Islandization with small firewalls
IT security for machines, devices and systems
Whether it’s a machine tool, x-ray machine or elevator control: much of this equipment is network-capable, but based on old and/or non-patchable operating systems. This makes them an easy target for attacking and represent a risk not only for their own sake but also for other network members. Small firewalls subdivide and segment these systems. They control, monitor and log communication using basic rules and thereby close many security gaps. Remote access, for example when service is required, is via a VPN, which is enabled as needed by the user.
