Access control models implement mechanisms to restrict access to sensitive data from unprivileged users. Access controls typically check privileges that capture the semantics of the operations they protect. Semantic smells and errors in access control models stem from privileges that are partially or totally unrelated to the action they protect. This paper presents a novel approach, partly based on...
Access control vulnerabilities in web applications are on the rise. In its 2010 "Top 10 Most Critical Web Applications Security Risks", the OWASP reported that the prevalence of access control vulnerabilities in web applications increased compared to 2007. However, in contrast to SQL injection and cross-site scripting flaws, access control vulnerabilities comparatively received much less...
A Trust and Context based Access Control model (TCAC) is proposed in this paper, which integrates trust value and context information of users into traditional role based access control. TCAC is flexible and dynamic to limit the authorizations to users. Verification and analysis of access control policy can help us understand the security requirements and states of systems. Colored Petri Net (CPN)...
