Also recognize that VPN is only as secure as the 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 that 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. #Simatic net pc software update manuals#
