A survey on Classification of Cyber-attacks on IoT and IIoT devices

Internet of Things (IoT) devices have gained popularity in recent years. With the increased usage of IoT devices, users have become more prone to Cyber-attacks. Threats against IoT devices must be analyzed thoroughly to develop protection mechanisms against them. An attacker's purpose behind launching an attack is to find a weak link within a network and once discovered, the devices connected to the network become the primary target for the attackers. Industrial Internet of Things (IIoT) emerged due to the popularity of IoT devices and they are used to interconnect machines, sensors, and actuators at large manufacturing plants. By incorporating IIoT at their facilities companies have benefited by reducing operational costs and increasing productivity. However, as IIoT relies on utilizing the Internet to operate it is vulnerable to Cyber-attacks if security is not taken into consideration. After seeing the advantages of IIoT, a new version of smart industries has been introduced called Industry 4.0. Industry 4.0 combines cloud and fog computing, cyber-physical systems (CPS), and data analytics to automate the manufacturing process. This paper surveys the different classifications of attacks that an attacker can launch against these devices and mentions methods of mitigating such attacks(1).
