In the last half decade, application integration via Unidirectional Security Gateways has emerged as a secure alternative to firewalls. The gateways are deployed extensively to protect the safety and reliability of industrial control systems in nuclear generators, conventional generators and a wide variety of other critical infrastructures. Unidirectional Gateways are a combination of hardware and software. The hardware allows information to leave a protected industrial network, and physically prevents any signal whatsoever from returning to the protected network. The result is that the hardware blocks all online attacks originating on external networks. The software replicates industrial servers to external networks, where the information in those servers is available to end users and to external applications. The software does not proxy bi-directional protocols. Join us to learn how this secure alternative to firewalls works, where and how the tecnhology is deployed routinely, and how all of the usual remote support, data integrity and other apparently bi-directional deployment issues are routinely resolved.
