An incident audit trail is the record of who did what, when and from where, both during each incident and in the configuration of the tool that runs incidents. Software maintains it by logging events automatically instead of relying on people to write things down. Look for two records: an incident timeline that captures status changes, role assignments, messages, alerts and automated actions with a timestamp, actor and source, and an audit log of configuration changes with before-and-after values.
Manual notes break down under pressure, and a reconstructed timeline written days later is the first thing an auditor questions. This guide covers what each record should capture and how to keep one without extra work. For what SOC 2 auditors look for specifically, see audit-ready incident records.
What an incident audit trail should record
| Record | What it captures | Why it matters |
|---|---|---|
| Declaration | Who declared, when, from which alert or channel | Shows detection and response start times |
| Status and severity changes | Every transition with timestamp and actor | Proves escalation followed policy |
| Roles | Who was incident commander and when that changed | Shows ownership at each point |
| Messages and decisions | Key chat messages and notes captured as events | Explains why actions were taken |
| Automated actions | Workflow runs, pages sent, tickets created | Shows what the system did, not just people |
| Communications | Status page updates and stakeholder messages | Proves customers were informed |
| Follow-up | Retrospective and action items with owners | Shows the loop was closed |
| Configuration changes | Edits to severities, escalation policies, workflows, roles and integrations | Shows the process itself wasn’t changed without trace |
The incident timeline
The timeline is the record of one incident. In Rootly it collects human and system events in one chronological feed: status transitions, role assignments, Slack messages promoted to timeline events, email replies, attachments, alert updates and workflow actions. Each event records its text, who performed it, the timestamp and the source (Slack, web, email or API), and can be marked internal or external.
Responders add events from Slack without leaving the incident channel, star the entries that matter, and export the timeline for reports. Because the record builds itself during the response, the retrospective starts from facts rather than memory.
The configuration audit log
The audit log is the record of the system. Rootly’s Audit Log captures every create, update and delete across about 60 resource types: configuration, incidents and action items, workflows, integrations, on-call schedules, escalation policies and alert routes, and the service catalog. Each entry records the actor, the resource, the action, the source (web, API, mobile, Slack, SCIM or OAuth), the API key if one was used, the IP address when available, and the before-and-after value of every changed field.
Passwords, tokens and API keys are redacted. Access is role-based, and an on-call role can be limited to on-call changes only. Audit logs are retained indefinitely by default and can be pulled through the API for long-term archival. The Audit Log is part of Rootly’s Enterprise plan.
How to keep an audit trail without extra work
- Run incidents where events are captured. If the response happens in chat, the tool should capture chat activity into the timeline.
- Automate the routine steps. Workflows that declare, page, assign and update leave their own entries, so the record is complete even when responders are busy.
- Use consistent fields. Severity, services, environment and incident type on every incident make records comparable across a year of audits.
- Export on a schedule. Pull timelines and audit events into the archive your compliance team uses, rather than exporting by hand before each audit.
How Rootly keeps the record
Rootly builds the incident timeline automatically on every plan, from Slack, Microsoft Teams, Google Chat, email, the web app, the API and workflows. Enterprise adds the configuration Audit Log. Rootly is SOC 2 Type II certified and supports GDPR, CCPA and HIPAA requirements; details are on the security page.
Frequently asked questions
What software helps maintain an incident audit trail?
Incident management platforms that record two things automatically: a timeline of every event during each incident (status changes, role assignments, messages, alerts and actions, each with who, when and source), and an audit log of changes to the tool's own configuration, such as severities, escalation policies and workflows. Rootly keeps both: the incident timeline on every plan, and an Audit Log on the Enterprise plan.
What should an incident audit trail include?
For each incident: when it was declared, every status and severity change, who held each role, the messages and decisions that mattered, alerts and actions taken by automation, customer communications, and the retrospective with its action items. For the tool itself: who changed which setting, when, from where, and the before and after values.
What is the difference between an incident timeline and an audit log?
The timeline is the record of one incident: what happened, in order, during the response. The audit log is the record of the system: who created, changed or deleted configuration such as escalation policies, workflows, roles and integrations. Auditors usually want both.
Can an incident audit trail be edited?
Responders should be able to add context to an incident timeline, such as a note or a corrected timestamp, but configuration changes should only be recorded, never rewritten. In Rootly, the Audit Log records every create, update and delete with before-and-after values, and credentials are redacted.
How long should incident audit records be kept?
As long as your compliance framework and contracts require, which is often a year or more. Rootly retains audit logs indefinitely by default, and the API lets you pull them on a schedule into storage your auditors already use.
