4. MITIGATIONS

Planet Technology recommends users upgrade to version 1.305b241111 or later.

CISA recommends users take defensive measures to minimize the risk of exploitation of these vulnerabilities, such as:

  • 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.

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/ics. 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/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 CISA for tracking and correlation against other incidents.

5. UPDATE HISTORY

  • December 05, 2024: Initial Publication

ASD’s ACSC, CISA, and US and International Partners Release Guidance on Choosing Secure and Verifiable Technologies

Today, CISA—in partnership with the Australian Signals Directorate Australian Cyber Security Centre (ASD ACSC), and other international partners—released updates to a Secure by Design Alert, Choosing Secure and Verifiable Technologies. Partners that provided recommendations in this alert include:

  • The Canadian Centre for Cyber Security (CCCS).
  • United Kingdom’s National Cyber Security Centre (NCSC-UK).
  • New Zealand’s National Cyber Security Centre (NCSC-NZ).
  • Republic of Korea’s National Intelligence Service (NIS) and NIS’ National Cyber Security Centre (NCSC).

Cyber threats to user privacy and data are growing, requiring customers to evaluate their processes for acquiring products and services from technology manufacturers. Proactive integration of security mitigations into the procurement process can assist in managing risks present within the technology supply chain and reduce costs for organizations. This guidance aids procuring organizations and manufacturers of digital products and services in choosing and developing technology that is secure by design. This is an update to previously released guidance (Secure by Design Choosing Secure and Verifiable Technologies).

CISA and partners encourage all organizations to read the guidance to assist with making secure and informed choices when procuring digital products and services. Software manufacturers are also encouraged to incorporate the secure by design principles and practices found in the guidance. To learn more about secure by design principles and practices, visit CISA’s Secure by Design webpage.

CISA Releases New Public Version of CDM Data Model Document

Today, the Cybersecurity and Infrastructure Security Agency (CISA) released an updated public version of the Continuous Diagnostics and Mitigation (CDM) Data Model Document. Version 5.0.1 aligns with fiscal year 2023 Federal Information Security Modernization Act (FISMA) metrics.

The CDM Data Model Document provides a comprehensive description of a common data schema to ensure that prescribed diagnostic activities within CDM solutions are consistent across all participating federal agencies. Agencies leverage the common data schema to accomplish these critical objectives: 

  • Reduce agency threat surface.
  • Increase visibility into the federal cybersecurity posture.
  • Improve federal cybersecurity response capabilities.
  • Streamline FISMA reporting.

Vendors also can benefit from the CDM Data Model Document.
