Its goal is to provide views, graphs, metrics, and more to help extract useful information from traces, in a way that is more user-friendly and informative than huge text dumps. It accepts as input a capture file (. You might want to take a look at tcprewrite, bittwiste, pktanon and other tools. Network analysis also can lend to protocol analysis and the ability to improve anomaly and IDS signature detection, when the analysis team has visibility to the system and the network for trace events that occur at nearly the same time. In this section, we consider the characteristics of traffic flow information. bro -r trace. tcpdump is without question the premier network analysis tool because it provides both power and simplicity in one interface.
