The present invention proposes a network filtering service system and method. The system includes: a terminal device, a gateway, a filtering server, and an application server; the gateway presets source address-based filtering configuration information pushed by the filtering server, and judges the received data Whether the source address of the packet falls into the filtering configuration information; the filtering server is used to receive the data packet forwarded by the gateway, identify the source address of the data packet, and filter the data packet based on the preset source address filtering rules; the application server is based on the filtering The subsequent data packets are processed for related services. In the present invention, the filtering configuration information based on the source address pushed by the filtering server is preset in the gateway, and according to the filtering configuration information, no address conversion is performed on the data packets receiving the specified source address, so that the filtering server can filter based on the source address The rules filter the data packet, thus solving the problem of incompatibility between the traditional gateway and the filter based on the source address.
Description
technical field [0001] The invention relates to the technical field of network communication, in particular to a network filtering service system and method. Background technique [0002] The Internet satisfies the supreme realm of "fast" and "unrestricted" that people have been pursuing for thousands of years, breaks through time and space, and realizes people's dream of freedom. It fits the original nature of people, and the degree of "freedom" achieved exceeds people's imagination. The openness of the Internet has allowed people to enjoy the freedom of unfettered access to various information, release of speech, but it has also brought about many information security problems. [0003] At present, in order to solve the problem of information security, filters are usually set up at the network boundary to filter information. Specifically, it can be determined whether to allow data packets to pass through according to the source address, destination address, port number, p...
