Supporting Consistency during the Development and Evolution of Quality Unified Use-Misuse Case Models

Abstract

In the domain of scenario-based modeling, use case modeling has been extended several times to introduce security related concepts such as misuse, abuse, vulnerability and safeguarding. The most advanced model is the Unified Use-Misuse Case Model (UUMCM) (Arogundade et. al., 2011). A low quality UUMCM will not only cause the development of a system that does not meet its business requirements, but also a system that is insecure. This paper proposes an authoring structure that specifically designed to improve one particular quality attribute; structural consistency. Automation support has been developed for this structure. Two different approaches have been used to demonstrate the feasibility and application of the proposed structure. In both validation approaches, the results show that the structure can be used to ensure structural consistency in UUMCMs throughout their development and evolution.
