Episode 95: IPS and IDS Devices — Detecting and Stopping Attacks
Intrusion detection and prevention systems are vital for securing the network against both known and emerging threats. In this episode, we explain the difference between IDS (which monitors and alerts) and IPS (which actively blocks malicious traffic). You'll learn how these devices analyze traffic using signature-based detection, anomaly detection, and heuristics. We discuss inline vs. passive deployment and what role these systems play in a layered defense strategy.
We also cover common placement strategies—whether at the perimeter, on internal segments, or between VLANs—and how these systems integrate with SIEM platforms for centralized alerting. False positives, tuning, and log review are all part of effective deployment and response. Understanding IDS/IPS functionality is key to both exam readiness and real-world security operations.
