Wireless Security: Latest Issues and Security Measures

This paper is based on wireless fidelity that is "Wi-Fi" an 802.11 IEEE standard. The main issue in Wi-Fi system is the security issue. In this paper, the various security hazards are discussed and the measures to overcome those are also explained. There are various mechanisms that can be used for the wireless security e.g. MAC address filtering will prevent casual users from connecting to the network by maintaining a list of MAC addresses that are allowed access, (or not) but a serious cracker will simply scan the network traffic to find a MAC address that is allowed access, then change their equipment to use that address.
