If you use SSH Logins you can lock down the Console to a restriced shell with less enabled commands!
- Login as root User on the Server
- install rbash with:
apt-get install rbash
- rename bash by:
mv /bin/bash /bin/oldbash chmod o= /bin/oldbash
- create a symlink for rbash to bash
$ln -s /bin/bash /bin/rbash
3. enable rbash by system setting /etc/shells
$echo '/bin/rbash' >> /etc/shells
4. set user shell to /bin/rbash
$chsh #set user shell to /bin/rbash
5. Disable "chsh" command for users
$chmod o= /bin/chsh
6. Login as user and test linux commands..
