  • Locate control system networks and remote devices behind firewalls and isolate them from the business network.
  • Minimize network exposure for all control system devices and/or systems, use IP filter functions to allow only specific personal computer/device to connect, and ensure they are not accessible from the Internet.
  • To prevent unauthorized devices from being connected to the free ports of the HUB, use a LAN port lock to close the free ports.
