In the blooming era of the Internet of Things (IoT), trust has been accepted as a vital factor for provisioning secure, reliable, seamless communications and services. However, a large number of challenges still remain unsolved due to the ambiguity of the concept of trust as well as the variety of divergent trust models in different contexts. In this research, we augment the trust concept, the trust definition and provide a general conceptual model in the context of the Social IoT (SIoT) environment by breaking down all attributes influencing trust. Then, we propose a trust evaluation model called REK, comprised of the triad of trust indicators (TIs) Reputation, Experience and Knowledge. The REK model covers multi-dimensional aspects of trust by incorporating heterogeneous information from direct observation (as Knowledge TI), personal experiences (as Experience TI) to global opinions (as Reputation TI). The associated evaluation models for the three TIs are also proposed and provisioned. We then come up with an aggregation mechanism for deriving trust values as the final outcome of the REK evaluation model. We believe this article offers better understandings on trust as well as provides several prospective approaches for the trust evaluation in the SIoT environment.

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.

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

There has been a phenomenal increase in the use of web applications in every facet of human endeavor. From education, healthcare, banking, business to governance and so much more now depends on secure web applications. This accelerated growth in the use of web applications has led to increase in the complexity of security and hence the present day developers have to contribute more significantly towards meeting the users’ requirements. However, the high security of web application is not yet efficacious enough because the durability of web application is not as much as it should be. In this context, it is important to consider that ensuring sustainability of security at the early stage of web application development process may reduce costs and rework entailed during the development of secure and durable web applications. Hence, there is a need to focus on increasing the life-span of a secure web application. Quantitative estimation of security-durability plays a significant role for improving the life-span of a secure web application. Thus, to optimize the security assurance effort for a specific life-span, this paper is aimed at estimating the security-durability of web application. For estimating security-durability, this paper uses a hybrid approach of Hesitant Fuzzy (HF) sets, Analytic Hierarchy Process (AHP) and Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) techniques. The effectiveness of the combined approach of HF-AHP-TOPSIS is tested for its accuracy in a web application for an academic institution, Babasaheb Bhimrao Ambedkar University in India. To check the sensitivity of outcomes, authors of the paper have taken altered forms of the University’s web application. The result established contains the security-durability assessment. This work seeks to be an important contribution in enhancing the security-durability and would be beneficial for experts who are working in this domain.

A Knowledge-Based Integrated System of Hesitant Fuzzy Set, AHP and TOPSIS for Evaluating Security-Durability of Web Applications

Acceptance of any new approach by the organizations depends upon the users’ needs. Currently, reducing the cost and time invested in maintenance is a major challenge for the practitioners. Moreover, symmetrical and optimal maintenance is the need of the hour and it can be achieved by increasing the durability of software. Many attributes of the quality may affect the durability of the software and identification of durability attributes is a crucial task at the early stage of software development. Thus, it is a problem that contains multi-criteria within it. With the help of quantitative estimation, software durability may be assessed symmetrically and increased. In this row, the authors of this article have attempted to posit an effective technique to assess the durability of software. Based on empirical data through research, the presenters of this article suggest that fuzzy-based symmetrical method of Analytic Network Process (ANP) and Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) would be an accurate methodology for assessing the durability of software. For determining the efficacy of this assessment, the researchers took six alternative software of a University. The results, as presented in this paper, would serve as guidelines for the practitioners who aim at achieving the preferred software durability.

Evaluating Performance of Software Durability through an Integrated Fuzzy-Based Symmetrical Method of ANP and TOPSIS

Background Security is an integral aspect of the development of quality software. Furthermore, security durability is even more imperative and in persistent demand due to high investment in recent years. To achieve the desired target of efficacious and viable durability of security services, there needs to be nodal focus on durability along with security. Unfortunately, the highly secure design of software becomes worthless because the durability of security services is not as it should be. Methods Security durability attributes have their own impact while integrating security with durability and assessment of security durability plays a crucial role during software development. Within this context, this paper estimates the security durability of the two alternatives versions of a locally developed software called version 1 and version 2. To assess the security durability, authors are using the hybrid fuzzy analytic hierarchy process decision analysis approach. Results The impact of the security durability on other attributes has been evaluated quantitatively. The result obtained contains the assessment of security durability. The study posits conclusions which are based on this result and are useful for practitioners to assess and improve the security life span of software services.

