They made completing this project much easier for me. I would also like to thank everyone at Sybex who helped with the creation of this book, including acquisitions editor Jeff Kellum, production editor Eric Charbonneau, copy editor Liz Welch, editorial assistant Connor O’Brien and editorial manager Pete Gaughan. I owe all these individuals a lot of thanks for their patience while working with me on this book and keeping things on track. Jim Compton is the Development Editor for this edition of the book. Many thanks go to Jim for his time and his work in helping with the fl ow, organiza- tion, and suggestions that allowed me to make this book an easier read. His knowledge and attention to detail were a huge help. Also, thanks to Tom Carpenter the proofread technical editor for this edition of the book. The Technical Editor for this edition of the book again is Bryan Harkins. I want to thank Bryan for his timely reviews, comments, and great suggestions that helped make this book a valuable reference source. His years of experience as a technical trainer, engineer, security specialist and author were a great contribution in creating a book I hope you will enjoy reading. I would again like to thank the thousands of students who have taken the time to attend the computer networking classes I was given the opportunity to teach. Educating, mentor- ing, and entertaining so many of these individuals gave me the inspiration and motivation to author this book and hopefully many more. Of course, this book would not exist if it were not for the people at CWNP. The CWNP team has realized the need for vendor-neutral wireless LAN training and certifi cation and has done a great job of building a brand over the years that is now known worldwide. Finally, a thank you to all the manufacturers, vendors, organizations, and individuals that provided the subject matter, allowing me the technology and tools needed to write this book.

    International Journal of Advanced Networking Applications (IJANA) ISSN No. : 0975-0290 137 Wireless Local Area Networks: Threats and Their Discovery Using WLANs Scanning Tools Ms. Rakhi Budhrani Bhavnagar, Gujarat, India. 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.

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.

Only when I fall do I get up again”. - Vincent van Gogh © Ekhator Stephen Aimuanmwosa, (BTH) Karlskrona January, 2010 Email: [email protected] ii Evaluating Kismet and NetStumbler as Network Security Tools & Solutions ABSTRACT Despite advancement in computer firewalls and intrusion detection systems, wired and wireless networks are experiencing increasing threat to data theft and violations through personal and corporate computers and networks. The ubiquitous WiFi technology which makes it possible for an intruder to scan for data in the air, the use of crypto-analytic software and brute force application to lay bare encrypted messages has not made computers security and networks security safe more so any much easier for network security administrators to handle. In fact the security problems and solution of information systems are becoming more and more complex and complicated as new exploit security tools like Kismet and Netsh (a NetStumbler alternative) are developed. This thesis work tried to look at the passive detection of wireless network capability of kismet and how it function and comparing it with the default windows network shell ability to also detect networks wirelessly and how vulnerable they make secured and non-secured wireless network.
