“…Another approach for deciding on security requirements and design is proposed in [16], where probabilistic inference on security influence diagrams and Bayesian Networks are used to support trade-off analysis. In this work, authors discuss the criteria of the language for security requirements modeling and analyzing.…”

Abstract. In designing software systems, security is typically only one design objective among many. It may compete with other objectives such as functionality, usability, and performance. Too often, security mechanisms such as firewalls, access control, or encryption are adopted without explicit recognition of competing design objectives and their origins in stakeholders' interests. Recently, there is increasing acknowledgement that security is ultimately about trade-offs. One can only aim for "good enough" security, given the competing demands from many parties. This paper investigates the criteria for a conceptual modeling technique for making security trade-offs. We examine how conceptual modeling can provide explicit and systematic support for modeling and analyzing security trade-offs. We examine several existing approaches for dealing with trade-offs and security trade-offs in particular. From analyzing the limitations of existing methods, we propose an extension to the i* Framework for security trade-off analysis, taking advantage of its multiagent and goal orientation. The method was applied to several case studies used to exemplify existing approaches. The resulting models developed using different approaches are compared.

“…The analysis methods in the EA community including [2] [15], [16], [17], [18], [19], [20], [21], [22], [23], [24]. The main contributions of our approach which make it different from the approaches of group 2 are as below: a) In our approach, the criteria and sub-criteria of a quality attribute are given different weights according to the EA layers each of them belong to and also the importance of each EA layer in the enterprise.…”

An Approach towards Enterprise Architecture Analysis using AHP and Fuzzy AHP

Abstract-Enterprise Architecture (EA) as a discipline that manages large amount of models and information about different aspects of the enterprise can support decision making on enterprise-wide issues. In order to provide such support, EA information should be amenable to analysis of various utilities and quality attributes. In this regard, this paper provides an approach based on Fuzzy Analytical Hierarchy Process (AHP) towards EA analysis. It proposes an extended quantitative method of assessing quality attribute achievement of different scenarios using AHP and Fuzzy AHP based on the knowledge and experience of EA experts and domain experts. Due to the uncertainty in the judgments of participants, the crisp pair-wise comparison in the conventional AHP is insufficient and imprecise to capture the right judgments. Therefore, a fuzzy logic is introduced in the pair-wise comparison of AHP in one of steps of the method. The applicability of the proposed approach is demonstrated using a practical case study.Index Terms-Enterprise architecture analysis, quality attribute, analytical hierarchy process, fuzzy logic, fuzzy AHP.
