Embodiment Construction

[0014] Such as figure 1 As shown, the present invention discloses a network intrusion detection system, including a message receiving module 1, a message analyzing module 2, a message sending module 3 and an access module 4, and the access module 4 is used to extract the accessed datagram match the information of the data packet with the preset processing strategy, and send the matched packet to the packet analysis module 2.

[0015] The network intrusion detection system also includes an alarm module 5 and an event storage module 6; wherein,

[0016] The alarm module 5 sends a warning to the message receiving module 1 according to the analysis result of the message analysis module 2;

[0017] The event storage module 6 performs statistics and analysis on intrusion events and attack behaviors in the network.

[0018] The access module 4 includes a protocol decoding unit, which is responsible for decoding captured messages and matching the decoded messages with preset process...

Abstract

The invention relates to the technical field of network intrusion detection, and especially relates to a system for detecting a network intrusion, comprising a message receiving module, a message analysis module, a message transmission module and an accessing module; wherein the accessing module is used for extracting information of accessed data message, matching the information of the data message with a preset processing strategy, and transmitting matched message to the message analysis module; the system also comprises an alarm module and an event storage module; the alarm module is used for sending an alarm to the message receiving module according to an analysis result of the message analysis module; and the event storage module is used for performing statistics and analysis on intrusion events and attack behaviors occurring in a network. The system of the invention can effectively detect network intrusion behaviors, can solve the problems of large system overhead and limited performance of an IPS (Intrusion Prevention System) in the prior art, and can improve security of the network.

Description

technical field [0001] The invention relates to the technical field of network intrusion detection, in particular to a network intrusion detection system. Background technique [0002] At present, the risks and opportunities of network intrusion are increasing sharply. Designing security measures to prevent unauthorized access to system resources and data is a very important and urgent problem in the field of network security. At present, it is not realistic to completely avoid the occurrence of security incidents. What network security personnel can do is to try their best to discover and detect intrusions and intrusion attempts, so as to take effective measures to plug loopholes and repair the system. Such research is called intrusion detection, and the system developed for this purpose is called an intrusion detection system. [0003] Intrusion detection is a reasonable supplement to the firewall, which helps the system to deal with network attacks, expands the system's...
