Firewall voor industriële netwerken is een begrip binnen de industriële digitalisering en extra industrie & security topics.
Definitie
Firewall voor industriële netwerken is een gespecialiseerde beveiligingsapplicatie die netwerkverkeer filtert en controleert tussen verschillende zones in industriële omgevingen. Het beschermt kritieke productiesystemen door ongewenst verkeer te blokkeren terwijl legitieme communicatie tussen MES, ERP en IoT systemen wordt toegestaan.
Kenmerken
- Industrial protocol awareness: Deep packet inspection voor Modbus, DNP3, OPC UA, EtherNet/IP
- Zone-based security: Traffic control tussen DMZ, production, en enterprise zones
- Real-time performance: Low latency filtering voor time-critical industrial communications
- Stateful inspection: Connection tracking voor complex industrial protocols
- Application-layer filtering: Protocol-specific rule enforcement
- High availability: Redundant configurations voor continuous operation
- Industrial hardening: Environmental resistance, extended temperature ranges
- Centralized management: Policy management across multiple industrial firewalls
Toepassing
Purdue model implementation:
- Level 0-1 protection: Sensor en actuator network security
- Level 2 isolation: Control system protection from higher network levels
- Level 3-4 separation: Manufacturing systems isolation from enterprise networks
- DMZ implementation: Secure data exchange tussen OT en IT domains
Manufacturing network security:
- Production floor: Protection van CNC machines, welding robots
- Quality systems: SPC, quality analysis tools isolation
