GIAC GCED Exam - Topic 7 Question 57 Discussion

Actual exam question for GIAC's GCED exam

Question #: 57
Topic #: 7

A security device processes the first packet from 10.62.34.12 destined to 10.23.10.7 and recognizes a malicious anomaly. The first packet makes it to 10.23.10.7 before the security devices sends a TCP RST to 10.62.34.12. What type of security device is this?

AHost IDS

BActive response

CIntrusion prevention

DNetwork access control

Pretty sure it's not Network access control.

Wait, how can it send a TCP RST after the packet gets through?

I thought it was just a Host IDS?

Definitely an active response!

Sounds like an Intrusion prevention system to me.

I feel like this is definitely related to intrusion prevention, but I could see how it might also be interpreted as active response.

I’m a bit confused. Is it possible for a host IDS to send a TCP RST? I thought they just monitored traffic.

This sounds like a question we practiced in class! I think it might be an active response since it sends a TCP RST.

I remember studying about intrusion prevention systems, but I'm not sure if that's the right answer here.

This has got to be an intrusion prevention system (IPS). The key giveaway is the security device actively sending the TCP RST to the source IP to block the traffic after detecting a malicious anomaly. That's the textbook behavior of an IPS.

I'm a little confused by this question. The details about the security device's actions don't seem to fully match the answer choices provided. I'll need to review my notes on the different types of security devices to figure out the best answer here.

Okay, I've got this. The security device is clearly an IPS since it actively blocked the traffic by sending the TCP RST. The fact that the first packet got through is just because of the way IPS systems work - they detect and respond to threats in real-time.

Hmm, I'm a bit unsure about this one. The fact that the first packet still made it to the destination before the security device responded makes me think it could also be a host-based IDS. I'll need to think this through a bit more.

This seems like a classic intrusion prevention system (IPS) scenario. The key details are the security device detecting a malicious anomaly and then sending a TCP RST to the source, which indicates an active response to block the traffic.

As a security professional, I'm impressed by this device's quick reflexes. But as a cat owner, I'm a little worried it might start randomly batting at my internet packets just for fun.

Network access control? Nah, this is way more advanced than that. This is a security device that can see into the packets, analyze them, and respond in real-time. I'm putting my money on Intrusion Prevention System.

I'm going with C, Intrusion Prevention System. The fact that it recognized the anomaly and took immediate action to stop the attack, but still let the first packet through, is a dead giveaway.

Active response, for sure! Blocking the malicious traffic and sending a reset to the source is a classic active defense move. I bet the security team high-fived each other after that one.

Hmm, this seems like an intrusion prevention system (IPS) to me. It detected the malicious anomaly and sent a TCP RST to the source, but the first packet still made it to the destination. Gotta love those lightning-fast response times!
