IoT Security Problem-Solving and Analytical Questions

1. A smart home device has been compromised, allowing attackers to access the home network. If you could isolate this device without physically disconnecting it, what steps would you take to secure the network?

2. You have two IoT devices that communicate over an insecure protocol. One device has been compromised and is sending false data to the other. How would you identify which device is sending the incorrect information and what measures would you implement to rectify the situation?

3. A city has deployed a network of IoT sensors for traffic management, but the data received is inconsistent due to interference. How would you determine the source of the interference and improve the data accuracy?

4. You discover that an IoT device in a critical infrastructure setting has a known vulnerability. What is your methodology for assessing the risk it poses and the steps you would take to mitigate that risk?

5. In a scenario where an IoT device is sending sensitive data to multiple endpoints, how would you approach the task of ensuring that only authorized users can access that data?

6. There have been multiple instances of unauthorized access to IoT devices in a corporate network. How would you analyze the access logs to determine the attack vector and prevent future breaches?

7. You are tasked with designing a security protocol for a network of smart cameras. What features would you implement to protect against potential cyber attacks and ensure data privacy?

8. A company implements firmware updates for its IoT devices but fails to track which devices have been updated. Explain how you would create a process to manage and verify firmware updates across multiple devices.

9. Your team is analyzing traffic patterns to identify unusual activity in an IoT environment. Describe the analytical techniques you would apply to differentiate between normal and malicious behavior.

10. You are asked to evaluate the security risk of a third-party IoT service provider. What criteria would you use to assess their security posture and compliance with industry standards?
