The methods of decreasing FP in Anomaly based Intrusion Prevent System by using of complex information about information system / Anton Kudin, Olga Grigorieva, Svitlana Nosok // Theoretical and Applied Cybersecurity: scientific journal. – 2024. – Vol. 6, No. 1. – P. 26-31. – Bibliogr.: 33 ref.https://ela.kpi.ua/handle/123456789/73217The main aim of this work is to optimize the efficiency of intrusion detection using complex analysis of indicators in information system by reducing the number of false positives, as well as the development of a universal technique for such optimization.Using laboratory environment with installed SIEMs Wazuh and Splunk we test the proposed optimization methods and proposed newly methodic for decreasing rating false/positive for some intrusion detecting systems.enFalse Positives OptimizationIntrusion Detection Systems (IDS)Anomalies DetectionComprehensive Behavioral AnalysisSecurity Information And Event Management (SIEM)Signatureless Intrusion Detection MethodsArticleP. 26-31https://doi.org/10.20535/tacs.2664-29132024.1.296412004.7.056.5
