Companies today manage business information with computer systems and many users access it for their job functions. Companies need security mechanisms to effectively protect important information. Moreover they need to minimize the interruptions from security mechanisms that cause delays in the execution of business activities. It is a difficult problem. In this paper we analyze the requirements of access control in enterprise environment and propose classifications for job functions. We propose a improved access control model for enterprise environment through integration of role based access control and activity based access control model.
