ICS-CERT and Rockwell Automation recommend that users take defensive measures to minimize the risk of exploitation of this vulnerability. Specifically, users should:

- Block all traffic to EtherNet/IP or other CIP protocol-based devices from outside the Manufacturing Zone by blocking or restricting access to Port 2222/TCP and UDP and Port 44818/TCP and UDP using proper network infrastructure controls, such as firewalls, UTM devices, or other security appliances. For more information on TCP/UDP ports used by Rockwell Automation Products, see Knowledgebase Article ID 898270 which is available at the following location:

https://rockwellautomation.custhelp.com/app/answers/detail/a_id/898270

- Minimize network exposure for all control system devices and/or systems, and help confirm that they are not accessible from the Internet.
- Locate control system networks and devices behind firewalls, and use best practices when isolating them from the business network. The Common Plant-wide Ethernet (CPwE) guide provides recommendations for deploying a plant-wide architecture: Industrial Firewalls within a CPwE Architecture
- When remote access is required, use secure methods, such as Virtual Private Networks (VPNs), recognizing that VPNs may have vulnerabilities and should be updated to the most current version available. Also recognize that VPN is only as secure as the connected devices.
