Which statement describes sensor weaknesses in general?

• A. All sensors are perfect.
• B. Some sensor systems have negligible weaknesses.
• C. All sensor systems have weaknesses that may be exploited.
• D. Weaknesses only occur during maintenance.

Answer: (C)

Sensors are never perfect. In real-world use, sensing systems face measurement noise, drift over time, calibration errors, limited ranges, and environmental influences that introduce weaknesses. They can also have security or integrity vulnerabilities, such as susceptibility to spoofing, tampering, interference, or data tampering, which means weaknesses may be exploited. Because of these factors, the idea that all sensor systems have weaknesses that may be exploited captures the general reality across different technologies and conditions. The other statements imply perfection, negligible weaknesses, or weaknesses appearing only during maintenance, which isn’t accurate in practice. Thinking this way encourages designing with redundancy, ongoing calibration and monitoring, and protections to mitigate potential exploits.
