Network Applications Security Model Research And Applications

In this paper, the author discusses information security in theory and studies its application on Internet.Firstly.the author makes an analysis of the attacks on the Internet, within the framework of information security services ISO provides,the author researches on the information security technologies and mechanisms,especially the widely used ones like cryptograph, authentication and authorization.and improves them to some degree.Then,when weighting the technology's and mechanism's merits and demerits, plus cost, availability,complexity,the author presents a proposal of an internet application system information security model,consisting of three basic aspects: safe authentication,safe authorization and the security concerning the storage and transition of valuable information.The model aims at strengthening the security of medium-sized enterprise application system on the Internet.Finally,the author designs a Web application system based on the J2EE platform and does some system security testing,which testify the availability and security of the model.
