Advisory2019-01_CDS-64543.pdf
As part of a security strategy, 3S-Smart Software Solutions GmbH recommends the
following general defense measures to reduce the risk of exploits:
o Use controllers and devices only in a protected environment to minimize
network exposure and ensure that they are not accessible from outside.
o Use firewalls to protect and separate the control system network from other
networks.
o Use VPN (virtual private networks) tunnels if remote access is required.
o Activate and apply user management and password features.
o Limit the access to both development and control system by physical means,
operating system features, etc.
o Protect both development and control system by using up-to-date virus
detecting solutions. For more information and general recommendations for
protecting machines and plants, see also the CODESYS security whitepaper at
https://customers.codesys.com/fileadmin/data/customers/security/
CODESYS-Security-Whitepaper.pdf
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
on the ICS webpage on us-cert.gov in the Technical Information Paper,
ICS-TIP-12-146-01B--Targeted Cyber Intrusion Detection and Mitigation
Strategies .
Organizations observing any suspected malicious activity should follow their
established internal procedures and report their findings to CISA for tracking
and correlation against other incidents.
