The computer network development present situation characteristic is:Interlocks, is high speed, the intelligence and a more widespreadapplication. Internet covers one of global information infrastructures, saidregarding the user, it likes is a huge long-distance computer network.The user may realize the global scope email, the electronictransmission, the information inquiry, the pronunciation and thepicture correspondence service function using Internet. In factInternet is (ROUTER) realizes Internet with the router which manylong-distance nets and the local area network interlocks. It to willimpel the world economics, social, the science, the culturaldevelopment to have the inestimable function. While interlocks which the net develops, high speed also brings topeople more and more many attentions with the intelligent networkdevelopment. The high speed network technological development displaysin wide band synthesis service data networking B-ISDN, the framerelaying, asynchronous mode of transmission ATM, the high speed localarea network, exchanges local area network and in the virtual network.Along with network scale increasing with network service functionincreasing, the various countries develops intelligent network IN(Intelligent Network) the research. The computer network technology rapid development and the widespreadapplication will certainly to the 21st century economies, theeducation, technical, the cultural development to have the importantinfluence. In the network security aspect, the virus, the wooden horse, malicioussoftware, the hacker and so on are more and more many, the networksecurity has received the huge challenge. Every day accesses the netin us in the process, our computer all receives multitudinous viralthe attack. All is loaded with 杀毒 software and the firewall for inthis ours computer. Even if is this our computer is not 100% security.Because 杀毒 software and the firewall are only can kill the knownvirus, the wooden horse and prevents some known formses of defensiveaction. Therefore our computer still could frequent receive thehacker, virus's attack. But for ours computer can the as far as possible reduced such harm, weor have to install 杀毒 software and the firewall, and frequentlyrenews to it, but also has on wants immediate is the operating systemhas the patch, reduces in the system the loophole. I thought the computer network the prospects for development aremagnificent, because the information time cannot leave the computer,cannot leave the computer network. In the later day, the computernetwork will be able to have a greatly quicker development to satisfysocial the need. Regardless of which time, the historical development always doesexpedite its cultural shape along with it development change, thenetwork also similarly is unable to run away to this principle.Follows the modern network digitization technology rapidly to rise,the network starts unceasingly to attack our cultural consciousness.After the nearly ten years development evolution, the network alreadyobtained more universal acceptance with the approval, became thehistory of literature a historical pitch point. At present, theliterature website, individual main page, the gateway websiteliterature frequency channel, the electronic literature periodical aswell as flood to each big literature studies the frequency channel原创 literature competition, forum writing and abundant guestwriting proliferates in network each quoin. "Young Soldier Legend"pushes onward hundred searches years ten big key words from 2005, "thenonsensical talk" the series is lucky to 2006 to the network, more andmore many networks write the pet which the hands becomes thepublishing circles, a wave wave network reading and the publicationraging tide, are demonstrating today network literature revelry. Thistime, then will appear regarding the present network literaturepresent situation as well as future development tendency some pondersespecially importantly. The network security is refers to the network system in the hardware,software and its the system data receives the protection, is not been accidental or the evil intention originally thus is destructed, thechange, the revelation, the system continuously reliably normallymoves, the network service does not sever. Now the global universalexistence lacks the network security consciousness the condition. Thepeople are setting up a network time, certainly has not realized thenetwork security the importance. This causes the majority network tohave the congenital security loophole and the safe threat. Thereforethe computer security question, should look like each each householdthe fire protection security question to be same, achieves the guardto not however. Even could not think you also can become the goaltime, the threat already appeared, once occurs, frequently is caughtoff guard, causes the enormous losses. Group of computer instructions or the procedure code in the computerprogram which the computer virus is refers to the establishment orwhich inserts the destruction computer function or the destructiondata influence computer use and can oneself duplicate. For thecomputer security, we must complete the virus protective measure: One,must install the legal copy 杀毒 software, the different networkoperating system corresponds the different type to guard against杀毒 software. ; Two, on the hardware prevented rewrites BIOS;Three, when uses carrier and so on others' floppy disk, USB plate,must first carry on the anti-virus inspection; Four, accesses the netwith the networking in front of should first start guards against杀毒 software; Five, must make the backup to the system importantmaterial; Six, promptly to guards against 杀毒 software to carry onthe promotion; Seven, formulates the corresponding managementstrategy, the unification anti-poison strategy, the centralismanti-poison management and the maintenance for is best. The computer network development could be does not have may limit thequantity,
