CompTIA Security+ (SY0-601) — Question 518

The Chief Technology Officer of a local college would like visitors to utilize the school's Wi-Fi but must be able to associate potential malicious activity to a specific person. Which of the following would best allow this objective to be met?

Answer options

• A. Requiring all new. on-site visitors to configure their devices to use WPS
• B. Implementing a new SSID for every event hosted by the college that has visitors
• C. Creating a unique PSK for every visitor when they arrive at the reception area
• D. Deploying a captive portal to capture visitors’ MAC addresses and names

Correct answer: D

Explanation

The correct answer is D because a captive portal allows for the collection of MAC addresses and names, which links network usage to specific individuals. Options A, B, and C do not provide a reliable method for associating network activity with individual users, as they do not capture identifiable information which is essential for tracing malicious actions.
