Recommended Practices
NCCIC recommends users take defensive measures to minimize the risk of exploitation of this vulnerability. Specifically, users should: Restrict access to Port 2455; 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.
Recommended Practices
NCCIC reminds organizations to perform proper impact analysis and risk assessment prior to deploying defensive measures.
Recommended Practices
NCCIC 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.
Recommended Practices
Additional mitigation guidance and recommended practices are publicly available in the NCCIC Technical Information Paper, ICS-TIP-12-146-01B--Targeted Cyber Intrusion Detection and Mitigation Strategies, that is available for download from the ICS-CERT website.
Recommended Practices
Organizations observing any suspected malicious activity should follow their established internal procedures and report their findings to NCCIC for tracking and correlation against other incidents.
