There use to be a Port Scan Detection (psd) match extension that would 
help detecting this easier.  I.e. did it look like a system was 
initiating a port scan, and if so, handle it accordingly (drop / reject 
/ tar pit / etc.).  I don't know what the current state of the psd match 
is, so you will have to find out.
