Islandization with small firewalls

IT security for machines, devices and systems

Little men in rain made of strings

Whether it’s a machine tool, X-ray machine or lift controller: many of these devices are network capable but based on antiquated and/or non-patchable operating systems. This makes them an easy target, representing a risk not only in themselves but also for other network devices. Micro firewalls isolate and segment these systems. They control, monitor and log communication using IP- and port-based rules to close many security gaps. Remote access, such as when service is needed, is option via a VPN which is enabled by the user as required.
