报告内容简介：

Cybersecurity has quickly become a big social problem of the 21st century, and innovative solutions are needed to ensure the cybersecurity of society. Recent advances in artificial intelligence (AI) technologies have led to increased innovation and automation of information security processes. Modern Industrial Internet of Things (IIoT) networks combine many devices and sensors that transmit and process large amounts of data. Security tools identify security events that contain information about detected system or network states. In turn, AI methods are required to ensure stability and reliability of IIoT processes. In the field of cybersecurity, AI methods are necessary for detection and prediction of incremental threats, such as multi-stage or targeted attacks (advanced persistent threats) and other causal sequences of abnormal events. Information about the correlation of security events can be used to detect and explain deviations from normal states and cyberattacks. The use of methods of correlation also makes it possible to reduce the volume of the original data stream by grouping them and eliminating redundancy. The talk shows the state of the art in the use of AI for cybersecurity (both by attackers and defense against attacks), in common, and for Security Event Correlation in IIoT networks, in particular. It systematizes event correlation technologies according to applied mathematical methods, used data sources and architectural solutions. This talk also proposes an anomaly detection approach based on the casual correlation of security events using machine learning. The proposed approach does not require prior knowledge of event scenarios. Using cluster analysis and a recurrent neural network, a security state correlation graph corresponding to the normal behavior of the system is constructed. Cluster analysis determines the similarity of events to each other. A recurrent neural network, represented by an LSTM, analyzes the temporal relationships of events. Using the identified event correlation thresholds, anomalies can be detected in real time. Experimental results on an Internet of Things sensor dataset show that the proposed method is efficient in anomaly detection tasks. As the results of the analysis, the main directions of research in the field of event correlation, existing problems and possible ways to overcome them are defined. This research is being supported by the grant of Russian Science Foundation #21-71-20078.
