Network Security Research And Network Security Project

Along with the technological development of computer and network system, electronic office system is widely used from all walks of life in recent years. With the wide application of electronic office system, the network system develops more quickly. The small businesses have LANs. The large and medium-sized enterprises build MANs, even WANs across the globe.With the widely development of network system, various threat to the network system security become more and more heavily. Some people maybe remember yet, the virus such as Blaster has infected the network system over the world only in 8 minutes. The malicious acts caught by the network defensive system become more dangerous. Some malicious software have involved crimes. Now, the malicious software can be used to filch secret information, send junk e-mails, personate somebody else illegally, and so on. They become more difficulty to remove, hide more deeply, contain more tricks. Above all, the threat to the network system security have manifested mainly in authenticated access, personate somebody else illegally, destroy the integrality of data, disturb the normal running of system, spread virus over the network, eavesdrop via communication circuit, and so on.Fortunately, more and more solutions can be chosen by us to resolve the threat, more and more packs for the system can be got. The windows systems have real time update, the linux systems have automatic update tools, almost every software applications can update themselves by supplied tools. The network managers have more methods to defend the hacks.In the network system project, we have got these safety precautions. We should not only know these theories but also how to apply them to practice.
