4. MITIGATIONS
Packet Power recommends the following:
- Update the affected products to version 4.1.0 or later.
- Isolate devices whenever possible.
CISA recommends users take defensive measures to minimize the risk of exploitation of this vulnerability, such as:
- Minimizing network exposure for all control system devices and/or systems, ensuring they are not accessible from the internet.
- 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.
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.
