Anomaly-based? Really? I didn't know that!

Wait, are we sure it's not A? Signature-based seems similar.

I’m a bit confused; I thought signature-based was more about known threats rather than monitoring against a baseline.

I practiced a similar question, and I believe anomaly-based is correct because it detects unusual patterns compared to normal behavior.

I'm not entirely sure, but I remember something about network-based systems being more about traffic analysis rather than baselines.

I think the answer might be D, anomaly-based, since it focuses on deviations from a baseline.

I've got a good handle on IDS concepts, so I'm confident the answer is D. Anomaly-based IDS monitors network traffic and compares it to a baseline to detect unusual activity.

I'm a bit confused on the differences between the IDS types. I'll have to review my notes to make sure I understand this properly before answering.

Okay, let me see. Signature-based IDS looks for known attack patterns, network-based IDS monitors the network, and file-based IDS checks file integrity. So I'm pretty sure the answer is D - Anomaly-based IDS.

Can't we just use a network-based IDS to monitor the network traffic and then send the intruders a strongly worded email? That's how I handle all my cybersecurity problems.

Wait, what? Comparing network traffic to a baseline? That sounds like a lot of work. I just want to get this exam over with. Maybe I'll just go with the most tech-sounding option, anomaly-based. That's gotta be it, right?

Okay, let's think this through. Signature-based and file-based don't really fit the description, so I'm gonna go with either network-based or anomaly-based.
