Recovery Procedures

Scenario: Single System Failure

  1. Identify root cause (hardware, software, configuration)
  2. Activate failover (if available)
  3. Restore system from backup or rebuild
  4. Apply configuration from Git repository
  5. Verify integrity before returning to production
  6. Enhance monitoring for 24 hours

Scenario: Ransomware

  1. Immediately: Isolate all affected systems from the network
  2. Determine scope of encryption
  3. Verify backup integrity (identify clean backups)
  4. Restore systems from verified backups
  5. Rotate all credentials
  6. Close attack vector before bringing systems back online

  2. Failover to secondary site (if available)
  3. Prioritized recovery by service category
  4. Activate customer communication
  5. Ensure provisional operations
  6. Complete recovery after primary site availability
