ABSTRACT
Wardriving is
searching for Wi-Fi wireless networks by moving vehicle. It involves using a
car or truck and a Wi-Fi-equipped computer, such as a laptop or a PDA, to
detect the networks. It was also known as 'WiLDing' (Wireless Lan Driving).Many
wardrivers use GPS devices to measure the location of the network find and log
it on a website. For better range, antennas are built or bought, and vary from
omni directional to highly directional. Software for wardriving is freely
available on the Internet, notably, NetStumbler for Windows, Kismet for Linux,
and KisMac for Macintosh. Wardriving was named after wardialing because it also
involves searching for computer systems with software that would use a phone
modem to dial numbers sequentially and see which ones were connected to a fax
machine or computer, or similar device.
INTRODUCTION
Wardriving is
searching for Wi-Fi wireless networks by moving vehicle. Wardriving was first
developed by Pete Shipley in April 2001. It involves using a car or truck and a
Wi-Fiequipped computer, such as a laptop or a PDA, to detect the networks. Many
wardrivers use GPS devices to measure the location of the network find and log
it on a website. For better range, antennas are built or bought, and vary from
omnidirectional to highly directional. Software for wardriving is freely
available on the Internet, notably, NetStumbler for Windows, Kismet for Linux,
and KisMac for Macintosh. The gathering of statistics about wireless networks
in a given area by listening for their publicly available broadcast beacons is
War Driving. Wireless access points (APs) announce their presence at set
intervals (usually every 100 milliseconds) by roadcasting a packet containing
their service set identifier (SSID; basically, the user-defined name of the
access point) and several other data items. A stumbling utility running on a
portable computer of some sort (a laptop or PDA) listens for these broadcasts
and records the data that the AP makes publicly available. Wireless networks
have become a way of life in the past two years. As more wireless networks are
deployed, the need to secure them increases. The activity of driving around
discovering wireless access points is called WarDriving. In order to
successfully WarDrive, there are some tools, both hardware and software.
WarDriving is a fun hobby that has the potential to make a difference in the
overall security posture of wireless networking.
