200-301 Question 452
Single answerA network administrator is configuring a wireless network for a corporate office. The goal is to implement the most secure wireless security protocol available to protect against eavesdropping and brute-force attacks while maintaining compatibility with modern devices. Which wireless security protocol should the administrator choose?
- A
WPA
- B
WPA2 with TKIP
- C
WPA2 with AES
- D
WPA3
Show answer and explanation
Correct answer: D
Explanation
WPA3 is the latest wireless security protocol and offers significant improvements over previous versions like WPA and WPA2. It includes features such as Simultaneous Authentication of Equals (SAE) for stronger protection against brute-force attacks and forward secrecy to protect data even if a key is compromised. This makes WPA3 the most secure choice for modern wireless networks.
- A. Incorrect.
WPA (Wi-Fi Protected Access) is an older protocol that introduced improvements over WEP but is now considered insecure due to vulnerabilities such as susceptibility to brute-force attacks.
- B. Incorrect.
WPA2 with TKIP (Temporal Key Integrity Protocol) is more secure than WPA but still vulnerable to some attacks, especially since TKIP is outdated and less secure compared to AES.
- C. Incorrect.
WPA2 with AES (Advanced Encryption Standard) is highly secure and widely used, but it does not include some of the advanced protections offered by WPA3, such as better defense against brute-force attacks and forward secrecy.
- D. Correct.
WPA3 (Wi-Fi Protected Access 3) is the latest and most secure wireless security protocol, offering enhanced encryption, protection against brute-force attacks, and forward secrecy. It is the best choice for modern networks prioritizing security.
