Using IPtables to Stop SSH Brute Force Attacks. I like to think of this approach similar to flow rates with pipes. Bigger pipes allow more water to flow. Smaller pipes can handle less water. To block a SSH brute force attack, we just need to slow down the flow of requests. We can do this by rate-limiting requests to SSH with iptables. Essentially, we create a smaller pipe for new SSH sessions. This slows brute force attacks to a point where they become ineffective.
