Industrial Cybersecurity for Power System and SCADA Networks

Many industrial control strategies now employ intranet and internet technologies. They create challenges for security measures in terms of implementation and enforcement. This is because these control systems can have detrimental effects if intruded, such as environmental damage, safety risks, poor quality, and lost production. This paper gives methods and a procedure to quantify and reduce the vulnerability of intrusions on networked control systems. These assessment results allow network designers to plan infrastructure expansion with security as a top priority. Several case studies of real incidents are used as models. Recommendations that are consistent with current industry best practices include policy development, architectural review, review of external connections, system vulnerabilities, device vulnerabilities, segmentation of systems, and physical security.
