SDP Security Control Technology Based on Zero Trust

With the development of the Internet, cloud computing, big data, distributed and other technologies have been widely used, and the scale of the network continues to expend and increase in complexity. The traditional 4A system has limited management and control capabilities in the face of complex networks, and the existing security risks and information security issues are key issues that must be resolved. In the 4A system, the concept of zero trust is applied, and the characteristics of continuous authentication and dynamic authorization of the zero trust network are used to establish an efficient 4A system to meet the security requirements of managers for network security and resource management. This paper discusses the comparison between traditional security management and control methods and the introduction of zero trust/ Software Defined Perimeter (SDP), the system in terms of authentication and access control, and the specific practice of applying SDP security products to enhance protection capabilities.
