CompTIA Security+ - Securing Wireless and Mobile Devices Example Questions

Test your knowledge of Securing Wireless and Mobile Devices

Question 1

A marketing event team has Bluetooth beacons that broadcast promotional information to passersby. However, a competitor has been exploiting weaknesses in the beacons. Which security measure should be implemented to increase security?

Correct Answer: Implementing MAC address randomization

Implementing MAC address randomization periodically changes the beacons' MAC addresses, making it more difficult for attackers to target and exploit the beacons. Removing the PIN requirement, disabling firmware updates, decreasing transmission power, allowing open access, or using default names would all likely increase security vulnerabilities.

Question 2

Your company's MDM policy does not allow employees to use their own mobile devices for work. However, some employees still use their personal devices for sensitive activities. What MDM solution should be implemented?

Correct Answer: Containerization

Containerization separates personal and corporate data on the mobile device, allowing your company to manage the corporate container while keeping the employees' personal data private. This solution is suitable for Bring Your Own Device (BYOD) policies.

Question 3

A company's employees are given access to their work email on their personal smartphones. Which security policy would be most effective in preventing unauthorized access to these emails?

Correct Answer: Require strong passwords and regular password changes

Ensuring employees have strong passwords and change them regularly minimizes the risk of unauthorized access to their work emails. While other methods can protect data in different ways, a strong password policy directly addresses unauthorized access to emails.
