CWNP CWSP-207 Exam - Topic 3 Question 14 Discussion

In an effort to optimize WLAN performance, ABC Company has upgraded their WLAN infrastructure from 802.11a/g to 802.11n. 802.11a/g clients are still supported and are used throughout ABC's facility. ABC has always been highly security conscious, but due to budget limitations, they have not yet updated their overlay WIPS solution to 802.11n or 802.11ac.Given ABC's deployment strategy, what security risks would not be detected by the 802.11a/g WIPS?
B) Rogue AP operating in Greenfield 40 MHz-only mode
A) Hijacking attack performed by using a rogue 802.11n AP against an 802.11a client
C) 802.11a STA performing a deauthentication attack against 802.11n APs
D) 802.11n client spoofing the MAC address of an authorized 802.11n client

I think option D is also a risk, spoofing is always a problem.

I recall something about MAC address spoofing, but I'm not sure if that would be detected by the older WIPS. It seems tricky.

I think a rogue AP in Greenfield mode could be a risk since the older WIPS might not detect it. That sounds familiar from practice questions.

I remember studying how older WIPS solutions might not recognize newer attack vectors, especially with 802.11n clients.

This is a tricky one. I know the 802.11n standard has some new capabilities that could be exploited, but I'm not sure exactly what the WIPS would miss. I'll need to review my notes on the differences between the standards to figure this out.

Okay, I think I've got this. The 802.11a/g WIPS wouldn't be able to detect attacks that take advantage of 802.11n features, like the Greenfield mode or the higher bandwidth. I'll make sure to read through the answer choices closely.

This question seems pretty straightforward. I think the key is to focus on the differences between 802.11a/g and 802.11n, and how the older WIPS might not be able to detect certain attacks targeting the newer standard.

Hmm, I'm a bit confused on this one. The question is asking about security risks that the 802.11a/g WIPS wouldn't detect, but it's not totally clear to me what those might be. I'll need to think it through carefully.

I'm going with D. If the WIPS is only 802.11a/g, it won't be able to catch an 802.11n client spoofing an authorized client's MAC.

Definitely B. The WIPS can't detect rogue APs operating in 40 MHz-only mode, which is a huge security risk.

I'm going to have to go with C on this one. Seeing an 802.11a STA perform a deauthentication attack against the 802.11n APs would definitely slip under the radar of that legacy WIPS.

Haha, these security questions always make me feel like I'm in a spy movie! But seriously, I think B is the right answer. The WIPS is just not equipped to handle those newer 802.11n shenanigans.

I think the security risks that would not be detected by the 802.11a/g WIPS are hijacking attacks using rogue 802.11n APs against 802.11a clients.
