Which of the following is considered to be the GREATEST risk to information systems that results from deploying end-to-end Internet of Things (IoT) solutions?

Show Suggested Answer Hide Answer
Suggested Answer: B

The deployment of end-to-end Internet of Things (IoT) solutions significantly increases the attack surface compared to traditional IT systems. This is due to the vast number of connected devices, each potentially introducing new vulnerabilities. The heterogeneity of these devices, often with varying levels of security, can lead to more entry points for cyberattacks. Additionally, the complexity of managing and securing these numerous devices, especially when they use different communication protocols and standards, exacerbates the risk. Therefore, the expansion of the attack surface is considered the greatest risk because it amplifies the potential for unauthorized access and compromises the integrity, availability, and confidentiality of information systems.

Cloud-based systems for IoT data collection definitely have risks, but I wonder if they are more significant than the attack surface problem.

I practiced a question similar to this, and I think the proprietary protocols might create risks, but they don't seem as critical as the attack surface.

I think the use of cheap microcontrollers could lead to vulnerabilities, but I feel like the attack surface is a bigger issue overall.

I remember discussing how the larger attack surface of IoT devices could be a major concern, but I'm not entirely sure if it's the greatest risk.

I feel pretty confident that the answer is B. IoT systems connect so many more devices and endpoints, that has to be the biggest risk factor.

Okay, let me break this down. The key is understanding how IoT systems differ from traditional IT and what the biggest vulnerability would be. I'm leaning towards B.

Haha, 'cheap' microcontrollers in A? That's a good one. I'm going with B though, the attack surface is just too huge to ignore.
