In normal operation, the CAE software tool is connected to devices for a very limited time and isoffline most of the time. However, it is recommended that end-users of the Cybersecurity Admin
Expert tool do the following:•Refresh the device’s status before sending configuration to ensure the validity of thedevices certificate.

•Use proper network segmentation and closely monitor traffic for signs of malicious
activity when connected to devices•Check the status of the devices on the network

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.

Schneider Electric Security Notification••••

Scan all methods of mobile data exchange with the isolated network such as CDs, USBdrives, 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.
