WEP(Wired Equivalent Privacy) is a Wi-Fi security protocol, its intention was to provide data confidentiality comparable to that of a traditional wired network. This mode enables packets to be captured without having to connect or link with an access point. Monitor mode allows the adapter to view and monitor all the traffic received from the wireless network. The reason we have to use an external adapter is that the inbuilt adapter that comes along with the PC doesn’t support monitor mode and packet injection. The first thing that we need to have to successfully attack, audit a network is a Wi-Fi adapter that has monitor mode and allows packet injection. The attacks are to be performed by obtaining the consent of the owner or only on those networks that are owned by you. The attacks range from Wifi Disconnection to obtaining handshakes to cracking passwords. It can be installed by using the following command on the terminal: sudo apt-get install aircrack-ng Aircrack-ng is used by learning individuals and security professionals to test the security, reliability of wireless networks. It is also used for cracking the WEP and WPA/WPA2-PSK keys for gaining access to a network.
Aircrack-ng is a Wi-Fi security auditing tool specifically 802.11 WEP and WPA/WPA2-PSK.
