Abstract

The invention discloses a service recognition method and device for multi-granularity feature analysis. The service recognition method based on multi-granularity feature analysis comprises the following steps: host survival detection is carried out, so that survival hosts are obtained; performing open port scanning on the surviving hosts; and performing service recognition on the open port by using a multi-granularity feature analysis method. According to the service recognition method based on multi-granularity feature analysis, feature analysis is carried out on the port return information through the composite strategy, high-efficiency fingerprint database matching is carried out, and compared with the prior art, the method is more accurate, and the result is more detailed.

Description

technical field [0001] The invention relates to the technical field of penetration testing, in particular to a service identification method for multi-granularity feature analysis and a service identification device for multi-granularity feature analysis. Background technique [0002] With the comprehensive construction and rapid development of network informatization, more and more key basic information facilities are carried on the enterprise network. Although enterprises pay more and more attention to the security of important network assets, they often fail because of insufficient protection of some inconspicuous assets. In place, the attacker breaks through the defense line, which brings huge losses to the enterprise. At present, there are many technologies for host service identification, such as judging by default port and judging by banner information. However, there are varying degrees of deficiencies in the accuracy and detailed information description of the serv...