Security is a peak significant quality element in the pitch of software engineering. Software security improvement is easily done with the support of factors, models and metrics of security. Software security should be analyzed with the help of its security factors. Security dimension is the main attribute in evaluation, executing, and calculating security in the way to organize and develop quality of software. It is to be identified that qualifications of security factors increased through inspecting damages, discriminating susceptibility and attacks in design development process. This review is discussing the description and categorization of accessible security properties. Durability is an attribute of security that refers to the capability of software to conclude of a creation on time. Software security is affected with security attributes as well as durability. A stable state of the secure software enhances additional security.

Revisiting Software Security: Durability Perspective

Testability has always been an elusive concept. Its correct measurement or evaluation is a difficult exercise because of the potential factors affecting testability. It has been revealed from literature survey that researchers and practitioners had made some efforts to measure testability at source code level. Measuring testability at code level leads to late arrival of design flaws. Changes in design at a later stage costs more than the changes made at there itself. It is an inevitable fact that by estimating testability, a decision on such a change may be incorporated at design phase. Considerable efforts have been made to list out testability factors in order to find out measurable characteristics of software testability. It has been inferred from the literature on testability factors that there is a heavy need of proposing a commonly accepted set of the factors affecting software testability. This paper puts forth an effort in producing a set of testability factors in terms of direct measurable. Using the identified set of factors, software characteristics and metrics, testability may be quantified early in design phase.

The production of traditional, complementary and alternative medicines, in particular those based on plant materials, is a global business. A recommended human diet contains significant quantities of polyphenolics, as they have long been assumed to be anti-oxidants that scavenge excessive, damaging, free radicals arising from normal metabolic processes. Flavonoids and other phenolic compounds are widely distributed in foods and are important constituents of the human diet. The phenolic compounds may be protective against cardiovascular disease and have certain potential anticarcinogenic properties due to their anti-oxidant activity or other properties. The content of the anti-oxidants, phenols and flavonoids in foods has been evaluated by different methods. With the advent of the nutraceutical industry, Mulberry has become one of the most popular herbal medicines of recent years, although its use dates back many hundreds of years to ancient Chinese medicine. Polyphenols such as scopoletin, querectin, morin, hydroxycoumarin, rutin, isoquercetin, querectin 3-malynoglucoside (Q3MG) had been identified as natural antioxidants in mulberry leaves. Scopoletin may play an important role in regulating free radical generation via metabolic pathways such as mitochondrial transport of long chain free fatty acids and cytochrome-p450 transport chain.

Delivery of reliable software has become a primary concern for the successful software development organizations. Successful and reliable software can be delivering only when the requirement documentation is reliable. There is various threats point in the requirement phase that causes for requirement defects and so defect occurring in the further phases of Software Development process. A key aspect of delivering and improving the software reliability it is necessary to be confident that the requirement delivered to the further phases must be reliable. Reliability measurement is the best characteristic of assessing gathered requirement statistics and their respective compiled documentation. A reliable requir ement can be produce only after removing or resolving all types of requirement defects. Here we describe an automated requirement defect identification approach through introducing Defect Data Dictionary which is directly accessible by Requirement Inspection Participant (RIP) and Requirement Inspection Method (RIM) for comparative requirement inspection. This paper provides an overview of the automated approach of how the requirement defect are being detected and resolved to achieve Reliable Requirement Specification (RRS) [8]. Here, the assessment of reliability with respect to requirement defect before and after mitigation through Requirement Defect Detection Framework is given. This may help out requirement analyst for producing the Reliable Requirement Specification.
