CertNexus ITS-110 Exam - Topic 1 Question 59 Discussion

An IoT security architect needs to minimize the security risk of a radio frequency (RF) mesh application. Which of the following might the architect consider as part of the design?
B) Encrypt data transmission between nodes at the physical/logical layers.
A) Make pairing between nodes very easy so that troubleshooting is reduced.
C) Prevent nodes from being rejected to keep the value of the network as high as possible.
D) Allow implicit trust of all gateways since they are the link to the internet.

Wait, are we really trusting all gateways? That seems sketchy!

Preventing node rejection sounds like it could lead to issues, but I can't recall the exact implications. Option C might not be the best approach either.

I think we had a practice question about implicit trust before. It seems risky to trust all gateways without verification, so option D feels wrong to me.

I'm not entirely sure, but I feel like making pairing easy could lead to vulnerabilities. Maybe option A isn't the best choice?

I remember we discussed the importance of encryption in our last study session. I think option B makes the most sense for securing data transmission.

I'm leaning towards option B as well. Encrypting the data at the physical and logical layers is a fundamental security control that the architect should consider. The other options don't really address the core security needs of an RF mesh application.

Option A seems like a bad idea - making pairing too easy could actually increase security risks. And option D is just plain wrong, you can't just trust all gateways implicitly. I think B is the way to go, encryption is key for securing data transmission in an RF mesh.

Hmm, I'm a bit unsure about this one. The options seem to be focused on different aspects of security, but I'm not sure which one would be the best approach for an IoT security architect. I might need to think through the tradeoffs a bit more.

This seems like a pretty straightforward security question. I'd go with option B - encrypting the data transmission between nodes is a solid way to minimize security risks in an RF mesh application.

Option C, really? Preventing nodes from being rejected? That's like saying we should keep all the stray cats in the neighborhood, just to keep the network 'valuable'. Nope, not happening.

Haha, Option A? Really? Making pairing easy for troubleshooting? That's like leaving your front door unlocked for the convenience of your delivery guy. Hard pass on that one.
