Intrusions differ too much from spam for this to be accurate!'' After reading your thesis, my ideas were changed. This work is certainly very interesting, and I encourage you to continue its development. Certainly one thing that would be desirable that I did not see listed in the improvements section (and many other IDS systems, such as Bro) would be the ability to carry out some action (instead of pure reporting) based upon behavior; this would allow for IDS as well as IPS behavior. I'm quite interested and impressed by the work you've done here. Do you have any plans of setting this up as a collaborative project? Can I help you by providing a place for you to do this? At the moment, I'm not able to provide much help for implementing any of the features listed in your thesis (although I am interested in working on and with this software at some point in the not-too-far future :)), but please let me know if I can help by providing resources, as this is something that I can do with little effort and in little time. Congratulations, and good luck with your study! Kind Regards, Devon H. O'Dell
