Analysis And Implementation Of Efficiency Network Filter Based On Static Taint Seed

With the rapid development of Internet, online banking and e-commerce web-based financial services is one step to replace the daily financial operations. But with the increasing complexity of network topology, network security issues are also increasingly prominent, the entire discipline of computer science and technology the focus of attention.Intrusion Detection System is a network firewall and other traditional Internet security protection measures in the comparison of the latest and most efficient filtration system. Intrusion detection technology can compare the characteristics of existing computer database to identify malicious network attacks and only attack packets containing discarded. Intrusion detection has become an increasingly important way to protect one of network security, has also been widely used. With the Internet, intrusion detection of the gradual deepening of intrusion detection technology in the network security research plays an increasingly critical role. Meanwhile, in an increasingly complex network security aspects of the Internet also accept greater challenges, such as how to improve intrusion detection system, contrast detection rate, told the network communication to meet the requirements; how to reduce the false negative intrusion detection systems and false alarm and comparison of intrusion detection system to improve detection accuracy, thereby improving the safety performance of the whole system and so on.With the development and popularization of computer network, our working and living environment has been greatly improved, the Internet provides a more convenient way to work and makes life easier. However, everything has its other sides, hackers often make use of the vulnerable networks to attack innocent victims frequently. Facing these problems, we were used to passive defense, such as taking the patch, installing a firewall, reinforcing the system, which can only solve the problem temporarily.
