ANALYSIS AND DEVELOPMENT OF THE METHODOLOGY OF EXISTING MEANS OF EARLY DETECTION AND COUNTERING THREATS TO INFORMATION SECURITY

Abstract

In the context of rapidly growing cyberattacks and increasingly sophisticated intrusion techniques, timely threat detection and response are becoming critically important. Modern early threat detection tools—such as SIEM systems, EDR solutions, and behavioral analysis technologies—enable the identification of potentially malicious activity before it results in actual damage. This paper reviews the methodologies implemented in the most widely used tools for early threat detection, classifies them based on their functional characteristics and effectiveness, and provides a comparative analysis. Based on the analysis, an approach is proposed for selecting and combining tools depending on the specifics of the protected infrastructure. Special attention is given to detection accuracy, resistance to evasion techniques, and the ability to automate incident response. The results of the study can be used to build comprehensive security systems tailored to current threats and security requirements
