Embodiment Construction

[0032] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0033] The object of network intrusion detection is data, so the source and accuracy of the data will directly affect the accuracy of network intrusion detection. If the network intrusion detection is only performed on the transmission data in the switch, the data source is relatively single, and the monitoring of the network environment of the internal computer work is not comprehensive enough, which is not conducive to timely detection of intrusion events. In addition, some intrusion events cannot be detected in time from network data, but computer system logs can record traces of network intrusion, and network intrusion events can be well discovered from these tra...

Abstract

The invention discloses a method, device and system for network intrusion detection. The method comprises the following steps: when a switch transmits data to an internal computer, backup data of the data is acquired from the switch, and system log information of the internal computer is acquired from the internal computer; and the system log information of the internal computer and the backup data are detected whether an intrusion event exists therein. According to the embodiment of the invention, the system log information of the internal computer and the network data are comprehensively utilized to carry out the network intrusion detection, and the accuracy and comprehensiveness of the network intrusion detection are improved. At the same time, according to the embodiment of the invention, the network intrusion detection method changes a convention method which progresses from the detection to the data transmission, and the network intrusion detection is realized while the timely transmission of the network data to the internal computer is ensure.

Description

technical field [0001] The invention relates to the technical fields of communication and computer, in particular to a method, device and system for network intrusion detection. Background technique [0002] The Internet (Internet) has developed vigorously to this day, and computer systems have developed from independent hosts to complex, interconnected open systems, which has brought great convenience to people in information utilization and resource sharing. The transmission and processing of various life information by the Internet has already become one of the important communication methods for people, and various attack incidents and intrusion methods have emerged one after another, causing a series of security problems. Therefore, in order to protect the security of the user's network environment and detect network intrusions in time, the network intrusion detection system came into being. [0003] Traditional network intrusion detection systems include firewalls, in...
