Campus Net Network System Of Bohai Shipbuilding Vocational College

Develops rapidly along with the information technology, the society strengthens day by day to the computer network dependence, the people while enjoy huge benefit which the network brings, is testing sternly faced with the network management aspect. Network management including networking application and network security design, the network security designs including the network time security. Network oneself adopts guards against attack measure, as well as and so on investigation evil intention user attack.Completes along with the network popularization and the campus network, the network management system becomes the school campus net to construct, manages essential part of. Develops this system to use tool: front end behind PowerBuilder Sql server data operates platform Windows2002.The present paper first mainly introduces the correlation software knowledge , then introduction service aspect knowledge, when detailed introduction module and concrete programming meets question solution process .When correlation knowledge introduction, mainly introduced PowerBuilder Sql server database relations, PB programming.The network security is when any network construction first must consider important question, institute network environment more complex, user's technical level is all high, the curiosity quite is strong, the network security even more is worth paying attention to.TCP/IP network itself existence very many security loophole, Is used very easily by some malicious user and implements the attack, or illegal takes the network resources, encroaches upon other users the legitimate benefit, even causes the entire network system to collapse. Any network equipment all must first have enough protecting oneself with guard ability.This design has applied the virtual local area network technology, the invasion monitor technology, the identification authentication technology, the data encryption technology and firewall technology.Because the network security is not merely a merely technical question, the only technical factor is not impossible to guarantee the network security, therefore, the management and the technology and so on the various factor. The network security system is by the network security legal framework, the network security management system and the network security technology system is composed, these three is complements one another.This article based on above various modules design, has given the Bohai Sea Ships Professional Institute campus net network management system design and the realization plan. And summarized this system merit and the insufficiency, has pointed out the next step research direction.
