Question

A user asks a security practitioner for recommendations on securing a home network. The user recently purchased a connected home assistant and multiple loT devices in an effort to automate the home Some of the loT devices are wearables, and others are installed in the user's automobiles. The current home network is configured as a single flat network behind an ISP-supplied router. The router has a single IP address, and the router performs NAT on incorning traffic to route t to individual devices Which of the following security controls would address the user's privacy concerns and provide the BEST level of security for the home network? Ensure all loT devices are configured in a geofencing mode so the devices do not work when removed from the home network Disable the home assistant unless actively using it, and segment the network so each loT device has its own segment network access for the home assistant based on time-of-day restrictions Segment the network traffic, require strong authentication to access all loT devices, and restrict O C home network to separate network traffic from users and the loT devices, ensure security settings on the home assistant support no or lirmited recording capability, and install firewall rules on the router to restrict traffic to the home assistant as much as possible O D ge all default passwords on the loT devices, disable Internet access for the loT devices and the home assistant, obtain routable IP addresses for all devices, and implement IPv6 ar

Explanation / Answer

A Reason - When connected to home network all the IoT devices can work synchronously with each other and when removed from the network they should stop working so that no attacker gets the access to them when disconnected from home network. Also, when home assistant is not in use, its better to disable it, and make sure each assistant has its own private segment so that one Iot decive works independently of the other.
