SSUS (Secure Software Update Solution) by Owl Cyber Defense is designed to securely transfer software updates and other files into control networks. SSUS provides a mechanism that takes previously vetted files and subjects them to a comprehensive set of security scans. Once approved, SSUS uses Owl's data diode technology to transfer files across the security boundary of the OT network into the plant. SSUS eliminates the security risk from using portable media devices like flash drives.
