CompTIA Security+ (SY0-601) — Question 733

The Chief Information Security Officer wants to prevent exfiltration of sensitive information from employee cell phones when using public USB power charging stations. Which of the following would be the BEST solution to implement?

Answer options

Correct answer: B

Explanation

The best solution is a USB data blocker, which allows power to pass through while preventing data transfer, effectively stopping exfiltration of sensitive information. DLP (Data Loss Prevention) is a broader strategy that does not specifically address the issue at public charging stations. USB OTG (On-The-Go) enables devices to connect and transfer data, which would increase risk, while disabling USB ports restricts all USB usage, limiting functionality unnecessarily.
