This is a close network, so the answer is D Restricts network communication to only pre-authorized IP addresses(from IoT devices), blocking all other incoming/outgoing traffic.

Selected Answer: D

The question is about how to prevent attacks. IDS only detects threats. Systems like traffic control, water supply, and power grid management are accessed by administrators, so it's essential to allow access only from specific IP segments.

Nah fam that ain't correct, it's C because even if you have it whitelisted anyone can just spoof the IP and get through which is even worse. IDS works alongside firewalls and make adaptive rules accordingly based off of that.
