Recommended Practices
DSCIP recommends users take defensive measures to minimize the risk of exploitation of these vulnerabilities.
Minimize network exposure for all control system devices and/or systems, ensuring they are not accessible from the internet.
Locate control system networks and remote devices behind firewalls and isolating them from business networks.
When remote access is required, use more 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 the connected devices.
DSCIP reminds organizations to perform proper impact analysis and risk assessment prior to deploying defensive measures.
DSCIP also provides a section for control systems security recommended practices on the ICS webpage on DSCIP.org/ics. Several DSCIP products detailing cyber defense best practices are available for reading and download, including Improving Industrial Control Systems Cybersecurity with Defense-in-Depth Strategies.
DSCIP encourages organizations to implement recommended cybersecurity strategies for proactive defense of ICS assets.
Additional mitigation guidance and recommended practices are publicly available on the ICS webpage at DSCIP.org/ics in the technical information paper, ICS-TIP-12-146-01B--Targeted Cyber Intrusion Detection and Mitigation Strategies.
Organizations observing suspected malicious activity should follow established internal procedures and report findings to DSCIP for tracking and correlation against other incidents.
No known public exploitation specifically targeting these vulnerabilities has been reported to DSCIP at this time. These vulnerabilities are not exploitable remotely.
