Basic Incident Response Plan Template

Standard Operating Procedure: Basic Incident Response Plan (IRP)

Document Control Block

1. Executive Summary & Purpose

This document establishes the institutional framework for detecting, analyzing, and mitigating security or operational incidents at Template Registry. The purpose is to minimize service degradation, maintain data integrity, and ensure systematic communication across stakeholders during high-pressure events.

2. Scope & Prerequisites

• Scope: All production systems, cloud infrastructure (AWS/GCP), and internal CI/CD pipelines.
• Required Tools: PagerDuty (Alerting), Slack/Teams (Crisis Channel), Jira/Linear (Tracking), Git (Audit trail).
• Prerequisites: All responders must possess active IAM credentials with "Incident Responder" permissions. No physical PPE required unless facility-level infrastructure failure occurs.

3. Roles & Responsibilities (RACI)

4. Step-by-Step Procedure

Phase I: Identification & Triage

• Verify incident trigger (Alert, user report, or system monitor).
• Categorize impact level: SEV-1 (Total outage), SEV-2 (Degraded), SEV-3 (Non-critical bug).
• Instantiate dedicated incident channel (e.g., #inc-YYYY-MM-DD-short-desc).

Phase II: Containment

• Isolate compromised instances or revoke affected API keys.
• Implement traffic shunting or load balancer redirection to prevent data corruption.
• Take snapshots/logs for forensic analysis before system state modification.

Phase III: Eradication & Recovery

• Identify root cause via log correlation and differential analysis.
• Execute remediating patch or roll back to last known good state.
• Verify integrity of the system post-fix.

Phase IV: Post-Incident Activity

• Restore normal operational traffic.
• Conduct Post-Mortem (Blameless) within 48 hours.
• Document lessons learned in the Template Registry knowledge base.

5. Quality Assurance & Pro-Tips

• Metric Thresholds: Mean Time to Acknowledge (MTTA) < 5 mins; Mean Time to Recovery (MTTR) < 60 mins.
• Pro-Tip (The "Golden Rule"): Never allow the Incident Commander to touch the keyboard. The IC coordinates strategy; the SME executes. Mixing these roles leads to cognitive tunnel vision.
• Pitfall: Avoid "Analysis Paralysis." If the cause is unknown, favor recovery (reboot/rollback) over deep investigation during active outages.

6. Frequently Asked Questions (FAQ)

Q: When should I escalate an incident to the Executive Team? A: Escalate immediately if the incident involves potential PII data exfiltration, regulatory breach, or if the projected MTTR exceeds 4 hours.

Q: How do I handle internal communication during an outage? A: All updates must be centralized in the incident channel. Do not reply to DMs. Use the [Status Update] prefix for major milestones to ensure visibility for stakeholders.

Q: What if the primary Incident Commander is unreachable? A: The most senior engineering lead on-call assumes the IC role by default. If no primary is identified, escalate to the Engineering Manager immediately.
