Trust is an important problem in a community of interest (COI) built on top of service-oriented architecture (SOA). Furthermore, ranking services, data, and workflows in service-oriented applications is also important. This paper presents a role-based trust model to address these two problems. In this paper, users are classified into different roles in COI using role ontology (RO). The RO describes...
We advocate goal-oriented software security engineering to produce highly secure software in a constructive,provable and cost-effective manner. Our approach is to couple goal-oriented semi-formal requirements specifications with formal design and implementation. To this effect, we proposed FADES (formal analysis and design for engineering security)in as the first goal-oriented software security engineering...
With the increasing development of electronic commerce application, electronic commerce system security is facing the heavy challenge. To arrive at the goal of intensifying the behavior trustworthiness and controllability of electronic commerce systems, we focus on building the trustworthy model between electronic commerce system and user behaviors and strengthening the manageability of electronic...
With the increasing sophistication of attack techniques and scenarios, appropriate automated decision-making systems should be developed. This paper defines a new security language allowing to cope with attack scenarios through the representation of both attacks and security solutions in a single syntactic framework. A subsequent semantic analysis has also been introduced. To implement this reasoning,...
Acknowledged as important factors for business environments operating as virtual organizations (VOs), trust and reputation are receiving attention also in Grids devoted to scientific applications where problems of finding suitable models and architectures for flexible security management of heterogeneous resources arise. Being these resources highly heterogeneous (from individual users to whole organizations...
The importance of software security has been profound, since most attacks to software systems are based on vulnerabilities caused by poorly designed and developed software. Furthermore, the enforcement of security in software systems at the design phase can reduce the high cost and effort associated with the introduction of security during implementation. For this purpose, security patterns that offer...
