Incident Response Plan Template WORD

Standard Operating Procedure: Incident Response Plan (IRP)

1. Executive Summary & Purpose

This document establishes the institutional framework for identifying, containing, eradicating, and recovering from security incidents at Template Registry. The purpose is to minimize operational downtime, preserve data integrity, and ensure regulatory compliance through a standardized, repeatable response lifecycle.

2. Scope & Prerequisites

• Scope: All digital assets, cloud environments, and physical infrastructure managed by Template Registry.
• Tools Required: Jira Service Management (Incident Project), PagerDuty (Alerting), Slack (Communication Bridge), Splunk/ELK (Log Analysis).
• Access Requirements: Admin-level access to Cloud IAM, VPN logs, and isolated sandbox environments.

3. Roles & Responsibilities (RACI Matrix)

4. Step-by-Step Procedure

Phase I: Detection & Analysis

• Verify anomalous alert via SIEM/Log aggregator.
• Assess severity level (Low, Medium, High, Critical).
• Establish communication bridge (Dedicated Slack channel: #incident-[id]).

Phase II: Containment

• Isolate affected network segments or cloud instances.
• Disable compromised credentials/API keys.
• Capture memory dumps/forensic snapshots before system termination.

Phase III: Eradication

• Identify root cause (e.g., malware, unauthorized access, misconfiguration).
• Remove malicious artifacts/patches vulnerabilities.
• Reset all administrative credentials across affected scope.

Phase IV: Recovery

• Restore services from the last known-good backup.
• Perform integrity checks/security hardening validation.
• Monitor logs for post-incident re-entry patterns.

Phase V: Post-Incident Activity

• Schedule "Lessons Learned" meeting within 72 hours.
• Update Incident Registry in Jira.
• Submit final After-Action Report (AAR) to Executive Leadership.

5. Quality Assurance & Pro-Tips

• Pro-Tip 1: Always assume compromised internal networks; treat all lateral movement as a high-severity threat.
• Pro-Tip 2: Keep a physical "Break-Glass" account documented in an offline safe.
• Metric Threshold: Mean Time to Acknowledge (MTTA) should be < 15 minutes; Mean Time to Containment (MTTC) should be < 2 hours for critical threats.
• Common Pitfall: Failing to preserve forensic evidence before performing a hard reboot. Always snapshot before restart.

6. Frequently Asked Questions

Q: At what point do I involve Legal/Compliance? A: Immediately upon confirmation of a breach involving PII, PHI, or PCI data. Do not wait for complete containment to initiate the legal notification workflow.

Q: Should I delete the compromised VM after recovery? A: Never delete a compromised VM until the forensic image has been verified and signed off by the Security Analyst. Keep it in an isolated VPC for a minimum of 30 days.
