Cyber physical systems integrate the electronic and the physical worlds. Given the cyber-physical characteristics of many IoT devices, some types of device vulnerabilities can be safety-of-life critical.
For example, if someone were to compromise a pacemaker via an exposed, low-power, wireless interface, obvious malicious acts could be performed. Likewise, if a modern automobile's electronic control units (ECUs) are compromised over its CAN Bus OBD2 interface, the new access may allow an attacker to send malicious messages over the CAN bus to safety-critical ECUs, such as those that perform the braking function of the car.
A safety impact assessment should be performed for any IoT deployment. In the medical ...
