Which statement best captures the cybersecurity risk associated with IoT data collection?

• A. It eliminates all security concerns with proper encryption
• B. It creates attack vectors that can lead to data leakage
• C. It guarantees privacy by default
• D. It reduces the number of potential attackers

Answer: (B)

IoT data collection expands the attack surface by connecting a large number of devices to networks and cloud services that may have uneven security. Each device can introduce entry points through insecure interfaces, default credentials, outdated software, or weak data handling. As data moves from sensors to apps and cloud storage, it traverses multiple environments, creating opportunities for interception, exfiltration, or tampering if any link isn’t properly protected. Encryption helps protect data in transit and at rest, but it doesn’t fix insecure endpoints, poor key management, or exposed APIs, so the risk of data leakage still exists. That’s why the best description is that IoT data collection creates attack vectors that can lead to data leakage. Encryption reduces risk but does not eliminate all security concerns, privacy isn’t guaranteed by default, and adding more devices usually increases, not decreases, the potential attack surface.
