Hi,

 

I actually want to place snort sensor on the same machine as firewall. My
firewall has two interfaces one of which is connected to internet and other
to the internal network. If I place two snort sensors one on each of those
interfaces will that work same as snort sensors before and after the
firewall (before and after in the sense on separate linux boxes)

 

Thanks.

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.

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
