Which term describes an attack in which wireless IoT device communications are jammed by randomly transmitted radio signals?

• A. Access Gateway Layer
• B. Software Defined Radio Attack (SDR)
• C. Jamming Attack
• D. Cryptanalysis Attack

Answer: (C)

Jamming is a denial-of-service tactic at the physical layer that disrupts wireless communications by broadcasting interfering radio signals in the same frequency band. When IoT devices rely on a shared wireless channel, random transmissions can flood the spectrum, raise the noise floor, and prevent receivers from correctly demodulating data. The result is dropped or corrupted packets and degraded reliability, effectively blocking communication. This captures the scenario of an attack aimed at preventing wireless IoT devices from talking to each other by simple, random radio interference. Tools like software-defined radios can be used to generate such interference, but the essence is the deliberate disruption of the communication channel itself, not cryptographic breaking or architectural ideas.
