Which of the following is the BEST way for home users to mitigate vulnerabilities associated with IoT devices on their home networks?
Click on the arrows to vote for the correct answer
A. B. C. D.C.
The BEST way for home users to mitigate vulnerabilities associated with IoT (Internet of Things) devices on their home networks is to apply firmware and software updates upon availability. Therefore, option C is the correct answer.
IoT devices are widely used in homes, but they can create security risks due to their connection to the internet and the potential vulnerabilities in their firmware and software. By applying firmware and software updates as soon as they become available, home users can reduce the risk of attacks exploiting known vulnerabilities.
Option A, powering off devices when not in use, may help in conserving energy, but it is not an effective security measure as it does not address the root cause of the security vulnerabilities in IoT devices.
Option B, preventing IoT devices from contacting the internet directly, may help to reduce the risk of attacks, but it may also limit the functionality of the devices, as they may rely on internet connectivity for essential features.
Option D, deploying a bastion host on the home network, is not an effective solution for home users as it requires technical expertise and resources that are beyond the reach of most home users. A bastion host is a specialized computer system that is designed to provide secure access to a network from an external network, and it requires additional hardware and software configurations to set up and maintain.
Therefore, the best approach for home users to mitigate IoT device vulnerabilities is to keep their devices updated with the latest firmware and software updates as they become available.
