Timeline of Wi-Fi
Wi-Fi was initially created for public use and security was never an idea thought to be implemented into the system. Introduced as part of the original 802.11 standard ratified in September 1999, WEP (Wired Equivalent Privacy) came out and was a black-box security system where its source code was not even released to the public.It was thought in the olden days that this first implementation of wireless security was secure enough to prevent people from eavesdropping people data in the air. This encryption was then used for encrypting business and home users data unknowingly that actually the security settings of WEP is very low.
