Also recognize VPN is only as secure as the connected devices.</p> <p>CISA reminds organizations to perform proper impact analysis and risk assessment prior to deploying defensive measures.</p> <p>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.</p> <p>CISA encourages organizations to implement recommended cybersecurity strategies for proactive defense of ICS assets.</p> <p>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.</p> <p>Organizations observing suspected malicious activity should follow established internal procedures and report findings to CISA for tracking and correlation against other incidents.</p> <p>CISA also recommends users take the following measures to protect themselves from social engineering attacks:</p> <p>Do not click web links or open attachments in unsolicited email messages.</p> <p>Refer to Recognizing and Avoiding Email Scams for more information on avoiding email scams.</p> <p>Refer to Avoiding Social Engineering and Phishing Attacks for more information on social engineering attacks.</p> <p>No known public exploitation specifically targeting these vulnerabilities has been reported to CISA at this time.
