    Recommended Practices
    CISA recommends users take defensive measures to minimize the risk of exploitation of this vulnerability.
    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). Recognize VPNs may have vulnerabilities, should be updated to the most recent version available, and are only as secure as the connected devices.
    CISA reminds organizations to perform proper impact analysis and risk assessment prior to deploying defensive measures.
    CISA also provides a section for control systems security recommended practices on the ICS webpage on cisa.gov. Several CISA products detailing cyber defense best practices are available for reading and download, including Improving Industrial Control Systems Cybersecurity with Defense-in-Depth Strategies.
    CISA 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 cisa.gov 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 CISA for tracking and correlation against other incidents.
    CISA also recommends users take the following measures to protect themselves from social engineering attacks:
    Do not click web links or open attachments in unsolicited email messages.
