An IoT security administrator is concerned that someone could physically connect to his network and scan for vulnerable devices. Which of the following solutions should he install to prevent this kind of attack?
This is a tricky one. I think the administrator is looking for a solution that can actively block unauthorized access, not just detect it. That makes me think NAC is the best choice here.
I'm a little confused on the differences between these options. Is MAC just controlling the physical layer access, or does it do more? I'm leaning towards NAC but want to make sure I understand the distinctions.
Okay, I've got this. The key is to prevent physical access to the network, so the right answer has to be something that controls who can connect, not just detect intrusions. I'm going with NAC.
Hmm, I'm not totally sure about this one. I'm debating between NAC and NIDS, since both could potentially help prevent unauthorized access and scanning. I'll have to think it through carefully.
This seems like a straightforward question. I think the answer is Network Access Control (NAC) since that's designed to control and monitor access to the network.
I believe Host Intrusion Detection System (HIDS) could also be a good solution to detect any suspicious activity on individual devices within the network.
