New Type Of Active Protection Module Network Security

Accompanied by the rapid development of computer science and information technology, computer network as a key information exchange means originally applied in such areas as industry, agriculture and national defense has increasingly infiltrating into other fields in social life. In view of the significance of the computer network, people must take sufficient measures to ensure the safety of our network in every respect and thus to protect free information exchange from undue disturbances. Building and applying effective fireworks is the first line of defense in realizing this object. The subject of this article mainly involves in the analysis of security techniques in assembling firewalls and in the introduction of different formats of system structures. On the basis of this theoretical knowledge, I design a new type of firewall that combines the feature of packet filtering with that of proxy on the customer level and that, at the same time, overcomes the inefficiency of proxy service and the shortcomings of packet filtering in identifying forged addresses. The firewall devised in this article is reinforced in content filtering and self-defense by employing active safety mechanism in module design. Considering flaws of other types of firewalls, I integrate the firework techniques with the security supervision system of networks in aim to improve the ability of fireworks to foil the invasion of hackers or computer bugs and to supervise the whole system at any time. Because network security is a relatively fresh topic for many people in our country and because the varieties of means adapted by hackers have been changing constantly, this active protection module for network need further improvement.
