Coordinated Cyber-Attack Detection Model of Cyber-Physical Power System Based on the Operating State Data Link
نویسندگان
چکیده
Existing coordinated cyber-attack detection methods have low accuracy and efficiency poor generalization ability due to difficulties dealing with unbalanced attack data samples, high dimensionality, noisy sets. This paper proposes a model for cyber physical fusion using link detecting attacks on Cyber–Physical Power System (CPPS). The two-step principal component analysis (PCA) is used classifying the system’s operating status. An adaptive synthetic sampling algorithm reduce imbalance in categories’ samples. loss function improved according feature intensity difference of event, an integrated classifier established classification based cost-sensitive gradient boosting decision tree (CS-GBDT). simulation results show that proposed method provides higher accuracy, recall, F-Score than comparable algorithms.

متن کاملReview of Attack Detection Scheme for Cyber Physical Security System
Cyber-Physical Systems (CPSs) are characterized by integrating computation and physical processes. The theories and applications of CPSs face the enormous challenges that are (1) general workflow of cyber physical systems, (2) identifying the unique properties of cyber-physical systems and (3) discussing security mechanisms applicable to cyber physical systems. In particular, we analyze and we ...
متن کاملAdaptive, Model-Based Monitoring for Cyber Attack Detection
Inference methods for detecting attacks on information resources typically use signature analysis or statistical anomaly detection methods. The former have the advantage of attack specificity, but may not be able to generalize. The latter detect attacks probabilistically, allowing for generalization potential. However, they lack attack models and can potentially “learn” to consider an attack no...
متن کاملLocal Cyber-physical Attack with Leveraging Detection in Smart Grid
A well-designed attack in the power system can cause an initial failure and then results in large-scale cascade failure. Several works have discussed power system attack through false data injection, line-maintaining attack, and line-removing attack. However, the existing methods need to continuously attack the system for a long time, and, unfortunately, the performance cannot be guaranteed if ...
