The three main reasons for the introduced risks associated with IoT devices are: 1) IoT devices are unencrypted and unsecured, which makes them vulnerable to various attacks and unauthorized access. 2) IoT cyberattacks are targeting legacy protocols, as these protocols are outdated and often lack adequate security features, making them an easy target for attackers. 3) Internet of Medical Things (IoMT) devices are running outdated software, which can contain unpatched vulnerabilities that can be exploited by attackers. These factors collectively contribute to increased risks associated with IoT devices.
