- [Instructor] I'll use a tool called Network Miner…on a Windows system to demonstrate…passive network discovery.…This tool is free to download,…easy to use, and very effective…at passively detecting devices on the network.…To get started,…I'll open Network Miner as administrator…and select a network adapter.…Then, I'll click start.…Network Miner is now using it's network adapter…to listen for any network activity.…Since this demo network only has a few systems on it,…most of them will appear within a minute or two.…
I'll let the capture run for five minutes.…Now I'll stop the capture.…The address range of our network is 10 zero two zero…through 10 zero two 255,…so only devices with addresses…in that range are interesting to us…for the purpose of network discovery.…Looking at addresses in that range…discovered by the Network Miner software,…we see that several devices have been discovered.…Network Miner has also been able to discover…some basic information about the systems on the network,…such as the fact that we have…
