Intranet and extranet synchronous security login authorization method

The invention discloses a synchronous secure login authorization method for internal and external networks. Compared with the prior art, the method has the advantages that a model is provided, and the method is characterized in that a zero-trust thought is adopted to construct a secure login authentication system, that is, any person, equipment, system and application inside and outside the network are not trusted under the default condition; intranet and extranet synchronous login is realized, but data and requests of trusted nodes are received on the basis of identity authentication and authorized access control, so that the security of intranet and extranet synchronous login can be further improved; through the operations, the system can know whether the received request comes from the credible site or not, the possibility that an attacker fakes the request to cheat the system is further reduced, even if the attacker takes down the extranet system, the attacker is difficult to further sniff open interfaces
