I recall a practice question where we discussed the differences, and I think C is definitely the right answer for behavior-based detection.

I keep mixing up the different detection methods. I thought pattern matching was behavior-based too, but now I'm confused.

I feel like we covered this in class, and I think statistical anomaly detection is the one that fits behavior-based IDS.

I think I remember that behavior-based methods focus on detecting anomalies, so maybe it's C? But I'm not entirely sure.
