What is an IPS?
Intrusion Prevention System is short-term as IPS, it networks security measures to examine the incoming traffic to perform intrusion detection and then block the detected incidents. For example, IPS can drop malicious packets, ban the traffic coming from an offending IP address.
Introduction to fail2ban
Fail2ban scans log files (e.g. /var/log/apache/error_log) and ban IPs that show the malicious signs — too many password failures, seeking for exploits, etc. Generally, Fail2Ban is then used to update firewall rules to reject the IP addresses for a specified amount of time.
In this article, I will discuss how to prevent your running services against brute force attack using fail2ban.
