Greetings Everyone,
Is there such a thing as sniffer detection software? And if so what would be a good choice for a MAC running OS X? I would like to monitor my home computer for sniffing activity. And since my computer is already running in "stealth mode" as well as denying "UDP" traffic would I just be wasting my money?
Thanks!

There are Intrusion Detection Systems that can detect some types of sniffing, but if it’s your home office, then it won’t do any good (unless you have many computers inside your home with a few untrusted (which would be unique
.
So, it would be wasting your time from what I can see.
By the way, an IDS doesn’t have to cost you a cent and a great one is SNORT – I am not sure of IDS software for the MAC.
Best regards,
Jim.
