Why each option

IoT devices introduce significant security risks primarily because they often lack fundamental security measures, utilize vulnerable legacy communication protocols, and suffer from inadequate software patch management.

AIoT devices are unencrypted and unsecured.Correct

Many IoT devices are manufactured with minimal security features, often lacking strong encryption for data in transit and at rest, and may have insecure default configurations, making them inherently vulnerable to attacks.

BIoT devices are assumed to be visible to IT teams.

The risk associated with IT teams and IoT devices is often the opposite; they are frequently *not* visible or managed by IT, leading to unmonitored security risks rather than being assumed visible.

CIoT cyberattacks are targeting legacy protocols.Correct

IoT cyberattacks frequently exploit devices that rely on outdated or legacy communication protocols, which were not designed with modern cybersecurity threats in mind and often lack robust authentication or encryption.

DIoT devices only rely on a wired connection.

Many IoT devices are designed for wireless connectivity (e.g., Wi-Fi, Bluetooth), which introduces its own set of unique security challenges, disproving the notion that they only rely on wired connections.

EInternet of Medical Things (IoMT) devices are running outdated software.Correct

A major risk for IoT, including specialized IoMT devices, is the infrequent or non-existent application of security updates and patches, leaving them susceptible to known vulnerabilities in their operating systems or firmware.
