. To alleviate this, DARPA initiated the National Cyber Range (NCR) program to develop the architecture and software tools needed for a secure, self-contained cyber testing facility. Among NCR’s goals was the development of a range capable of rapid and automated reconfiguration of resources, broad scalability, and support for running simultaneous experiments at different security levels .
In this paper we present our architecture for the Range-level Command & Control System (RangeC2) developed as part of the Johns Hopkins University Applied Physics Laboratory’s implementation of the NCR . Our discussion includes the RangeC2’s functional and non-functional requirements, the rationale behind its partitioning into layered subsystems, an analysis of each subsystem’s fundamental mechanisms, and an in-depth look at their processing paradigms and data flows.
To meet the demands of this range, the RangeC2 was required to perform three primary jobs: 1) management of all range resources; 2) management of numerous concurrent experiments; and 3) enforcement of each experiment’s resource security and perimeter isolation. Our discussion of the architecture will show how these requirements were met while overcoming the RangeC2’s most critical challenges.
