Research And Development Based On Access Control Technology Of Nuclearpower Project Management System Internal Data Security Policies

Access control technology is a important measure to protect enterpriseinformation systems internal data security, it can explicitly control the capabilities andscope which user access, the fundamental objective of access control technology is toprevent unauthorized users access to the resources of the system and restrict illegaluse of the legitimate users. With the rapid development of information technology, theidea of access control has penetrated into various fields of information system, hasbecome the main way to solve the system of internal data security issues.This article describes several very popular basic access control policy, analyzingthe access control technology needs and data security features in the nuclear powerproject management system, combine the most fundamental basic access controltechnology and the role-based access control technology, build the ComprehensiveAccess Control (CAC) model, and gives the basic concepts of formal definitions andconstraints description.In the practical application of the model, take the real nuclear power projectmanagement system for example, base on the nuclear power project managementsystem data security features and the characteristics of the task execution, discuss thetask process flow and dynamic permissions granted. Apply the access controltechniques to nuclear power project management system, it would be achieve secureaccess to internal data systems and process control, and enhance the security of thenuclear power project management system, improve system security access controlcapabilities.
