Suricata is a free, open-source, independent threat detection engine developed by the Open Information Security Foundation. It is a flexible, high-performance intrusion detection system (IDS), intrusion prevention system (IPS), and network security monitoring (NSM) tool that can detect and block attacks against your network. The IDS analyses network traffic and detects known attacks by matching signatures, while the IPS has the ability to stop a packet from being delivered depending on the attack detected.
In this post, we will show you how to install Suricata IDS on Rocky Linux 8.
