how to block MSN Sniffer

Postby mudasir » Thu Aug 23, 2007 7:14 am

AOA,

I have a question, in my network one of my users is using MSN Sniffer, monitoring all the MSN conversations, i know the IP Address of the person doing this.
I want to know is there any way to stop that guy from doing that wothout him knowing anything or do anything that will stop any sniffing applications.

I am using simple MAC Address Based Authentication through IPTABLES and using Squid as a Proxy and caching server.

Looking Forward for some help.

well, first take a look at Sniffers: Basics and Detection
for better understanding.

The packets of MSN Messenger are sent over the network in cleartext form which make it highly insecure, its better to use some encrypting application to secure chat packets i.e.

Its extremely difficult to detect sniffers, however see some useful links for Sniffer Detection.
