Hi,

I had a general question regarding Bro.  
Can we classify it under Rule based or Anomaly based as usually IDSs are  
classified ?  
I would guess it is a Rule based one. Is there any anomaly detection in  
Bro ?

When it is stated that an IDS can withstand upto or greater than 'X'  
Mbps,  
do we make any assumptions regarding the number of rules in the  
rule-based IDS ?  
I would think as the rules increases, the traffic that the IDS can  
withstand should decrease.

thanks a lot  
Ashley
