CompTIA Security+ (SY0-501) — Question 388

Which of the following is the BEST way for home users to mitigate vulnerabilities associated with IoT devices on their home networks?

Answer options

• A. Power off the devices when they are not in use.
• B. Prevent IoT devices from contacting the Internet directly.
• C. Apply firmware and software updates upon availability.
• D. Deploy a bastion host on the home network.

Correct answer: C

Explanation

Applying firmware and software updates is critical because these updates often include security patches that protect against vulnerabilities. While powering off devices and preventing direct Internet access can improve security, they do not address the underlying vulnerabilities that updates fix. Deploying a bastion host may enhance security, but it is more complex and not always necessary for home users.
