What security challenge arises when IoT devices are embedded into physical objects?

• A. They are easily vandalised or stolen
• B. They become immune to hacking
• C. They require no maintenance
• D. They always have unlimited power

Answer: (A)

When IoT devices are embedded in physical objects, they face increased exposure to the real world, where someone can physically access the hardware. That makes vandalism, tampering, or theft easier, and attackers can potentially extract cryptographic keys, alter firmware, or bypass protections, compromising both the device and the system it’s part of. This tangible threat is a distinct security concern that isn’t solved just by being inside an object.

So this is the best choice because physical access creates immediate opportunities for damage or credential exposure, which is a fundamental security risk for embedded IoT. The other statements aren’t accurate: devices aren’t immune to hacking, they still require maintenance, and they don’t have unlimited power.
