Toward an improved RBAC model for the organic organization

Abstract

For the smooth and efficient business within the organization of an enterprise today, it is required to utilize the information processing system by using computers, for which the most important factor for the security of organization is the access control for resources. Many access control methods have been studied including DAC and MAC. The role based access control (RBAC), which is based on role, is spotlighted today, and many models have been studied. However, most RBAC models support the bureaucratic organization structure that is mechanical, static, ordinary and of clear vertical relationships. This paper studies the characteristics of the adhocracy organization and the RBAC model to support the adhocracy organization structure that is organic, dynamic and extraordinary such as matrix organization or task force team.
