Design And Implementation Of Firewall And Intrusion Linkage For Tax Information System

Tax is both a major source of sate revenue and an important part of our economy. It is taken from people and given back to people. Because the traditional tax measures can’t meet the need of social development any more, the tax informatization becomes the inevitable selection of social development and improvement, and it also becomes the important work of provincial land tax system to construct tax private network.Since the date of construction of our tax private network, it has become the core part of tax informatization, of which security building has been a key part. According to years of construction of network and information security protection system, the tax information system security capabilities have been extremely strengthened. With the expansion of the network system and the improvement of various application systems and the rapid development of science and technology, new demands have been put forward to the tax information system security.In this Dissertation with the linkage of the firewall and intrusion detection system as the research direction, it analyses the existing problems of firewall and intrusion detection system, and how to improve the security of network through the linkage of the firewall and intrusion detection system, and the actual test at the end to prove that the system for private network actual effects.This Dissertation embarks from the project background, firstly introduced the safety status of the internet, and then introduced the firewall, intrusion detection and the linkage of the related content, and designs the tax private network security protection structure. It was tested in a specific environment once again, after that the results were analyzed. Finally, the linkage of the firewall and intrusion detection system have been analyzed and evaluated. Meanwhile, the improvement plan of the next step was pointed out.
