Rockwell Automation recommends upgrading to the latest version of FactoryTalk Alarms and Events, Version 2.90 or later, and applying available patches, which can be obtained at the following location:
FactoryTalk Alarm and Event history is logged using the Rockwell Alarm Historian service using Port 403, writing alarms and events to the user-configured SQL Server database. If the Rockwell Automation Alarm Historian service is on the same machine as the Rockwell Alarm Event service, then Port 403 can be blocked remotely as the historical information is being logged to the local host rather than a remote host. Any other machine in the system that does not have the Rockwell Alarm Historian service on the same machine as the Rockwell Alarm Event service will require access to Port 403. However, FactoryTalk View SE clients using the Alarm and Event Log Viewer to view FactoryTalk Alarm and Event history do not require Port 403, and can thus be blocked.
Rockwell Automation recommends that users who are unable to update and apply available patches should pursue risk mitigation strategies provided below. In addition, users are encouraged, when possible, to combine these strategies with the general security guidelines.
Block all traffic to EtherNet/IP or other CIP protocol-based devices from outside the Manufacturing Zone by blocking or restricting access to TCP and UDP Port 2222 and Port 44818 using proper network infrastructure controls (such as firewalls), Unified Threat Management (UTM) devices, or other security appliances.
