    It is recommended to apply the following mitigations to reduce the risk of exploitation: • Set up an application password in the project properties • Set up network segmentation and implement a firewall to block all unauthorized access to port 502/TCP • Configure the Access Control List following the recommendations of the user manuals: https://www.se.com/ww/en/download/document/EIO0000001578/ • Set up a secure communication according to the following guideline “Modicon Controllers Platform Cyber Security Reference Manual,” in chapter “Setup secured communications”: https://www.se.com/ww/en/download/document/EIO0000001999/ NOTE: Use a BMENOC module and follow the instructions to configure IPSEC feature as described in the guideline “Modicon M580 - BMENOC03.1 Ethernet Communications Schneider Electric Security Notification Module, Installation and Configuration Guide” in the chapter “Configuring IPSEC communications”: https://www.se.com/ww/en/download/document/HRB62665/ OR • Use a BMENUA0100 module and follow the instructions to configure IPSEC feature as described in the chapter “Configuring the BMENUA0100 Cybersecurity Settings”: https://www.se.com/ww/en/download/document/PHA83350 OR • Consider using external firewall devices such as EAGLE40-07 from Belden to establish VPN connections for M340 and M580 architectures. For more details refer to the chapter “How to protect M580 and M340 architectures with EAGLE40 using VPN”: https://www.se.com/ww/en/download/document/EIO0000001999/ • Ensure the M580 CPU is running with the memory protection activated by configuring the input bit to a physical input, for more details refer to the following guideline “Modicon Controllers Platform Cyber Security Reference Manual”, “CPU Memory Protection section”: https://www.schneider-electric.com/en/download/document/EIO0000001999/ NOTE: The CPU memory protection cannot be configured with M580 Hot Standby CPUs. In such cases, use IPsec encrypted communication.
