Worldwide
Company headquarters location
Sweden
Recommended Practices
CISA recommends users take defensive measures to minimize the exploitation risk of these vulnerabilities, such as:
Recommended Practices
Ensure the least-privilege user principle is followed.
Recommended Practices
Set unique and secure passwords for all products requiring authentication.
Recommended Practices
Minimizing network exposure for all control system devices and/or systems, ensuring they are not accessible from the internet.
Recommended Practices
Locating control system networks and remote devices behind firewalls and isolating them from business networks.
Recommended Practices
When remote access is required, using 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. 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:
Recommended Practices
Do not click web links or open attachments in unsolicited email messages.
Recommended Practices
Refer to Recognizing and Avoiding Email Scams for more information on avoiding email scams.
Recommended Practices
Refer to Avoiding Social Engineering and Phishing Attacks for more information on social engineering attacks.
Recommended Practices
No known public exploits specifically target these vulnerabilities. These vulnerabilities are exploitable remotely. These vulnerabilities have low attack complexity.
