Design and Application of Radio and Television Network Security Architecture Based on Zero Trust Concept
Under the traditional paradigm,network boundaries are fixed,network protocols have native vulnerabilities,heavily rely on border security equipment protection,and the implementation of"connect before verify",these traditional protection concepts and technical architecture can no longer prevent the current increasingly high-end network attacks.This article conducts a deep analysis of the limitations of traditional boundary protection concepts and technical architectures,while elaborating on the zero trust concept,analyzing its advantages,and designing a zero trust SDP(software-defined Boundary)technical architecture for broadcasting and television.By applying the zero-trust SDP architecture to implement"Verify before connect",fine-grained access control and dynamic policy management can be achieved,continuously narrowing the trust domain and exposed surface,and hiding core assets and facilities.The technology architecture continues to evolve and evolve immunity,which can effectively defend against horizontal and vertical traffic attacks and effectively cope with complex and changeable security threats in the future.
