Security, privacy and trust oriented requirements modeling for examination system

The requirement engineering phase of Software Engineering (SE) deals with various activities starting from customer interaction to specifications of the requirements for the designing initiative. Now-a-days security, privacy and trustworthiness have become additional set of crucial requirements in view of the fact that software is vulnerable to various attacks. Many existing paradigms of SE deal with requirements, but less attention has been paid to address the issues of security, privacy and trust implementations. In practice, major attention is given to incorporate security aspects during coding and testing phases. Some paradigms address these issues, but they consider either security or privacy or trust requirements but not all of them together. We believe that security, privacy and trust requirements must be well collected, analyzed and specified through various stages of Requirement Engineering (RE) itself. This paper attempts to model RE activities incorporating security, privacy and trust requirements in effective way during all sub stages of RE phase. The activities of requirements modeling are well detailed and supported with case study of an online examination system of higher education (like University).
