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.

This new edition of Practical Unix & Internet Security provides detailed coverage of today's increasingly important security and networking issues. Focusing on the four most popular Unix variants today--Solaris, Mac OS X, Linux, and FreeBSD--this book contains new information on PAM (Pluggable Authentication Modules), LDAP, SMB/Samba, anti-theft technologies, embedded systems, wireless and laptop issues, forensics, intrusion detection, chroot jails, telephone scanners and firewalls, virtual and cryptographic filesystems, WebNFS, kernel security levels, outsourcing, legal issues, new Internet protocols and cryptographic algorithms, and much more.

This succinct book departs from other security literature by focusing exclusively on ways to secure Cisco routers, rather than the entire network. The rational is simple: If the router protecting a network is exposed to hackers, then so is the network behind it. This is a reference for protecting the protectors, and author Thomas Akin supplies all the tools necessary to turn a potential vulnerability into a strength.

Electronic commerce is changing the way that businesses and consumers interact with each other; the products they create, buy, and sell; and the way that they communicate, learn, and become informed. How can policymakers position their countries and themselves to take advantage of this new environment? How should policymaking adjust to a more global, more networked, and more information-rich marketplace where relationships and jurisdictions between the governments, businesses, and citizens of different countries increasingly overlap? How can governments effectively harness rapidly changing technologies and partner with both domestic and foreign private sectors to reap the greatest benefits for their constituents?

This primer answers these questions using both general analysis and specific examples. It addresses in particular the needs of policymakers in emerging markets who must formulate and refine policies that affect e-commerce in areas ranging from telecommunications and finance to international trade and domestic distribution as well as taxation and privacy. Companies considering doing business in these economies also will find that the examples offer insights into the issues that policymakers face, the different policy approaches that they choose, and the market opportunities that result as more and more economies embrace global electronic commerce.

This book explains how to plan and build a Virtual Private Network (VPN), a collection of technologies that creates secure connections or "tunnels" over regular Internet lines. It discusses costs, configuration, and how to install and use VPN technologies that are available for Windows NT and Unix, such as PPTP and L2TP, Altavista Tunnel, Cisco PIX, and the secure shell (SSH). New features in the second edition include SSH and an expanded description of the IPSec standard.

The general problem studied by information theory is the reliable transmission of information through unreliable channels. Channels can be unreliable either because they are disturbed by noise or because unauthorized receivers intercept the information transmitted. In the first case, the theory of error-control codes provides techniques for correcting at least part of the errors caused by noise. In the second case cryptography offers the most suitable methods for coping with the many problems linked with secrecy and authentication. Now, both error-control and cryptography schemes can be studied, to a large extent, by suitable geometric models, belonging to the important field of finite geometries. This book provides an update survey of the state of the art of finite geometries and their applications to channel coding against noise and deliberate tampering. The book is divided into two sections, "Geometries and Codes" and "Geometries and Cryptography." The first part covers such topics as Galois geometries, Steiner systems, Circle geometry and applications to algebraic coding theory. The second part deals with unconditional secrecy and authentication, geometric threshold schemes and applications of finite geometry to cryptography. This volume recommends itself to engineers dealing with communication problems, to mathematicians and to research workers in the fields of algebraic coding theory, cryptography and information theory.

Though rootkits have a fairly negative image, they can be used for both good and evil. Designing BSD Rootkits arms you with the knowledge you need to write offensive rootkits, to defend against malicious ones, and to explore the FreeBSD kernel and operating system in the process. Organized as a tutorial, Designing BSD Rootkits will teach you the fundamentals of programming and developing rootkits under the FreeBSD operating system. Author Joseph Kong's goal is to make you smarter, not to teach you how to write exploits or launch attacks. You'll learn how to maintain root access long after gaining access to a computer and how to hack FreeBSD. Kongs liberal use of examples assumes no prior kernel-hacking experience but doesn't water down the information. All code is thoroughly described and analyzed, and each chapter contains at least one real-world application.Included: The fundamentals of FreeBSD kernel module programming Using call hooking to subvert the FreeBSD kernel Directly manipulating the objects the kernel depends upon for its internal record-keeping Patching kernel code resident in main memory; in other words, altering the kernel's logic while it's still running How to defend against the attacks described Hack the FreeBSD kernel for yourself

This book presents several novel approaches to model the interaction between the attacker and the defender and assess the security of Vehicular Ad Hoc Networks (VANETs). The first security assessment approach is based on the attack tree security assessment model, which leverages tree based methods to analyze the risk of the system and identify the possible attacking strategies the adversaries may launch. To further capture the interaction between the attacker and the defender, the authors propose to utilize the attack-defense tree model to express the potential countermeasures which could mitigate the system. By considering rational participants that aim to maximize their payoff function, the brief describes a game-theoretic analysis approach to investigate the possible strategies that the security administrator and the attacker could adopt. A phased attack-defense game allows the reader to model the interactions between the attacker and defender for VANET security assessment. The brief offers a variety of methods for assessing the security of wireless networks. Professionals and researchers working on the defense of VANETs will find this material valuable.

Stefan Brands proposes cryptographic building blocks for the design of digital certificates that preserve privacy without sacrificing security. As paper-based communication and transaction mechanisms are replaced by automated ones, traditional forms of security such as photographs and handwritten signatures are becoming outdated. Most security experts believe that digital certificates offer the best technology for safeguarding electronic communications. They are already widely used for authenticating and encrypting email and software, and eventually will be built into any device or piece of software that must be able to communicate securely. There is a serious problem, however, with this unavoidable trend: unless drastic measures are taken, everyone will be forced to communicate via what will be the most pervasive electronic surveillance tool ever built. There will also be abundant opportunity for misuse of digital certificates by hackers, unscrupulous employees, government agencies, financial institutions, insurance companies, and so on.In this book Stefan Brands proposes cryptographic building blocks for the design of digital certificates that preserve privacy without sacrificing security. Such certificates function in much the same way as cinema tickets or subway tokens: anyone can establish their validity and the data they specify, but no more than that. Furthermore, different actions by the same person cannot be linked. Certificate holders have control over what information is disclosed, and to whom. Subsets of the proposed cryptographic building blocks can be used in combination, allowing a cookbook approach to the design of public key infrastructures. Potential applications include electronic cash, electronic postage, digital rights management, pseudonyms for online chat rooms, health care information storage, electronic voting, and even electronic gambling.

Hailed as "a chilling portrait" by The Boston Globe and "a crafty thriller" by Newsweek, this astonishing story of an obsessive hacker promises to change the way you look at the Internet forever.

At Large chronicles the massive manhunt that united hard-nosed FBI agents, computer nerds, and uptight security bureaucrats against an elusive computer outlaw who broke into highly secured computer systems at banks, universities, federal agencies, and top-secret military weapons-research sites. Here is "a real-life tale of cops vs. hackers, by two technology writers with a flair for turning a complicated crime and investigation into a fast-moving edge-of-your-seat story" (Kirkus Reviews, starred). At Large blows the lid off the frightening vulnerability of the global online network, which leaves not only systems, but also individuals, exposed.
