Intrusion Detection and Prevention (IDS/IPS) Fundamentals

As network threats evolve, security professionals must know how to monitor traffic and block malicious activity in real-time. This text-based course guides you through the foundational concepts of Intrusion Detection Systems (IDS) and Intrusion Prevention Systems (IPS). You will transition from understanding basic network packets to writing custom detection rules and analyzing traffic logs using industry-standard open-source tools. By studying clear explanations and structured configuration examples, you will build the practical confidence needed to secure modern network environments. What you'll learn: - Understand the core differences between signature-based and anomaly-based detection. - Write and test custom detection rules for Snort and Suricata to identify malicious traffic patterns. - Analyze network behavior and extract rich metadata using Zeek. - Deploy and configure IDS/IPS engines within a modern network architecture. - Interpret alerts and logs to identify common attack vectors and false positives. - Integrate detection telemetry with broader security monitoring and modern observability workflows. Starting with essential network security terminology and architecture, this course guides you step-by-step through configuring Snort, Suricata, and Zeek, concluding with practical rule-writing and traffic analysis exercises. It is designed for beginners in cybersecurity, network administration, or systems engineering, with no prior IDS/IPS experience required.
