Interconnected systems in the energy industry increase cyber vulnerabilities, with cyber attacks often going undetected for some time. Malicious actors are increasingly targeting critical infrastructure (CNI) sites and distribution facilities for energy, and cyber attacks have real-world effects. As energy companies save costs against the backdrop of a lower oil price, consolidating operations can weaken business resilience and redundancy levels. This gives rise to new, single critical points of failure, with any disruption across the supply chain potentially having increased consequences. Cyber attacks using individual vulnerabilities and exploits have, and always will be directed against the vast number of Programmable Logic Controllers (PLCs) in existence. However, connecting Industrial Control Systems (ICS) to the Internet and enterprise business networks is increasing. These factors, plus fewer backups in place with an increased dependency on fewer facilities, are only part of the picture.
