| dc.description.abstract | Safety and security, and unifying these two aspects are important when eliciting requirements form both new and existing computer systems. As a mens to support this, the CHASSIS method was developed. With this a new issure emerged: a need for a computer tool supporting CHASSIS during requirement elicitation. This report presents an inital approach to a tool for CHASSIS. Included in the report are CHASSIS' background, related safety and security techniques and their limitations compared to CHASSIS. Further on, different approximations to a CHASSIS tool are presented resulting from industry input. The background, related techniques and input together form a proposed solution. The report continues presenting requirements of the tool as well as how these where implemented programmatically. An investigation of the tool and its abilities to fulfil the stated functional and non-functional requirements was carried out through a student experiment. The results of the experiments and other techniques utilised during the project is then evaluated and validated. A short summary and notes on further work concludes the report. | |
