Completely Revised for the New 2007 Version of the CCNA Exam (#640-802) Cisco networking authority Todd Lammle has completely updated this new edition to cover all of the exam objectives for the latest version of the CCNA exam.

    Stories about weaknesses in cybersecurity like the "Heartbleed" leak, or malicious software on the cash registers at your local Target have become alarmingly common. Even more alarming is the sheer number of victims associated with these crimes--the identities and personal information of millions is stolen outright as criminals drain bank accounts and max out credit cards. The availability of stolen credit card information is now so common that it can be purchased on the black market for as little as four dollars with potentially thousands at stake for the victims. Possibly even more catastrophic are hackers at a national level that have begun stealing national security, or economic and trade secrets. The world economy and geopolitics hang in the balance.In Cyberphobia, Edward Lucas unpacks this shadowy, but metastasizing problem confronting our security--both for individuals and nations. The uncomfortable truth is that we do not take cybersecurity seriously enough. Strong regulations on automotive safety or guidelines for the airline industry are commonplace, but when it comes to the internet, it might as well be the Wild West. Standards of securing our computers and other internet-connected technology are diverse, but just like the rules of the road meant to protect both individual drivers and everyone else driving alongside them, weak cybersecurity on the computers and internet systems near us put everyone at risk. Lucas sounds a compelling and necessary alarm on behalf of cybersecurity and prescribes immediate and bold solutions to this grave threat.

    TCP/IP Protocol Suite teaches students and professionals, with no prior knowledge of TCP/IP, everything they need to know about the subject. This comprehensive book uses hundreds of figures to make technical concepts easy to grasp, as well as many examples, which help tie the material to the real-world. The second edition of TCP/IP Protocol Suite has been fully updated to include all of the recent technology changes in the field. Many new chapters have been added such as one on Mobile IP, Multimedia and Internet, Network Security, and IP over ATM. Additionally, out-of-date material has been overhauled to reflect recent changes in technology.

    He saw at close range the battleground on which adversaries are attacking us: cyberspace.Like the rest of us, governments and corporations inhabit “glass houses,” all but transparent to a new generation of spies who operate remotely from such places as China, the Middle East, Russia, and even France. In this urgent wake-up call, Brenner draws on his extraordinary background to show what we can—and cannot—do to prevent cyber spies and hackers from compromising our security and stealing our latest technology.

    The cause of their failure was a complete mystery.Five months later, a seemingly unrelated event occurred. A computer security firm in Belarus was called in to troubleshoot some computers in Iran that were caught in a reboot loop—crashing and rebooting repeatedly. At first, technicians with the firm believed the malicious code they found on the machines was a simple, routine piece of malware. But as they and other experts around the world investigated, they discovered a virus of unparalleled complexity and mysterious provenance and intent. They had, they soon learned, stumbled upon the world’s first digital weapon.Stuxnet, as it came to be known, was unlike any other virus or worm built before: It was the first attack that reached beyond the computers it targeted to physically destroy the equipment those computers controlled. It was an ingenious attack, jointly engineered by the United States and Israel, that worked exactly as planned, until the rebooting machines gave it all away. And the discovery of Stuxnet was just the beginning: Once the digital weapon was uncovered and deciphered, it provided clues to other tools lurking in the wild. Soon, security experts found and exposed not one but three highly sophisticated digital spy tools that came from the same labs that created Stuxnet. The discoveries gave the world its first look at the scope and sophistication of nation-state surveillance and warfare in the digital age.Kim Zetter, a senior reporter at Wired, has covered hackers and computer security since 1999 and is one of the top journalists in the world on this beat. She was among the first reporters to cover Stuxnet after its discovery and has authored many of the most comprehensive articles about it. In COUNTDOWN TO ZERO DAY: Stuxnet and the Launch of the World’s First Digital Weapon, Zetter expands on this work to show how the code was designed and unleashed and how its use opened a Pandora’s Box, ushering in an age of digital warfare in which any country’s infrastructure—power grids, nuclear plants, oil pipelines, dams—is vulnerable to the same kind of attack with potentially devastating results. A sophisticated digital strike on portions of the power grid, for example, could plunge half the U.S. into darkness for weeks or longer, having a domino effect on all other critical infrastructures dependent on electricity.

    When she arrived at MIT in the 1990s, Alien was quickly drawn to the school’s tradition of high‑risk physical trespassing: the original “hacking.” Within a year, one of her hallmates was dead and two others were arraigned. Alien’s adventures were only just beginning. After a stint at the storied, secretive Los Alamos National Laboratory, Alien was recruited by a top cybersecurity firm where she deployed her cache of virtual weapons—and the trespassing and social engineering talents she had developed while “hacking” at MIT. The company tested its clients’ security by every means possible—not just coding, but donning disguises and sneaking past guards and secretaries into the C‑suite. Alien now runs a boutique hacking outfit that caters to some of the world’s biggest and most vulnerable institutions—banks, retailers, government agencies. Her work combines devilish charm, old‑school deception, and next generation spycraft. In Breaking and Entering, cybersecurity finally gets the rich, character‑driven, fast-paced treatment it deserves.

