    Instead of relying on another attacker's tools, this book will teach you to forge your own weapons using the Python programming language. This book demonstrates how to write Python scripts to automate large-scale network attacks, extract metadata, and investigate forensic artifacts. It also shows how to write code to intercept and analyze network traffic using Python, craft and spoof wireless frames to attack wireless and Bluetooth devices, and how to data-mine popular social media websites and evade modern anti-virus.

    As the first act of flight, a rocket launch requires an entire set of systems to lift the vehicle into orbit-not just the vehicle itself, but all the systems needed for smoothly moving off the ground into space. Likewise, your project needs its entire set of supporting systems in place to begin a successful journey to delivery. Whatever you call it (project kickoff, bootcamp, inception, or jump start), liftoff gives your team its trajectory, and launches your project. This critical practice informs, inspires, and aligns everyone to a singular purpose: the successful delivery of software. This success is in your hands! Agile veterans Diana Larsen and Ainsley Nies teach you how to organize and conduct liftoffs, hold team activities to discover what's most important, and offer a working framework for effective and lightweight agile chartering.

    The book drives to the heart of the exciting debate on the origins of life and maintenance of order in complex biological systems. It focuses on the concept of self-organization: the spontaneous emergence of order that is widely observed throughout nature Kauffman argues that self-organization plays an important role in the Darwinian process of natural selection. Yet until now no systematic effort has been made to incorporate the concept of self-organization into evolutionary theory. The construction requirements which permit complex systems to adapt are poorly understood, as is the extent to which selection itself can yield systems able to adapt more successfully. This book explores these themes. It shows how complex systems, contrary to expectations, can spontaneously exhibit stunning degrees of order, and how this order, in turn, is essential for understanding the emergence and development of life on Earth. Topics include the new biotechnology of applied molecular evolution, with its important implications for developing new drugs and vaccines; the balance between order and chaos observed in many naturally occurring systems; new insights concerning the predictive power of statistical mechanics in biology; and other major issues. Indeed, the approaches investigated here may prove to be the new center around which biological science itself will evolve. The work is written for all those interested in the cutting edge of research in the life sciences.

    This text is split into distinct sections, each concentrating on a core angle of the language. The book also contains sections for Web and application development, the two most popular uses for Python. It is designed to teach a programmer how to use Python by explaining the mechanics of Python. The appendixes offer a quick guide to the main features of the Python language, as well as additional guides to non-essential systems such as the IDLE development environment and general guidelines for migrating from another language.

    Federal Reserve Bank sneezes the global economy catches cold, read this book," writes John L. Casti (Santa Fe Institute). This "cogent and engaging" (Nature) work presents the fundamental principles of the emerging field of "small-worlds" theory—the idea that a hidden pattern is the key to how networks interact and exchange information, whether that network is the information highway or the firing of neurons in the brain. Mathematicians, physicists, computer scientists, and social scientists are working to decipher this complex organizational system, for it may yield a blueprint of dynamic interactions within our physical as well as social worlds.Highlighting groundbreaking research behind network theory, "Mark Buchanan's graceful, lucid, nontechnical and entertaining prose" (Mark Granovetter) documents the mounting support among various disciplines for the small-worlds idea and demonstrates its practical applications to diverse problems—from the volatile global economy or the Human Genome Project to the spread of infectious disease or ecological damage. Nexus is an exciting introduction to the hidden geometry that weaves our lives so inextricably together.

    Hosts behind the firewall have no defenses of their own, so when a host in the trusted zone is breached, access to your data center is not far behind. This practical book introduces you to the zero trust model, a method that treats all hosts as if they're internet-facing, and considers the entire network to be compromised and hostile.Authors Evan Gilman and Doug Barth show you how zero trust lets you focus on building strong authentication, authorization, and encryption throughout, while providing compartmentalized access and better operational agility. You'll learn the architecture of a zero trust network, including how to build one using currently available technology.Understand how the zero trust model embeds security within the system's operation, rather than layering it on topExamine the fundamental concepts at play in a zero trust network, including network agents and trust enginesUse existing technology to establish trust among the actors in a networkLearn how to migrate from a perimeter-based network to a zero trust network in productionExplore case studies of zero trust on the client side (Google) and on the server (PagerDuty)

    Bleak tools of the cold war, they embodied the rigid organization and mechanical conformity that made the military-industrial complex possible. But by the 1990s—and the dawn of the Internet—computers started to represent a very different kind of world: a collaborative and digital utopia modeled on the communal ideals of the hippies who so vehemently rebelled against the cold war establishment in the first place. From Counterculture to Cyberculture is the first book to explore this extraordinary and ironic transformation. Fred Turner here traces the previously untold story of a highly influential group of San Francisco Bay–area entrepreneurs: Stewart Brand and the Whole Earth network. Between 1968 and 1998, via such familiar venues as the National Book Award–winning Whole Earth Catalog, the computer conferencing system known as WELL, and, ultimately, the launch of the wildly successful Wired magazine, Brand and his colleagues brokered a long-running collaboration between San Francisco flower power and the emerging technological hub of Silicon Valley. Thanks to their vision, counterculturalists and technologists alike joined together to reimagine computers as tools for personal liberation, the building of virtual and decidedly alternative communities, and the exploration of bold new social frontiers. Shedding new light on how our networked culture came to be, this fascinating book reminds us that the distance between the Grateful Dead and Google, between Ken Kesey and the computer itself, is not as great as we might think.

    

    Visible Ops is comprised of four prescriptive and self-fueling steps that take an organization from any starting point to a continually improving process. MAKING ITIL ACTIONABLE Although the Information Technology Infrastructure Library (ITIL) provides a wealth of best practices, it lacks prescriptive guidance: What do you implement first, and how do you do it? Moreover, the ITIL books remain relatively expensive to distribute. Other information, publicly available from a variety of sources, is too general and vague to effectively aid organizations that need to start or enhance process improvement efforts. The Visible Ops booklet provides a prescriptive roadmap for organizations beginning or continuing their IT process improvement journey. WHY DO WE NEED VISIBLE OPS? The Visible Ops methodology was developed because there was not a satisfactory answer to the question: "I believe in the need for IT process improvement, but where do I start?" Since 2000, Gene Kim and Kevin Behr have met with hundreds of IT organizations and identified eight high-performing IT organizations with the highest service levels, best security, and best efficiencies. For years, they studied these high-performing organizations to figure out the secrets to their success. Visible Ops codifies how these organizations achieved their transformation from good to great, showing how interested organizations can replicate the key processes of these high-performing organizations in just four steps: 1. Stabilize Patient, Modify First Response - Almost 80% of outages are self-inflicted. The first step is to control risky changes and reduce MTTR by addressing how changes are managed and how problems are resolved. 2. Catch and Release, Find Fragile Artifacts - Often, infrastructure exists that cannot be repeatedly replicated. In this step, we inventory assets, configurations and services, to identify those with the lowest change success rates, highest MTTR and highest business downtime costs. 3. Establish Repeatable Build Library - The highest return on investment is implementing effective release management processes. This step creates repeatable builds for the most critical assets and services, to make it "cheaper to rebuild than to repair." 4. Enable Continuous Improvement - The previous steps have progressively built a closed-loop between the Release, Control and Resolution processes. This step implements metrics to allow continuous improvement of all of these process areas, to best ensure that business objectives are met.
