Which of the following is most likely a security concern when installing and using low-cost IoT devices in infrastructure environments?

The most likely security concern when using low-cost IoT devices in infrastructure environments is the storage of data. These devices often have limited security features, and the data they collect (which can be sensitive operational information) may be stored insecurely, transmitted unencrypted, or sent to third-party cloud services with inadequate data protection policies. This creates significant risks for data breaches and unauthorized access. While country of origin can be a concern due to potential supply chain vulnerabilities or state-sponsored espionage, it's less universally applicable to all low-cost IoT devices than data storage issues. Device responsiveness is a performance concern, not primarily a security one. Ease of deployment is a benefit, not a security concern.
