Which of the following presents the GREATEST security risk associated with Internet of Things (IoT) technology?

While monitoring can be challenging for IoT, the *inability* to monitor isn't the *greatest* risk; the underlying vulnerability from unpatched firmware is the more fundamental problem.

The existence or lack of frameworks affects assessment, but the fundamental *technical* vulnerability that allows exploitation is the absence of crucial security updates.

Widespread use itself doesn't cause the risk, but rather the *vulnerable* nature of those widespread devices, which directly correlates to the problem of lacking security updates.

Many IoT devices are developed with minimal security considerations, have long lifespans, and often lack robust mechanisms or vendor support for ongoing firmware updates to patch discovered vulnerabilities. This widespread lack of updates for known vulnerabilities creates a massive, unpatched attack surface, making devices susceptible to exploitation over extended periods.
