Schneider Electric strongly recommends adhering to the following industry cybersecurity best practices:
- Locate control and safety system networks and remote devices behind firewalls and isolate them from the business network.
- Install physical controls to prevent unauthorized personnel from accessing industrial control and safety systems, components, peripheral equipment, and networks.
- Place all controllers in locked cabinets and never leave them in the "Program" mode.
- Never connect programming software to any network other than the one intended for that device.
- Scan all methods of mobile data exchange with the isolated network, such as CDs, USB drives, etc., before use in terminals or any nodes connected to these networks.
- Never allow mobile devices that have connected to any network other than the intended network to connect to safety or control networks without proper sanitation.
- Minimize network exposure for all control system devices and systems, ensuring they are not accessible from the Internet.
- When remote access is required, use secure methods such as Virtual Private Networks (VPNs). Recognize that VPNs may have vulnerabilities and should be updated to the most current version available. Also, understand that VPNs are only as secure as the connected devices.
