The First 90 Seconds: How Early Decisions Impact Incident Response Success

The article examines failures in security incident response, emphasizing that they generally do not stem from a lack of tools, intelligence, or technical skills, but rather from decisions made immediately after threat detection. The author observes that incident response (IR) teams can recover from sophisticated intrusions even with limited telemetry, but can also lose control of investigations they should have been able to manage. The focus is on the critical period following detection, characterized by high pressure and incomplete information.
