Book Description
Security mechanisms like encryption negatively affect other software quality characteristics like efficiency. To cope with such trade-offs, it is preferable to build approaches that allow to tune the trade-offs after the implementation and design phase. This book introduces a methodology that can be used to build such tunable approaches. The book shows how the proposed methodology can be applied in the domains of database outsourcing, identity management, and credential management.

Book Description
Master the basics of data centers to build server farms that enhance your Web site performance Learn design guidelines that show how to deploy server farms in highly available and scalable environments Plan site performance capacity with discussions of server farm architectures and their real-life applications to determine your system needs Today's market demands that businesses have an Internet presence through which they can perform e-commerce and customer support, and establish a presence that can attract and increase their customer base. Underestimated hit ratios, compromised credit card records, perceived slow Web site access, or the infamous "Object Not Found" alerts make the difference between a successful online presence and one that is bound to fail. These challenges can be solved in part with the use of data center technology. Data centers switch traffic based on information at the Network, Transport, or Application layers. Content switches perform the "best server" selection process to direct users' requests for a specific service to a server in a server farm. The best server selection process takes into account both server load and availability, and the existence and consistency of the requested content. Data Center Fundamentals helps you understand the basic concepts behind the design and scaling of server farms using data center and content switching technologies. It addresses the principles and concepts needed to take on the most common challenges encountered during planning, implementing, and managing Internet and intranet IP-based server farms. An in-depth analysis of the data center technology with real-life scenarios make Data Center Fundamentals an ideal reference for understanding, planning, and designing Web hosting and e-commerce environments.

Book Description
The cell phone is the fastest-selling consumer electronic in the world. On a global basis, over 800 million cellular telephones are sold yearly. More camera-equipped cell phones are sold each year than stand alone digital cameras. Rapid development of new technologies is leading to ever more versatile, multipurpose mobile devices, including 3G Internet-enabled cell phones and PDAs. Meanwhile, wireless networking and wireless Internet access are developing and expanding on a global basis at a rapid rate. Booming technologies include such 802.11 standards as Wi-Fi and WiMax, as well as Ultra Wide Band (UWB) and Bluetooth. Telematics, intelligent transportation systems (ITS) and satellite radio will soon create an entertainment, navigation and communications revolution within automobiles and trucks. Meanwhile, RFID (radio frequency identification) will revolutionize wireless tracking, inventory and logistics at all levels, from manufacturing to shipping to retailing. These developments are creating challenges for legacy companies and opportunities for nimble marketers and managers. Plunkett's Wireless, Wi-Fi, RFID & Cellular Industry Almanac 2007 covers such sectors. Our coverage includes business trends analysis and industry statistics. We also include a wireless and cellular business glossary and a listing of industry contacts, such as industry associations and government agencies. Next, we profile hundreds of leading companies. Our company profiles, nearly 350, include complete business descriptions and up to 27 executives by name and title.

Book Description
At its core, information security deals with the secure and accurate transfer of information. While information security has long been important, it was, perhaps, brought more clearly into mainstream focus with the so-called “Y2K” issue. Te Y2K scare was the fear that c- puter networks and the systems that are controlled or operated by sofware would fail with the turn of the millennium, since their clocks could lose synchronization by not recognizing a number (instruction) with three zeros. A positive outcome of this scare was the creation of several Computer Emergency Response Teams (CERTs) around the world that now work - operatively to exchange expertise and information, and to coordinate in case major problems should arise in the modern IT environment. Te terrorist attacks of 11 September 2001 raised security concerns to a new level. Te - ternational community responded on at least two fronts; one front being the transfer of reliable information via secure networks and the other being the collection of information about - tential terrorists. As a sign of this new emphasis on security, since 2001, all major academic publishers have started technical journals focused on security, and every major communi- tions conference (for example, Globecom and ICC) has organized workshops and sessions on security issues. In addition, the IEEE has created a technical committee on Communication and Information Security. Te ?rst editor was intimately involved with security for the Athens Olympic Games of 2004.
