cannot immediately update the product, Mitsubishi Electric recommends taking
the following mitigation measures to minimize risk:
o Install the fixed version GX Works2, GX Works3, or MELSOFT Navigator on the
PC on which the product is installed. This is because these three products
provide comprehensive countermeasures that give the same countermeasure
effect to other products installed in the same folder (e.g. C:Program
filesMELSOFT).
o Operate the products under an account that does not have administrator's
privileges.
o Install an antivirus software in computers using the products.
o Restrict network exposure for all control system devices or systems to the
minimum necessary and ensure they are not accessible from untrusted
networks and hosts.
o Locate control system networks and remote devices behind firewalls and
isolate them from the network.
o Use virtual private network (VPN) when remote access is required.
Additional information about the vulnerability or the Mitsubishi Electric
compensating control is available by contacting a Mitsubishi Electric
representative .
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 us-cert.gov . Several recommended 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
