Abstract

The invention provides an accessing abnormity detection method and a system based on a Markov model, which relate to the technical field of network security. The method comprises the following steps:when detecting that a user accesses a target page to be detected through a source page, drawing an access route map of the target page to be detected, wherein, the access route map comprises a targetaccess route; when the user accesses a target page to be detected, the access route map comprises a target access route; calculating the route reference value for the destination access route, the method of the invention improves the detection efficiency of the abnormal access route and alleviates the technical problem that the detection efficiency of the prior network security technology is low when the abnormal access detection is carried out.

Description

technical field [0001] The invention relates to the technical field of network security, in particular to a Markov model-based access anomaly detection method and system. Background technique [0002] The Internet has been involved in all aspects of people's lives, brought great convenience to people's lives, and has become an indispensable part of people's lives. However, at the same time, security incidents caused by hackers using the Internet have also been exposed frequently, which has brought specific threats to the application and development of the Internet. With the multi-terminal and concealed means of intrusion, the speed of transmission increases, the scope of influence expands, and the harm of intrusion increases, security issues have become an urgent problem to be solved in the development of the Internet. There are many existing Internet access anomaly detection methods, which are roughly divided into the following: access anomaly detection methods based on ac...