    She ended up becoming so closely connected to Anonymous that the tricky story of her inside–outside status as Anon confidante, interpreter, and erstwhile mouthpiece forms one of the themes of this witty and entirely engrossing book.The narrative brims with details unearthed from within a notoriously mysterious subculture, whose semi-legendary tricksters—such as Topiary, tflow, Anachaos, and Sabu—emerge as complex, diverse, politically and culturally sophisticated people. Propelled by years of chats and encounters with a multitude of hackers, including imprisoned activist Jeremy Hammond and the double agent who helped put him away, Hector Monsegur, Hacker, Hoaxer, Whistleblower, Spy is filled with insights into the meaning of digital activism and little understood facets of culture in the Internet age, including the history of “trolling,” the ethics and metaphysics of hacking, and the origins and manifold meanings of “the lulz.”

    Foremost on that list is mobility, since going wireless frees you from the tether of an Ethernet cable at a desk. But that's just the tip of the cable-free iceberg. Wireless networks are also more flexible, faster and easier for you to use, and more affordable to deploy and maintain.The de facto standard for wireless networking is the 802.11 protocol, which includes Wi-Fi (the wireless standard known as 802.11b) and its faster cousin, 802.11g. With easy-to-install 802.11 network hardware available everywhere you turn, the choice seems simple, and many people dive into wireless computing with less thought and planning than they'd give to a wired network. But it's wise to be familiar with both the capabilities and risks associated with the 802.11 protocols.

    The world has become a law enforcer's nightmare and every criminal's dream. We bank online; shop online; date, learn, work and live online. But have the institutions that keep us safe on the streets learned to protect us in the burgeoning digital world? Have we become complacent about our personal security--sharing our thoughts, beliefs and the details of our daily lives with anyone who might care to relieve us of them?In this fascinating and compelling book, Misha Glenny, author of the international best seller "McMafia," explores the three fundamental threats facing us in the twenty-first century: cybercrime, cyberwarfare and cyberindustrial espionage. Governments and the private sector are losing billions of dollars each year fighting an ever-morphing, often invisible and often supersmart new breed of criminal: the hacker. Glenny has traveled and trawled the world. By exploring the rise and fall of the criminal website DarkMarket he has uncovered the most vivid, alarming and illuminating stories. Whether JiLsi or Matrix, Iceman, Master Splynter or Lord Cyric; whether Detective Sergeant Chris Dawson in Scunthorpe, England, or Agent Keith Mularski in Pittsburgh, Pennsylvania, Glenny has tracked down and interviewed all the players--the criminals, the geeks, the police, the security experts and the victims--and he places everyone and everything in a rich brew of politics, economics and history.The result is simply unputdownable. DarkMarket is authoritative and completely engrossing. It's a must-read for everyone who uses a computer: the essential crime book for our times.

    Few composers write more than one or two symphonies in their lifetimes. Beethoven spent a year on his shorter symphonies but more than six years on his 9th Symphony. But Georg Philipp Telemann composed at least 200 overtures in a two-year period. Over his lifetime Telemann's oeuvre consists of more than 3,000 pieces, although “only” 800 survive to this day. He was not the only person whose productivity defied all reason. Greek scientist Archimedes discovered mathematical phenomena that weren't confirmed for 17 centuries. Isaac Newton invented classical physics and was one of the inventors of calculus. Benjamin Franklin wrote, published, politicked, invented, experimented, and humored, sometimes all at the same time. Theodore Roosevelt was the first American to earn a belt in judo, hunted, wrote numerous books, and read four hours a day, even during the busiest moments of his political life. This book will explore the lives of the 18 most productive people in history. We will look at the cultures into which they were born and see the methods that they used to achieve such sweeping results. Perhaps we can also create enough time to focus on the tasks in life that are truly meaningful.

    In Turing’s Cathedral, George Dyson focuses on a small group of men and women, led by John von Neumann at the Institute for Advanced Study in Princeton, New Jersey, who built one of the first computers to realize Alan Turing’s vision of a Universal Machine. Their work would break the distinction between numbers that mean things and numbers that do things—and our universe would never be the same. Using five kilobytes of memory (the amount allocated to displaying the cursor on a computer desktop of today), they achieved unprecedented success in both weather prediction and nuclear weapons design, while tackling, in their spare time, problems ranging from the evolution of viruses to the evolution of stars. Dyson’s account, both historic and prophetic, sheds important new light on how the digital universe exploded in the aftermath of World War II. The proliferation of both codes and machines was paralleled by two historic developments: the decoding of self-replicating sequences in biology and the invention of the hydrogen bomb. It’s no coincidence that the most destructive and the most constructive of human inventions appeared at exactly the same time.  How did code take over the world? In retracing how Alan Turing’s one-dimensional model became John von Neumann’s two-dimensional implementation, Turing’s Cathedral offers a series of provocative suggestions as to where the digital universe, now fully three-dimensional, may be heading next.
