk and edit the shadow file in the disk. Physical security is something that operating system cannot handle. bottom line There is nothing called 100% secure system. You can achieve that by putting your system in a bank locker after shutting it down. Even then I am not sure, if that bank locker is 100% secure ;-) On Fri, Jul 1, 2011 at 7:13 PM, aravind vijayan <aravindvijayan224...@gmail.com> wrote: > Hi all, > Please visit this link: > http://www.debuntu.org/recover-root-password-single-user-mode-and-grub > > it tells about resetting root and other user passwords then What is the > scope of linux security ... > Aravind vijayan > Elayidathukunnel > > > _______________________________________________ > Indian Libre User Group Cochin Mailing List > http://www.ilug-cochin.org/mailing-list/ > http://mail.ilug-cochin.org/mailman/listinfo/mailinglist_ilug-cochin.org > #ilugko...@irc.freenode.net > -- Regards, Unni http://mutexes.org/ http://twitter.com/webofunni http://sourceforge.net/projects/imdbmoviefetche/ _______________________________________________ Indian Libre User Group Cochin Mailing List http://www.ilug-cochin.org/mailing-list/ http://mail.ilug-cochin.org/mailman/listinfo/mailinglist_ilug-cochin.org #ilugko...@irc.freenode.net
