Smart Grid Cyber-Attack Analysis and Countermeasures.

The smart grid, a key component of Industry 4.0, is critical in promoting sustainable social and economic development. The traditional grid and computer technologies are integrated into this next-generation electrical power system to improve automation, connectivity, and communication. Testing on an existing system is risky and challenging due to the smart grid's complexity, which has two crucial components: electrical grid and network communication. Simulating and analyzing this system could be an effective solution for experimenting with smart grid cybersecurity. This research identified the necessity for practical cybersecurity experimentation for the smart grid, and a method-ology was proposed to enable such investigation successfully. Furthermore, a general smart grid cybersecurity architecture that satisfies these requirements was designed and implemented in two systems named GridAttackSim and GridAttackAnalyzer. By employing these systems, countermeasures against cyber-attacks can be investigated, thus helping researchers determine the implications of various attack types and allowing for the early development and evaluation of new anomaly detection methods and mitigation strategies before deployment.
