Re: Snort with an expert system

So after the precious discussion, I have the following questions:

* Would the following setup be useful (interesting enough to be used)?
        (a) a set of sensors reporting "interesting" events from traffic 
and from hosts (e.g. from NIDS, HIDS, etc.), and then
        (b) we use an anomaly detector to detect unusual patterns in 
these events
        (c) (To make it completely useful, we must contextualize the 
alerts but that is kind of a next step).

* Would a third step be interesting?
       (d) asses the probability that the unusual pattern is an attack 
based on previous classifications

* Richard suggests that a IDS should have been called a "Attack 
Indication System" instead. However, to test such as system, we would 
not still need to be able to see how many real attacks it can detect, so 
it would still be tested as an IDS?
