Playbook: document incident response

In this article

Activate an initial scope and a case custodian

The first step is not to search everywhere. It is to bound what happened, what time period matters, and who coordinates evidence, access, and decisions. Without a case custodian, every team moves documents with good intent and poor traceability.

Preserve evidence before summarizing it

Capture logs, emails, document versions, tickets, and relevant artifacts before producing executive summaries. The narrative can be refined later. The original evidence, if lost or altered, does not come back.

Freeze critical sources and record preservation date.
Separate original evidence from working notes.
Control who accesses it and which copies are created.

Sort findings into fact, hypothesis, and pending

Mixing confirmed points with inferences degrades the response. Every working record should say what is proven, what is suspected, and what question remains open. That order protects both legal and technical coordination.

Limit communication to authorized routes

In document incidents, a bad message can worsen the problem as much as bad containment. Define who informs whom and at what level of detail. The rest of the team needs to work, not improvise messages.

Close with a document control lesson

After the incident, the learning should translate into retention, classification, access, or search changes. If closure only produces a report and not a new control, the organization will pay twice for the same mistake.
