Securing wireless Networks

Now days wireless security have same importance as physical security because most of the devices by which we communicate are connected to wireless networks. So let us explore what is wireless, how devices connected to them and how we can secure them. In not only office, home but everywhere we can see the role of wireless and its importance in life of human.

What is Wireless network ?

In Wireless, network data travels over air with the help of electromagnetic radio waves and it also a type of “unguided media” as the signal gets propagated in the air without any guidance. We can see the example of wireless network in our homes where we use Wi-Fi. Now days wireless devices only have vertical rod type antenna that help to send and receive signal. Configuration can be done in 2-way:

· Ad-hoc/Independent basic service set: In this type of adapter connections can be established to or from the adapter

· Infrastructure/Basic service set: In this, we need access point i.e. through which adapter is connected to other devices and the MAC address of AP used as BSSID (Basic service set identifier). In ESS, we can group more than one BSS.

In LAN, AP is connected through cables by which it can transmit signal or traffic to the attached devices.
