We propose a hybrid approach for functional safety assessments of software. By hybrid, we mean that it is both goal-based and prescriptive. Recent studies advocate goal-based assessments based on structured, rigorous safety cases. The problem is that products also need to be certified against existing, prescriptive standards. This study suggests a way to integrate the prescriptive standard with a...
A large number of software security vulnerabilities are caused by software errors that are committed by software developers. We believe that interactive tool support will play an important role in aiding software developers to develop more secure software. However, an in-depth understanding of how and why software developers produce security bugs is needed to design such tools. We conducted a semi-structured...
Ruby on Rails (RoR) has developed rapidly since the release of RoR 1.0. With the popularization of RoR, more and more development tools supporting RoR emerged. In this paper, we compare and analyze several main RoR development tools based on our experience of using those tools, which can help RoR developers select the most suitable tools according to their technical background and programming preference.
In this paper, a data-driven model based on Bayesian Networks (BNs) is presented for the risk analysis of software development. The modeling process consists of three phases: BN initialization, conflict analysis, and risk monitoring and analysis. Using new project data obtained from the process of software development, the model can continually estimate risk probability, identify the sources of risk,...
