CompTIA Security+ (SY0-501) — Question 223

Joe, a technician, is working remotely with his company provided laptop at the coffee shop near his home. Joe is concerned that another patron of the coffee shop may be trying to access his laptop.
Which of the following is an appropriate control to use to prevent the other patron from accessing Joe's laptop directly?

Answer options

• A. full-disk encryption
• B. Host-based firewall
• C. Current antivirus definitions
• D. Latest OS updates

Correct answer: B

Explanation

The correct answer is B, as a Host-based firewall can help protect against unauthorized access attempts from other devices on the same network. Full-disk encryption (A) secures data at rest but does not prevent access while the device is in use. Current antivirus definitions (C) and latest OS updates (D) enhance security in other ways but do not specifically address direct access to the laptop.
