Extending XP Practices to Support Security Requirements Engineering
This paper proposes a way of extending eXtreme Programming (XP) practices, in particular the original planning game and the coding guidelines, to aid the developers and the customer to engineer...

While cryptography, access control, accountability, and other security technologies have received a great deal of attention, to our knowledge this is the first attempt to address systematically the...
View ArticleThe Secondary and Approximate Authorization Model and its Application to...
We introduce the concept, model, and policy-specific algorithms for inferring new access control decisions from previous ones. Our secondary and approximate authorization model (SAAM) defines the...

Request response access control systems that use Policy Decision Points have their reliability and latency bounded by network communication. We propose the use of a secondary decision point that...

As distributed enterprise systems scale up and become increasingly complex their authorization infrastructures are facing new challenges. Conventional request-response authorization architectures...
View ArticleMultiple-Channel Security Architecture and Its Implementation over SSL
This paper presents multiple-channel SSL (MC-SSL), an architecture and protocol for protecting client-server communications. In contrast to SSL, which provides a single end-to-end secure channel,...
