How it works and where it fits

XDR Telemetry connects data sources to detection or assessment logic. Raw records become security-relevant only when timing, identity, system context, and expected behavior are considered. Rules, correlations, statistical models, and analyst decisions may work together; no single method reliably covers every attack pattern.

Practical security relevance

Operational quality is reflected in coverage, data completeness, detection time, and false-alert workload. Data sources need owners, time synchronization, retention, and quality controls. Detections should be tested, versioned, and improved using real incidents. Every meaningful alert also requires triage guidance, escalation, and possible response actions.
