Distributed network resource security access management system and user portal

A distributed network resource security access management system, comprising:

• a policy management module, a user management module, a user access module, a resource management module, and a resource access module, wherein:
• the policy management module is in a communication connection with the user management module, the user access module, the resource management module, and the resource access module, and is used for managing policy information for users to access network resources;
• the user management module is used for managing user information and transmitting the user information to the policy management module;
• the user access module acquires user information, resource access module information and policy information associated with the user access module, as well as a connection relation between the resource access module and the network resources, from the policy management module, receives a first access request for a target network resource initiated by a user by means of a user terminal, converts the first access request according to the connection relation to generate a second access request, and transmits the second access request to the corresponding resource access module;
• the resource management module is used for managing the network resources and transmitting the network resource information and the connection relation between the network resources and the resource access module to the policy management module;
• the resource access module acquires user access module information and network resource information associated with the resource access module from the policy management module, receives the second access request, converts the second access request to generate a third access request, and then sends the third access request to a target network resource server.
