Discussion The Anti-Spam Technology Based On Behavior Distinguishes

The rapid spread of computer networks and the needs of modern paperless office, the email becomes people gradually carrying out one of the main intermediary that information exchanges, but the Spam being that up to but coming being in flood also Yue Lai Yue. Current situation the main body of a book is not worth specifically for white cloud academy Anti-Spam system function, before this one up to the minute Anti-Spam technology being in progress to pertinent theory of tradition Anti-Spam with the technology concentrating on distinguishing a technology to behavior on the basis discussing, have been in progress studying.First, the thesis has given a rubbish out the mail definition on the basis setting forth the Spam developing history. The marketplace prospect, that problem having expounded and proven choice detailedly having analysed the Anti-Spam product combining with the home and abroad Spam damage instance carry out background and significance studying. The agreement has carried out analysis on email system operating principle and email, has been in progress to the email sending and received system structure studying. The method creating means and resolving the Spam having summed up the current Spam on the cause basis that the Spam produces in analysis.History has carried out the secondary, the thesis on development of Anti-Spam technology summing up, current situation having analysed the current Anti-Spam technology. Various key technology in the Anti-Spam having studied in the world in the nowadays, these technologies have the the password technology, verify the inquiry technology, the photograph distinguishing a technology, keywords fliteration technology mainly, right and wrong name list fliteration technology, DNS opposite direction seek the technology, analyse be popular for most in depth to present owing to that the Beiyesi algorithm fliteration technology has been in progress. Advantages and disadvantages of these techniques make a personal point of view.The thesis has expounded and proven the Anti-Spam technology distinguishing owing to behavior, The mail data has carried out a thesis on the rubbish that the Guangdong Kemao Vocational College mail server intercepts and captures counting and analysing, and principle and feasibility have been in progress to the realization being a technology's turn finally to analyse in depth. has dispatched the data data that the behavior thought inquires into combining with the common Spam, the behavior having improved and forming one kind of Spam on basis distinguishing a model in thorough analysis one kind of tradition, distinguishes a model (SBD). Have worked out the model Spam prevention and cure tactics, have given the algorithm realizing that tactics out thought together according to the analysis to mail head attribute. Proceed to have designed one with a view of the school reality owing to the model Spam fliteration system scheme (SBD). When making use of the identification that a scheme in the mail carrying out a rubbish do not require that recipient all mail content carries out corresponding content matching, Adopt the stage communicating by letter in MTA to judge the mail coming to judge what be received if mail be a rubbish the method dispatching the mail if behavior accord with (SBD) model. The thesis has given a few realizing that scheme out the key algorithm. This design is completed to achieve the program's key algorithm., At the same time, the behavior recognition technology and shortcomings are described...
