Architecture Provides Complete Red/Black Separation

A Rohde & Schwarz voice communications system recently passed a rigorous site acceptance test after several weeks’ intensive testing with the Belgian Air Component, the company announced on 3 December.

Featuring a single human-machine interface and redundant secure and trusted configurations for both classified and unclassified domains, the system is used in a Belgian air surveillance and defence command centre.

The scope of delivery includes one fully redundant system with over 43 controller working positions. The redundant configuration architecture provides for each domain to be equipped with the necessary number of radios and telephone interfaces. The two domains are strictly separated and connected to each controller working position with a trusted audio switch, ensuring the security level for each domain all the way to the controller headset.

“Rohde & Schwarz provides the most innovative technology on the market and has an established track record,” commented Yves Colot, representative of the Belgian MoD. “We rely on the state-of-the-art Rohde & Schwarz solution to provide safety, security and efficiency in all mission-critical domains.”

“Customer feedback was very positive and they were extremely satisfied with [the] speed at which issues were covered and new requests were implemented,” observed Constantin von Reden, VP Market Segment ATC at Rohde & Schwarz.

Prior to the installation and acceptance of the Belgian Air Component’s system, the trusted audio switch was thoroughly tested by the German Federal Office for Information Security and passed a common criteria evaluation with an EAL 4 assurance level.
