Re: Detect Network Sniffing

[Kenneth Walling <metajunkie () gmail com>]

While there is work being done with "quantum computing" that involves being able to measure extremely small 
fluctuations in voltage changes on a line - there is nothing that I know of that can guarantee you aren't being sniffed.

A sniffing device does not need an IP address.  In fact, one can physically cut the transmit wire on an ethernet line 
to ensure that a listening device has no way to respond to anything.  I have used this technique to physically secure 
IDS monitoring sensors.

All it takes to sniff, is to have a card in promiscuous mode - so that it simply grabs all traffic.

Securing Apache Web Server with thawte Digital Certificate
In this guide we examine the importance of Apache-SSL and who needs an SSL certificate.  We look at how SSL works, how 
it benefits your company and how your customers can tell if a site is secure. You will find out how to test, purchase, 
install and use a thawte Digital Certificate on your Apache web server. Throughout, best practices for set-up are 
highlighted to help you ensure efficient ongoing management of your encryption keys and digital certificates.
