Schneider Electric Security Notification
PowerLogic ION7400 / PM8000 / ION9000 Power Meters
9 May 2023 (13 June 2023)

Overview
Schneider Electric is aware of the use of an unsecure protocol in its PowerLogic ION9000,PowerLogic ION7400, PowerLogic PM8000, PowerLogic ION8650, PowerLogic ION8800 andall legacy ION products.
The PowerLogic ION9000, PowerLogic ION7400, PowerLogic PM8000, PowerLogic ION8650
and PowerLogic ION8800 are energy and power quality meters.
The ION Protocol was created over 30 years ago to bring sophisticated data exchange to digitalpower meters. As cybersecurity became a concern, the protocol was enhanced with support forauthentication. More recently, end-to-end encryption support for data in transit using industry
standard TLS was released after a multi-year effort to design a solution that would not breakbackward compatibility with decades of products installed in the field.
This disclosure announces the new secure ION protocol feature for the PowerLogic ION9000,
ION7400 and PM8000 products. Secure ION enhances the security of the ION protocol by usinga Transport Layer Security (TLS) encrypted tunnel between the device and other systems orsoftware.
June 2023 Update: Additional context has been added to the overview section.

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, 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.

Practices document.
