Security of IT/OT Convergence: Design and Implementation Challenges (2302.09426v1)

Abstract: IoT is undoubtedly considered the future of the Internet. Many sectors are moving towards the use of these devices to aid better monitoring, controlling of the surrounding environment, and manufacturing processes. The Industrial Internet of things is a sub-domain of IoT and serves as enablers of the industry. IIoT is providing valuable services to Industrial Control Systems such as logistics, manufacturing, healthcare, industrial surveillance, and others. Although IIoT service-offering to ICS is tempting, it comes with greater risk. ICS systems are protected by isolation and creating an air-gap to separate their network from the outside world. While IIoT by definition is a device that has connection ability. This creates multiple points of entry to a closed system. In this study, we examine the first automated risk assessment system designed specifically to deal with the automated risk assessment and defining potential threats associated with IT/OT convergence based on OCTAVE Allegro- ISO/IEC 27030 Frameworks.
