Recommended Practices

CISA recommends users take defensive measures to minimize the risk of exploitation of this vulnerability, such as:

Recommended Practices

When remote access is required, use more secure methods, such as Virtual Private Networks (VPNs), recognizing VPNs may have vulnerabilities and should be updated to the most current version available. Also recognize VPN is 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/ics. 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/ics 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.
