摘要
访问控制是一种重要的信息安全技术。为了提高效益和增强竞争力,许多现代企业采用了此技术来保障其信息管理系统的安全。对传统的访问控制模型、基于角色的访问控制模型、基于任务的访问控制模型等几种主流模型进行了比较详尽地论述和比较,并简介了有望成为下一代访问控制模型的UCON模型。
Access control is an important information security technology.To enhance benefits and increase competitive power,many modern enterprises have used this technology to secure their information manage systems.In this paper,several main access control models,such as traditional access control models,role-based access control models,task-based access control models,and so on,are discussed and compared in detail.In addition,a new model called UCON is introduced,which may be a promising model for the next generation of access control.
