Critical infrastructure encompasses both physical and digital systems vital for a country’s economic stability and public well-being. Safeguarding these systems from cyber threats is a fundamental component of cybersecurity. These sectors involve assets managed by government bodies and private entities, often intertwining in sectors like Energy and Financial Services, where a disruption on one side can impact the other, ultimately affecting the nation’s life safety and economic security.
Notably, these critical infrastructure systems encompass a blend of government-owned and privately owned assets. Many of these sectors rely on “cyber-physical systems,” which go beyond traditional IT systems and encompass OT/IoT/ICS/IIoT and other technologies that control both data and physical processes. Gartner defines “cyber-physical systems” as “engineered systems orchestrating sensing, computation, control, networking, and analytics to interact with the physical world, including humans.” When secured effectively, these systems enable safe, real-time, reliable, resilient, and adaptable performance. Using this broader perspective, Gartner encourages security and risk leaders to expand their security programs to cover the full spectrum of cyber-physical risk.
