Actual exam question for GIAC's GSNA exam
Question #: 33
Topic #: 1
[All GSNA Questions]

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.

to replace both TKIP and WEP.

Show Suggested Answer Hide Answer
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?

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

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

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

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.

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

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.

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.

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.

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.
