Book Synopsis Steal This Computer Book 4.0 by : Wallace Wang
Download or read book Steal This Computer Book 4.0 written by Wallace Wang and published by No Starch Press. This book was released on 2006-05-06 with total page 384 pages. Available in PDF, EPUB and Kindle. Book excerpt: If you thought hacking was just about mischief-makers hunched over computers in the basement, think again. As seasoned author Wallace Wang explains, hacking can also mean questioning the status quo, looking for your own truths and never accepting at face value anything authorities say or do. The completely revised fourth edition of this offbeat, non-technical book examines what hackers do, how they do it, and how you can protect yourself. Written in the same informative, irreverent, and entertaining style that made the first three editions hugely successful, Steal This Computer Book 4.0 will expand your mind and raise your eyebrows. New chapters discuss the hacker mentality, social engineering and lock picking, exploiting P2P file-sharing networks, and how people manipulate search engines and pop-up ads to obtain and use personal information. Wang also takes issue with the media for "hacking" the news and presenting the public with self-serving stories of questionable accuracy. Inside, you’ll discover: –How to manage and fight spam and spyware –How Trojan horse programs and rootkits work and how to defend against them –How hackers steal software and defeat copy-protection mechanisms –How to tell if your machine is being attacked and what you can do to protect it –Where the hackers are, how they probe a target and sneak into a computer, and what they do once they get inside –How corporations use hacker techniques to infect your computer and invade your privacy –How you can lock down your computer to protect your data and your personal information using free programs included on the book’s CD If you’ve ever logged onto a website, conducted an online transaction, sent or received email, used a networked computer or even watched the evening news, you may have already been tricked, tracked, hacked, and manipulated. As the saying goes, just because you’re paranoid doesn’t mean they aren’t after you. And, as Wallace Wang reveals, they probably are. The companion CD contains hundreds of megabytes of 100% FREE hacking and security related programs, like keyloggers, spyware stoppers, port blockers, IP scanners, Trojan horse detectors, and much, much more. CD compatible with Windows, Mac, and Linux.
Book Synopsis Exploding the Phone by : Phil Lapsley
Download or read book Exploding the Phone written by Phil Lapsley and published by Open Road + Grove/Atlantic. This book was released on 2013-02-05 with total page 432 pages. Available in PDF, EPUB and Kindle. Book excerpt: “A rollicking history of the telephone system and the hackers who exploited its flaws.” —Kirkus Reviews, starred review Before smartphones, back even before the Internet and personal computers, a misfit group of technophiles, blind teenagers, hippies, and outlaws figured out how to hack the world’s largest machine: the telephone system. Starting with Alexander Graham Bell’s revolutionary “harmonic telegraph,” by the middle of the twentieth century the phone system had grown into something extraordinary, a web of cutting-edge switching machines and human operators that linked together millions of people like never before. But the network had a billion-dollar flaw, and once people discovered it, things would never be the same. Exploding the Phone tells this story in full for the first time. It traces the birth of long-distance communication and the telephone, the rise of AT&T’s monopoly, the creation of the sophisticated machines that made it all work, and the discovery of Ma Bell’s Achilles’ heel. Phil Lapsley expertly weaves together the clandestine underground of “phone phreaks” who turned the network into their electronic playground, the mobsters who exploited its flaws to avoid the feds, the explosion of telephone hacking in the counterculture, and the war between the phreaks, the phone company, and the FBI. The product of extensive original research, Exploding the Phone is a groundbreaking, captivating book that “does for the phone phreaks what Steven Levy’s Hackers did for computer pioneers” (Boing Boing). “An authoritative, jaunty and enjoyable account of their sometimes comical, sometimes impressive and sometimes disquieting misdeeds.” —The Wall Street Journal “Brilliantly researched.” —The Atlantic “A fantastically fun romp through the world of early phone hackers, who sought free long distance, and in the end helped launch the computer era.” —The Seattle Times

Book Synopsis Handbook of Electronic Security and Digital Forensics by : Hamid Jahankhani
Download or read book Handbook of Electronic Security and Digital Forensics written by Hamid Jahankhani and published by World Scientific. This book was released on 2010 with total page 708 pages. Available in PDF, EPUB and Kindle. Book excerpt: The widespread use of information and communications technology (ICT) has created a global platform for the exchange of ideas, goods and services, the benefits of which are enormous. However, it has also created boundless opportunities for fraud and deception. Cybercrime is one of the biggest growth industries around the globe, whether it is in the form of violation of company policies, fraud, hate crime, extremism, or terrorism. It is therefore paramount that the security industry raises its game to combat these threats. Today's top priority is to use computer technology to fight computer crime, as our commonwealth is protected by firewalls rather than firepower. This is an issue of global importance as new technologies have provided a world of opportunity for criminals. This book is a compilation of the collaboration between the researchers and practitioners in the security field; and provides a comprehensive literature on current and future e-security needs across applications, implementation, testing or investigative techniques, judicial processes and criminal intelligence. The intended audience includes members in academia, the public and private sectors, students and those who are interested in and will benefit from this handbook.

Download or read book Information Security and Digital Forensics written by Dasun Weerasinghe and published by Springer Science & Business Media. This book was released on 2010-01-13 with total page 191 pages. Available in PDF, EPUB and Kindle. Book excerpt: ISDF 2009, the First International Conference on Information Security and Digital Forensics, was held at City University London during September 7-8, 2009. The c- ference was organized as a meeting point for leading national and international - perts of information security and digital forensics. The conference was rewarding in many ways; ISDF 2009 was an exciting and vibrant event, with 4 keynote talks, 25 invited talks and 18 full-paper presentations and those attending had the opportunity to meet and talk with many distinguished people who are responsible for shaping the area of information security. This conference was organized as part of two major research projects funded by the UK Engineering and Physical Sciences Research Council in the areas of Security and Digital Forensics. I would like to thank all the people who contributed to the technical program. The most apparent of these are the Indian delegates who all accepted our invite to give presentations at this conference. Less apparent perhaps is the terrific work of the members of the Technical Program Committee, especially in reviewing the papers, which is a critical and time-consuming task. I would like to thank Raj Rajarajan (City University London) for making the idea of the ISDF 2009 conference a reality with his hard work. Last but not least, I would like to thank all the authors who submitted papers, making the conference possible, and the authors of accepted papers for their cooperation. Dasun Weerasinghe
