Recommended Practices
CISA recommends users take defensive measures to minimize the risk of exploitation.
Recommended Practices
Minimize network exposure for all control system devices and/or systems, ensuring they are not accessible from the internet.
Recommended Practices
Locate control system networks and remote devices behind firewalls and isolating them from business networks.
Recommended Practices
When remote access is required, use more secure methods, such as Virtual Private Networks (VPNs). Recognize VPNs may have vulnerabilities, should be updated to the most recent version available, and are only as secure as the connected devices.
Recommended Practices
CISA reminds organizations to perform proper impact analysis and risk assessment prior to deploying defensive measures.
Recommended Practices
CISA also provides a section for control systems security recommended practices on the ICS webpage on cisa.gov. 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.
Recommended Practices
CISA encourages organizations to implement recommended cybersecurity strategies for proactive defense of ICS assets.
Recommended Practices
Additional mitigation guidance and recommended practices are publicly available on the ICS webpage at cisa.gov in the technical information paper, ICS-TIP-12-146-01B--Targeted Cyber Intrusion Detection and Mitigation Strategies.
Recommended Practices
Organizations observing suspected malicious activity should follow established internal procedures and report findings to CISA for tracking and correlation against other incidents.
Recommended Practices
CISA also recommends users take the following measures to protect themselves from social engineering attacks: Do not click web links or open attachments in unsolicited email messages. Refer to Recognizing and Avoiding Email Scams for more information on avoiding email scams. Refer to Avoiding Social Engineering and Phishing Attacks for more information on social engineering attacks.

This can be done in the Tunnel/Mirror properties of Datahub. If Ports 4502\\TCP and 4503\\TCP are in use, configure authentication on all TCP connections. Instructions for doing this are below: Remove all permissions for the special user names \u201cTCP\u201d and \u201cMirror\u201d in the security properties of the DataHub. Create a group for users who are authorized, and allow \u201cBasicConnectivity\u201d for that group. The DataHub will then refuse all commands from unauthenticated TCP connections, and still allow authenticated users to connect. (http://www.cogentdatahub.com/Docs/cdh-dhsecurity.html)",
