Disaster Recovery Plan Cyber Security Example

Standard Operating Procedure: Cybersecurity Disaster Recovery Plan Execution

---

1. Executive Summary & Purpose

This Standard Operating Procedure (SOP) defines the operational directives for executing the Cybersecurity Disaster Recovery Plan (CDRP) at Template Registry. The objective is to establish a deterministic, repeatable workflow for containing cyber security incidents, isolating compromised infrastructure, executing forensic preservation, and restoring core registry operations from immutable, air-gapped backups. Compliance with this SOP is mandatory during declared cyber-related Priority 1 (P1) incidents.

2. Scope & Prerequisites

Scope

This procedure applies to all cloud-native infrastructure, on-premises core switching fabrics, database clusters, and artifact storage repositories managed by Template Registry.

Prerequisites & Required Access

• Identity & Access Management: Multi-Factor Authentication (MFA) token with elevated break-glass administrative privileges via Privileged Access Management (PAM) vault.
• Hardware/Software Tools:
  • Terminal access with kubectl, Terraform, AWS/GCP CLI v2, and Ansible installed.
  • Forensic analysis workstation loaded with Volatility 3, Autopsy, and Wireshark.
  • Secure out-of-band communication channel (Signal Enterprise / dedicated PagerDuty bridge).
• Physical/PPE: Secure isolated hardware tokens (YubiKey 5 FIPS) for master cryptographic key decryption.

4. Step-by-Step Procedure

Phase 1: Incident Declaration, Triage, and Network Isolation

• 1.1 Acknowledge P1 security alert via PagerDuty and open the unified bridge within 5 minutes of automated trigger.
• 1.2 Formally declare a cybersecurity disaster event by executing the break-glass script:

  ./scripts/sec-ops/declare-dr-event.sh --auth-token $PAM_TOKEN --severity P1-CRITICAL
  

• 1.3 Execute network quarantine protocol to sever inbound/outbound external communication while preserving internal telemetry pipelines:

  terraform apply -target=module.edge_firewall -var="quarantine_mode=true"
  

• 1.4 Revoke all active API tokens, user sessions, and service principal credentials globally across the identity provider (IdP).

Phase 2: Forensic Preservation and Evidence Collection

• 2.1 Capture non-volatile storage state by creating immediate, read-only snapshots of all attached Amazon EBS / persistent disk volumes for analysis.
• 2.2 Isolate volatile memory (RAM) from compromised container nodes or virtual machines prior to power-down:

  liME-capture-tool --output /mnt/forensic-vault/ram_dump_$(hostname).lime
  

• 2.3 Export all centralized SIEM and access logs (Datadog/Splunk) matching a 72-hour lookback window into cold S3 forensic buckets.
• 2.4 Compute and record cryptographic hashes (SHA-256) of all preserved system images to ensure chain of custody integrity.

Phase 3: Environment Destruction and Clean Infrastructure Provisioning

• 3.1 Destroy compromised Kubernetes clusters, container registries, and application nodes utilizing Infrastructure as Code (IaC):

  terraform destroy -auto-approve -var-file="prod.tfvars"
  

• 3.2 Provision a completely fresh, isolated Virtual Private Cloud (VPC) baseline utilizing verified, clean Terraform templates.
• 3.3 Validate the integrity of the new infrastructure perimeter by executing automated security posture scans against the fresh network topologies.

Phase 4: Data Restoration from Immutable Backups

• 4.1 Verify the cryptographic checksums of the designated golden backup point within the air-gapped, immutable vault.
• 4.2 Initialize the primary database restoration pipeline using Point-In-Time Recovery (PITR) to a transaction boundary immediately preceding the intrusion:

  pg_restore --clean --if-exists --dbname=$NEW_DB_URI /vault/backups/registry_pitr_target.dump
  

• 4.3 Rehydrate object storage buckets (Template artifacts) utilizing cryptographically verified object-lock-enabled AWS S3 snapshots.
• 4.4 Run database integrity validation checks and checksum matching scripts to ensure zero data corruption occurred during restoration.

Phase 5: Verification, Monitoring, and Controlled Re-entry

• 5.1 Execute automated end-to-end integration and smoke tests against the restored staging environment:

  pytest --environment=disaster-recovery-validation --tb=short
  

• 5.2 Enable application routing step-by-step using a canary deployment strategy (5% -> 25% -> 100% traffic shift).
• 5.3 Monitor error rates, latency metrics, and CPU usage profiles via the real-time observability dashboard for a mandatory 60-minute soak period.
• 5.4 Issue an all-clear notification to the Executive Leadership Team and transition operations back to standard on-call rotations.

5. Quality Assurance & Pro-Tips

Best Practices

• Never Mount Compromised Volumes: Do not attempt to mount suspected storage volumes directly to clean operational hosts; always use isolated forensic sandboxes.
• Immutable Storage Verification: Ensure backup vaults enforce Write-Once-Read-Many (WORM) policies to prevent malicious privilege escalation paths from wiping historical recovery points.

Common Pitfalls to Avoid

• Pitfall: Failing to revoke service-to-service mTLS certificates alongside user tokens. Correction: Ensure the IdP rotation script systematically targets internal service accounts.
• Pitfall: Restoring data without prior forensic capture, destroying evidence of entry vectors. Correction: Enforce Phase 2 completion checks before executing Phase 3.

Metric Thresholds

• Recovery Time Objective (RTO): $\le 4$ hours from declaration to traffic re-entry.
• Recovery Point Objective (RPO): $\le 15$ minutes of maximum data loss via PITR backups.

6. Frequently Asked Questions (FAQ)

Q1: What should we do if the immutable backup vault yields checksum validation errors during Phase 4?
A: Immediately halt the restoration process for that specific partition. Fall back to the next incremental backup timestamp within the rotational chain (typically $N-1$ hour). Escalate the integrity failure to the Chief Architect and storage reliability engineering leads immediately.

Q2: Can we bypass the 60-minute soak period in Phase 5 if business stakeholders demand faster resumption?
A: No. Bypassing the soak period violates Template Registry institutional governance policies. The Incident Response Commander holds direct accountability for enforcing stability validation windows to prevent secondary reinfection.
