Why are all the students put under one user name? That will give access to all students to every folder.

The only thing I can suggest is to ask your system admin to make different user accounts for each student to enhance security and privacy.

Yes. If there is the same account, then the only thing you can do is to put a password to your content, but cannot avoid others to delete your files. Are you sure is the same account? Does anyone have the SAME PASSWORD? Because in that case one user changing the account's password will leave all the others without access.

Maybe you are all in /home/student/, but they are different accounts. In that case you can change the permissions of /home/student/suresh by using the chmod command. Something like

chmod og-rwx /home/student/suresh
will prevent other to read, write and execute the directory. Yet you can use only og-w to prevent modifications, but allow reading.

Hope it helps...

First, all users should have a different name. You can
lump them in the same group. Use the control center
to set them up. On the console, if you know chmod, chgrp,
and chown, you should be able to manipulate everything.
In specific, chmod can used to have read/write/execute
permission for different groups. Learn these commands
via man page.
