A company wants to upgrade its wireless network security to protect against offline dictionary attacks and provide stronger encryption than previous standards. Which of the following should the technician implement?
- AWPA3
- BWEP
- CWPA2
- DWPA
Show answer & explanationAnswer & explanation
Correct answer: A. WPA3
WPA3 is the current wireless security standard that uses Simultaneous Authentication of Equals (SAE) to protect against offline dictionary attacks and provides stronger encryption than WPA2. WEP and WPA are outdated and insecure, and WPA2, while still common, remains vulnerable to certain offline attacks that WPA3 addresses.
Why the other options are wrong
- B. WEP is an outdated and easily broken encryption standard.
- C. WPA2 is widely used but vulnerable to offline dictionary attacks via captured handshakes.
- D. WPA improved on WEP but is still considered weak by modern standards.
WPA3
WPA3 is the newest Wi-Fi security standard that uses Simultaneous Authentication of Equals (SAE) to protect against offline password-guessing attacks.
- Successor to WPA2
- Uses SAE instead of PSK 4-way handshake
- Resists offline dictionary attacks
Memory trick: WEP weak, WPA weaker fix, WPA2 good, WPA3 great.
