4. MITIGATIONS
Honeywell provided detailed information for mitigation on the insecure communication in Control Edge PLC\RTU. Please access the support document SN2020-04-17-01-ConotrolEdge-PLC-and- and-RTU-Secure-Communication (login required). Download this document and follow the step by step instructions. The user must be logged in to access the security notification.
Users who have difficulty accessing the document can contact Honeywell support.
CISA recommends users take defensive measures to minimize the risk of exploitation of this vulnerability. Specifically, users should:
Minimize network exposure for all control system devices and/or systems, and ensure that they are not accessible from the Internet.
Locate control system networks and remote devices behind firewalls, and isolate them from the business network.
When remote access is required, use secure methods, such as Virtual Private Networks (VPNs), recognizing that VPNs may have vulnerabilities and should be updated to the most current version available. Also recognize that VPN is only as secure as the connected devices.
CISA reminds organizations to perform proper impact analysis and risk assessment prior to deploying defensive measures.
Organizations observing any suspected malicious activity should follow their established internal procedures and report their findings to CISA for tracking and correlation against other incidents.
No known public exploits specifically target these vulnerabilities.
