RE: Snort sensor on a Firewall

You can use the same machine as firewall and Snort and Snort will see all of
the traffic, provided you configure Snort to run on the public side network
interface. This is because Snort captures data before it reaches the
firewall packet filter. However it is not a good idea to combine IDS and
Firewall on the same machine.

Sireesha,

 

In short:

 

Placing Snort on the far side of the firewall will allow Snort to monitor
all traffic.

 

Placing Snort on the near side of the firewall will allow Snort to detect on
everything that gets past the firewall.

Subject: [Snort-users] Snort sensor on a Firewall

 

I am new to Snort. I am using snort for a class project.I have a doubt
regarding placement of snort sensor. 

 

Can I place a snort sensor on a firewall and monitor all the traffic coming
into internal network from the internet??? Will that be same as placing a
snort sensor on a different box outside the firewall?? In brief will the
snort on firewall be able to monitor all the packets before filtering
them???

 

Thanks.

Sireesha
