Classifying resilience approaches for protecting smart grids against cyber threats

Abstract Smart grids (SG) draw the attention of cyber attackers due to their vulnerabilities, which are caused by usage heterogeneous communication technologies and distributed nature. While preventing or detecting attacks is a well-studied field research, making SG more resilient against such threats challenging task. This paper provides classification proposed resilience methods for SG. includes set studies that propose cyber-resilient approaches protect related cyber-physical systems unforeseen anomalies deliberate attacks. Each study briefly analyzed associated with proper technique given National Institute Standards Technology in Special Publication 800-160. These techniques also linked different states typical curve. Consequently, this highlights most critical challenges achieving resilience, reveals significant aspects have not been sufficiently considered yet and, finally, proposes scientific areas should be further researched order enhance
