Also recognize VPN is only as secure as its connected devices.ĬISA reminds organizations to perform proper impact analysis and risk assessment prior to deploying defensive measures.ĬISA also provides a section for control systems security recommended practices on the ICS webpage on.
When remote access is required, use secure methods, such as Virtual Private Networks (VPNs), recognizing VPNs may have vulnerabilities and should be updated to the most current version available. Locate control system networks and remote devices behind firewalls, and isolate them from the business network. Minimize network exposure for all control system devices and/or systems, and ensure that they are not accessible from the Internet. Siemens simatic his update#
Update the entire solution to TIA Portal v17 and use TLS communication using individual certificates between PLC, HMIs, and PG/PCįor more information about this vulnerability and the associated mitigations, please see SSA-434534ĬISA recommends users take defensive measures to minimize the risk of exploitation of this vulnerability. System integrity: Configure, maintain, and protect devices by applying applicable compensating controls and using built-in security capabilities. Network security: Ensure PLC systems are not connected to untrusted networks. Plant security: Ensure physical prevention of access to critical components. Apply “defense in depth” as outlined on pages 12ff of the operational guidelines for industrial security, especially:. 
Use the display to configure additional access protection of the S7-1500 CPU (This blocks remote client connections, even when the client can provide the correct password). Disallow client connections via the ENDIS_PW instruction of the S7-1200 or S7-1500 CPU (This blocks remote client connections, even when the client can provide the correct password).
