If a few of you can stop being so pedantic for a second, the definition looks pretty easy to me: traffic unlikely to be wanted by the recipient. Presumably, if it's being sent that means somebody wanted to send it, so the senders' desires are a pretty meaningless metric.
Thanks Steve - good point. I have to believe that some of those that have solutions to some of these problems have made *some* measures so they can quantify the value of their solution.
The harder pieces are going to be defining what traffic is unwanted in a way that scales to large-scale measurement. Worm traffic is presumably measurable with Netflow, as are various protocol-types used mainly in DOS attacks. Spam is harder to pinpoint by watching raw traffic, but perhaps comparing the total volume of TCP/25 traffic to the SpamAssassain hit rates at some representative sample of mail servers could provide some reasonable numbers there.
Yea, we can't get absolute #'s, but I think it would be helpful to have a defensible approximation.
So, any of you security types have a list of the protocols that are more likely to be attack traffic than legitimate?
Or maybe those in the Research Community that have been doing traffic capture and analysis?
