Vulnerability of Smart IoT-Based Automation and Control Devices to Cyber Attacks

In modern industrial enterprises, safety always comes first. Regardless of whether it is safety against weather conditions such as fires, floods, or it is securing the building from the intrusion of unwanted person. With these sensors, these services can also provide IoT smart security devices. In the connected world of Industry 4.0, there are way too many opportunities to take control of such devices, and so with a help of a cyber attack, computer attackers would be able, in two ways, to make the device impossible to operate. The first way is to manipulate the device, disable alarm sensors, and steal the data. The second way is to misuse the device for attacking another in a reflected way. The article illustrates the possibility of how the safety sensors can be disabled, and how this safety device can be used to attack another IoT device - the thermostat. Finally, the case study demonstrates inability of IoT-based automation and control device to send alarm notifications when a threat is detected by its sensors during the DDoS attacks.
