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.In order to operate the devices in a protected IT environment, Siemens recommends configuring the environment according to Siemens’ operational guidelines for industrial security and to following the recommendations in the product manuals.Īdditional information on Industrial Security by Siemens can be found at: įor more information about this issue, please see Siemens Security Advisory SSA-549234ĬISA recommends users take defensive measures to minimize the risk of exploitation of this vulnerability. Siemens recommends affected users limit access to Port 102/TCP to trusted users and systems only.Īs a general security measure, Siemens strongly recommends protecting network access to devices with appropriate mechanisms. Michael Messner from Siemens Energy reported this vulnerability to Siemens. A major highlight of the SIMATIC NET V12 is the enhanced support of virtual environments.
