Distributed Intrusion Detection Method Based on Ant Colony Fusion Algorithm

Abstract

The invention discloses a distributed intrusion detection method based on an ant colony algorithm. The distributed intrusion detection method comprises the following processes: starting, initializinga distributed sensor, setting parameters of the ant colony algorithm based on attribute decision making, constructing a decision tree structure definition rule, setting ants on sensor nodes, determining a next node of data fusion, partially updating the information factors of an ant selection path, trimming the decision tree, and updating all information factors of the ant selection path, if an optimal path is not discovered, returning to the step of partially updating the information factors of the ant selection path; and finding the optimal path, creating the optimal path, and fusing data information. Compared with the prior art, the distributed intrusion detection method has the advantages of improving the detection efficiency of data intrusion in a network system, reducing the energy consumption and effectively guaranteeing the security of the distributed network system.

Description

technical field [0001] The invention relates to a network intrusion detection method, in particular to a distributed intrusion detection method based on an ant colony fusion algorithm. Background technique [0002] With the development and wide application of computer network technology, network intrusion incidents occur more and more frequently, causing more and more serious harm, and network security problems are becoming more and more prominent. Network intrusion detection has become a new research and development in the field of network security. hotspot. [0003] Intrusion detection refers to a security technology that collects information from several key points in a computer network or computer system and analyzes it to find out whether there are behaviors that violate security policies and are attacked in the network or system. Use the intrusion detection system based on intrusion detection technology to monitor the computer network and network-based systems, and ad...

Problems solved by technology

But in general, intrusion detection methods need to be further studied and improved. In the face of increasingly complex high-speed networks and increasingly novel intrusion and attack methods, detection accuracy and speed have become the main factors affecting the performance of intrusion detection systems. False detection and missed detection are still key and difficult problems in the implementation of intrusion detection
