GAQM CPEH-001 Exam - Topic 5 Question 56 Discussion

Actual exam question for GAQM's CPEH-001 exam
Question #: 56
Topic #: 5
[All CPEH-001 Questions]

StackGuard (as used by Immunix), ssp/ProPolice (as used by OpenBSD), and Microsoft's /GS option use _____ defense against buffer overflow attacks.

Show Suggested Answer Hide Answer
Suggested Answer: A

Canaries or canary words are known values that are placed between a buffer and control data on the stack to monitor buffer overflows. When the buffer overflows, it will clobber the canary, making the overflow evident. This is a reference to the historic practice of using canaries in coal mines, since they would be affected by toxic gases earlier than the miners, thus providing a biological warning system.

I thought /GS was more about stack protection?

I thought it was B, Hex editing, but now that I think about it, that doesn't really fit with the context of buffer overflow defenses.

I recall that StackGuard and similar tools use some kind of protection mechanism, but I can't remember if it's specifically called a Canary.

I think the answer might be A, Canary. I remember studying how it works to detect buffer overflows by placing a value before the return address.

I'm not entirely sure, but I feel like I've seen questions about this before. Could it be D, Non-executing stack? That sounds familiar.

Okay, I'm pretty confident that Anomaly Detector is the right answer here. It's specifically built for anomaly detection in time series data, which is exactly what the question is asking for. And it can integrate with IoT Hub, so that seems like a perfect match.

Okay, let's think this through step-by-step. The key details are the cloud pod architecture, the WAN links, and the need to minimize the number of open ports.
