Almost every electronic device is connected to the internet today. We have different mechanisms of connecting the devices for feasible communication that maybe wired or wireless. Also, wirelesses LANs are most popular and frequently used because of their cost effectiveness, easy deployment and configuration. A lot of data is being generated and transferred every day, which includes sensitive information. Network security consists of various policies and practices which prevent and monitor proper safeguard of network systems against misuse, unauthorized access of the information. Though different security techniques are implemented to protect this kind of information, but the threat of hackers is always lurking there, to intercept or intrude the security by finding loopholes in the wireless communication. This paper focuses on the existing wireless security protocols such as Wired Equivalent Piracy(WEP), Wi-Fi Protected Access(WPA), Wi-Fi Protected Access 2(WPA2) and their security issues.
