Title Research and implementation of network
firewall technology
Abstract
With the rapid development of the Internet in the world, the Internet appears frequently data is modified, the information is stolen, the server is malicious attacks and other network security events, network security has become one of the issues that people are most worried about the use of computers in the Internet. So, how to solve the problem of network security is a trend of Internet development, network firewall is one of the more successful technology，it can effectively filter out network packets, release legitimate data, prevent illegal data, so as to monitor the network，and reduces the risk of the user being attacked in the Internet.
For firewall packet interception, I studied the basic principles and the firewall packet filtering technology, and for the personal firewall features, combined with knowledge of windows system, completed the design and implementation of a personal firewall to help solve network security problems for inpidual users. Firstly, a brief introduction to the topic, and then introduced the firewall packet interception of related technologies, and the design and implementation of a personal firewall module, and finally introduces the problem I encountered during the design and experience of the software design.
