Embodiment Construction

[0032] The schematic diagram of the existing application identification scheme is attached figure 1 As shown, on the one hand, with the rapid increase in the number of applications based on browser (including WEB1.0 and WEB2.0) technologies, the scale of the state machine for feature matching obtained by compiling the features of various applications Rapid growth, the memory space it occupies is also increasing; on the other hand, the unknown traffic to be identified is also increasing. Both of the above two aspects lead to low identification efficiency and performance when matching unknown traffic, making it a bottleneck for network security management. When the security device cache and CPU processing resources used for application identification are exhausted In this case, some of the packets to be matched will cause network delay because they cannot be processed in time, which seriously affects the user experience; and if matching is abandoned in order to avoid delay, the ...

Abstract

The invention discloses an application identification method and an application identification device which are used for solving the problem in the prior art that the identifying and matching performances of a WEB2.0 (an internet mode before 2003) application are not high. The method comprises the following steps of carrying out DNS (domain name server) decoding on a DNS request message in the flow of an unknown network as well as a DNS response message corresponding to the DNS request message, so as to obtain an IP address corresponding to a pre-set WEB2.0 station realm name; dividing the flow of the unknown network to obtain a source address or a destination address as the flow of the IP address; inputting the divided flow of the unknown network into a first state machine for characteristic matching; outputting a matching result of the first state machine; and if the matching result includes an identification of the WEB2.0 application, then determining that the identification is the identification of the WEB2.0 application corresponding to the characteristic of the divided flow of the unknown network. As the scale and the flow to be identified of the state machine, as well as the matching times, are reduced, operation resources are saved, and the performance and the efficiency aiming at the WEB2.0 application identification are improved.

Description

technical field [0001] The invention relates to the technical field of computers and networks, in particular to an application identification method and an application identification device. Background technique [0002] With the popularity of the Internet, Internet technology has also undergone rapid progress. WEB2.0 is an Internet application construction technology that has emerged in recent years and has been widely promoted. WEB2.0 is relative to WEB1.0. The main feature of WEB1.0 is that users receive information from the webpage presented through the browser, such as reading news in the news webpage; In the process of user interaction, the user is not only the viewer of the website content, but also the producer of the website content, that is, the user is no longer just a reader of the web content, but also the author of the web content. In terms of working mode, WEB2.0 enables the relationship between users and websites to develop from simple "reading" in WEB1.0 t...
