广西大学硕士学位论文RESEARCH 广西大学硕士学位论文 RESEARCH OF CORBA．BASED INTRUSIoN DETECTION SYSTEM ABSTRACT While we enjoy all kinds of benefits that computer network provides US，more and more network intrusion affairs also dump ns．So network security study is very significance．Researchers firstly used various passive ways to protect their computer networks，which produces many firewall solutions．Now general view is that only firewall solution solve indeed network security．Thus many of researchers focus intrusion detection system This paper mainly studies the following problems It analyses merit and flaw of many detection techniques that used by intrusion detection systems that we can select suitable method for system． The system structure，particularly of distributed intrusion system， is analyzed．In this part of the paper,we have studied three prevalent middleware techniques．We draw the conclusion that CORBA bring intrusion detection system more merit．It is very important that CORBA make intrusion detection system having extensibility by its property of software bus．What’S more，we provide solution of 广西大学硕士学位论文 广西大学硕士学位论文 intrusion detection suitable for high—speed network In view of above，we design and implement prototype system of intrusion detection．Our system communicate flexibly control and response unit with distributed detectors．The system had real ized fair extensibility．Together with naming service of CORBA， communication control and response unit with distributed detectors is more convenient．Through this system，people may exclusive name to manage distributed detector,which is importance when new detector is added to this system．Without changing and recompiling control and response unit，system may manage new detector long new detector accords with originally IDL design． Keyword：intrusion detection system IDS distributed system CORBA network security 广西大学硕士学位论文第一章绪论 广西大学硕士学位论文 第一章绪论 1．1问题的来源 近年来，Internet正以令人难以置信的速度在飞速发展，网络安全越来越引 起人们的重视。在网络安全方面人们最初想到的方法是“防”，于是最先发展起 来的安全技术是防
