Balancing the Demands of Reliability and Security Cyber Security for Substation Automation, Protection and Control Systems
ثبت نشده
چکیده
In the past decade, substation automation, protection and control systems have changed significantly, and this transformation promises to continue as increasing demands on the utility infrastructure mandate continued technology advancements. Systems have become more interconnected, providing end users with much more information and enabling higher reliability and greater levels of control. Interoperability between different vendor products and systems has been achieved through product and solution development based on open standards, and by leveraging commercial technologies like standard Ethernet. These technological advances have not only delivered significant operational benefits, but have also increased the exposure of substation automation, protection and control systems to cyber security issues similar to those faced for years by other traditional enterprise systems.
