Discuss Isaca Cybersecurity-Audit-Certificate Exam Topic 4 Question 51

Which of the following is a weakness associated with the use of symmetric, private keys in wired equivalent privacy (WEP) encryption?

AKeys change periodically on networks.

BKeys are stored in the cloud.

CKeys remain unchanged on networks for extended times.

DKeys are not retrievable.

Suggested Answer: C

The use of symmetric, private keys in WEP encryption is associated with several weaknesses, one of which is that the keys often remain unchanged on networks for extended periods. This can lead to security vulnerabilities because if an attacker manages to compromise a key, they can potentially gain access to the network and decrypt data for as long as the key remains unchanged.

True, but C is a bigger issue in WEP.

Mammie 1 month ago

But A sounds tempting. Keys changing could help.

Martha 2 months ago

Agreed! It makes them vulnerable to attacks.

Karon 2 months ago

I think C is the right answer. Keys stay the same too long.

Beckie 2 months ago

But C is definitely a major weakness. Long-term keys are risky.

William 2 months ago

I feel like A could be misleading. Some networks do change keys.

Lino 2 months ago

Agreed! That makes WEP less secure.

Carli 2 months ago

I think C is the right answer. Keys don't change often.

Kaitlyn 3 months ago

But in WEP, they really don’t. C is definitely a weakness.

Colette 3 months ago

I feel like A could be misleading. Keys should change!

Winifred 3 months ago

Agreed, C makes sense. It’s a big risk.

Odette 3 months ago

I think C is the right answer. Keys don't change often.

Ammie 3 months ago

C is a big problem, but I wonder if it’s the biggest one?

B isn't true, keys aren't stored in the cloud for WEP.

Carmelina 5 months ago

Wow, I didn't realize WEP had such a flaw with key management.

Nan 5 months ago

I disagree, A is more of an issue. Keys should change often!

Geoffrey 5 months ago

C is definitely a weakness. Keys stay the same for too long.

Ernie 6 months ago

I’m surprised this is still a topic, WEP is so outdated!

Ernestine 6 months ago

B is misleading, keys aren’t typically stored in the cloud for WEP.

Jerilyn 6 months ago

Wow, I didn’t realize WEP had such a flaw with key management.

Gladys 6 months ago

I disagree, A is more of a concern. Keys should change regularly!

Tegan 6 months ago

C is definitely a weakness. Keys don’t change often enough.

Margo 6 months ago

I thought keys being stored in the cloud was a bigger issue, but now I'm leaning towards C as the weakness in WEP.

Herminia 7 months ago

I practiced a similar question, and I recall that WEP has issues with key management. So, C sounds familiar.

Tesha 7 months ago

I'm not entirely sure, but I remember something about keys being static in WEP. Maybe that's why C is the right answer?

Denise 7 months ago

I think option C makes sense because WEP keys don't change often, which could be a security risk.
