How To Protect SSH with Fail2Ban: A Beginner’s Guide

Dive into our beginner’s guide on securing SSH with Fail2Ban to safeguard your server from unauthorized access and brute-force attacks.

We will start with a metaphor. Imagine a fortress; while its tall walls and strong gates are built to keep out unwanted visitors, there will always be those who attempt to scale the walls or force the gates. 

Similarly, our digital fortress, especially servers, faces persistent threats. One such gate to it is the Secure Shell (SSH), a protocol allowing secure remote access. So, just as gates require guards and monitoring systems, SSH requires protective measures against potential intruders.

Enter Fail2Ban – a vigilant sentry for your servers. It is one of the most effective shields against unauthorized access attempts, especially brute force.
