Dive into the critical perimeter and internal network defenses. The IDS/IPS Fundamentals module breaks down how network sensors inspect packet payloads, detect malicious signatures, and block threats in real-time.

You will learn the architectural differences between passive IDS and inline IPS, master the complex syntax of Snort and Suricata rules, understand the power of stateful inspection, and tune network alerts to drastically reduce false positives without sacrificing security. By the end of this module, you will be able to deploy, analyze, and optimize network sensors to catch threats that bypass endpoint defenses.
