Understanding Endpoint Detection and Response Solutions

As the threat landscape evolves relentlessly, organizations face growing challenges in comprehensively safeguarding the diverse endpoints comprising today’s distributed environments. Traditional perimeter-focused solutions no longer suffice, necessitating a shift towards instrumentation and control directly at the workstation layer. Endpoint detection and response (EDR) technologies have emerged as a critical component of modern security operations, offering unprecedented visibility and control to empower proactive defense.

Real-time Detection Through Unified Telemetry

Rather than relying solely on discrete antivirus products, EDR leverages a confluence of host-based signals to continuously profile normal endpoint behavior versus anomalies indicative of compromise. Privileged host sensors and APIs deliver a stream of process, file, network, and system activity to analytics platforms. These consolidate disparate endpoint data and apply statistical analysis, machine-learning (ML) models, and correlation techniques to detect even obfuscated lateral movement and data exfiltration tactics (Kim et al., 2020).

Identification of compromised or otherwise infected hosts is strengthened through the integration of external threat intelligence, including indicators of compromises (IoCs) derived from active exploits. EDR solutions dynamically update detection logic based on the latest tactics, ...
