Defending against brute force ssh attacks

Filed under Network Security

Found a good article today on how to properly defend against brute force ssh attacks. I knew that iptables was one method to do it but there are many others. Take a look at this article for methods like:

* Strong passwords
* RSA authentication
* Using ‘iptables’ to block the attack
* Using the sshd log to block attacks
* Using tcp_wrappers to block attacks
* Using knockd
