Incident Response Plan Template Reddit

Standard Operating Procedure: Incident Response (IR) Lifecycle

Template Registry Engineering Standards

2. Executive Summary & Purpose

This document establishes the institutional framework for detecting, containing, and remediating service-impacting incidents at Template Registry. The purpose is to minimize Mean Time to Recovery (MTTR), preserve forensic integrity, and ensure systematic documentation of remediation efforts to prevent recurrence.

3. Scope & Prerequisites

• Scope: Applies to all production environments, CI/CD pipelines, and cloud infrastructure managed by Engineering.
• Required Tooling: Slack (Incident channel), PagerDuty (Alerting), Jira (Post-mortem tracking), Datadog/CloudWatch (Observability), GitHub (Audit trails).
• Prerequisites: All responders must possess active SSO/MFA credentials and VPN access.

5. Step-by-Step Procedure

Phase 1: Detection & Triage

• Verify incident severity (SEV1: Total outage, SEV2: Degraded, SEV3: Minor).
• Open dedicated Slack channel (e.g., #inc-YYYYMMDD-incident-name).
• Appoint Incident Commander (IC).

Phase 2: Containment

• Isolate compromised assets (e.g., disable traffic, revoke IAM roles).
• Implement hotfixes or rollback to last known stable state.
• Verify fix via telemetry (ensure metric stabilization for 15 minutes).

Phase 3: Eradication & Recovery

• Patch underlying vulnerabilities identified during triage.
• Execute full service restoration.
• Validate system integrity (run automated regression test suite).

Phase 4: Post-Incident Activity

• Conduct Blameless Post-Mortem within 48 hours.
• Document "Root Cause" and "Contributing Factors."
• Create follow-up Jira tickets for permanent remediation.

6. Quality Assurance & Pro-Tips

• Pro-Tip (Communication): Never update customers until the IC has vetted the message. Use pre-drafted status templates to save time.
• Pro-Tip (Tooling): If a fix takes > 30 minutes, switch to a rotation to prevent cognitive fatigue.
• Metric Thresholds:
  • MTTD (Mean Time to Detect): < 5 minutes.
  • MTTR (Mean Time to Recovery): < 60 minutes.
• Common Pitfalls: Attempting to "debug" in production without capturing forensic logs; failing to communicate status to stakeholders every 30 minutes.

7. Frequently Asked Questions

Q: At what point should I escalate to an executive stakeholder? A: Escalate immediately if the incident involves customer data exfiltration, prolonged downtime exceeding 60 minutes, or potential regulatory/legal exposure.

Q: Should I fix the code during an incident if the root cause isn't fully understood? A: No. Focus on containment (e.g., traffic shedding or rollback) first. Avoid "blindly patching" while live, as it often compounds the original issue.

Q: What defines a "Blameless" post-mortem? A: Focus exclusively on systemic failures and process gaps. Never cite individual human error as a root cause; if a person made a mistake, the process allowed that mistake to be possible.
