Discuss GIAC GSNA Exam Topic 1 Question 33

Fill in the blanks with the appropriate protocol.

CCMP (Counter Mode with Cipher Block Chaining Message Authentication Code Protocol) is an IEEE encryption protocol created

to replace both TKIP and WEP.

ACCMP (Counter Mode with Cipher Block Chaining Message Authentication Code Protocol) is an IEEE 802.11i encryption protocol created

Suggested Answer: A

created to replace both TKIP, the mandatory protocol in WPA, and WEP, the earlier, insecure protocol. CCMP is a mandatory part of the WPA2

standard, an optional part of the WPA standard, and a required option for Robust Security Network (RSN) Compliant networks. CCMP is also

used in the ITU-T home and business networking standard.

CCMP, part of the 802.11i standard, uses the Advanced Encryption Standard (AES) algorithm. Unlike in TKIP, key management and message

integrity is handled by a single component built around AES using a 128-bit key, a 128-bit block, and 10 rounds of encoding per the FIPS 197

standard.

I thought TKIP was still in use in some places?

Jonelle 11 months ago

Yup, it's part of the 802.11i standard.

Aja 11 months ago

Wait, is CCMP really that much better?

Merlyn 11 months ago

Agreed! It's way more secure.

Myong 11 months ago

CCMP is definitely better than TKIP and WEP!

Mabelle 12 months ago

I’m a bit confused about the specifics of the protocols, but I think CCMP is definitely the right choice here.

Jolanda 12 months ago

Wasn’t there something about how CCMP uses AES for encryption? I feel like that’s important for this question.

Jose 12 months ago

I remember practicing a question about TKIP and WEP, and CCMP was highlighted as the stronger alternative. This seems familiar!

Ashlyn 12 months ago

I think CCMP is definitely related to 802.11i, but I’m not entirely sure if it’s the only protocol mentioned in that standard.

I think I know the answer, but I want to make sure I phrase it correctly. Let me re-read the question carefully before responding.

No problem, I've got this. CCMP is the IEEE encryption protocol that replaced the older and less secure TKIP and WEP protocols.

Selene 1 year ago

This is a good opportunity to showcase my knowledge of wireless security protocols. I'll make sure to provide the complete name and mention that it's an IEEE 802.11i protocol.

Tanesha 1 year ago

Hmm, I'm a bit unsure about the exact protocol name. I'll need to double-check my notes to make sure I get the wording right.

Rochell 1 year ago

Okay, this looks straightforward. I'll just need to remember the full name of the CCMP protocol and that it was created to replace TKIP and WEP.

I'm not sure about this one. I know search results aren't in chronological order, but I can't remember if they're in reverse chronological or alphabetical order. I'll have to think about this one.

Arminda 1 year ago

I think I've seen this topic covered in the study materials, so I should be able to handle this one. Let me think it through carefully.

Louvenia 1 year ago

I've got a good strategy for this. I'll eliminate the options that don't seem directly relevant to the internal audit's role, and then choose the one that best aligns with the guidance.

Izetta 1 year ago

Hmm, I'm a bit unsure about this one. I need to make sure I understand all the requirements listed in the question before selecting an answer.
