Network Security : WiFi Security fixation

This signal contains the network identification; the service set identifier (SSID),and some trivial error correction information. The node such as a laptop or any wireless device, detects this signal in order to show it in the list of available wireless networks. It also detects whether or not the access point is using any security, and what level of security protocol etc. The access point contains TCPIP stack which responds to ARP requests when a node tries to connect to it. Since wireless can allow multiple nodes at any instance, it is essential to have an authentication layer prior to letting the data transfer take place. 2019 WiFi & Wireless Network Security Issues Explained.
