The casper-files and their vulnerability?

Hi
I am making a bootable live-system out of my Ubuntu 10.04.
The thing i am wondering about is the socalled casper-files.
I have done some changes to /etc/fstab and /etc/network/interfaces after
making the bootable system(on the running system).
The question is, will my changes be reverted if someone inserted "blank"
casper-files
into my system? Really thankful if anyone can explain how this is done.
What exactly does
these casper-files contain, (details probably not needed, just
explanation to help me understand)
Got some help earlier with making some of the casper-bottom scripts not
run at boot time.
How are the casper-files merged with the rest? Is it only scripts, or is
it more to it than that?
The system will maybe be used in school-situations(by students), so
security should be somewhat as good as it gets.
The worrying bit is: Someone steals the system, boots it from another
linux, replaces the casper-files
and gains access to resources that he shouldn`t have during a "exam", is
this possible?
