Network intrusion detection alerts you to suspicious traffic within your network that may indicate a security breach, policy violation, or insecure software. Suricata is a popular opensource network intrusion detection system (NIDS) that can also be used for network intrusion prevention (NIPS) and is used in a number of commercial cybersecurity products.
In this video I'll show you how to install Suricata on Ubuntu or Rocky Linux*, perform basic configuration, and tweak the rulesets to successfully identify malicious activity whilst minimising false positive alerts.

*Rocky's instructions also appply to AlmaLinux, Red Hat Enterprise Linux, Oracle Linux, and CentOS.
