Item type:Publication, Access status: without files , Evolution of security engineering artifacts: A state of the art surveySecurity is an important quality aspect of modern open software systems. However, it is challenging to keep such systems secure because of evolution. Security evolution can only be managed adequately if it is considered for all artifacts throughout the software development lifecycle. This article provides state of the art on the evolution of security engineering artifacts. The article covers the state of the art on evolution of security requirements, security architectures, secure code, security tests, security models, and security risks as well as security monitoring. For each of these artifacts the authors give an overview of evolution and security aspects and discuss the state of the art on its security evolution in detail. Based on this comprehensive survey, they summarize key issues and discuss directions of future research.Publicationtype: Book Part23 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Access status: without files , Empirical assessment of security requirements and architecture: lessons learned(Springer, 2014); ; ; ; Over the past three years, our groups at the University of Leuven and the University of Trento have been conducting a number of experimental studies. In particular, two common themes can be easily identified within our work. First, we have investigated the value of several threat modeling and risk assessment techniques. The second theme relates to the problem of preserving security over time, i.e., security evolution. Although the empirical results obtained in our studies are interesting on their own, the main goal of this chapter is to share our experience. The objective is to provide useful, hands-on insight on this type of research work so that the work of other researchers in the community would be facilitated. The contribution of this chapter is the discussion of the challenges we faced during our experimental work. Contextually, we also outline those solutions that worked out in our studies and could be reused in the field by other studies.Publicationtype: Book part27
