33 | 33 | There is one book [[http://www.amazon.com/gp/product/1580533701/ FKC03]] and a surprisingly large number of articles, papers, PhD theses, and web sites that touch on aspects of the design and implementation of role-based access control for ORBIT. Many of these sources are theoretical in nature, although some of the theoretical work includes implementation of tools to specify and check user-role assignments and constraints. Some of the papers address administrative issues. The following sources discuss RBAC implementation issues. |
