Towards Fit for Purpose Security in Military Systems
ABSTRACT
In security critical communities such as the military, system design is underpinned by the separation and sharing of resources based upon protective markings, user clearance and a ‘need to know’ policy. However, this approach can impede the ability to respond to changing resource and information sharing requirements. To address the problem, this paper proposes ‘fit for purpose’ security which seeks to balance flexibility against high assurance through the Non-Persistent Capability Concept (NPC2). The NPC2 is applied in the design, development and implementation of adaptable security. This paper focuses on the NPC2 architecture and presents some preliminary findings from a small-scale prototype based on the proposed framework. The work has application in markets other than the military and should be of interest to system and security architects and decision makers alike.
