Hello,
looks like physical access to Linux machine ( or UNIX in wider sense )
presents clear danger since simple "chrooting" into operating system
makes changing or blanking root password possible. Few months ago I
obtained Sun Enterprise 3500 server with Solaris on it and I wanted to
see how system on such machine works so I simply booted with Solaris CD
and and just blanked password from /etc/shadow manually. It was so easy,
but in the same time, such easy possibility of access to root password
worries me.
My question is: is there any known method to prevent this on Linux or
any kind of Unix system ?
Thanks,
Tomislav
Physical access to any computer results in total compromise. There is,
for example, a Linux Live CD that will permit you to change the admin
password on an MS machine.
