• IPsec is disabled by default in the Allen-Bradley Stratix 5950 devices.
• Rockwell Automation recommends that users not use any IPsec virtual private network (VPN) connections
• LAN-to-LAN IPsec VPN
• Remote-access VPN using the IPsec VPN client
• Layer 2 tunneling protocol (L2TP)-over-IPsec VPN connections
• Utilize proper network infrastructure controls, such as firewalls, to help ensure that requests from unauthorized sources are blocked and the controls are isolated from the business network.
• Consult the product documentation for specific features, such as access control lists and deep pack inspection, which may be used to block unauthorized changes, etc.
• 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, UTM devices, or other security appliances. For more information on TCP/UDP ports used by Rockwell Automation Products, see Knowledgebase Article ID 898270.
• Minimize network exposure for all control system devices and/or systems and ensure that they are not accessible from the Internet
