NCCIC/ICS-CERT recommends that users take defensive measures to minimize the
risk of exploitation of this vulnerability. Specifically, users should:
- -Minimize network exposure for all control system devices and/or systems,
and ensure that they are not accessible from the Internet.
- -Locate control system networks and remote devices behind firewalls, and
isolate them from the business network.
- -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. Also recognize that
VPN is only as secure as the connected devices.
ICS-CERT reminds organizations to perform proper impact analysis and risk
assessment prior to deploying defensive measures.
ICS-CERT also provides a section for control systems security recommended
practices on the ICS-CERT web page. Several recommended practices are
available for reading and download, including Improving Industrial Control
Systems Cybersecurity with Defense-in-Depth Strategies.
