GIAC GSNA Exam - Topic 5 Question 45 Discussion

Wired Equivalent Privacy (WEP) is a security protocol for wireless local area networks (WLANs). It has two components, authentication and encryption. It provides security equivalent to wired networks for wireless networks. WEP encrypts data on a wireless network by using a fixed secret key. Which of the following statements are true about WEP?Each correct answer represents a complete solution. Choose all that apply.
C) It provides better security than the Wi-Fi Protected Access protocol. and D) Automated tools such as AirSnort are available for discovering WEP keys.
A) WEP uses the RC4 encryption algorithm.
B) The Initialization Vector (IV) field of WEP is only 24 bits long.

[All GSNA Questions]

Wired Equivalent Privacy (WEP) is a security protocol for wireless local area networks (WLANs). It has two components, authentication and encryption. It provides security equivalent to wired networks for wireless networks. WEP encrypts data on a wireless network by using a fixed secret key. Which of the following statements are true about WEP?

Each correct answer represents a complete solution. Choose all that apply.

Show Suggested Answer Hide Answer
Suggested Answer: C, D

The getSession() method of the HttpServletRequest interface returns the current session associated with the request, or creates a new

session if no session exists. The method has two syntaxes as follows:

public HttpSession getSession(): This method creates a new session if it does not exist.

public HttpSession getSession(boolean create): This method becomes similar to the above method if create is true, and returns the

current session if create is false. It returns null if no session exists.

Answer B is incorrect. The getSession(false) method returns a pre-existing session. It returns null if the

client has no session

associated with it.

Answer A and E are incorrect. There is no such method as getNewSession() in Java.

I feel like I read somewhere that WEP is actually less secure than WPA, so I think option C is definitely false.

I think the IV field is indeed 24 bits long, but I’m a bit confused about whether it’s the only thing that makes WEP weak compared to WPA.

Okay, let's see. I know WEP has some security issues, so I'll focus on identifying the true statements that highlight those weaknesses, like the short IV length and availability of tools to crack the keys.

Okay, I've got this. I'll edit the existing request and select 'Month' first, then 'Country' in the wizard. That should give me the breakdown by month and purchase country that the question is asking for.

Ah, the good old days of WEP. Back when we thought 24-bit IVs were secure and RC4 was cutting-edge. Time to move on to newer, stronger protocols!

C is definitely false - WEP is widely known to have security flaws, while WPA offers much stronger protection. And D is spot on, there are plenty of tools out there that can crack WEP keys easily.
