	abstract = {The development and evolution of secure open architecture systems has received insufficient consideration. Such systems are composed of both open source and closed software software components subject to different security requirements in an architecture in which evolution can occur by evolving existing components, replacing them, or refactoring their interfaces, interconnections and configuration. But this may result in possible security requirements conflicts and organizational liability for failure to fulfill security obligations. We are developing 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 (IP) licenses to now address software security licenses that can be associated with secure OA systems.},

	title = {Investigating the Acquisition of Software Systems that Rely on Open Architecture and Open Source Software},
	year = {2010},
	abstract = {In 2007-08, we began an investigation of problems, issues, and opportunities that arise during the acquisition of software systems that rely on open architectures and open source software. The current effort funded for 2009 seeks to continue and build on the results in this area, while refining its focus to center on the essential constraints and tradeoffs we have identified for software-intensive systems with open architecture (OA) and continuously evolving open source software (OSS) elements. The U.S. Air Force, Army, and Navy have all committed to an open technology development strategy that encourages the acquisition of software systems whose requirements include the development or composition of an OA for such systems, and the use of OSS systems, components, or development processes when appropriate. Our goal is to further develop and document foundations for emerging policy and guidance for acquiring software systems that require OA and that incorporate OSS elements. This report documents and describes the findings and results that we have produced as a result of our research into the area of the acquisition of software systems that rely on OA and OSS. In particular, it includes four research papers that have been refereed, reviewed, presented, and published in national and international research conferences, symposia, and workshops.},
