Are there any machine learning functionality in Bro?

Dear Bro maillist members,

I am doing a school project on Bro capabilities.

I still have not found any “machine learning” functionality.

The most interesting so far is;

Radix or Patricia Tree algorithm

The Smith-Waterman algorithm and

Threshold Random Walk algorithm (TRW).

Are the learning capabilities in Bro well hidden – or missing?

I really appreciate any feedback on this question !

Thanks,

(TRW doesn't use machine learning.)

Missing. Not by design, but out of operational concerns: it's
extremely hard to get ML approaches to work reliably. You may be
interested in this paper we wrote a little while ago on this topic:

You know a project is awesome when a response indicating that a
feature isn't available is accompanied by a full paper on it.
