Local Taxation System Data Security And Intrusion Detection System Design And Implementation

The appearance of the computer network， has greatly facilitated people’s work and life.From80years since the last century， mankind has gradually entered the age of network. But， aspeople work and life style of diversified development， limitations of the traditional network ismore and more obvious， such as: wiring difficulty， network structures of large quantities， lineeasily damaged， high cost of maintenance. The people’s increasing demand caused severeconstraints network. To solve this problem the best way is to use wireless network. Comparedwith wired network， the wireless network has strong mobility， plug-and-play， flexible networkand traditional network do not have advantages， which has great extent to meet the diverse needsof people on the network. Specific to the local taxation system， the Local Taxation Bureau ofShandong province began in2008in the province’s local tax system to promote the use of wirelessnetwork， wireless network to realize data concentrated， carried out network declaration (doubleentrust declare)， electronic payment services， greatly enhance the efficiency of informationexchange.Safety is always the important problem in network communication. Currently， Shandonglocal taxation system of wireless network security measures mainly include the following severalaspects: first is the use of support service profile identifier32character SSID character of spreadspectrum sequence; The second is to use data encryption; In addition to using the open and sharedkey type identity authentication. But based on the local network system high sensitivity and lowfault rate and other characteristics of the above measures， and cannot be fully and effectivelyguaranteed in wireless network security. This paper on the current local tax system wirelessnetwork characteristics and security status of the analysis under the premise， combined withwireless network intrusion detection technology， designs a kind of strong pertinence， highintegration degree and strong management of the wireless network security system.
