1. Executive Summary & Purpose

This Standard Operating Procedure (SOP) establishes the mandatory protocol for activating, executing, and deactivating the Disaster Recovery Plan (DRP) for credit union core banking infrastructures, member-facing digital channels, and auxiliary data systems.

The purpose of this document is to ensure compliance with Federal Credit Union Act guidelines, NCUA regulations (Part 749), and FFIEC Business Continuity Planning standards. This SOP provides a deterministic operational pathway to achieve Recovery Time Objectives (RTO < 4 hours) and Recovery Point Objectives (RPO < 1 hour) during localized outages, cyber-incidents, or catastrophic facility loss.

2. Scope & Prerequisites

Scope

This procedure applies to all IT infrastructure, core processing integration layers (e.g., Fiserv, Jack Henry, Symitar), enterprise databases, secondary disaster recovery (DR) hot sites, and associated remote-access systems managed or contracted by Template Registry and client credit unions.

Prerequisites & Required Tools

• Authentication: Multi-Factor Authentication (MFA) tokens with out-of-band emergency override capability.
• Access Control: Privileged Access Management (PAM) vault check-out credentials for emergency break-glass accounts.
• Software Tooling:
  • Enterprise orchestration engine (e.g., VMware Site Recovery Manager / Zerto).
  • Out-of-band communication platform (e.g., encrypted satellite/cellular bridge).
  • SIEM & Infrastructure Monitoring (e.g., Datadog, Splunk).
• Physical Access: Biometric badge override and physical key access to alternate recovery bunkers or collocation facilities.

4. Step-by-Step Procedure

Phase 1: Incident Assessment & Plan Activation

• 1.1 Convene the Emergency Response Team (ERT) via the secure out-of-band conference bridge within 15 minutes of threshold alert.
• 1.2 Verify operational failure criteria (e.g., primary data center power loss exceeding 30 minutes, unmitigated ransomware deployment, or structural site compromise).
• 1.3 Incident Commander (IC) formally declares a disaster event and authorizes DRP execution, timestamping the event in the incident logging system.
• 1.4 Notify executive leadership and designated NCUA/state regulatory liaisons of plan activation via secure channel.

Phase 2: Secondary Site Initialization & Infrastructure Failover

• 2.1 Authenticate into the Enterprise Orchestration Engine using emergency break-glass administrative tokens.
• 2.2 Execute automated pre-flight checks on the secondary DR hot-site infrastructure (compute, storage, and networking layers).
• 2.3 Initiate the automated DNS TTL (Time-To-Live) reduction sequence across external-facing name servers to 60 seconds.
• 2.4 Trigger core processing replication failover script (run-dr-failover-v4.sh) to promote the replica storage arrays to primary status.
• 2.5 Validate network routing tables and ensure BGP (Border Gateway Protocol) routes are propagating correctly to the secondary ISP uplinks.

Phase 3: Database Recovery & Data Integrity Validation

• 3.1 Mount the latest consistent transactional logs from the primary site storage snapshots onto the secondary database cluster.
• 3.2 Execute point-in-time recovery (PITR) procedures up to the exact transaction boundary preceding the incident timestamp to satisfy RPO requirements.
• 3.3 Run automated checksum validation scripts to verify zero data corruption across core member ledger tables:

  psql -h dr-db-cluster -U sysadmin -d core_prod -f /opt/dr/scripts/verify_ledgers.sql
  

• 3.4 Confirm database transaction logs show active read-write consensus across all cluster nodes.

Phase 4: Application Integration & Member Channel Restoration

• 4.1 Boot application server clusters (API gateways, online banking nodes, mobile app backends) in the secondary environment.
• 4.2 Update Global Traffic Manager (GTM) / CDN routing targets to point member-facing ingress traffic to the DR environment.
• 4.3 Execute end-to-end synthetic transactions (ATM balance inquiry, ACH batch simulation, mobile login) to validate end-user functionality.
• 4.4 Release member-facing channels from maintenance mode once synthetic transaction success rate reaches 100% over a 5-minute sampling window.

Phase 5: Post-Failover Operations & Reporting

• 5.1 Transition operational monitoring from primary dashboards to secondary infrastructure telemetry feeds.
• 5.2 Establish an auxiliary incident command rotation schedule to manage 24/7 operations at the secondary site.
• 5.3 Compile the initial Incident Root Cause Analysis (RCA) data package for regulatory submission within 24 hours of stabilization.

5. Quality Assurance & Pro-Tips

Best Practices

• Immutable Backups: Ensure offsite storage repositories utilize WORM (Write Once, Read Many) technology to protect against ransomware secondary execution during a failover window.
• Bandwidth Throttling: Prioritize core processing replication traffic over non-essential log shipping during wide-area network constraints.

Common Pitfalls

• DNS Propagation Delays: Failing to reduce TTLs prior to an incident can trap users on unresolvable primary IP addresses for hours. Mitigation: Maintain continuous baseline TTL reductions on high-availability DNS records.
• Credential Desynchronization: Forgetting to sync IAM policies and service account passwords to the DR site causes microservice authentication failures. Mitigation: Run automated weekly secrets-vault synchronization audits.

Metric Thresholds

• RTO (Recovery Time Objective): $\le 4.0$ hours from disaster declaration to member channel restoration.
• RPO (Recovery Point Objective): $\le 1.0$ hour of potential transactional data loss.
• Synthetic Transaction Latency: $\le 800\text{ms}$ round-trip time for core banking API queries.

6. Frequently Asked Questions (FAQ)

Q1: What happens if the automated orchestration engine fails to promote the database cluster?
A: Fall back immediately to the manual CLI failover protocol. Access the storage array via out-of-band management interfaces, manually break storage replication pairs, promote the secondary LUNs to read-write mode, and execute the manual database recovery script (/opt/dr/scripts/manual_promote.sh). Escalate to the Lead Systems Engineer immediately.

Q2: How are credit union members informed during an active failover event?
A: The Communications Lead works in tandem with the executive team to push pre-approved templates via SMS, push notifications, and website banner updates. If digital channels are completely offline, out-of-band communication assets (such as emergency social media postings and designated phone tree recordings) are deployed.

Q3: When should the credit union initiate a fail-back sequence to the primary site?
A: A fail-back sequence must never be initiated during active business hours. It requires a stability verification window of at least 72 continuous hours at the DR site, full resolution of the primary site incident, and explicit sign-off from both the Incident Commander and the Compliance Officer.
