RE: Detect Network Sniffing

  ARP poisoning can be part of the mix when someone *without infrastructure
admin access* tries to sniff traffic on a switched network.  ARP poisoning
isn't needed by a sniffer who has admin access to the infrastructure, or on
a shared-media network.

  If, as an admin, you want to protect your users from sniffing by
intruders, then ARP poisoning is one of the things you should watch for.

Is there any way to detect if a sniffer is being used to analyze my
traffic before it gets onto the Internet? Also is it required for a
sniffer to have an IP address or can it sniff while remaining
"uncontactable" on the network?

Hello,

if the sniffing is done through arp poisoning, you can install arpwatch.
A daemon for monitoring Address Resolution Protocol traffic anomalies and
sending email alerts.
