When it comes to network security, many users and administrators are running scared, and justifiably so. The sophistication of attacks against computer systems increases with each new Internet worm.What's the worst an attacker can do to you? You'd better find out, right? That's what "Security Warrior" teaches you. Based on the principle that the only way to defend yourself is to understand your attacker in depth, "Security Warrior" reveals how your systems can be attacked. Covering everything from reverse engineering to SQL attacks, and including topics like social engineering, antiforensics, and common attacks against UNIX and Windows systems, this book teaches you to know your enemy and how to be prepared to do battle.
"Security Warrior" places particular emphasis on reverse engineering. RE is a fundamental skill for the administrator, who must be aware of all kinds of malware that can be installed on his machines -- trojaned binaries, "spyware" that looks innocuous but that sends private data back to its creator, and more. This is the only book to discuss reverse engineering for Linux or Windows CE. It's also the only book that shows you how SQL injection works, enabling you to inspect your database and web applications for vulnerability.
"Security Warrior" is the most comprehensive and up-to-date book covering the art of computer war: attacks against computer systems and their defenses. It's often scary, and never comforting. If you're on the front lines, defending your site against attackers, you need this book. On your shelf--and in your hands.

Think there's no malicious software on your computer? PC Magazine thinks you should think again.
Scans by ISPs have revealed as many as twenty-eight spyware programs running on the average home computer--like yours. That's a lot of people prying into what's on your PC, and a DSL or cable connection is a virtual welcome mat. But by following Ed Tittel's advice, you can learn how invasions occur, spot an infestation, repair damage that's already done, and slam the door on those who want to hijack your PC--along with your wallet.
Here's how you can
* Learn to recognize when a Trojan horse, a virus, adware, or spyware has invaded your PC
* Get the tools that can cure an infection
* Dig into the Windows Registry to remove the nastiest of bugs
* Prevent a recurrence with personal firewalls and protective software
* Deal with the onslaught of spam
* Keep your defenses up-to-date
Give it the boot
If you believe you've caught something and you're willing to kiss everything goodbye that you've added to or changed ... since the last time you booted up your computer ... try this. While Windows is first booting up, hit the F8 key .... Choose the Last Known Good Configuration option, and Windows should boot running the version of the Registry that existed the last time your system booted--that is, before you got infected.

In the year 2010, computers are the new superpowers. Those who control them control the world. To enforce the Net Laws, Congress has created the ultimate computer security agency within the FBI: Net Force.
Minor viruses are eating away at the Net Force computers. The e-mial shut-downs and flickering monitors are hardly emergencies -- but they've been keeping the tech department hopping. Same with the sudden rash of time-consuming lawsuits. No one in the Net Froce has a moment to spare, which is exactly the way Mitchell Townsend Ames wants it. Because when the shadowy mastermind launches his master plan, he wants Net Force to be looking the other way...

In Transmission, award-winning writer Hari Kunzru takes an ultra-contemporary turn with the story of an Indian computer programmer whose luxurious fantasies about life in America are shaken when he accepts a California job offer.Lonely and naïve, Arjun spends his days as a lowly assistant virus- tester, pining away for his free-spirited colleague Christine. Arjun gets laid off like so many of his Silicon Valley peers, and in an act of desperation to keep his job, he releases a mischievous but destructive virus around the globe that has major unintended consequences. As world order unravels, so does Arjun’s sanity, in a rollicking cataclysm that reaches Bollywood and, not so coincidentally, the glamorous star of Arjun’s favorite Indian movie.

Your IDS Just Detected an Attack: Was it Successful? This book is about one of the most crucial aspects of system and security management: host integrity protection. Fundamentally, host integrity protection is all about understanding the changes that occur on your system--friendly or hostile, deliberate or accidental--and understanding the impact of those changes. In other words, it's change control in a potentially hostile environment. Best of all, this book is written by Brian Wotring, who has designed and deployed host integrity monitoring systems, used them, and relied on their results. It's hard to overstate the value of such experience. Books like the one you're holding are the survival kits for the future of computing. They're full of the important clues that you're going to need if you want to be one of the survivors instead of the statistics.--From the Foreword by Marcus J. Ranum

This book deals with computer viruses envisaged from three different points of view, namely the theoretical fundamentals of computer virology, algorithmic and practical aspects of viruses and their potential applications to various areas. The theoretical formalization by means of Turing machines, self-reproducing automata and recursive functions enable a precise and exhaustive description of the different types of malware. It follows that the main stakes of computer defense and antiviral fighting are easily highlighted. Detailed analysis of the source code for representative members of each virus/worm family allows the reader to grasp the basic algorithmic aspects involved in self-reproducing codes. The C programming language has been systematically used for a better understanding of the considered codes.
