Two major views of Smart Grid security include cybersecurity and physical security [P2030 2011], [DOE 2015a]. Although there are differences on these views, there are common aspects and many interdependencies between these views that require a unified view of security. Another perspective is that power grid information security and protection has aspects of both ICS and IT systems. Although both ICS and IT systems require information security services to combat malicious attacks, the specifics of how these services are used for the power grid depend upon appropriate risk assessment and risk control. Distinct types of attacks targeting ICS and IT systems as well as different performance requirements of these systems determine a specific priority order of the security services implemented for each system. In addition, the Smart Grid trends toward the integration of the operational and business systems require a unified view of security based on risk management instead of applying the old approach of separate techniques for IT and ICS systems. A unified approach based on risk management techniques is described in [Ray 2010].

Therefore, solutions for designing cybersecurity into the Smart Grid with the vision of surviving a cyber incident while sustaining critical energy delivery functions must be carefully engineered and require novel solutions [Hawk 2014], [Ray 2010].
