Industrial IoT (IIOT): Security Threats and Countermeasures

IoT makes a system of intelligent machines, objects, people, and/or other things internet connected, opening them up to major dangers and attacks. Research analysis of IoT evolution, concentrating on security concerns and suggested solutions. Despite raising severe concerns about data security and privacy, the integration of Industry 4.0 and IoT has created new opportunities for the creation, processing, and exchange of enormous volumes of data. Industrial IoT devices are susceptible to cyberattacks due to their internet connectivity and extensive data exchange, which can result in the disclosure of confidential information and monetary loss. Study analyses numerous suggested countermeasures, such as authentication methods, key establishment methods, and intrusion detection methods, to provide security at various IIoT surfaces. Research Limited within Industrial IOT. Research finds future challenges of technology in term of data security, infrastructure, connectivity and long-life equipment.
