Which statement correctly describes the cloud component's risk profile in IoT architecture?

• A. The cloud is always the most secure component due to centralized defense.
• B. The cloud is isolated from data flows to prevent leakage.
• C. The cloud is usually at higher risk as the central point of data aggregation.
• D. The cloud never handles command and control tasks.

Answer: (C)

In IoT architectures, the cloud acts as the central hub where data from many devices is collected, stored, and processed, and where commands or updates are issued. Because so much data and control flows through this centralized point, it becomes a high-value target for attackers. If the cloud is compromised, the impact can cascade across many devices, leading to data leakage, manipulation, or widespread disruption. Even with strong defenses, the sheer volume of data, diverse interfaces (APIs, dashboards, device-to-cloud protocols), and the need to manage trust across many endpoints expand the attack surface, making the cloud usually at higher risk. The statement that the cloud is always the most secure due to centralized defense isn’t accurate—centralization helps security in some ways but doesn’t eliminate exposure. The idea that the cloud is isolated from data flows is false because the cloud must receive and process data from devices to function. And the notion that the cloud never handles command and control tasks is incorrect since many IoT setups rely on the cloud to send commands, manage devices, and orchestrate updates.
