WiFi Security Protocols
In today’s world Wi-Fi has become the essential thing in our daily routine. The wireless networks are also not secure in this digital age. New flaws and exploits are found on daily basis and Wi-Fi is no exception in that. Let’s understand the functioning and the flaws present in it. Before diving deep into the protocols and standards, here is an overview of Wi-Fi. Wi-Fi (802.11) - an IEEE wireless communication standard has 14 channels. These channels ranges from 2.412GHz (Channel 1), 2.417GHz (Channel 2) to 2.484 GHz (Channel 14) and 6 modes- Master, Managed, Ad-Hoc, Mesh, Repeater and Monitor. As we all are familiar with the terminologies- Packets and Frames, let’s jump onto the main topic- Wi-Fi security Protocols and flaws in it. WEP, WPA, WPA2-AES WEP: Wired Equivalent Privacy is the security protocol which uses 64, 128 and 256 bit keys. 256 bit key is rarely used. Initialization Vector is used along with RC4 for
