You can disable Shell access but it is not a good idea at all. What we usually do is RESTRICT SSH access to some accounts. You can use the following command to avoid access via SSH for a given user account.

Code: Select all

# chsh -s /sbin/nologin {username}

The common problem that users expereince is hacking the root account using brute force attacks over SSH. The solution is to disable root access to SSH and make a user and set it to access SSH. See How to secure your system from hacking over SSH.
