[Snort-users] Question about Artificial Neural Networks, Preprocessors and Snort

Hello Russ, thank you for replying!

I've heard of Snort++ and you're the second to recommend it for someone who wants to develop custom preprocessors, so I'm definitely looking for it.
I'm not sure how I would feed my ANN, but I'm probably using a known dataset, for example, the KDD Cup 1999 Data, so I'm assuming they are raw packets? (Feel free to correct me).

Any other thing I should look up to if I'm going to write a Preprocessor?
I've been reading a lot of articles about people who integrated IA into Snort through modules, plug-ins, but it's hard to find a good source that can be used as a "tutorial".

I found a paper from SANS Institute called "Developing a Snort Dynamic Preprocessor", but now that you suggested Snort++, I have no idea on how different things are going to be now.

Again, thanks!

First recommendation is to use Snort++.  You will have an easier time
getting something running and it will be easier to tweak if necessary to
support your needs.  This is a wide open question, so it would help to
know what kind of data you want to feed your ANN (raw packets or PDUs,
etc.).

At the moment, considering I'm a complete newbie w/ Snort, the methodology would consist of developing a Snort Preprocessor, with a ANN implemented in it.
