EDR AND XDR AS THE MAIN ENDPOINT SECURITY TECHNOLOGIES

Abstract

The article analyzes the role of Endpoint Security as a key element of modern IT infrastructures, which plays a key role in countering cyber threats at the initial stage of attacks. Traditional tools, such as EPP (Endpoint Protection Platform), which are based on signature analysis and blocking known threats, are considered. A detailed review of EDR (Endpoint Detection and Response) highlights its advantages: continuous real-time monitoring of endpoint activities, the use of machine learning to identify anomalies, and behavioral analytics to detect suspicious activity. EDR provides not only detection, but also automated response mechanisms: blocking suspicious activities, isolating devices from the network, and removing malicious code. XDR (Extended Detection and Response) is presented as an evolutionary development of EDR, where data analysis takes place at the level of the entire infrastructure. The technology aggregates information from endpoints, network sensors, cloud services, email, and SIEM systems to provide a comprehensive view of threats. XDR automates the correlation of events, detects complex attacks that span different network segments, and accelerates response through centralized management (e.g., simultaneously blocking threats in different environments). A comparison of EDR and XDR demonstrates that the latter eliminates the fragmentation of tools, provides a single interface for monitoring, and reduces the operational burden on security teams. Examples of technology implementation are described below: FortiManager, a tool for centralized management of security policies, configuration of firewalls, monitoring events in different network segments, and coordination of EDR solutions; Symantec Endpoint Security Complete, a platform that combines EDR, antivirus protection, application control, data encryption, and protection against exploits, providing multi-level protection for corporate devices.
