Question

a) Rationalize why WPA2 was necessary over WPA.

b) WEP introduced Dynamic WEP to overcome its weakness. Explain the difference(s) between them.

Answer 1

Answer A.

Step 1

Actually, WPA and WPA2 are the most common security measures that are used to protect wireless Internet. Given this, we have compared the difference between WPA and WPA2.

The answer has given below:

Step 2

WPA2 has stronger security and is easier to configure than the prior options. The main difference with WPA2 is that it uses the Advanced Encryption Standard(AES) instead of TKIP.AES is able to secure top-secret government information, so it's a good option for keeping a personal device or company Wifi safe.

The main difference between WPA and WPA2:

WPA:

WPA can support older software.

WPA has shorter password required.

No enterprise solutions.

Minimal needed.

WPA2:

WPA2 only compatible with newer software.

WPA2 has longer password required.

Has enterprise option.

Significant amount needed.

So, finally when comparing WPA vs WPA2 , WPA2 is going to be the best option if your device can support it.

Answer B.

Step 1

WEP and Dynamic WEP

• Wired Equivalent Privacy (WEP) is a security algorithm for wireless networks.
• There are legacy systems and devices in certain environments that can only do WEP.
• It is the popular way for securing wireless networks.
  

Step 2

• Dynamic WEP is the combination of 802.1x technology and Extensible Authentication Protocol.
• WEP keys can be changed dynamically using Dynamic WEP security.
• It provides dynamically generated keys that can be refreshed periodically.
