portal to bring together DoD software developers, users, <strong>and</strong> software engineering researchers virtually by enabling their<br />

collaboration on specifying <strong>and</strong> solving software producibility challenge problems. SPRUCE is based on the premise that well<br />

(CoI), dynamically evolving challenge problems with accompanying artifacts, <strong>and</strong> built-in experimentation facilities to<br />

reproduce the problems <strong>and</strong> evaluate solution benchmarks.<br />

<strong>The</strong> USA Air Force relies heavily on computer networks to transmit vast amounts of information throughout its<br />

organizations <strong>and</strong> with agencies throughout the Department of Defense. <strong>The</strong> data take many forms, utilize different protocols,<br />

<strong>and</strong> originate from various platforms <strong>and</strong> applications. It is not practical to apply security measures specific to individual<br />

applications, platforms, <strong>and</strong> protocols. Internet Protocol Security (IPsec) is a set of protocols designed to secure data traveling<br />

over IP networks, including the Internet. By applying security at the network layer of communications, data packets can be<br />

secured regardless of what application generated the data or which protocol is used to transport it. However, the complexity<br />

of managing IPsec on a production network, particularly using the basic comm<strong>and</strong>-line tools available today, is the limiting<br />

factor to widespread deployment. This thesis explores several visualizations of IPsec data, evaluates the viability of using<br />

visualization to represent <strong>and</strong> manage IPsec, <strong>and</strong> proposes an interface for a visual IPsec management application to simplify<br />

IPsec management <strong>and</strong> make this powerful security option more accessible to the information warfighter.<br />

Achieving Operability via the Mission System Paradigm<br />

In the past, flight <strong>and</strong> ground systems have been developed largely-independently, with the flight system taking the lead,<br />

<strong>and</strong> dominating the development process. Operability issues have been addressed poorly in planning, requirements, design,<br />

I&T, <strong>and</strong> system-contracting activities. In many cases, as documented in lessons-learned, this has resulted in significant<br />

avoidable increases in cost <strong>and</strong> risk. With complex missions <strong>and</strong> systems, operability is being recognized as an important<br />

end-to-end design issue. Never-the-less, lessons-learned <strong>and</strong> operability concepts remain, in many cases, poorly understood<br />

<strong>and</strong> sporadically applied. A key to effective application of operability concepts is adopting a ‘mission system’ paradigm. In<br />

this paradigm, flight <strong>and</strong> ground systems are treated, from an engineering <strong>and</strong> management perspective, as inter-related<br />

elements of a larger mission system. <strong>The</strong> mission system consists of flight hardware, flight software, telecom services, ground<br />

data system, testbeds, flight teams, science teams, flight operations processes, procedures, <strong>and</strong> facilities. <strong>The</strong> system is<br />

designed in functional layers, which span flight <strong>and</strong> ground. It is designed in response to project-level requirements, mission<br />

design <strong>and</strong> an operations concept, <strong>and</strong> is developed incrementally, with early <strong>and</strong> frequent integration of flight <strong>and</strong> ground<br />

components.<br />
