Which statement describes a security benefit of fog computing?

• A. It processes data closer to the source, reducing exposure of data in transit
• B. It automatically encrypts all data without keys
• C. It eliminates the need for secure communication
• D. It ensures data can never be intercepted

Answer: (A)

Fog computing stores and runs processing at the edge, near where data is produced. The security advantage here is that by handling data locally, less information needs to travel over networks. This reduces what could be exposed or intercepted in transit and allows sensitive data to be filtered or summarized before anything moves toward central servers. In other words, moving computation closer to the source lowers the amount of data that must traverse networks, cutting down the risk of data being intercepted. The other statements aren’t accurate: encryption requires keys, secure communication is still needed, and data can still be intercepted even with fog computing.
