A Packet Sniffer (PSniffer) Application for Network Security in Java

This paper presents the full implementation of the Psniffer application software that captures network data as well as provides sufficient means for the decision making process of an administrator. The aim of this application is to rewrite C language sniffer into Java, and also develop an application that consumes little memory on the hard disk. This work illustrates the requirement needed to design a new application; it was developed in Java and it consumes little memory on the hard disk. This application comprises of five independent modules that handles different tasks efficiently. This program can monitor network traffic, analyzes traffic patterns, identify and troubleshoot network problems. This application does not transmit any data onto the network, uses 1MB of the hard disk space, friendly GUI and it is very easy to install. Keywords: network traffic, packets, packet capture, packet analyzer/sniffer.
