Re: [Snort-users] Can snort be used for single host Intrusion Detection?(A newbie Question)

Okay, thanks, I see what you mean. I tried that too
but still manage to pick up attack traffic to another
host. Here is the scenario:

Suppose the host that has snort installed is
192.168.1.10, and i set my HOME_NET to
192.168.1.10/32.

Then i tried to use another machine 192.168.1.20 to
nmap another machine 192.168.1.30, the snort on
192.168.1.10 still can pick up the traffic and
generate alerts.

I understand that snort is more of a Netword based
IDS, but lets assume that i'm in a sad case where I
can't even trust my neighbours in the same network.
what other configuration needs to be done?
