NetworkMiner is a free network analysis tool that runs under Windows.
NetworkMiner is a Network Forensic Analysis Tool (NFAT) for Windows. NetworkMiner can be used as a passive network sniffer/packet capturing tool in order to detect operating systems, sessions, hostnames, open ports etc. without putting any traffic on the network. NetworkMiner can also parse PCAP files for off-line analysis and to regenerate/reassemble transmitted files and certificates from PCAP files.
The purpose of NetworkMiner is to collect data (such as forensic evidence) about hosts on the network rather than to collect data regarding the traffic on the network. The main view is host centric (information grouped per host) rather than packet centric (information showed as a list of packets/frames).
NetworkMiner can run from a USB thumb drive, and there’s also a 500 Euro professional edition.
