Secure your computer network with SSH! With transparent, strong encryption, reliable public-key authentication, and a highly configurable client/server architecture, SSH (Secure Shell) is a popular, robust, TCP/IP-based solution to many network security and privacy concerns. It supports secure remote logins, secure file transfer between computers, and a unique "tunneling" capability that adds encryption to otherwise insecure network applications. Best of all, SSH is free, with feature-filled commercial versions available as well.

SSH: The Secure Shell: The Definitive Guide covers the Secure Shell in detail for both system administrators and end users. It demystifies the SSH man pages and includes thorough coverage of:

SSH1, SSH2, OpenSSH, and F-Secure SSH for Unix, plus Windows and Macintosh products: the basics, the internals, and complex applications.Configuring SSH servers and clients, both system-wide and per user, with recommended settings to maximize security.Advanced key management using agents, agent forwarding, and forced commands.Forwarding (tunneling) of TCP and X11 applications in depth, even in the presence of firewalls and network address translation (NAT).Undocumented behaviors of popular SSH implementations.Installing and maintaining SSH systems.

Whether you're communicating on a small LAN or across the Internet, SSH can ship your data from "here" to "there" efficiently and securely. So throw away those insecure .rhosts and hosts.equiv files, move up to SSH, and make your network a safe place to live and work.

"The book you are about to read will arm you with the knowledge you need to defend your network from attackers—both the obvious and the not so obvious....If you are new to network security, don't put this book back on the shelf! This is a great book for beginners and I wish I had access to it many years ago. If you've learned the basics of TCP/IP protocols and run an open source or commercial IDS, you may be asking 'What's next?' If so, this book is for you."

—Ron Gula, founder and CTO, Tenable Network Security, from the Foreword "Richard Bejtlich has a good perspective on Internet security—one that is orderly and practical at the same time. He keeps readers grounded and addresses the fundamentals in an accessible way."

—Marcus Ranum, TruSecure "This book is not about security or network monitoring: It's about both, and in reality these are two aspects of the same problem. You can easily find people who are security experts or network monitors, but this book explains how to master both topics."

—Luca Deri, ntop.org "This book will enable security professionals of all skill sets to improve their understanding of what it takes to set up, maintain, and utilize a successful network intrusion detection strategy."

—Kirby Kuehl, Cisco Systems Every network can be compromised. There are too many systems, offering too many services, running too many flawed applications. No amount of careful coding, patch management, or access control can keep out every attacker. If prevention eventually fails, how do you prepare for the intrusions that will eventually happen? Network security monitoring (NSM) equips security staff to deal with the inevitable consequences of too few resources and too many responsibilities. NSM collects the data needed to generate better assessment, detection, and response processes—resulting in decreased impact from unauthorized activities. In The Tao of Network Security Monitoring, Richard Bejtlich explores the products, people, and processes that implement the NSM model. By focusing on case studies and the application of open source tools, he helps you gain hands-on knowledge of how to better defend networks and how to mitigate damage from security incidents. Inside, you will find in-depth information on the following areas. The NSM operational framework and deployment considerations. How to use a variety of open-source tools—including Sguil, Argus, and Ethereal—to mine network traffic for full content, session, statistical, and alert data. Best practices for conducting emergency NSM in an incident response scenario, evaluating monitoring vendors, and deploying an NSM architecture. Developing and applying knowledge of weapons, tactics, telecommunications, system administration, scripting, and programming for NSM. The best tools for generating arbitrary packets, exploiting flaws, manipulating traffic, and conducting reconnaissance. Whether you are new to network intrusion detection and incident response, or a computer-security veteran, this book will enable you to quickly develop and apply the skills needed to detect, prevent, and respond to new and emerging threats.

This book reformulates the sociological  subdiscipline known as the sociology of knowledge.  Knowledge is presented as more than ideology, including as  well false consciousness, propaganda, science and  art.

Some people plan to become administrators. The rest of us are thrust into it: we are webmasters, hobbyists, or just the default "technical people" on staff who are expected to keep things running. After some stumbling around repeating the same steps over and over again (and occasionally paying the price when we forget one), we realize that we must automate these tasks, or suffer endless frustration. Thus enters Perl. The Perl programming language is ideal for writing quick yet powerful scripts that automate many administrative tasks. It's modular, it's powerful, and it's perfect for managing systems and services on many platforms. Perl for System Administration is designed for all levels of administrators—from hobbyists to card-carrying SAGE members—sysadmins on multi-platform sites. Written for several different platforms (Unix, Windows NT, and Mac OS), it's a guide to the pockets of administration where Perl can be most useful for sites large and small, including:Filesystem managementUser administration with a dash of XMLDNS and other network name servicesDatabase administration using DBI and ODBCDirectory services and frameworks like LDAP and ADSIUsing email for system administrationWorking with log files of all kindsEach chapter concentrates on a single administrative area, discusses the possible pitfalls, and then shows how Perl comes to the rescue. Along the way we encounter interesting Perl features and tricks, with many extended examples and complete programs. The scripts included in the book can simply be used as written or with minimal adaptation. But it's likely that readers will also get a taste of what Perl can do, and start extending those scripts for tasks that we haven't dreamed of. Perl for System Adminstration doesn't attempt to teach the Perl language, but it is an excellent introduction to the power and flexibility of Perl, and it whets the appetite to learn more. It's for anyone who needs to use Perl for system administration and needs to hit the ground running.

