Quoting Marcus Schopen <[EMAIL PROTECTED]>:

Hi,

on my DSL-router (masqurading) at home I'd like to install snort to see who attacks me from the internet side. I know that one should install snort on a seperate hosts before and behind the firewall to get the best results, but this is just my little "home net" and I don't want to set up further linuxboxes.

So my question: what are the risks to set up snort on the gateway-router instead of using a seperate snort host? Is that insecure? And why?



Marcus,
  Snort is a program just like any other that listens to a network
connection, it can be compromised.  AFAIK, the worst that has happened
recently is that a flaw allowed an attacker to disable Snort.  I
consider running Snort to be better than not running it.  For another
possible approach, see an article I wrote:

http://www.linuxjournal.com/article.php?sid=6985

The article is great but does not help in my case, because I use pppoe to connect to my provider.


Bye,
Marcus
