    Student thesis: Master typesMaster in Computer science


    Argumentation is primarily a field of study and a philosophical discipline which has been widely taught for centuries. This discipline allows for the development and improvement of students’ critical thinking. It has also been studied in law schools as a part of training of future lawyers in defence of their client, especially in preparation and development of the most decisive arguments in favour of the latter. Many software packages have been developed to enable users to practice visual argumentation and to create his or her own argument maps.
    In this thesis, we have attempted to reconcile these software tools, designed to create visual arguments, with the field of computer security. This thesis explores the possibility of creating an argument map of security requirements using visualization argument software tools. More specifically, this thesis presents a comprehensive assessment of five different tools; Araucaria, ArguMed, Argumentative, Athena and Rationale, all designed to create visual argument maps. The presented assessment was based on a design of the "security requirement" argument and explores, for each tool, five different perspectives: the user interface, available features, the documentation and error handling, the notations used to represent the argument and the argumentation ontology underlying each tool. Finally, a discussion interprets the results and the relevance of these tools in the field of security requirements.
