As we all know, wireless networks are spread at each and every part
of the world, starting from personal home to corporate business
environments, schools/universities, cafes, etc. The major merit of
wireless networking is to eliminate the big and untidy cables, which
acquires space and unspoils the look of your working area. But as we all
know, each coin has two sides. There are demerits of wireless
networking as well. It comes with high possibility of attacks on it. In
this article I am going to describe different techniques of attacks on
wireless networks and what we should do to prevent them.
Lets start with WLAN protocol, which is also known as 802.11
protocol, commonly used for wireless networking. The major function of
this protocol is to link more than one device. It uses spread spectrum
signals. The functionality of these signals is based on radio frequency
communication where networking is established between two point-to-point
end devices consisting of a transmitter and a receiver. In this
mechanism, participants (in terms of end devices) must have transmitters
and receivers to send and receive signals.
To connect to the wireless network, each participant must have
wireless AP (Access Point also known as Wi-Fi hot-spot) along with the
wireless adaptor. The AP acts as a walkie-talkie. It converts radio
signals into digital signal and vice-versa. When AP transmit the
signals, those signals have SSID, known as service set identifier &
information of network identification. The receiver detects the signals
and lists the available wireless network around him/her, along with the
signal strength. Not only this, it also identifies whether the AP is
using any security, and if yes, then what is the level of security. As
its wireless network, it allows more than one node to let those nodes
connect with the network, so that is why authentication is important to
ensure there is not any malicious Internet user lying in that network.
The AP holds this responsibility.
