Abstract

Role Based Access Control (RBAC) has been proved tobe effective for defining access control. However, in anenvironment where collaborative work is needed,additional features should be added on top of RBAC toaccommodate the new requirements. In this paper wedescribe a team access control extension model calledTMAC04 (Team-Based Access Control 2004), which isbuilt on the well-known RBAC. The TMAC04 modelefficiently represents teamwork in the real world. Itallows certain users to join a team based on their existingroles in an organization within limited contexts and newpermissions to perform the required work.
