Thomas Alspaugh is adjunct professor of Computer Science at Georgetown University, and visiting researcher at the Institute for Software Research at UC Irvine. His research interests are in software engineering and software requirements. Before completing his Ph.D., he worked as a software developer, team lead, and manager in industry, and as a computer scientist at the Naval Research Laboratory on the Software Cost Reduction project, also known as the A-7E project.
The role of software acquisition ecosystems in the development and evolution of secure open architecture systems has received insufficient consideration. Such systems are composed of software components subject to different security requirements in an architecture in which evolution can occur by evolving existing components or by replacing them. But this may result in possible security requirements conflicts and organizational liability for failure to fulfill security obligations. We have developed an approach for understanding and modeling software security requirements as “security licenses”, as well as for analyzing conflicts among groups of such licenses in realistic system contexts and for guiding the acquisition, integration, or development of systems with open source components in such an environment. Consequently, this paper reports on our efforts to extend our existing approach to specifying and analyzing software intellectual property licenses to now address software security licenses that can be associated with secure OA systems.
