A Unified Fuzzy-Based Symmetrical Multi-Criteria Decision-Making Method for Evaluating Sustainable-Security of Web Applications

Abstract

Although security is an integral aspect of any web application’s growth, sustainability is also a pivotal factor in maintaining the web application. It is clear that the software industry aims to develop different methods and initiatives for achieving high security while maintaining high sustainability. Unfortunately, web application protection is useless if the sustainability is low. Thus, the present day need calls for innovation in developing web applications that afford sustainable-security to the users. By improving sustainability along with web application protection, underlying security and sustainability attributes play a vital role in determining the symmetrical effect of the sustainability and security attribute to achieve the best outcome. Sustainability evaluation, therefore, uses security and sustainability qualities to achieve the desired sustainability security solutions. In this study, ten consecutive versions of two web applications were used to determine symmetrical sustainability. The authors used the Fuzzy Analytic Hierarchy Process (Fuzzy-AHP) mechanism to determine sustainability goals and long-term impact. Furthermore, the effect of security on sustainability is assessed, and vice versa. The findings in the paper will prove to be valuable for improving sustainability of the web application.
