An Integrated Approach of Fuzzy Logic, AHP and TOPSIS for Estimating Usable-Security of Web Applications

Abstract

Security and usability are often thought of as being contradictive in nature. One affects the other negatively. The relation and trade-offs between usability and security must be detected during developing web application to satisfy the user's requirements with security perspective. Current approaches of usable-security emphasizes on building systems that are easy to use and secure as well. Hence, this paper is recognizing usability-security as a problem with different attributes contributing towards it. Further, there is a need to assess this problem for the satisfaction of the end user. In this context, this study proposes the track of Fuzzy AHP-TOPSIS (Analytic Hierarchy Process-Technique for Order of Preference by Similarity to Ideal Solution) technique to assess the usable-security of web application and also identifies the most prioritized attribute contributing towards building usable-security of web application. Moreover, to corroborate the efficacy of the proposed technique, the authors have tested the results on the institutional web applications. The results of the assessment undertaken in this study and the findings tabulated thereafter will be a helpful reckoner for the developers while designing web applications that afford optimum usable-security.

Evaluating the Impact of Malware Analysis Techniques for Securing Web Applications through a Decision-Making Framework under Fuzzy Environment

“…Furthermore, various university software applications were also used to verify the findings. Kumar et al [36] identified usability-security as a challenge with numerous attributes referring to it. In addition, they investigated that the question needs to be evaluated for the convenience of the end consumer.…”

A Hybrid Fuzzy Rule-Based Multi-Criteria Framework for Security Assessment of Medical Device Software

“…Multiple approaches are available for solving the decision making problem. If multiple contentions occur at the time of calculation, then we can use MCDM approaches which support the experts' decision [18,19,20]. For medical device software security assessment, we have used the Fuzzy ANP-TOPSIS approach.…”

Fuzzy-Based Symmetrical Multi-Criteria Decision-Making Procedure for Evaluating the Impact of Harmful Factors of Healthcare Information Security

“…This paper covers the previous trends and attributes of malware attacks on the healthcare services and then tries to provide some significant factors with the help of experts' opinion that are affecting the healthcare organizations rapidly [16]. The article will also provide a scientific analysis of those factors through the hybrid approach of fuzzy AHP-TOPSIS methodology [17,18]. Fuzzy AHP-TOPSIS methodology is a pre-verified and old scientific multi criteria decision making technique that gives accurate as well as effective results in multi criteria decision situation [19][20][21].…”

“…In the first step of calculation, this paper used fuzzy AHP for evaluating the relevant weights through Equations (1)- (16). After that in next step, the experts prepared a comparison matrix and selected a variable with the help of Table 2 and Equation (18). In the following steps, the fuzzy matrix is normalized through Equation (19).…”
