Nowadays, Computer Networks tend to be large and diverse systems that communicate using wide selection of protocols. This complexity made the desire for more sophisticated tools to watch and troubleshoot network traffic. Network traffic monitoring is can be quite a network diagnostic tool that monitors local area networks and provides a graphical display of network statistics. While collecting information through the network's data stream, network monitor displays the source address of the computer that sent a frame onto the network, the destination address of the computer that received the frame and also the protocols employed to send the frame. The procedure through which network monitor collects this information is known as Capturing. Automatically, the network monitor gathers statistics on all of the frames it detects on the network into a capture buffer that is a reserved storage area in memory. To capture statistics on merely a specific subset of frames, we could discriminate these frames by designing a capture filter. To work with network monitor, the computer will need to have a network card that supports promiscuous mode. This paper targets on the usage of packet capturing library Jpcap for monitoring, analyzing and reporting Distributed Denial of Service (DDoS) Attacks.
