07 Remediation
Rockwell recommends the following: * Rockwell Automation strongly encourages users to apply the latest available version of firmware to keep up to date with the latest features, anomaly fixes, and security improvements. Update to a version of firmware as listed below that mitigates the associated risk: * Apply FRN 31.011 or later from: https://compatibility.rockwellautomation.com/Pages/MultiProductDownload.aspx?Keyword=5370&crumb=112 https://compatibility.rockwellautomation.com/Pages/MultiProductDownload.aspx * For EtherNet/IP-based vulnerabilities (ID 1-14), block all traffic to and from outside the Manufacturing Zone by blocking or restricting access to Port 2222/TCP/UDP and Port 44818/TCP/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 https://rockwellautomation.custhelp.com/app/answers/detail/a_id/898270/page/1 (login required). * Stratix users can use Device Manager or Studio 5000 Logix Designer to configure access control lists (ACL) to block/restrict ports. See section “Access Control Lists” in Stratix Managed Switches User Manual, publication 1783-UM007 http://literature.rockwellautomation.com/idc/groups/literature/documents/um/1783-um007_-en-p.pdf , for detailed instructions. * For web-based vulnerabilities (ID 15-17), block all traffic from outside the Manufacturing Zone by blocking or
