<\/a><\/p>\n6. The methodology :<\/p>\n
The Raspi will use Kali Linux ARM and will have 2 interfaces eth0 and wlan0. The ethernet interface will be the LAN and connected to the Client PC. Wireless interface wlan0 will be the WAN interface and connected to the local AP that provide the internet. Raspi will act as internet gateway and also the Wireless IDS. For the time being this WIDS only will detect de-authentication attacks. I’ll use airmon-ng to set wlan0 on monitor mode and to use scapy to detect de-authentication packet from the Wireless Network. Once it’s detect the attacks, GNTP will send the notice on the client as depicted :<\/p>\n
