Embodiment Construction

[0031] Usually we access web pages through URL access (destination address). The process is that the terminal sends the URL to the DNS server in the IP address setting, DNS parses the URL, and returns the corresponding IP address to the terminal URL. The terminal finally passes the IP address to establish a connection with the website.

[0032] figure 1 Take the client in the information extranet calling the service interface in the information intranet as an example, and vice versa. Such as figure 1 As shown, the service interaction platform system based on the isolation of internal and external networks of the present invention consists of three main parts, which are the internal network node 2 located in the information internal network, the external network node 1 located in the information external network, and a database server 3 .

[0033] The external network node 1 and the internal network node 2 are connected to a database server 3 , and the internal network node 2...

Abstract

The invention discloses a service interaction platform system based on internal and external network isolation. The system comprises an external network node and an internal network node, the externalnetwork node and the internal network node are connected with a database server, and the internal network node and the external network node operate a database in the database server for data interaction; the external network node in communication connection with a request client through an information external network, and the internal network node in communication connection with a website server through an information intranet; the request client accesses the website server through adoption of the isolated interaction method; and all the accesses of the request client employ the external network node to receive information, the external network node sends the access information to the internal network node which is used to replace the request client to access the website server and send the return information of the website server to the external network node, and finally, the external network node sends the return information to the terminal. The process can effectively isolate the terminal from the intranet website server for direct access and can perform filter for the access data so as to improve the information safety level.

Description

technical field [0001] The invention relates to the technical field of computer network information security, and more specifically relates to a service interaction platform system based on isolation of internal and external networks. Background technique [0002] At present, in order to ensure the security of network information, electric power companies usually divide the information network into information intranet and information extranet. The information intranet is the enterprise's own internal network, and the information extranet is the Internet. The internal and external networks of information are either physically isolated without any connection. Either use a security isolation device to isolate, either way will cause the data between the internal and external networks to be unable to be transmitted, and external network clients cannot access the website server on the internal network. Contents of the invention [0003] In order to solve the above problems, t...
