기존의 접근 제어 메커니즘인 강제적 접근 제어와 임의적 접근 제어는 무결성을 요구하는 상용 환경의 정보 보안에는 부족하여 이의 대안으로 직무 기반 접근 제어 (RBAC:Role Based Access Control)가 주목 받고 있으며, 직무를 수행하는 사용자의 의무 분리(Separation of Duty)에 대한 연구가 최근 이루어지고 있다. RBAC에서 사용자는 직무에 배정된 접근권한(Privilege) 만을 수행하여야 하는데 상호 배타적(Mutual exclusive)특성을 갖는 직무는 표현 및 접근 권한의 직무 배정과 수행에 있어서 어려움이 있다. 본 논문에서는 RBAC의 기본 특성을 분석하여 직무에 접근권한을 부여하고 사용자를 직무에 배정하는데 따른 안전한 접근 제어를 위하여 반순서 관계를 갖는 직무의 승계 속성에 따라 직무의 계층 형태를 분류하고, 직무에 배정되는 접근권한의 표현과 관리를 용이하게 하기 위하여 객체에 부여된 객체 접근권한을 분석하여 방향성 그래프를 이용하여 기본 접근권한으로 모델링한다. 접근권한 그래프(Privilege Graph)로 표현된 기본 접근권한에 직무를 배정하면 상호 배타적 직무의 접근권한과 의무 분리의 표현 및 관리를 용이하게 할 수 있다. 이를 기반으로 의무 분리를 포함한 RBAC의 안정성 특성과 접근권한 그래프를 이용한 직무의 의무 분리를 위한 직무 관리 알고리즘을 제시한다.

Due to people's internet use growth and proliferation of ubiquitous technology, the internet addiction is becoming a social issue. However, the current adults' self-diagnosis measure about internet addiction, the K-scale, is a normal diagnostic method, which it does not consider user characteristics. In this research, we will propose a new internet addiction diagnostic method based on users' non-duty internet activities by using some questionnaire items to collect users' basic internet patterns used on duty related or non-duty related web sites. Since we simply ask for the basic internet usage pattern to each user who does not like to check frankly questionnaire items in the K-scale, the proposed method can find some hidden internet addicts compared to the K-scale with the SPSS statistical analysis tool.

Today, management object using SNMP is not only covered network but also more privacy object like personal or billing data. To enforce security management, view-based access control model is introduced in SNMPv3. However, they are not designed to enforce more privacy object such as purpose and increase complexity of user management. Task-based access control can provide enhanced security service using purpose binding and leverage the complexity of user management using purpose of task.
