NIS2 for the metal & sheet metal sector
CNC machines, laser cutters, punch presses and welding robots run on Fanuc, Siemens and Beckhoff controllers. Many installations are directly connected to CAD/CAM servers, a direct attack vector that NIS2 addresses.
OT systems that fall under NIS2
What NIS2 means for your OT
NC program integrity
A manipulated CNC program can produce dimensional deviations that are only discovered in later production stages or by the customer, with liability risk.
DNC server as attack path
DNC servers distribute NC programs to machines. They are often connected to both the office network and machine engineering, without segmentation.
Robot safety functions
Safety functions of welding robots (safety scanner, emergency stop) are firmware-based. Older robots lack authentication on the service interface.
Three steps to NIS2 compliance
DNC segmentation
DNC server on separate VLAN, only reachable via controlled CAD/CAM interface. No direct connection to office email or internet.
NC program audit trail
Version control system for NC programs with access control, change history and hash verification when loading onto the machine.
Robot service hardening
Disabling unused service ports on robot controllers, role-based access and logging of login attempts on the teach pendant/service interface.
OT security and machine refit often go hand in hand. A refit to a modern PLC also improves your NIS2 posture.
