Hi,

Bro can cope with your requirements.  
You just need to write a policy script to handle that.  
You declare global variables to count connexion attemps to your servers.  
You should take a look at the policy script “signatures.bro”. There is an example  
to detect vertical and horizontal scans.

Hope it’s helpful.
