200-301 Question 450
Single answerA network administrator is tasked with securing a wireless network for a corporate office. The network should use the most secure wireless security protocol available, ensuring protection against brute-force attacks and providing forward secrecy. Which wireless security protocol should the administrator choose?
- A
WPA
- B
WPA2-PSK
- C
WPA2-Enterprise
- D
WPA3
Show answer and explanation
Correct answer: D
Explanation
WPA3 is the most secure wireless security protocol currently available. It addresses vulnerabilities found in WPA2 and provides features like forward secrecy and protection against brute-force attacks. This makes it the ideal choice for securing a wireless network in a corporate environment.
- A. Incorrect.
WPA (Wi-Fi Protected Access) is an older security protocol that improved upon WEP but is no longer considered secure due to vulnerabilities such as susceptibility to brute-force attacks.
- B. Incorrect.
WPA2-PSK (Wi-Fi Protected Access 2 - Pre-Shared Key) is more secure than WPA but lacks features like forward secrecy and is still vulnerable to certain attacks, including KRACK (Key Reinstallation Attacks).
- C. Incorrect.
WPA2-Enterprise is more secure than WPA2-PSK because it uses 802.1X for authentication, but it still lacks the additional protections and forward secrecy provided by WPA3.
- D. Correct.
WPA3 (Wi-Fi Protected Access 3) is the latest wireless security protocol and offers the most robust security, including protection against brute-force attacks, forward secrecy, and enhanced encryption mechanisms.
