3.4 RESEARCHER

Jon Hurtado of Sandia National Laboratory reported these vulnerabilities to CISA.

4. MITIGATIONS

The Mojave Inverter was a product of Enersys. When Outback Power was split off from Enersys recently, Mojave Inverter was moved to Outback Power, but without the resources to maintain the product. Outback Power may discontinue this product and has not yet addressed these vulnerabilities. CISA recommends disabling the networking features of this product until a replacement product can be acquired.

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

  • Disable un-used functions.
  • 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.

CISA also recommends users take the following measures to protect themselves from social engineering attacks:

No known public exploitation specifically targeting these vulnerabilities has been reported to CISA at this time.
