Intrusion Detection & Prevention Systems (IDS/IPS)

Summary

An IDS monitors traffic and alerts on suspicious patterns; an IPS actively blocks it — both rely on signature-based detection (known attack patterns) and/or anomaly-based detection (deviation from normal).

How to Learn This

1Explore an open-source IDS (like Snort or Suricata) and review a sample detection rule.
2Learn the trade-off: IDS observes without blocking, IPS blocks but risks false-positive disruption.
3Understand the difference between signature-based and anomaly-based detection approaches.
