The Navy and the Department of Defense (DoD) are increasingly dependent on networks and associated net-centric operations to conduct military missions. As a result, a vital goal is to establish and maintain dependable networks for ship and multiship (e.g., strike group) networks. An essential step in maintaining the dependability of any networked system is the ability to understand and measure the network's dependability. The term network dependability is broad. It is determined, in part, by the availability and reliability of information technology (IT) systems and the functions these systems provide to the user. For the Navy, qualitative standards for network dependability include (1) the ability of the Navy's IT systems to experience failures or systematic attacks without impacting users and operations, and (2) achievement of consistent behavior and predictable performance from any access point. The RAND National Defense Research Institute (NDRI) was asked to develop an analytical framework to evaluate C4I (command, control, communications, computers, and intelligence) network dependability. This requires an understanding of the availability and reliability of the network and its supporting systems, subsystems, components, and subcomponents. In addition, RAND was asked to improve upon an existing tool, initially developed by the Space and Naval Warfare Systems Command (SPAWAR), to help better evaluate network dependability.
