For additional information, see the Schneider Electric security notice SEVD-2019-045-01. (https://download.schneider-electric.com/files?p_Doc_Ref=SEVD-2019-045-01) Schneider Electric strongly recommends following industry cybersecurity best practices, such as: * Physical controls should be in place so no unauthorized person would have access to the ICS and safety controllers, peripheral equipment, or the ICS and safety networks. * All controllers should reside in locked cabinets and never be left in the “Program” mode. * All programming software should be kept in locked cabinets and should never be connected to any network other than the network for the devices it is intended. * All methods of mobile data exchange with the isolated network (e.g., CDs, USB drives, etc.) should be scanned before use in terminals or any node connected to these networks. * Laptops that have connected to any other network besides the intended network should never be allowed to connect to the safety or control networks without proper sanitation.
