Programmable embedded system design: A study on sniffer

Abstract

Intrusion Detection Systems (IDS) are designed for capturing the attacks from internet or local area network consisting of various packets and data. Software or hardware IDSs detect the attack considering the network and user parameters. In order to determine the attacks, it is necassary to know some properties of the packets which convey data between networks. Capturing the packets between Networks and computers is called as sniffing. The MAC address, packet size, packet type and IP addresses of the captured packets are given to lDS an input. Thus , the first step is to capture the packet for designing the IDSs. It is very crucial to perform these procedures in real time and fastly. The implementation of real time lDS with a programmable embedded system is a very attactive topic. In this paper, the procedure of capturing the necassary packet and frame is presented to implement a real time lDS programmable embedded system. ©2009 IEEE.
