Abstract

This paper applies RBAC policy for solving on the security problems when it will be operated several business on the distributed environments and designed Extended RBAC (ERBAC) model that it is possible to manage security systems on the distributed environments. The designed ERBAC model is based on RBAC96 model due to Sandu et al and added role delegations. Therefor, the designed ERBAC model have the advantage of the following . it can be processed of business without interrupts and implemented server system without modifying its source code, high migration, easy and simple of secure managing.

본 논문은 분산 서버 환경에서 다양한 업무를 운영하려고 할 때에 발생되는 보안상의 문제를 해결하기 위하여 RBAC(Role Based Access Control) 기법을 이용하여 분산 환경에서 운영 가능한 역할 위임을 위한 확장된 RBAC(Extended RBAC: ERBAC) 모형을 설계하였다. ERBAC는 기본적으로 Sandhu 등이 제안한 RBAC96 모형에 역할 위임부분을 추가하였다. 따라서, 역할을 위임하기 위해 ERBAC를 이용하면 사용자 수준의 역할 위임이 가능하여 업무의 중단 없이 영속성을 보장할 수 있다. 또한 분산 서버의 소스코드 수정 없이 구현 가능하고, 이식성이 높으며, 보안 관리가 단순하고 용이하다는 장점을 갖는다.
