Abstract

There is growing awareness of the need to protect digital resources and services in both corporate and home ICT scenarios. Meanwhile, communication tools tailored for corporations are blurring the line between communication mechanisms and (near) real-time resource sharing. The resulting requirement for near real-time policy-based access control is technically challenging. In a corporate domain, such access control mechanisms must be unobtrusive and comply with strict security objectives. Thus policy evaluation performance needs to be considered while addressing traditional security concerns. This paper discusses policy system design principles that motivate a novel Policy Decision Point (PDP) implementation and associated policy language. These principles are consistent with recent web development techniques designed to improve performance and scalability. Given a modern web development stack comprising a language (Javascript), a framework (Node.js) and a database management system (Redis), the proposition is that significant performance gains can be made. Our performance experiments suggest this is the case when, through various design iterations, our prototype PDP implementation is compared with an established, Java/XACML-based access control PDP implementation. The experiments presented in this paper suggest that newer technologies offer better performance. The analysis suggests that this is because they offer a more efficient data representation and make better use of computing resources.
