Project Title: Managerable 10/100 Mbps Ethernet Tap Device Abstract: The need for listen-only Ethernet stems from the practices of ``packet sniffing, or passivley recording all the data-traffic passing through a specific point on a network. Most good network administrators do some form of packet sniffing regularly for the multiple purposes, such as intrusion detection, traffic analysis, password auditing and bandwidth analysis. All these activities provide the administrator with a wealth of useful information, however should a computer containing such information be compromised by an attacker, this same information will be invaluable to that attacker's effort to further intrude on the network. The most common solution to this problem is to deply these monitoring systems in listen-only mode: they have the ability to remotely capture traffic, but cannot send traffic of their own. Due to the nature of software, it will always be vulnerable, in one way or another to attacks or configuration problems. Since hardware is much more difficult to affect over the internet/network, this project will turn a computers two-way connnection to a network into a recieve only connection using hardware.
