For more information see the associated Schneider Electric security advisory Modicon Controllers – SEVD-2019-134-11 PDF Version, Modicon Controllers – SEVD-2019-134-11 CSAF Version.
Schneider Electric strongly recommends 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 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 for the devices that it is intended.
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 laptops 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 see the associated Schneider Electric security advisory Modicon Controllers – SEVD-2019-134-11 PDF Version, Modicon Controllers – SEVD-2019-134-11 CSAF Version.

Schneider Electric strongly recommends 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 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 for the devices that it is intended.
• 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 laptops 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.

CISA recommends users take defensive measures to minimize the risk of exploitation of these vulnerabilities. CISA reminds organizations to perform proper impact analysis and risk assessment prior to deploying defensive measures.
