[ Team LiB ] [ Team LiB ] Acknowledgments I'd like to thank my family and friends for their continuing support in giving me the encouragement (and occasionally, solitude) needed to complete my various little projects. Many hacks in this book were inspired by conversations with countless hackers who willingly share their ideas with anyone who will listen. A few came from the weekly "hack night" sessions that SeattleWireless hosts to foster such cross-pollination of ideas. Without the free and enthusiastic exchange of ideas, this book wouldn't have been possible. Thank You to all of the brilliant hackers around the planet who know that the value of sharing one's ideas can greatly exceed the value of a keeping an idea to oneself. Edd Dumbill, Casey Halverson, and Richard Lotz all provided technical review for the book.

Dr. R. Sridaran, Dean, Faculty of Computer Applications, Marwadi Education Foundation’s Group of Institutions, Rajkot, Gujarat, India. ----------------------------------------------------------------------ABSTRACT-------------------------------------------------------- Wireless Local Area Networks frequently referred to as WLANs or Wi-Fi networks are all the passion in recent times. Wireless networks offer handiness, mobility, and can even be less expensive to put into practice than wired networks in many cases. But how far this technology is going provide a protected environment in terms of privacy is again an anonymous issue. Realizing the miscellaneous threats and vulnerabilities associated with 802.11-based wireless networks and ethically hacking them to make them more secure is what this paper is all about. On this segment, we'll seize a look at common threats, vulnerabilities related with wireless networks. This paper presents an overview some of the WLANs Scanning, Sniffing and Auditing tools available on the internet. This paper Reviews these tools along with their merits, demerits and how they can be used for hacking, exploiting security holes and their usage characterization in WLANs. Keywords - Current threats in WLANs, Exploiting Security, WLANs Scanning, WLANs Sniffing, Multifunctional, WLANs auditing tools penetrate any wired network via wireless network as Access Point (AP) is bridging between wireless and I. INTRODUCTION wired network. Wireless Networks present a host of issues for network managers.

NetStumbler http://www.stumbler.net/ 5 NetStumbler was one of the first and most widely used WiFi detection tools. It runs only in Windows XP or Windows 2000, and works with many (but not all) wireless cards. NetStumbler can be used for mapping the coverage of your WiFi network, War Driving, rogue AP detection, aligning antennas on a long distance link, and more. NetStumbler is not open source, and was last updated in 2004. http://www.vistumbler.net/ 6 Vistumbler is an updated open source network detection tool for Windows Vista and Windows 7. It supports many of the same features as NetStumbler, including network detection and GPS integration. It also works with Google Earth to allow realtime WiFi mapping on a live map.

  • Wireless Networks Security in Jordan: a Field Study
    International Journal of Network Security & Its Applications (IJNSA), Vol.5, No.4, July 2013 Wireless Networks Security in Jordan: A Field Study Ahmad S. Mashhour1&Zakaria Saleh2 1IS Dept, University of Bahrain [email protected] 2MIS Dept, Yarmouk University, Jordan [email protected] ABSTRACT The potential of wireless communications, has resulted in a wide expand of wireless networks. However, the vulnerabilities and threats that wireless networks are subjectedto resulted in higher risk for unauthorized users to access the computer networks.This research evaluates the deployed Wireless Network in Jordan as well as the use of the security setting of the systems and equipment used. Caution will be taken to avoid network access as only existence of the network is sought. Wardriving involve the use of freeware tools such as NetStumbler, or Kismet, which was originally developed to be used for helping network administrators make their systems more secure. Thestudy is carried out through field evaluation of the Wireless Local Area Network (WLAN)in light of the use of Wardriving, and proposessome measures that can be taken to improve securityof the wireless network by the users. KEY WORDS Security, Wardriving, Wireless Local Area Network (WLAN), Wired Equivalent Privacy (WEP). 1. INTRODUCTION Wireless networks have evolved rapidly in the last few years due to the developments of new wireless standards and cost-effective wireless hardware. This has led to widespread adoption of the technology in home and small businesses. With the growth of wireless networking, security is the main weakness of the whole wireless system, which resulted in improper uses of network resources.
