Perhaps I am the one who is missing something. I do not know snortsam (I
will try it for sure). I thought that a white-list is the list of ip
addresses that snortsam will not block and 'analyze' as snort does when
you put the DNS ip address to avoid false positive. However I am would
like to understand how snortsam can manage a syn flood attack where the
ip source is randomly generate for each packet sent. (e.g. synk4).
Filling up the logs, and blocking hundreds o thousand of random ip
address would not be consider a successful DoS?
