Sunway products are deployed across a wide variety of industries including petroleum, petrochemical, defense, railways, coal, energy, pharmaceutical, telecommunications, water, and manufacturing.

Mitigation

ICS-CERT recommends that users take defensive measures to minimize the risk of exploitation of these vulnerabilities. Specifically, users should:

• Minimize network exposure for all control system devices. Control system devices should not directly face the Internet.a
• Locate control system networks and devices behind firewalls, and isolate them from the business network.
• If remote access is required, employ secure methods such as Virtual Private Networks (VPNs), recognizing that VPN is only as secure as the connected devices.

ICS-CERT reminds organizations to perform proper impact analysis and risk assessment prior to taking defensive measures.
