Smart Grid Security Threat and Solutions

The Smart Grid is the roadmap for enhancing the infrastructure of every segment of the energy delivery system. This includes generation, transmission, distribution and consumption.The capabilities for smart grid systems and networks, such as distributed intelligence and broadband capabilities can greatly enhance efficiency and reliability, but they may also create much new vulnerabilities if not deployed with the appropriate security controls. Much of the technology currently in use by the grid is outdated and in many cases unreliable. A system architecture implementing should recognize security threats and capture events that result not from external threats but from internal mistakes. An effective security approach enhances reliability. Security failure occurs from people, equipment, natural causes and deliberate failures A simple perimeter defense is not sufficient; monitoring, both for events and physical actions, is required to bring the benefits of smart grid with minimal risk to this vital part of the infrastructure of modern life. This paper aims at finding out the security issues in Smart Grid and proposing solution architecture for that.
