This document discusses wireless network security protocols. It describes three main protocols: WPA, WPA2, and HTTPS. WPA and WPA2 were developed to improve on the original 802.11 security standard. They use encryption keys to secure the network. HTTPS is a protocol for secure communication over the internet that provides authentication and encrypted transmission of data. It ensures privacy and integrity of data transmitted between web servers and browsers.
