** Rockwell Automation strongly recommends updating to signed firmware if possible. Once the module is updated to signed firmware (example 5.008 to 5.0029), it is not possible to revert to unsigned firmware versions.

Organizations should take the following actions to further secure ControlLogix communications modules from exploitation:

Update firmware. Update EN2* ControlLogix communications modules to firmware revision 11.004 and update EN4* ControlLogix communications modules to firmware revision 5.002. New firmware updates could also become available for other ControlLogix communication modules and organizations should update firmware as these updates become available.

Properly segment networks. Given a cyber actor would require network connectivity to the communication module to exploit the vulnerability, organizations should ensure ICS/SCADA networks are properly segmented within the process structure as well as from the Internet and other non-essential networks.

Implement detection signatures. Use appended Snort signatures to monitor and detect anomalous Common Industrial Protocol (CIP) packets to Rockwell Automation devices.
