Analysis of attack and protection systems in Wi-Fi wireless networks under the Linux operating system

This article describes the preparation of a Wi-Fi wireless network in production system, with intrusion detection systems Snort and Kismet; for subsequent evaluation under attack. Through Penetration Testing with Backtrack 5 R3 using Fern WiFi Cracker and Ettercap to monitor response reaction of IDSs. Once the attacks are completed, the results are analyzed, in terms of the captured traffic by the system using Wireshark, and the attack description, in order to determine the response characteristics of Snort and Kismet. In addition, minimum safety recommendations are deducted, targeting both network administrators and clients; to avoid problems with the attackers.
