%0 Journal Article %T Title: Security in Requirement Engineering for Qualitative Products %A Isma Hameed %J International Journal of Engineering and Technology %@ 1793-8236 %D 2012 %R 10.7763/IJET.2012.V4.476 %X Abstract¡ªThe objective of defining security requirements for a system is to map the practical security requirements statements with the results of risk and threat analysis. Under investigation the securities risks of the system can manage (cancel, mitigate or maintain). Like system engineering security engineers must develop appropriate threat models. Security engineers must select those security measures which are most needed for market success. To improve the quality of the artifacts such as requirements documents the software engineers must use models early in the life cycle. In our research we have proposed a model ¡°integration of security with functional requirements model¡±. By using this model the security issues defined at the requirement engineering phase and it has followed in the next stages of the SDLC, We had proved our results by checking the efficiency of the architecture after applying the proposed model on a payment system. %U http://www.ijetch.org/show-46-362-1.html
