基于角色访问控制在FCS系统中的应用分析

Discussion of RBAC Technique Applied into FCS6

本文分析了基于角色访问控制技术(RBAC)的基本原理和特点;对现场总线控制系统的系统结构和安全问题作了讨论。依据对二者的分析,结合彼此的特点,文章最后提出了一个化肥企业FCS系统中基于角色访问控制技术的安全应用模型,认为控制系统、实时数据库、数据库安全技术相结合,将具有广阔的发展前景。

Role Based Access Control (RBAC) technique are given such as its abstract model and its work principle are discussed in this paper.Then the architecture and security problem of the Fieldbus Control System (FCS) are generally analyzed.Combining the RBAC technique and the characteristic of FCS together, an application model and data model are developed to resolve security of FCS.The combination of control system,real-time database and database security techniques will be greatly developed.
