Hey guys, just curious as of how many of you actually harden your server?
I have to admit I'm pretty lacking when it comes to securing my server, I use to install CSF with Webmin but lately I just disable password based logins to SSH and use Private Keys for authentication, that's about all..
In recent light of all the vulnerabilities, I'm interested in tightening up security for my server, it would be nice to know what most of you do to secure your server..
