Incident Response: The First 72 Hours Checklist

A phase-by-phase checklist for the first three days after you discover a cyber incident: what to do in the first hour, how to scope and contain, who to notify, and what to put in place before it happens.

What's inside

  • Hour 0–1: stop, assemble the team and preserve evidence
  • Hours 1–24: scope, contain, reset credentials and bring in counsel and your insurer
  • Hours 24–72: eradication planning, notification obligations and communications
  • Preparation items to complete before an incident happens
