CISA recommends users take defensive measures to minimize the risk of exploitation of these vulnerabilities. Specifically, users should:

• Ensure the least-privilege user principle is followed.
• Set unique and secure passwords for all products requiring authentication.
• Minimize network exposure for all control system devices and/or systems, and ensure they are not accessible from the Internet https://www.cisa.gov/uscert/ics/alerts/ICS-ALERT-10-301-01 .
• Locate control system networks and remote devices behind firewalls and isolate them from business networks.
