Embodiment Construction

[0047] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all of them. Based on the embodiments of the present application, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present application.

[0048] In order to avoid repeated identification of equivalent sessions when identifying applications, save system resources, and improve system performance, an application identification method is designed in the embodiment of the present application. to obtain the list of feature characters containing the destination IP, and the set of feature characters set corresponding to the destination IP, and match the list of feature characters with th...

Abstract

The embodiment of the invention discloses an application identification method and an application identification device, the method comprises the following steps: performing characteristic character extraction for a to-be-identified session, obtaining a characteristic character list, wherein the characteristic character list at least comprises a destination IP of a server; acquiring a characteristic character set which is set corresponding to the destination IP in the characteristic character list, and respectively matching the characteristic character list with each application character listcontained in the characteristic character set to obtain a matching result; based on the matching result, judging whether the matching result represents successful matching, if so, determining an application which is set corresponding to the characteristic character list; otherwise, acquiring an associated IP which is set corresponding to the destination IP, further obtaining an associated character set which is set corresponding to the associated IP, and based on the characteristic character list, the associated IP and the associated character set, determining the application which is set corresponding to the characteristic character list. So, repeated identification of various equivalent sessions is avoided, system resource is saved, and system performance is improved.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular to a method and device for identifying an application program. Background technique [0002] With the development of Internet technology, in order to improve the security of the network, port identification, Internet Protocol Address (Internet Protocol Address, IP) identification, Deep Packet Inspection technology (Deep Packet Inspection, DPI) are usually used based on the session between the application and the server. ) identification, deep flow inspection technology (Deep Flow Inspection, DFI) identification, or protocol decoding and other technologies to identify applications, and then perform network security operations such as screening applications based on the identification results. [0003] Wherein, the port identification and IP identification are to identify the application program through the port and IP of the application program, the port and IP...
