I heard that the most common way for a linux machine to be hacked is through SSH/SSHD. How can I secure my SSH using keys?
1. Change your default SSH Port
2. Generate a SSH keygen: http://linuxproblem.org/art_9.html
3. Disable Password authorization(Warning, First generate a keygen, If you can't connect to SSH then don't try to disable password authorization)
Now, Restart sshd
4. You can also find some tutorials on google
