Data Incident Response Plan Template

STANDARD OPERATING PROCEDURE: Data Incident Response Plan (DIRP)

Template Registry Engineering & Information Security

1. Document Control Block

2. Executive Summary & Purpose

2.1 Purpose

This Standard Operating Procedure (SOP) defines the institutional framework and chronological workflow for identifying, containing, eradicating, and recovering from data security incidents within the Template Registry infrastructure. Compliance with this SOP is mandatory for all engineering, operations, and incident response personnel to ensure regulatory compliance (GDPR, CCPA, SOC 2 Type II), minimize downtime, and preserve forensic integrity.

2.2 Objectives

• Standardize the triage and escalation lifecycle for data breaches, unauthorized access, and data corruption events.
• Maintain chain-of-custody for all digital forensics artifacts.
• Establish deterministic communication pathways for internal stakeholders, regulatory bodies, and affected tenants.

3. Scope & Prerequisites

3.1 Scope

This SOP applies to all production environments, staging environments, CI/CD pipelines, cloud infrastructure (AWS/GCP), localized administrative terminals, and third-party data processors connected to the Template Registry ecosystem.

3.2 Prerequisites & Tooling Access

Personnel executing this SOP must possess active credentials and pre-configured access to the following systems:

• SIEM / Observability: Datadog / OpenSearch Security Dashboards.
• Incident Management: PagerDuty (On-Call Rotation) & Jira Enterprise Service Desk.
• Forensics / Containment: AWS Console / GCP IAM, HashiCorp Vault, Kubernetes CLI (kubectl).
• Secure Communications: Signal Enterprise / PGP-encrypted out-of-band communication channels.
• PPE: Not applicable (Digital-only infrastructure operations).

5. Step-by-Step Procedure

Phase 1: Identification & Triage

• 1.1 Acknowledge incoming automated alert from SIEM/IDS or manual ticket via PagerDuty within 5 minutes of paging.
• 1.2 Open the designated incident War Room (Bridge) via corporate encrypted video conferencing and secondary chat channel (#inc-YYYYMMDD-[name]).
• 1.3 Assign the Incident Commander (IC) and Lead Security Engineer (LSE) roles in Jira.
• 1.4 Assess initial severity classification based on data volume, sensitivity, and system impact:
  • Sev-1 (Critical): Exfiltration or corruption of PII, financial records, or core multi-tenant DB compromise.
  • Sev-2 (Major): Isolated service compromise without direct data loss confirmation.
  • Sev-3 (Moderate): Policy violation or reconnaissance activity detected.
• 1.5 Log all initial telemetry timestamps, anomalous IP addresses, and affected resource IDs in the Master Incident Timeline.

Phase 2: Containment

• 2.1 Execute short-term containment protocols based on vector analysis:
  • Network Vector: Isolate compromised VPC security groups or apply ingress/egress drops via NACLs.
  • Credential Vector: Revoke all active sessions and rotate API keys/tokens for compromised IAM roles using HashiCorp Vault.
  • Application Vector: Scale down affected Kubernetes deployments (kubectl scale deployment --replicas=0) to preserve memory states.
• 2.2 Preserve forensic integrity by initiating snapshot captures of affected EBS volumes, container memory dumps, and relevant access logs before executing destructive mitigation.
• 2.3 Verify containment efficacy via secondary monitoring tools to ensure lateral movement is halted.

Phase 3: Eradication & Remediation

• 3.1 Identify the root vulnerability (e.g., CVE, misconfigured S3 bucket, compromised service account).
• 3.2 Patch the underlying vulnerability or rollback the application deployment to a known clean git commit SHA.
• 3.3 Scan repositories and container registries for secondary persistence mechanisms (backdoors, unauthorized SSH keys, malicious cron jobs).
• 3.4 Rotate all system secrets, database credentials, and internal TLS certificates touched during the blast radius.

Phase 4: Recovery & Validation

• 4.1 Restore data integrity from verified immutable, offline backups if data corruption or ransomware is confirmed.
• 4.2 Incrementally bring services back online behind a Web Application Firewall (WAF) or restricted proxy.
• 4.3 Execute comprehensive integration and security regression test suites.
• 4.4 Monitor error budgets, database IOPS, and latency metrics for 120 continuous minutes to confirm stabilization.
• 4.5 Formally declare "Incident Resolved" to internal stakeholders.

Phase 5: Post-Incident Review (PIR)

• 5.1 Schedule the Blameless Post-Mortem meeting within 72 hours of incident closure.
• 5.2 Compile the definitive timeline, root cause analysis (RCA), and impact metrics.
• 5.3 Create actionable engineering tickets in Jira for preventative controls with strict SLA due dates.
• 5.4 Archive all forensic artifacts, chat transcripts, and audit logs into secure, long-term compliance storage.

6. Quality Assurance & Pro-Tips

6.1 Best Practices

• Preserve Evidence First: Never reboot a live compromised instance without first capturing a memory and disk snapshot; ephemeral data loss destroys forensic capability.
• Single Source of Truth: Direct all updates through the designated Jira ticket and incident channel. Avoid fragmented side-channels.
• Assume Breach Mindset: Treat every anomalous privilege escalation as an active persistent threat until proven otherwise.

6.2 Common Pitfalls to Avoid

• Premature Communication: Do not notify external entities or regulatory bodies before Legal and the Communications Officer have verified the factual scope of data exfiltration.
• Credential Reuse: Rotating keys without identifying how the initial key was compromised frequently leads to immediate re-compromise.

6.3 Metric Thresholds

• Mean Time to Acknowledge (MTTA): $\le 5\text{ minutes}$ (24/7/365).
• Mean Time to Contain (MTTC): $\le 30\text{ minutes}$ for Sev-1 incidents.
• Post-Mortem Completion SLA: $\le 72\text{ hours}$ post-resolution.

7. Frequently Asked Questions (FAQ)

Q: At what point must Legal Counsel and regulatory authorities be notified of a data incident?
A: Legal must be briefed immediately upon confirming that PII, financial data, or proprietary tenant IP has been accessed or exfiltrated by an unauthorized actor. Formal regulatory notification is dictated by statutory requirements (e.g., GDPR 72-hour notification window) and will be managed strictly through Legal Counsel.

Q: Who possesses the authority to shut down a core production database cluster during an active incident?
A: The Incident Commander (IC) holds the ultimate authority to sever production traffic or isolate databases, executed in coordination with the DevOps/SRE Lead to prevent catastrophic data loss.

Q: How should internal engineering teams handle inquiries from external media or customers during an active Sev-1 incident?
A: All inquiries must be redirected to the designated Communications Officer. Engineering personnel are strictly prohibited from commenting on social media, developer forums, or directly to customers regarding security incidents.
