Trustworthiness is an important emerging requirement for software systems deployed by the U. S. Air Force. Trustworthiness, briefly stated, is the ability of a software system to be safe, secure, and reliable under a normal operating environment. However, most software systems have not been developed with trustworthiness in mind. Therefore, how do we systematically identify deficit in trustworthiness in existing systems so that they may be re-engineered with trustworthiness as a priority The Non-Functional Requirements NFR Approach provides a framework for identifying gaps in trustworthiness in existing systems and recommending mechanisms to overcome this shortfall in re-engineered systems. In this project we applied the NFR Approach, as a case study to the middleware system called Phoenix used by the Air Force and determined an 89 shortfall in trustworthiness. The advantages of identifying this deficit include determination of trustworthiness in current systems, exploring environments in which current systems may be reused, and prioritizing trustworthiness requirements when these legacy systems are re-engineered.
