200-301 Question 453
Single answerA network administrator is securing a wireless network in a corporate environment that handles sensitive data. They want to implement the most secure wireless security protocol available to protect against modern threats, such as brute-force attacks and compromised encryption keys. Which wireless security protocol should they choose?
- A
WEP
- B
WPA
- C
WPA2
- D
WPA3
Show answer and explanation
Correct answer: D
Explanation
WPA3 is the most secure wireless security protocol as it introduces advanced features such as Simultaneous Authentication of Equals (SAE) for stronger protection against brute-force attacks and forward secrecy to prevent compromised encryption keys from exposing past communications. This makes it the optimal choice for environments handling sensitive data, whereas older protocols like WPA2, WPA, and WEP have known vulnerabilities.
- A. Incorrect.
WEP (Wired Equivalent Privacy) is an outdated and insecure protocol with known vulnerabilities, making it unsuitable for securing modern wireless networks.
- B. Incorrect.
WPA (Wi-Fi Protected Access) was an improvement over WEP but still has vulnerabilities such as susceptibility to certain brute-force attacks. It is no longer considered the best option for securing wireless networks.
- C. Incorrect.
WPA2 (Wi-Fi Protected Access 2) provides strong encryption using AES but lacks protections against modern attacks such as offline dictionary attacks, making it less secure than WPA3.
- D. Correct.
WPA3 (Wi-Fi Protected Access 3) is the most secure wireless security protocol currently available. It introduces stronger encryption, protection against offline dictionary attacks, and forward secrecy, making it the best choice for securing sensitive corporate environments.
