Which statement best describes a data security concern of IoT devices?

• A. The device being hijacked to harm another device or system
• B. Because they are small and low powered, they can't carry much software including security software leaving them open to data theft or disruption
• C. The devices being small and embedded into objects makes them easily vandalised or stolen
• D. They are immune to security threats

Answer: (B)

IoT data security is heavily shaped by the limited resources of many devices. Because these devices are small and designed to be low power, they often have little processing power, memory, or storage. That makes it hard to run robust security software and to implement strong encryption, authentication, secure updates, and other protections. When security features can’t be fully delivered, data can be exposed to interception, tampering, or theft, and the device can become a target for disruption. While other concerns like physical tampering or device hijacking can occur, the most fundamental point is that resource constraints prevent adequate security from being built in, leading to these data security risks.
