1. Purpose & Scope
-
Purpose: Define how to run the command channel, meeting cadence, action tracker, decision log, and status updates for a major security incident.
-
Scope: Applies to Sev 0 or major security incidents requiring cross-functional coordination, executive visibility, multiple technical workstreams, or extended response across teams and geographies.
2. Definitions
- War Room: Dedicated communication channel and meeting bridge used for real-time incident coordination.
- Action Tracker: Authoritative list of open actions, owners, priorities, due times, and status.
- Decision Log: Record of material decisions, approvers, rationale, timestamps, and follow-up actions.
- Operating Cadence: Agreed schedule for technical syncs, leadership updates, handoffs, and stakeholder briefings.
3. Roles & Responsibilities
- Incident Commander: Owns war room structure, cadence, priority setting, decision logging, and command transitions.
- Deputy Incident Commander: Maintains action tracker, follows up on blockers, and supports continuity during long-running incidents.
- Technical Lead: Coordinates technical workstreams and reports investigation, containment, and recovery status.
- Communications Lead: Coordinates approved stakeholder updates and ensures messaging aligns with Legal/Compliance.
- Scribe: Captures timeline, decisions, actions, owners, status updates, and evidence locations.
4. Procedure
4.1 Prerequisites
- Major incident declared or likely to be declared
- Incident Commander assigned
- Incident ticket created
- War room channel and meeting bridge available
- Initial severity, scope, and active workstreams identified
4.2 Step-by-Step Instructions
-
Open the War Room
- Create or activate the incident channel and meeting bridge.
- Pin links to the incident ticket, action tracker, decision log, evidence repository, and active playbooks.
- State the current Incident Commander, Technical Lead, Communications Lead, and Scribe.
-
Establish Operating Cadence
- Define cadence for:
- Technical syncs
- Executive updates
- Legal/communications reviews
- Geo handoffs
- Recovery checkpoints
- Publish the cadence in the war room.
- Define cadence for:
-
Create the Action Tracker
- Track each action with:
- Owner
- Priority
- Due time
- Status
- Blockers
- Link to evidence or ticket
- Review open actions at each technical sync.
- Track each action with:
-
Maintain the Decision Log
- Record material decisions including:
- Decision made
- Approver
- Rationale
- Timestamp
- Risks accepted
- Follow-up actions
- Record material decisions including:
-
Coordinate Workstreams
- Track workstreams such as investigation, containment, recovery, communications, legal, vendor, and customer support.
- Ensure each workstream has an owner and next update time.
- Escalate blockers to the Incident Commander.
-
Publish Status Updates
- Use concise updates covering:
- Current status
- Impact
- Actions completed
- Open risks
- Next milestones
- Decisions needed
- Do not include unapproved external messaging or sensitive details outside approved channels.
- Use concise updates covering:
-
Execute Command Handoffs
- Use the geo handoff SOP when command changes across shifts or regions.
- Confirm the incoming Incident Commander accepts command in the war room and incident ticket.
-
Close or Downgrade the War Room
- Confirm containment, recovery status, communications status, and open follow-up items.
- Downgrade or close the war room only with Incident Commander approval.
- Preserve the action tracker, decision log, and timeline in the incident record.
5. Compliance & Auditability
- War room actions, decisions, command changes, and status updates must be retained in the incident record.
- Decision logs must include approver, rationale, timestamp, and follow-up owner.
- External communications must follow approved legal and communications processes.
- This SOP's execution is reviewed during the Post-Incident Review.
6. Communication & Escalation
-
Internal Communication:
- War room is the primary coordination channel for the major incident.
- Executive and stakeholder updates follow the cadence approved by the Incident Commander and Communications Lead.
-
Escalation Criteria:
Condition Action Workstream blocked Escalate to Incident Commander and workstream owner Decision required from leadership Add to decision log and escalate to executive sponsor Legal or external communication required Engage SOP-003 process Vendor support required Engage SOP-005 process Shift or geo transition required Engage SOP-002 process
