| Summary: | Digital Revolution has forced previously isolated networks of critical infrastructures to become more digitally integrated. Recent cyber-attacks, including Stuxnet and Wiper, have exposed a new set of cybersecurity vulnerabilities in this field. This new environment has forced previously isolated networks of critical infrastructures like utilities or power plants to become more digitally integrated. This paper offers a view into the most efficient current defense solutions. It also offers a glimpse into the need for the further development of new protection mechanisms developed on the emerging new technologies. The risks posed by the integration of Information Technology solutions with Operational Technology systems have been a key topic also at the latest World Economic Forum conference, where cyber-attacks of critical infrastructures were discussed in the context of the most significant risks for the upcoming decade. The findings of this paper are applicable to other industries. The paper aims to highlight that by initially understanding the vulnerabilities of the IT components and by taking the right cybersecurity preventive measures, critical infrastructure can be protected against these kinds of threats. The research framework behind this paper was directed towards analysing the cyber risks associated with the convergence between the Information Technology solutions with the Operational Technology systems of critical infrastructure.
