Multi-level security

R&S®NAVICS MLS goes beyond the solutions known from R&S®NAVICS IP and provides certified components that ensure secure handling of sensitive information by physically separating “classified networks”. Highly secure crypto modules in the voice terminals assign a tamper-proof signature to all voice packets that will be sent to networks with lower security levels. In addition to the traffic control provided by Ethernet switches, the Rohde & Schwarz certified gateway filters allow only voice packets with a matching signature to pass. A separate filter model for management traffic enables secure management of the overall system from a central communications control instance.
