Abstract:
One way to remove a client from the network is by de-authentication. The components
of a wireless network, usually referred to as a Wi-Fi network, are an AP (Access Point)
and a client. The de-authentication procedure may be initiated by either the AP or the
client. To de-authenticate, a de-authentication frame is utilised. A de-authentication
frame is a management frame. There are altogether three basic frame types in the
IEEE 802.11 standard. Data frames that used to move information between stations.
There are various distinct types of data frames, depending on the network. Performing
area-clearing operations, channel acquisition and carrier-sensing maintenance tasks,
and positive acknowledging of received data all need the employment of control frames
in conjunction with data frames. The Management frames complete the process by
performing supervision duties; they are used to enter and exit wireless networks. Management frames like de-authentication and disassociation result in the termination of a
client’s network connection. The transmission of management frames has always been
done in clear text and without message authentication. Due to the fact that they are
delivered in clear, de-authentication or disassociation frames can be readily spoofed on
the part of a client or an AP. As a result, neither the client nor the AP will be in the
802.11 standard’s authenticated state. Following then, all packets will be discarded until
authentication is restored, which will result in the client’s network services being cut
off. This assault, a de-authentication attached, is comparable to the man-in-the-middle
assault. This specific weakness in the 802.11 Management Frames involves very careful
detection and mitigation of de-authentication attacks in Wi-Fi Networks. The goal of
this study is to discover a de-authentication attached while it is occurring or has just
begun.
