Why TMS and WMS Security Is Critical
TMS (Transport Management System) manages transport planning, execution, and billing. It stores data about customers, cargo, routes, drivers, and subcontractors.
WMS (Warehouse Management System) controls warehouse operations — receiving, storage, picking, shipping. It manages data about inventory, locations, and orders.
Compromise of these systems means:
- Operational paralysis — inability to plan and execute transports/warehouse operations
- Data breach — customer data, rates, volumes, delivery addresses
- Data manipulation — falsifying delivery statuses, redirecting cargo
- Financial losses — operational downtime costs logistics companies EUR 5,000-50,000/hour
In 2025, ransomware attacks on TMS/WMS systems accounted for 31% of all cyber incidents in logistics.
TMS/WMS Security Architecture
Network segmentation:
- TMS/WMS in a dedicated network zone (VLAN/subnet)
- Firewall between the TMS/WMS zone and the office network
- Separate DMZ zone for external partner integrations
- Microsegmentation: TMS, WMS, EDI, telematics in separate segments
- ZTNA for remote access (instead of site-to-site VPN)
Access control:
- MFA on all TMS/WMS user accounts
- RBAC with minimal permissions (dispatcher does not need access to billing)
- Service accounts with separate credentials per integration
- Regular permission reviews (quarterly)
- Automatic disabling of inactive accounts (90 days)
Encryption:
- TMS/WMS database encrypted at rest
- TLS 1.2+ for all connections
- EDI and API transmission encryption with partners
- Backup encryption
Securing Partner Integrations
Logistics companies integrate TMS/WMS with dozens of partners — this is the largest attack surface:
EDI (Electronic Data Interchange):
- Separate accounts and keys per partner
- EDI message schema validation (rejecting invalid formats)
- Anomaly monitoring: unusual volumes, new message types, off-hours transmissions
- AS2/SFTP encryption
API:
- OAuth 2.0 with short-lived tokens
- Rate limiting per partner
- Schema validation (OpenAPI/JSON Schema)
- API Gateway with logging and monitoring
VPN/Connectivity:
- ZTNA instead of full-tunnel VPN
- Segmentation — partner has access only to their data
- Traffic monitoring from partner networks
- Kill switch — ability to immediately disconnect a partner
Procedures:
- SLA agreements with security requirements
- Right to security audit of the partner
- Partner onboarding/offboarding procedures
- Regular certificate and key verification
Ransomware Protection
Ransomware is the most dangerous threat to TMS/WMS. Protection plan:
Prevention:
- EDR (Endpoint Detection and Response) on TMS/WMS servers
- Email security (phishing is the most common vector)
- Segmentation — ransomware from the office network cannot reach TMS/WMS
- Regular updates and patching
Backup:
- 3-2-1 rule (3 copies, 2 media, 1 off-site)
- Network-isolated backup (air-gapped or immutable storage)
- Regular recovery testing (monthly)
- Defined and tested RTO/RPO
Response:
- Ransomware response plan (who decides, who acts)
- SOC with behavioral ransomware detection
- Infected system isolation procedure
- Contacts for CERT, forensics firm, lawyers
TMS/WMS Security Monitoring and Auditing
Logging:
- All logins and administrative operations
- Critical data changes (rates, routes, driver assignments)
- Bulk operations (data export, bulk edit)
- Access to personal data (GDPR Art. 30)
Monitoring:
- 24/7 security monitoring with anomaly alerts
- Alerts: off-hours logins, mass data export, configuration changes
- Event correlation from multiple sources (SIEM)
- Security dashboard for management
Auditing:
- Annual TMS/WMS security audit
- Penetration testing of web interfaces and APIs
- Database configuration review
- Permission and segmentation verification
