By default, the SSH configuration allows any user with an account to access the system. In order to specify the users that are allowed to login via SSH and deny all other users, add or correct the following line in the '/etc/ssh/sshd_config' file: 'DenyUsers USER1 USER2' Where 'USER1' and 'USER2' are valid user names.


Parameter:

[Deny_Users]


Technical Mechanism:

Specifying which accounts are allowed SSH access into the system reduces the possibility of unauthorized access to the system.
