Several recommended practices are available for reading and download, including Improving Industrial Control Systems Cybersecurity with Defense-in-Depth Strategies.Īdditional mitigation guidance and recommended practices are publicly available on the ICS-CERT website in the Technical Information Paper, ICS-TIP-12-146-01B-Targeted Cyber Intrusion Detection and Mitigation Strategies. NCCIC also provides a section for control systems security recommended practices on the ICS-CERT web page.

NCCIC reminds organizations to perform proper impact analysis and risk assessment prior to deploying defensive measures. Also recognize that VPN is only as secure as the connected devices. 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.NCCIC also recommends users take defensive measures to minimize the risk of exploitation of this vulnerability.
