Kerstin P??iger,S?hnke Vosgerauthough, traditional RBAC does not easily express application-level security requirements. For instance, in a medical records system it is difficult to express that doctors should only update the records of . patients. Further, traditional RBAC frameworks like Java’s Enterprise Edition rely solely on

However, these extensions introduce complexity and have not yet been combined to simultaneously add both state . visibility control to traits..This paper r

To get familiar with how those API methods are used, programmers often exploit a source code search tool to search for code snippets that use the API methods of interest. However, the returned code snippe

Existing applications contain valuable examples of such steps, except that locating them in the application code is often challenging. We propose the notion of ., which summarize the necessary implementation steps, and an approach to automatic ext
