Invasion detection method and system

Abstract

The invention provides an invasion detection method. For network data presently transmitted to a user computer network, traversal matching for target attributes of the network data and test attributes of each node of a pre-established decision tree is firstly carried out, classification of the network data is determined, the pre-established decision tree is generated through processing training data of the network invasion data, and categories corresponding to nodes correspond to different invasion types. The method is advantaged in that whether the classification network data is invasion data is determined, network data invasion detection is realized, a detection process is more effective, and protection on a computer network of the user can be better realized.

Description

technical field [0001] The invention relates to the technical field of network security, in particular to an intrusion detection method and system. Background technique [0002] With the rapid development of information technology, computer networks have been widely used in various fields of life and work. People can use computer networks to carry out various daily activities such as network communication, games, and shopping. To a certain extent, computer networks have become an indispensable part of people's lives. [0003] With the popularization of computer network applications, computer network security has become a problem that people must face. Network hackers will take advantage of some security loopholes in the network protocol, write corresponding network data, invade the user's computer network, steal the user's relevant information, and cause losses to the user's interests. The inventor found through many times of practical research that there is no effective n...

Problems solved by technology

Network hackers will use some security loopholes in the network protocol, write corresponding network data, invade the user's computer network, steal the user's relevant information, and cause losses to the user's interests

The inventor found after many times of practical research that there is no effective network data intrusion detection method to detect the network data transmitted to the user's computer network, and thus cannot effectively protect the user's computer network security
