Well, when I google this, I find a lot of good examples of studies that have been done, like this one: portal.acm.org/citation.cfm?id=1522762[/url]
So, now your challenge is to carefully read every study that has been done in the past few years on this subject. Each study will probably have a literature review that explains the current state of understanding. You will probably find a study, similar to the one you have in mind, that SUGGESTS further research with attention to particular aspects of the process. By reading what others have learned, you'll discover what the best focus is for your research at this particular time in the history of Network Intrusion Detection Systems and Support Vector Machines.
