The term smart grid is nebulous, in large part because standards are still being defined. While the term means different things to different stakeholders — all agree that the smart grid will bring major changes to the way that electricity is generated, transmitted, distributed and consumed.
Smart grid open communication systems are here to stay — as are cyber threats to these systems and their underlying power generation, transmission and distribution assets. Cyber threats are thwarted with cyber security. This white paper focuses on substation cybersecurity as these facilities are the heart of power transmission and distribution control and communication systems. Learn how Ethernet switches, firewalls and gateway controllers are the cybersecurity gatekeepers to substations.
