Multidimensional data is data that exists and changes in more than one dimension, by time, or spatially, or both, sometimes dynamically. Think here of tracking hurricane data in order to project the storm´s path, for just one example. As spatial and other multidimensional data structures become increasingly important for the applications in game programming, data mining, bioinformatics, and many other areas--including astronomy, geographic information systems, physics, etc., the need for a comprehensive book on the subject is paramount. This book is truly a life´s work by the author who is clearly the best person for the job.
This book teaches test managers advanced skills in test estimation, test planning, test monitoring, and test control. Readers will learn how to define the overall testing goals and strategies for the systems being tested. This hands-on, exercise-rich book provides experience with planning, scheduling, and tracking these tasks. You´ll learn to describe and organize necessary activities, as well as to select, acquire, and assign adequate resources for testing tasks, and how to form, organize, and lead testing teams. You´ll master the organization of communication among team members and between the testing teams, and other stakeholders. Additionally, you´ll learn how to justify decisions and provide adequate reporting information where applicable.

Computer Software is an integral part of modern society. Companies rely on applications to manage client information, payment data, and inventory tracking. Consumers use software for a variety of different reasons as well--to manage their daily lives, to communicate with friends and family, and to browse resources made available on the internet, to name a few. With such a heavy reliance on software in our society, questions surrounding the security of the pieces of software performing these various tasks begin to arise. Is the software we are using really secure? How can we verify that it is? And what are the implications of a particular application being compromised? These are some of the questions that this book attempts to address. This book sheds light on the theory and practice of code auditing--how to rip apart an application and discover security vulnerabilities, whether they be simple or subtle, and how to assess the danger that each vulnerability represents. Product Description ´´There are a number of secure programming books on the market, but none that go as deep as this one. The depth and detail exceeds all books that I know about by an order of magnitude.´´ -Halvar Flake, CEO and head of research, SABRE Security GmbH The Definitive Insider´s Guide to Auditing Software Security This is one of the most detailed, sophisticated, and useful guides to software security auditing ever written. The authors are leading security consultants and researchers who have personally uncovered vulnerabilities in applications ranging from sendmail to Microsoft Exchange, Check Point VPN to Internet Explorer. Drawing on their extraordinary experience, they introduce a start-to-finish methodology for ´´ripping apart´´ applications to reveal even the most subtle and well-hidden security flaws. The Art of Software Security Assessment covers the full spectrum of software vulnerabilities in both UNIX/Linux and Windows environments. It demonstrates how to audit security in applications of all sizes and functions, including network and Web software. Moreover, it teaches using extensive examples of real code drawn from past flaws in many of the industry´s highest-profile applications . Coverage includes . Code auditing: theory, practice, proven methodologies, and secrets of the trade . Bridging the gap between secure software design and post-implementation review . Performing architectural assessment: design review, threat modeling, and operational review . Identifying vulnerabilities related to memory management, data types, and malformed data . UNIX/Linux assessment: privileges, files, and processes . Windows-specific issues, including objects and the filesystem . Auditing interprocess communication, synchronization, and state . Evaluating network software: IP stacks, firewalls, and common application protocols . Auditing Web applications and technologies This book is an unprecedented resource for everyone who must deliver secure software or assure the safety of existing software: consultants, security specialists, developers, QA staff, testers, and administrators alike.