One of the bestselling novels of all time, Dan Brown's The Da Vinci Code has intrigued and thrilled millions of readers around the world. Now all the artwork, symbols, architecture, and historic locations—over 160 images—are beautifully compiled in this full-color collector's edition.

A mind-bending code hidden in the works of Leonardo da Vinci. A desperate race through the cathedrals and castles of Europe. An astonishing truth concealed for centuries… unveiled at last.

While in Paris on business, Harvard symbologist Robert Langdon receives an urgent late-night phone call. The elderly curator of the Louvre has been murdered inside the museum, a baffling cipher found near the body. As Langdon and a gifted French cryptologist, Sophie Neveu, sort through the bizarre riddles, they are stunned to discover a trail of clues hidden in the works of Da Vinci–clues visible for all to see and yet ingeniously disguised by the painter.

The stakes are raised when Langdon uncovers a startling link: the late curator was involved in the Priory of Sion—an actual secret society whose members included Sir Isaac Newton, Botticelli, Victor Hugo, and Da Vinci, among others. Langdon suspects they are on the hunt for a breathtaking historical secret, one that has proven through the centuries to be as enlightening as it is dangerous. In a frantic race through Paris, and beyond, Langdon and Neveu find themselves matching wits with a faceless powerbroker who appears to anticipate their every move. Unless they can decipher the labyrinthine puzzle, the Priory's secret—and an explosive ancient truth—will be lost forever.

Instantly catapulted to the top of the bestseller lists around the world, The Da Vinci Code is simultaneously lightning-paced, intelligent, and intricately layered with remarkable research and detail. From secrets embedded in the Mona Lisa and The Last Supper, to the symbols of ancient Egypt, to the architecture of landmarks such as the Louvre, Westminster Abbey, Rosslyn Chapel, and more, this fully illustrated collector's edition delivers the complete reading experience of Dan Brown's riveting novel—from the opening pages to the unpredictable and stunning conclusion.

Before the multi-million, runaway bestseller The Da Vinci Code, Dan Brown set his razor-sharp research and storytelling skills on the most powerful intelligence organization on earth—the National Security Agency (NSA), an ultra-secret, multibillion-dollar agency many times more powerful than the CIA.When the NSA's invincible code-breaking machine encounters a mysterious code it cannot break, the agency calls its head cryptographer, Susan Fletcher, a brilliant and beautiful mathematician. What she uncovers sends shock waves through the corridors of power. The NSA is being held hostage...not by guns or bombs, but by a code so ingeniously complex that if released it would cripple U.S. intelligence.Caught in an accelerating tempest of secrecy and lies, Susan Fletcher battles to save the agency she believes in. Betrayed on all sides, she finds herself fighting not only for her country but for her life, and in the end, for the life of the man she loves.From the underground hallways of power to the skyscrapers of Tokyo to the towering cathedrals of Spain, a desperate race unfolds. It is a battle for survival—a crucial bid to destroy a creation of inconceivable genius...an impregnable code-writing formula that threatens to obliterate the post-cold war balance of power. Forever.

Bill Bryson is one of the world’s most beloved and bestselling writers. In A Short History of Nearly Everything, he takes his ultimate journey–into the most intriguing and consequential questions that science seeks to answer. It’s a dazzling quest, the intellectual odyssey of a lifetime, as this insatiably curious writer attempts to understand everything that has transpired from the Big Bang to the rise of civilization. Or, as the author puts it, “…how we went from there being nothing at all to there being something, and then how a little of that something turned into us, and also what happened in between and since.” This is, in short, a tall order.

To that end, Bill Bryson apprenticed himself to a host of the world’s most profound scientific minds, living and dead. His challenge is to take subjects like geology, chemisty, paleontology, astronomy, and particle physics and see if there isn’t some way to render them comprehensible to people, like himself, made bored (or scared) stiff of science by school. His interest is not simply to discover what we know but to find out how we know it. How do we know what is in the center of the earth, thousands of miles beneath the surface? How can we know the extent and the composition of the universe, or what a black hole is? How can we know where the continents were 600 million years ago? How did anyone ever figure these things out?

On his travels through space and time, Bill Bryson encounters a splendid gallery of the most fascinating, eccentric, competitive, and foolish personalities ever to ask a hard question. In their company, he undertakes a sometimes profound, sometimes funny, and always supremely clear and entertaining adventure in the realms of human knowledge, as only this superb writer can render it. Science has never been more involving, and the world we inhabit has never been fuller of wonder and delight.
