Network Packet Inspection And Analysis Tools For The Tax System Design And Realization

With the development of network security technology, the research on the technology of network security is becoming an important subject.information systems' construction of zhejiang Local Taxation Bureau has great achievements in recent years. how to ensure information and network security become an important work. To identify each kind of intrusion behavior ,we designed the tools of packet detection and analysis.As an active security defense technology, network analysis and detection tools makes up for the weaknesses of traditional security technologies.The tools runs in the Linux operating system environment, The system is implemented by C language and function library libpcap that used to capture network data.that tools can capture real-time network data packet, and through statistical analysis of data packets into readable format, the tools Can account the network flux, and found the Network problems, it can also find the bottleneck and perform network Intrusion Detection. it can write down the daily record of network flow,etc.finally, the tools enumerates the practical application : checking port_scanning attacks, intercepted passwords, Protocol analysis.
