the most recent Secure Deployment Guide (SDG) instructions(link is external).

Please refer to GE Digital’s security bulletin(link is external) for more
information.

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

defense best practices are available for reading and download, including
Improving Industrial Control Systems Cybersecurity with Defense-in-Depth
Strategies.

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.

No known public exploits specifically target this vulnerability. This
vulnerability is not exploitable remotely.
