Messy, a network defender, was hired to secure an organization's internal network. He deployed an IDS in which the detection process depends on observing and comparing the observed events with the normal behavior and then detecting any deviation from it.
Identify the type of IDS employed by Messy in the above scenario.

Sounds a bit off to me. How do we know it’s not application proxy?

Wait, are we sure it’s not stateful protocol analysis?

Agreed, anomaly-based is the right choice here.

I think it’s signature-based, though.

Definitely anomaly-based! It looks for deviations.

I could be wrong, but I feel like signature-based IDS focuses more on known threats rather than behavior deviations.

This sounds similar to a practice question I did on IDS types, and I believe the answer is anomaly-based too.

I'm not entirely sure, but I remember something about stateful protocol analysis being related to tracking sessions.

I think this is about anomaly-based IDS since it mentions detecting deviations from normal behavior.

I've got this one! The key is the part about comparing the observed events to normal behavior and detecting deviations. That's the textbook definition of an Anomaly-based IDS. I'm confident that's the right answer.

Hmm, I'm a bit confused here. The question talks about observing events and comparing them to normal behavior, but it doesn't explicitly say it's an anomaly-based IDS. I'm not sure if that's the right answer.

This one seems pretty straightforward. The question mentions the IDS detecting deviations from normal behavior, so I'm going to go with option B, Anomaly-based.

Okay, let me think this through. The IDS is detecting deviations from normal behavior, so that rules out signature-based and application proxy. I think Anomaly-based is the best fit here, but I'll double-check the definitions just to be sure.

B) Anomaly-based is the way to go. Messy's clearly a pro at this, and that's the only option that matches the description. Now, if only he could do something about that name...

Application proxy IDS may not be the best fit for this scenario, anomaly-based is the way to go.

Signature-based IDS may not be as effective in detecting new or unknown threats.

Messy must have a good understanding of network security to choose anomaly-based IDS.

I agree, anomaly-based is the best choice for detecting deviations from normal behavior.

The question is a bit too straightforward, don't you think? I'm going to go with D) Application proxy just to keep things interesting. Who knows, maybe Messy has a few tricks up his sleeve!

I agree with you, I'll go with B) Anomaly-based. It's always good to mix things up in network security.

I'm leaning towards A) Stateful protocol analysis. It's a solid option for detecting deviations in network traffic.
MA

I think it's C) Signature-based. That's a common choice for network defenders.
NA

Hmm, this one's a bit tricky. I'm torn between B) Anomaly-based and C) Signature-based. But I'll go with B since Messy seems to be a pretty savvy network defender.

User1: Definitely, it's all about spotting those anomalies to keep the network secure.

User2: Yeah, that makes sense. Anomaly-based IDS would be a good choice for detecting deviations from normal behavior.

User1: I think it's B) Anomaly-based too. Messy probably wants to catch any unusual behavior.
RE

I think the answer is B) Anomaly-based. The scenario describes an IDS that compares observed events with normal behavior to detect deviations, which is the hallmark of an anomaly-based IDS.
VE
Vernice

Yes, anomaly-based IDS is the correct choice in this scenario.

I agree, the description fits an anomaly-based IDS.

I agree with Mireya, signature-based makes more sense in this scenario as it detects deviations from known patterns.
MI
Mireya

I disagree, I believe it is signature-based because it compares observed events with known patterns.
