CWNP CWSP-208 Exam - Topic 1 Question 4 Discussion

Actual exam question for CWNP's CWSP-208 exam

Question #: 4
Topic #: 1

Given: ABC Corporation is evaluating the security solution for their existing WLAN. Two of their supported solutions include a PPTP VPN and 802.1X/LEAP. They have used PPTP VPNs because of their wide support in server and desktop operating systems. While both PPTP and LEAP adhere to the minimum requirements of the corporate security policy, some individuals have raised concerns about MS-CHAPv2 (and similar) authentication and the known fact that MS-CHAPv2 has proven vulnerable in improper implementations.

As a consultant, what do you tell ABC Corporation about implementing MS-CHAPv2 authentication? (Choose 2)

AMS-CHAPv2 is compliant with WPA-Personal, but not WPA2-Enterprise.

BMS-CHAPv2 is subject to offline dictionary attacks.

CLEAP's use of MS-CHAPv2 is only secure when combined with WEP.

DMS-CHAPv2 is only appropriate for WLAN security when used inside a TLS-encrypted tunnel.

EMS-CHAPv2 uses AES authentication, and is therefore secure.

FWhen implemented with AES-CCMP encryption, MS-CHAPv2 is very secure.

MS-CHAPv2 isn't compliant with WPA2-Enterprise, just a heads up!

Using it inside a TLS tunnel could help, but still risky.

Totally agree, it's not the best choice for security.

MS-CHAPv2 is definitely vulnerable to offline dictionary attacks.

Wait, does anyone really think MS-CHAPv2 is secure?

I vaguely recall that using MS-CHAPv2 inside a TLS-encrypted tunnel could make it more secure, but I’m not confident about that.

I practiced a question about LEAP and WEP, and I think it mentioned that LEAP's security relies heavily on WEP, which isn't great.

I’m not entirely sure, but I think MS-CHAPv2 is compliant with WPA-Personal but not WPA2-Enterprise. That seems important for their WLAN.

I remember reading that MS-CHAPv2 can be vulnerable to offline dictionary attacks, so I think that's a concern we should address.

The key here is that MS-CHAPv2 has known vulnerabilities, even if it meets the minimum security requirements. I'd recommend using a more secure authentication method if possible.

Wait, I thought MS-CHAPv2 was compliant with WPA2-Enterprise. I'm not sure about the WPA-Personal part. I'll have to double-check that.

Okay, I remember learning that MS-CHAPv2 should only be used within a TLS-encrypted tunnel for WLAN security. That seems like the most secure approach.

Hmm, I'm a bit confused about the LEAP part. I know LEAP uses MS-CHAPv2, but I'm not sure if it's only secure with WEP. I'll have to think about that one.

I'm pretty confident about this one. MS-CHAPv2 is definitely vulnerable to offline dictionary attacks, so that's an easy choice.

F) When implemented with AES-CCMP encryption, MS-CHAPv2 is very secure. Sounds like a plan to me, as long as we don't forget to throw in some pixie dust and unicorn tears for good measure.

I can't believe they're still using PPTP VPNs. That's like using a cardboard box to protect your valuables!

D) MS-CHAPv2 is only appropriate for WLAN security when used inside a TLS-encrypted tunnel. This helps mitigate the security risks associated with MS-CHAPv2.
