07 Remediation
Harden the configuration Who should apply this recommendation: All users To reduce the risk of exploitation, ARC Informatique strongly recommends implementing the following defensive measures: * Minimize network exposure for all control system devices and/or systems, and ensure they are not accessible from insecure networks. * Locate control system networks and remote devices behind firewalls and isolate them from business networks. * 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. Also recognize VPN is only as secure as its connected devices. Uninstall the Web Server Who should apply this recommendation: All users not using the affected component If your system does not require the use of the Web & Mobile features, you should make sure not to install them. If your system requires the use of the Web & Mobile features, they should be installed only on the Web Server. See the product help related to the installation for more information. Update IIS configuration – manually update HTTP headers Who should apply this recommendation: All users running affected components. As a quick mitigation for the unnecessary and missing HTTP headers, you can disable default headers and add secure HTTP headers for all requests. Those options can be set via the web.config file located on the IIS by following those steps: * Open the file
