Address inquiring method, gateway or user device, and server

Abstract

The invention relates to network security technology and discloses an address inquiring method, a network node and a server. The address inquiring method comprises the following steps: acquiring an address which needs to be inquired, and acquiring address information of a neighbor network node of an adjacent geographical position; constructing an address security information inquiry request comprising the address; transmitting the address security information inquiry request to the server, and transmitting the address security information inquiry request to the neighbor network node of the adjacent geographical position according to the address information; and receiving an inquiry response comprising the address security information, and processing the address according to the address security information. By using the invention, the inquiry time can be reduced without increasing the operation cost of URL classification service providers and / or URL credit service providers.

Description

technical field [0001] The invention relates to network security technology, in particular to an address query method, a gateway or user equipment and a server. Background technique [0002] Uniform Resource Locator (URL: Uniform Resource Locator) filtering and URL reputation evaluation, as an important part of the unified threat management (UTM: United Threat Management) function, have attracted more and more attention. Response can block malicious websites when users send URL requests. In the true sense, threats are blocked before attacks occur, and user security is protected to a greater extent. [0003] Among them, URL filtering is mainly divided into two parts, URL local query (black / white list) and URL remote query. URL remote query and URL reputation evaluation are mainly to send the URL in the request to the remote query server for query and reputation evaluation when the user sends a URL request, and then the remote query server returns the evaluation result to the...

Problems solved by technology

[0005] In the research on the prior art, the inventor found that because the above method adopts the cluster technology and the content distribution network technology, the operating cost of the URL classification service provider and / or the URL reputation service provider is greatly increased, and with the URL With the further promotion of classification services and URL reputation evaluation services, operating costs will continue to increase, and operating investment will also increase significantly, which is not conducive to the widespread deployment of content distribution servers
