Cyberattack Backup: Safeguarding Essential Operations

Focus: Maritime Safeguarding (ports, terminals, shipyards)

At a modern port, every minute of downtime ripples across vessels, yard equipment, truck gates, and rail. A ransomware lockout of a crane HMI or Terminal Operating System (TOS) can halt discharging, strand containers, and trigger penalties. The answer isn’t only better prevention—it’s a backup-and-recovery design that brings safe operations back in minutes.

Why maritime operations are uniquely exposed

• Distributed critical assets: STS/RTG cranes, yard tractors, reefers, weighbridges, gates, VTS, and port security—often on mixed networks and legacy OS.
• Tight process coupling: If TOS, access control, or radio handheld services fail, cranes and gates quickly stall.
• Challenging environments: Harsh conditions and remote quay locations complicate on-site rebuilds.
• High consequence: Vessel delays, berth conflicts, demurrage, and safety risk at the quay.

Recovery objective: minutes, not days

Design for:

• Tiered restoration that prioritizes crane control and gate throughput.
• Image-level restores for HMIs/servers to avoid lengthy rebuilds.
• Immutable + offline copies resistant to ransomware and wipers.
• Portable recovery at the quay when the production network is quarantined.
• Evidence & drills that satisfy security and maritime compliance expectations.

Field rule: 3-2-1-1-0 — three copies, two media, one offsite, one immutable/offline, and zero errors in test restores.

Reference architecture (maritime-ready)

1) Production ➜ Vault (hot ➜ warm)

• Frequent, application-consistent snapshots for TOS, databases, license/identity.
• Image backups for crane HMIs, engineering workstations, and server VMs.
• One-way replication into a segmented vault with RBAC, MFA, delayed deletes, and tamper-evident logs.

2) Offline / air-gapped (cold)

• Rotated, fully offline copies with signed manifests to survive ransomware and insider threats.

3) Portable “dockside” recovery

• Rugged unit pre-loaded with golden images for common crane cabins, gate PCs, and yard workstations.
• One-click bare-metal restore to approved spares—even on a temporary, isolated switch at the berth.

Asset-specific guidance

• STS/RTG Cranes:
  Back up HMI images, PLC/drive configurations, network settings, and vendor toolchains. Target <15–30 min to reimage a crane console and validate interlocks.
• TOS & Yard Systems:
  Image + application-consistent backups for TOS, DBs, message brokers, and API gateways. Ensure quick failover or instant-recovery to restore job orchestration.
• Gates, Weighbridges, Access Control:
  Backup of workstation images, peripherals (badge/biometric/scale drivers), and policy databases. Restore gates early to keep truck flow moving.
• Network & Security Devices:
  Versioned exports of switch/router/firewall configs; keep a printed “last-known-good” for worst-case rebuilds.

Golden rule: restore control and flow first; analytics can wait.

Day-of-incident playbook (port-friendly)

1. Contain affected VLANs; preserve forensics.
2. Establish trust boundary: boot the portable unit; verify signed images.
3. Restore Tier 0 in an isolated enclave.
4. Bring back Tier 1: reimage crane HMIs and gate PCs; verify safety interlocks and peripherals.
5. Stabilize yard flow: coordinate manual worklists while TOS returns.
6. Restore Tier 2: TOS/DBs and integrations; rejoin segments gradually.
7. Harden: rotate credentials/keys; re-baseline golden images.
8. Debrief: capture actual RTO/RPO; update quay and gate runbooks.

60-day rollout

• Weeks 1–2 – Discover & prioritize: inventory cranes, gates, servers; define RPO/RTO by tier.
• Weeks 3–5 – Build: deploy segmented vault with immutability; create image + app-consistent jobs; script one-way replication; prep the dockside kit.
• Weeks 6–7 – Prove: live drill—restore one crane HMI and a gate PC; instant-recover a TOS instance; record evidence.
• Week 8 – Harden & handoff: enable MFA/four-eyes deletion; finalize offline rotation; laminate berth/gate run cards.

KPIs the harbor master cares about

• Crane console restore time (median minutes to HMI).
• Gate throughput recovery (time to reopen lanes).
• Immutability posture (days since last verified offline copy).
• Coverage (% of Tier-1 assets with current images/configs).
• Drill success rate and audit evidence freshness.

Where to go next

If your current plan still assumes “we’ll rebuild when the vessel sails,” it’s time to shift to minutes-class recovery for quay and gate operations. Start with a readiness assessment and a live restore drill. For solution patterns that make this practical, see a cyber resilience platform and options for cyber attack Recovery.

Bottom line: Ports win by restoring control and flow fast. With immutable backups, offline copies, and a dockside recovery kit, maritime operations can keep ships moving—even under cyber fire.
