How to Disable Root SSH Login on Linux

Open ssh config file # vim /etc/ssh/sshd_config
#PermitRootLogin yes

Replace this line by:
 PermitRootLogin no

In this file we can also change the "Port number" and "Banner" details as well and much more.

# service sshd restart

after when we login as "root" user it will show "Access denied" message.

Now login as a normal user and switch as root.
