CompTIA CySA+ (CS0-002) — Question 367

A security analyst conducted a risk assessment on an organization's wireless network and identified a high-risk element in the implementation of data confidentiality protection. Which of the following is the BEST technical security control to mitigate this risk?

Answer options

• A. Switch to RADIUS technology.
• B. Switch to TACACS+ technology.
• C. Switch to MAC filtering.
• D. Switch to the WPA2 protocol.

Correct answer: D

Explanation

The correct answer is D, as the WPA2 protocol is specifically designed to enhance wireless security by providing strong data encryption, thereby protecting data confidentiality. The other options, while they may serve different purposes, do not directly address the need for robust encryption in wireless communications.
