Cross-domain use case: Connected military simulations
Strategic military information in a network should not fall into the wrong hands. This is why securing connections with other networks is crucial, even if those connections are with friendly nations. A Cross-domain interface can prevent strategic data from ending up in the wrong place.
The use case described below shows how a connected military simulation can be secured using a Cross-domain interface. More Cross-domain use cases.
The situation: Connected Dutch and German military simulations
The Netherlands and Germany are carrying out joint simulated military exercises. In the course of the exercise, a Dutch fighter jet simulation is connected to a German tank simulation through the DIS protocol (Distributed Interactive Simulation). Simulation systems use this protocol to exchange data to create a joint training environment. This allows Dutch and German military to train together in one single simulation environment.
The risk: Secret information in the simulation environment
Military simulations often use real-world information, for example information concerning certain capacities, such as the maximum speed of a rocket. Much of this information is secret and may not be shared even with a friendly power. Because simulation information is exchanged in both directions, there is a risk that secret Dutch information will end up in the German simulation.
The solution: Cross-domain interface with data filter
A bi-directional PrimeCross data filter is placed between the simulations. Data from the German simulation is received unimpeded in the Dutch domain. Data from the Dutch domain is filtered using customized filter policies. Only data that meets the conditions specified in the policy is shared with the German domain.
PrimeProxy servers equipped with PrimeDocks software are installed either side of the PrimeCross. This software supports the DIS protocol and prepares the data for filtering. All devices (3U rack space) are installed in the environment of the Dutch fighter jet simulation.
