Industrial Automatic Control Systems and Controllers Annotation << Back Security Information and Event Management Systems: Challenges and Opportunities A.G. Mustafayev, Z.Kh. Akhmedova Security Information and Event Management (SIEM) systems are widely used as a powerful tool for preventing, detecting and responding to security incidents. SIEM solutions are complex systems that identify areas of information infrastructure with high information security risks and allow you to quickly implement escalation strategies aimed at reducing costs and time to respond to incidents. The paper considers the functional characteristics of SIEM, ways of interacting with SIEM with the surrounding information infrastructure. The requirements for promising SIEM solutions are formulated, which should use methods that combine statistical and multi-criteria analysis to form a model of application operation and user behavior, and subsequent identifi cation of statistically signifi cant anomalies and deviations from the obtained behavior models.
