Republished vendor advisory. This CISA CSAF advisory was converted from Schneider Electric CPCERT's CSAF advisory.
General Security Recommendations: We strongly recommend the following industry cybersecurity best practices. https://www.se.com/us/en/download/document/7EN52-0390/ * Locate control and safety system networks and remote devices behind firewalls and isolate 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 for that 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 the intended network to connect to the safety or control networks without proper sanitation. * Minimize network exposure for all control system devices and systems and ensure that 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. For more information refer to the Schneider Electric Recommended Cybersecurity Best Practices document.
