Question 5

What is the security benefit of network segmentation for IoT devices?

Accepted Answer

It isolates IoT devices on a separate network segment, limiting an attacker's ability to reach critical systems if an IoT device is compromised

Answer

It makes IoT devices faster

Answer

It reduces the number of IoT devices on the network

Answer

It eliminates the need for IoT device passwords

Question 6

Why is it important to disable unnecessary features and services on mobile devices?
