MitigationLocate control and safety system networks and remote devices behind firewalls and isolate them from the business network. MitigationInstall physical controls so no unauthorized personnel can access your industrial control and safety systems, components, peripheral equipment, and networks. MitigationPlace all controllers in locked cabinets and never leave them in the "Program" mode. MitigationNever connect programming software to any network other than the network intended for that device.
MitigationScan all methods of mobile data exchange with the isolated network such as CDs, USB drives, etc. before use in the terminals or any node connected to these networks. MitigationNever allow mobile devices that have connected to any other network besides the intended network to connect to the safety or control networks without proper sanitation. MitigationMinimize network exposure for all control system devices and systems and ensure that they are not accessible from the Internet. MitigationWhen remote access is required, use secure methods, such as virtual private networks (VPNs).
Recognize that VPNs may have vulnerabilities and should be updated to the most current version available. Also, understand that VPNs are only as secure as the connected devices. 1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H CVE-2025-46817 The affected product uses Redis, an open-source, in-memory database. com/support/ MitigationAfter installing ProLeiT-2025-001, disable the eval commands in Redis on the application server, VisuHub, engineering workstations, and workstations with emergency mode functionality MitigationForce usage of secure Redis configuration templates in system settings as documented in the patch manual MitigationRestart all patched servers and workstations MitigationSchneider Electric strongly recommends the following industry cybersecurity best practices.

Recommended Practices CISA recommends users take defensive measures to minimize the risk of exploitation of these vulnerabilities. Minimize network exposure for all control system devices and/or systems, ensuring they are not accessible from the Internet. Locate control system networks and remote devices behind firewalls and isolating them from business networks.
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. CISA reminds organizations to perform proper impact analysis and risk assessment prior to deploying defensive measures. 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.
CISA encourages organizations to implement recommended cybersecurity strategies for proactive defense of ICS assets. gov/ics in the technical information paper, ICS-TIP-12-146-01B--Targeted Cyber Intrusion Detection and Mitigation Strategies. Organizations observing suspected malicious activity should follow established internal procedures and report findings to CISA for tracking and correlation against other incidents. CISA also recommends users take the following measures to protect themselves from social engineering attacks: Do not click web links or open attachments in unsolicited email messages.
