When used as a corporate security tool, it's important to keep in mind that a NPA needs to be distributed since this is going to make it possible for it to cover all of the network's areas. Choosing and implementing a network analyzer

However, when a packet sniffer is used for the right purpose it proves itself to be a perfect resource for your network. Software wifi packet sniffers are most commonly used for either the invasion of privacy or others for monitoring server traffic, where as hardware wifi packet sniffers are most commonly used for diagnostics and monitoring for performance and security related purposes. Hardware is used for packet sniffing typically works just like a router, where as software based wifi network analyzers run on the devices being monitored. Wifi network analyzers come in hardware, as well as software versions. What types of Wifi Network Analyzers are there? I found sourcecode for keyloggers via PS/2 but I could not find any similar project to capture USB.A network protocol analyzer is a combination of programming and hardware and in certain cases, a separate hardware device that can be installed in a network or computer in order to improve its security level against viruses and other types of malicious activities. So I suppose that they have also the capabality to just listen to the packets that go over the cable.īut I could not find any libraries for that purpose. Some of these microcontrollers support to act like USB host and client. It could also be a PCI card that is designed to capture USB signals together with an API that allows me to access the captured data.īut it would be perfect if this would be possible with a cheap USB capable hardware like any of the Arduino flavors or a Teensy and an open source library. It would not serve me to have a professional software that only shows me the captured packets on the screen.Ī comercial solution would be possible if costs less than $200.

And apart from that I need to process the captured data in my own code.

But I need a hardware solution that does the capture and sends the captured packets to another computer. I know that there are several software sniffers like Wireshark that can do that. I wanto to capture and then process the USB data that is sent from a computer to a USB printer.
