面向设计过程的项目管理系统安全访问模型

Process Oriented Project Management System Access Control Model

信息访问控制是信息共享系统不可缺少的功能。在项目管理系统中,协同的工作环境需要一种新的访问控制模式。文中提出了一种新的静态访问控制模型和动态访问模型相结合的安全模型,并给出了一种有效的缺省授权机制,大大简化了的系统的授权和访问控制。

Access control is an indispensable part of any information sharing system. Collaborative environments introduce new requirements for access control. This paper developes a new access control model that brings the static access control mode and dynamic access control mode together, based on the analysis of process model, organization model and resource model on project management.
