5.2. Incident Management Operations

💡 First Principle: Once an incident is declared, every operational decision trades speed against two things that matter just as much — evidence integrity and business continuity — and optimizing purely for speed routinely destroys one or both.

⚠️ Common Misconception: Containment is often assumed to mean immediately shutting down the affected system. Containment strategy must balance stopping the spread against preserving evidence and business continuity — premature shutdown can destroy volatile forensic evidence and cause unnecessary business disruption.

The five subsections that follow move through an incident roughly in chronological order — detecting and investigating with the right tools, containing and recovering the affected systems, communicating with stakeholders throughout, and reviewing afterward — but in practice several of these activities run in parallel under real time pressure, which is exactly why each one needs its own pre-defined discipline rather than being improvised in sequence during the incident itself.
