evaluating the impact of these patches in a "testing and development
environment" or on an offline infrastructure.
o Users should contact Schneider Electric for assistance in removing a patch.
o Schneider Electric recommends that users ensure devices supporting ION
protocol are not exposed to the internet or other untrusted networks. Users
should apply the best practices for network hardening as documented in the
product user guide and the Schneider Electric Recommended Cybersecurity
Best Practices .
o Additional configuration steps and supporting software are required to
utilize the secure ION feature. Please refer to the relevant product
documentation or contact customer care for additional details and support.
For more information, see Schneider Electric's security advisory
SEVD-2023-129-03 .
Schneider Electric strongly recommends the following industry cybersecurity
best practices:
o Locate control and safety system networks and remote devices behind
firewalls and isolate them from the business network.
o Install physical controls so no unauthorized personnel can access your
industrial control and safety systems, components, peripheral equipment,
and networks.
o Place all controllers in locked cabinets and never leave them in the
"Program" mode.
o Never connect programming software to any network other than the network
intended for that device.
o Scan all methods of mobile data exchange with the isolated network such as
CDs, USB drives, etc. before use in the terminals or any node connected to
these networks.
o Never allow mobile devices that have connected to any other network besides
the intended network to connect to the safety or control networks without
proper sanitation.
o Minimize network exposure for all control system devices and systems and
ensure that they are not accessible from the internet.
o When remote access is required, use secure methods, such as virtual private
networks (VPNs). Recognize that VPNs may have vulnerabilities and should be
updated to the most current version available. Also, understand that VPNs
are only as secure as the connected devices.
CISA recommends users take defensive measures to minimize the risk of
exploitation of this vulnerability. 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 at 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 .
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 targeting these vulnerabilities have been
reported to CISA at this time.
