the patch, which is available on the Honeywell Mywebtech portal .
o As a best practice, Honeywell recommends users isolate systems from the
Internet or create additional layers of defense to their system from the
Internet by placing the affected hardware behind a firewall or into a DMZ.
o If remote connections to the network are required, consider using a VPN or
other means to ensure secure remote connections into the network where the
device is located.
CISA recommends users take the followingdefensive measures to minimize the risk
of exploitation from social engineering attacks:
o Do not click web links or open unsolicited attachments in email messages.
o Refer to Recognizing and Avoiding Email Scams for more information on
avoiding email scams.
o Refer to Avoiding Social Engineering and Phishing Attacks for more
information on social engineering attacks.
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
