SECURING WIRELESS NETWORK

INTRODUCTION

In todays world of speed, mobility and reliability numerousorganizations have deployed wireless networks for better

efficiency of the work contrary to wired network.

Wireless security is the quality of data processing concerningthe prevention of unauthorized access or damage to function ofand data with computers via wireless networks.

Wireless network has become very popular in the home andoffice networks.

Wireless networks serve as the transport mechanism between

devices and among devices and the traditional wired networks.

Wireless networks are many and diverse but are frequently

categorized into three groups based on their coverage range:

Wireless Wide Area Networks (WWAN), WLANs, and WirelessPersonal Area Networks (WPAN).WWAN includes wide

coverage area technologies such as 2G cellular, Cellular Digital

Packet Data (CDPD), Global System for Mobile

Communications (GSM), and Mobitex. WLAN, representingwireless local area networks, includes 802.11, Hiper LAN, and

several others.

NEED OF SECURITY

The advantages of wireless are tremendous, the security issues

are real. Now we need to implement security measures for

protecting sensitive data within the wireless network area,reducing unnecessary bandwidth consumption and proving the

liability and account ability of the network.

Wireless users need to protect their networks with the tools thatcan provide the same level of security as wired networks.

COCLUSIONSAs wireless networks are becoming integral part of

organizations, industries, enterprises, homes and other

businesses, security becomes the major concern for wireless

network deployment. Hence Countermeasures to provide thesecurity are utmost important. By implementing and using

software and hardware countermeasures, organizations can

mitigate maximum amount of risks and should be shield from

unauthenticated attacks.
