Use EcoStruxure™ Operator Terminal Expert and Pro-face BLUE software only on atrusted workstation.
Harden your workstation following the best cybersecurity practices (antivirus, updatedoperating systems, strong password policies, application whitelisting software, etc.)
using the Schneider Electric Recommended Cybersecurity Best Practices document.

General Security Recommendations
We strongly recommend the following industry cybersecurity best practices.
•••
•
•
•
•
•

Locate control and safety system networks and remote devices behind firewalls andisolate them from the business network.
Install physical controls so no unauthorized personnel can access your 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 network intended forthat device.
Scan all methods of mobile data exchange with the isolated network such as CDs, USB
drives, etc. before use in the terminals or any node connected to these networks.
Never allow mobile devices that have connected to any other network besides theintended network to connect to the safety or control networks without proper sanitation.
Minimize network exposure for all control system devices and systems and ensure thatthey 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 themost current version available. Also, understand that VPNs are only as secure as theconnected devices.

For more information refer to the Schneider Electric Recommended Cybersecurity Best
Practices document.
