WPA: Naturally, a safer wireless security standard had to replace WEP, and, in 2003, WPA (Wi-Fi Protected Access) became that standard.It’s safe to say that even children can learn how to hack into a WiFi protected by WEP with minimal effort.

The exploit makes it possible to hack virtually any WEP network within a few minutes using readily available software programs and standard networking equipment. In 2001, a group of security researchers published a method on how to exploit the way the RC4 cipher is used in WEP. It uses the stream cipher RC4 for confidentiality and the CRC-32 checksum for integrity.

The most common wireless security standards are:

WiFi networks rely on several common wireless security standards to prevent unauthorized access.
