The Internet of Things (IoT) refers to a network of interconnected physical devices that collect and exchange data through the internet. The key benefits of IoT include automation, improved decision-making, cost savings, and efficiency gains.

(A) Employees can choose from a variety of devices they want to utilize to privately read work emails without their employer’s knowledge.

This is incorrect because it focuses on unauthorized access rather than a benefit of IoT. Security and monitoring are major concerns in IoT environments.

IIA Standard 2110 – Governance requires organizations to ensure adequate governance structures for IT and data security.

(B) Physical devices, such as thermostats and heat pumps, can be set to react to electricity market changes and reduce costs. ✅

This is correct because IoT enables smart devices to automatically adjust based on real-time data.

Example: Smart thermostats (e.g., Nest, Honeywell) use IoT to track energy prices and consumption, adjusting temperatures to optimize efficiency.

IIA Practice Guide "Assessing the Governance of Risks in IT Projects" highlights IoT as a tool for operational efficiency and cost savings.

(C) Information can be extracted more efficiently from databases and transmitted to relevant applications for in-depth analytics.

This relates more to big data and data analytics, not necessarily IoT.

IIA GTAG "Auditing IT Governance" discusses IoT in operational efficiency but distinguishes it from data extraction.

(D) Data mining and data collection from the internet and social networks is easier, and the results are more comprehensive.

This describes AI and machine learning rather than IoT, which primarily connects physical devices.

IIA GTAG "Auditing Cybersecurity Risk" highlights IoT risks but does not emphasize social media data mining.

IIA GTAG (Global Technology Audit Guide) – "Auditing IT Governance"

IIA GTAG – "Assessing the Governance of Risks in IT Projects"

IIA Standard 2110 – Governance

IIA GTAG – "Auditing Cybersecurity Risk"

Analysis of Answer Choices:IIA References:Thus, the most appropriate answer is B because IoT improves efficiency by automating energy consumption based on market conditions.
