Security Challenges and Best Practices for IIoT

Abstract

Security concerns regarding the Industrial Internet of Things (IIoT) are constantly increasing, causing issues in industrial facilities, where heavy machinery and dangerous systems are operated and controlled with connected devices. Some of the recent security incidents e.g. Stuxnet worm (Advanced Persistent Threat) and theft of sensitive information in South Korea Nuclear Power Plant (Insider Threat) have shown that these attacks should be considered as the top threat to IIoT, including nuclear facilities. Yet, as industrial systems become more and more interconnected, comparable cyber-attacks could happen in other industrial domains in the future. Therefore, adequate international standards and best practices can decrease occurrence of such attacks.
