Software assurance towards better IT service

Much active research has been done on service science in order to improve productivity, efficiency and customer satisfaction of IT service. If any software application or module in IT service behaves incorrectly, service quality and customer satisfaction will decrease significantly. In order to solve such problems, research on software assurance has been drawn much attention recently. Most widely recognized research has been carried out by various government agencies and research institutes such as DHS, DoD, NIST, NASA, SAFECode, CWE™, and SANS. This paper investigates various research on software assurance and discusses the unconsidered matters that have not been studied or solved yet. Finally, a system for the improved software assurance is proposed.
