The target is on the back of industrial control systems (ICS) within the power and process industries. The number of attacks, as reported by the Industrial Control Systems Cyber Emergency Response Team (ICS-CERT), has increased fourfold since 2010. Control systems at industrial facilities present a more attractive target to hackers as they offer a greater opportunity to exert control over the plant and cause potentially catastrophic damage. The attacks are growing in sophistication as hackers become more knowledgeable about the proprietary systems at the center of plant operations.
The challenge the industry now faces is hardening ICS cybersecurity before a potentially devastating attack occurs. In this paper, we will discuss the current state of cybersecurity in the industry and best practices for implementing a comprehensive ICS cybersecurity strategy.
