Malicious cyber-attacks on efficient modern power systems based on the Internet of Energy, which are digitized and include advanced intelligence elements, coordinating complex units such as measurement, computation, execution, and communication, cause societal risks on a small or large scale. The penetration of intelligent electronic devices, simultaneous metering technology, and information communication raise vulnerability issues. Considering the possibility of large-scale attacks due to the tight coupling between the physical and cyber layers, timely detection of cyber intrusions and robustness of defenses are critical for the reliability of advanced communication network-based cyber-physical power systems (CPPS). Accordingly, this paper provides an overview of security assessment, focusing on detecting possible cyber-attacks and defense strategies that cause instability, vulnerability, and insecurity in CPPSs. A signature, anomaly and behavior-based, hybrid, AI-scale, and state observer cyber-attack detection techniques are described, and defense fundamentals in cybersecurity, such as secure authentication, encryption, trusted access and defense technologies, and resource utilization, are discussed. Developing cyber-attack detection and defense strategies that can flexibly and dynamically respond to the unique temporal and spatial characteristics of CPPS will improve the modernization of the power grid.
