Autor: Sylvia L. Osborn, Matunda Nyanchama

Publikováno v: ACM Transactions on Information and System Security. 2:3-33

We describe in more detail than before the reference model for role-based access control introduced by Nyanchama and Osborn, and the role-graph model with its accompanying algorithms, which is one way of implementing role-role relationships. An alter

Role-based security, object oriented databases and separation of duty

Autor: Matunda Nyanchama, Sylvia L. Osborn

Publikováno v: ACM SIGMOD Record. 22:45-51

In this paper we combined concepts of role-based protection and object oriented (O-O) databases to specify and enforce separation of duty as required for commercial database integrity [5, 23, 24]. Roles essentially partition database information into

Role-based security

Autor: Sylvia L. Osborn, Matunda Nyanchama

Publikováno v: ACM SIGSAC Review. 11:11-17

User role-based protection presents a flexible (hence adaptive) means for enforcing differing ranges of security policies. It can emulate both mandatory and discretionary access control modes of protection. Role-based protection enforces the principl
