The Detection and Analysis phase focuses on recognizing that an event has occurred and determining whether it constitutes a security incident. Correlating SIEM alerts and examining network traffic are standard practices used to verify that an anomaly is real, gauge its scope, and decide whether to escalate. Activating recovery sites and restoring data belong to the recovery portion of the Eradication and Recovery phase. Preparing a lessons-learned report occurs during Post-Incident Activity, and removing malware is an Eradication task-neither are tied to Detection and Analysis.
