Bachelor Thesis from the year 2006 in the subject Computer Science - IT-Security, grade: 1.7, University of Wales, Newport, (North East Wales Institute of Higher Education), language: English, abstract: This paper addresses the theory and reality of Wi-Fi security. It provides an overview of security mechanisms and explains how security works in wireless networks. The most important security protocols that are relevant for small office or home office environments are looked upon in more detail. The security of a real-world wireless network is being tested with freely available tools and popular attacking methods. It is demonstrated that old security protocols can no longer be seen as being secure at all. To create a holistic view the idea of Wi-Fi security is then expanded to include the physical level. A series of experiments provides insight on how to make a network more secure with materials and tools available in every household. A WLAN that is nearly unreachable outside the perimeter does not attract any potential hackers. The paper concludes with recommendations on where to place your access point and what can be done to shield it.

The real-world guide to securing Cisco-based IP telephony applications, devices, and networks Cisco IP telephony leverages converged networks to dramatically reduce TCO and improve ROI. However, its critical importance to business communications and deep integration with enterprise IP networks make it susceptible to attacks that legacy telecom systems did not face. Now, there’s a comprehensive guide to securing the IP telephony components that ride atop data network infrastructures–and thereby providing IP telephony services that are safer, more resilient, more stable, and more scalable. Securing Cisco IP Telephony Networks provides comprehensive, up-to-date details for securing Cisco IP telephony equipment, underlying infrastructure, and telephony applications. Drawing on ten years of experience, senior network consultant Akhil Behl offers a complete security framework for use in any Cisco IP telephony environment. You’ll find best practices and detailed configuration examples for securing Cisco Unified Communications Manager (CUCM), Cisco Unity/Unity Connection, Cisco Unified Presence, Cisco Voice Gateways, Cisco IP Telephony Endpoints, and many other Cisco IP Telephony applications. The book showcases easy-to-follow Cisco IP Telephony applications and network security-centric examples in every chapter. This guide is invaluable to every technical professional and IT decision-maker concerned with securing Cisco IP telephony networks, including network engineers, administrators, architects, managers, security analysts, IT directors, and consultants. Recognize vulnerabilities caused by IP network integration, as well as VoIP’s unique security requirements Discover how hackers target IP telephony networks and proactively protect against each facet of their attacks Implement a flexible, proven methodology for end-to-end Cisco IP Telephony security Use a layered (defense-in-depth) approach that builds on underlying network security design Secure CUCM, Cisco Unity/Unity Connection, CUPS, CUCM Express, and Cisco Unity Express platforms against internal and external threats Establish physical security, Layer 2 and Layer 3 security, and Cisco ASA-based perimeter security Complete coverage of Cisco IP Telephony encryption and authentication fundamentals Configure Cisco IOS Voice Gateways to help prevent toll fraud and deter attacks Secure Cisco Voice Gatekeepers and Cisco Unified Border Element (CUBE) against rogue endpoints and other attack vectors Secure Cisco IP telephony endpoints–Cisco Unified IP Phones (wired, wireless, and soft phone) from malicious insiders and external threats This IP communications book is part of the Cisco Press® Networking Technology Series. IP communications titles from Cisco Press help networking professionals understand voice and IP telephony technologies, plan and design converged networks, and implement network solutions for increased productivity.

Business is on the move - mobile computing must keep up! Innovative technology is making the communication between computers a cordless affair. Mobile computing with laptops, hand helds and mobile phones is increasing the demand for reliable and secure wireless networks. Network engineers and consultants need to create and build cutting-edge wireless networks in both the small business and multi-million dollar corporations. Designing Wireless Networks provides the necessary information on how to design and implement a wireless network. Beginning with detailed descriptions of the various implementations and architectures of wireless technologies and moving to the step-by-step instructions on how to install and deploy a fixed wireless network; this book will teach users with no previous wireless networking experience how to design and build their own wireless network based on the best practices of the Enhanced Services from Lucent Technologies. * Timely coverage of new technologies: Communication without cables is the future of netwoking * Advocates wireless networking solutions for any user, regardless of location, device or connection. * Written by Experts. The authors are leading WAN authorities at Lucent Technologies. * No previous wireless experience is assumed, however, readers should have a basic understanding of networking and TCP/IP protocols

In a constant stream of new ideas, wireless technologies continue to emerge offering a range of capabilities, each affording simplicity and ease-of-use. Such diversity and choice should surely beg the question, "are manufacturers using the right technology for the right product? Developing Practical Wireless Applications will explore this question and, in doing so, will illustrate many of the wireless technologies currently available whilst drawing upon their individual strengths and weaknesses. More specifically, the book will draw your attention to the diverse collection of standardized and proprietary solutions available to manufacturers. As developers and innovators your choices are not restricted to any norm and, as such, a standardized or proprietary solution may afford you greater benefits in realising any product roadmap. Developing Practical Wireless Applications will provide you with a comprehensive understanding of how each technology works, coupled with an exploration into overlapping, complementary and competing technologies. In establishing this foundation, we will explore wireless applications in their context and address their suitability. In contrast, the book also considers the practicality of a wireless world in an attempt to better understand our audience and specific demographic groups. Coupled with a richer understanding of our consumers, along with our technology make-up we can indeed target wireless products more effectively.*Explores techniques used to attack wireless networks including WarXing, WarChalking, BlueJacking, and BlueSnarfing*Discusses applications utilizing ZigBee, NFC, RFID, Ultra-Wideband and WirelessUSB (WiMedia)*Details Bluetooth 2.x +EDR and introduces the v3.0 (BToverUWB) specification *Includes fundamental introductions to WiFi, namely 802.11i, 802.11p and 802.11n*Compares personal-area and wide-area communications including 3G, HSDPA, 4G, and WiMAX, as well as introducing Wireless Convergence
