Smart grid is the next generation power system which is an evolutionary regime for existing power system. The smart grids have integrated communication technology with the computing which is in contrast to the traditional power systems. The traditional power systems are not intelligent are used to track power electronics. The big challenge in implementing these smart grids is the susceptibility to cyber attacks. In a smart grid network millions of systems are connected over a communication network so prevention and detection of cyber attacks is a concern. This paper discusses the cyber security issues for smart grid. We focus on reviewing the network vulnerabilities, possible cyber attacks and there countermeasures and architectures in Smart Grid.
