| With economic prosperity and people’s living standards improved significantly, automotive market in China annual sales increased rapidly. To meet consumer demand and achieve the company’s long-term development and to capture the market opportunities in a short time, major car brands are accelerating the construction of sales network. It is convenient to use sales network to attacks more and more, car sales network security is facing various threats, the security issue is that people must be addressed.Traditional firewalls and other security technology, intrusion detection as a proactive security protection technology, real-time protection of computer systems from internal and external network attacks, misuse and other behavior. Existing intrusion detection techniques as a late start, the study conducted not deep enough, there are still false positives and false negatives, detection and analysis methods are simple, proactive defense capacity is low and other issues, to complex environmental car sales network adaptability is obviously insufficient, unable to meet the much sought after high network quality of service.This article from a macro perspective on the existing car sales network on the basis of full investigation of the existing intrusion detection system framework and key technologies based on full consideration of the proposed car sales network for security intrusion detection system framework. Through the open source Snort intrusion detection system, packet capture module and its matching module conducted in-depth research, and its current shortcomings are analyzed, proposed improvements. Verified by experiments show that the improved scheme is not only to improve the processing speed, and can improve the detection accuracy. Finally according to the data processing, design experimental environment, the model false positive rate, detection rate and the current status of the network fitting, verify the design of this model has a certain rationality. |
