Episode 99 — IDS vs IPS: detection versus prevention and tuning tradeoffs
IDS and IPS decisions appear in CloudNetX scenarios because teams must balance visibility, prevention, and operational stability, and the exam expects you to recognize when blocking is appropriate and when it is too risky. This episode defines an IDS as a detection system that monitors traffic and raises alerts without blocking, and an IPS as a prevention system that blocks traffic based on signatures or behavioral rules. The first paragraph focuses on the strategic difference: IDS provides safer visibility when false positives would disrupt business, while IPS provides stronger protection when prevention outweighs disruption risk. It explains how placement matters, because inline IPS can introduce latency and becomes a dependency for traffic flow, and it frames tuning as a required step because raw signatures produce noise that can lead to ignored alerts or accidental outages if blocking is enabled prematurely.
