Virtual Honeypots: From Botnet Tracking to Intrusion Detection

Praise for Virtual Honeypots "A power-packed resource of technical, insightful information that unveils the world of honeypots in front of the reader’s eyes. Free download Virtual Honeypots books collection in PDF, EPUB, FB2, MOBI, and TXT formats. —Lenny Zeltser, Information Security Practice Leader at Gemini Systems "This is one of the must-read security books of the year." —Cyrus Peikari, CEO, Airscanner Mobile Security, author, security warrior "This book clearly ranks as one of the most authoritative in the field of honeypots. It is comprehensive and well written. The authors provide us with an insider’s look at virtual honeypots and even help us in setting up and understanding an otherwise very complex technology. Best deals ebooks download Virtual Honeypots on amazon. —Stefan Kelm, Secorvo Security Consulting "Virtual Honeypots is the best reference for honeypots today. Security experts Niels Provos and Thorsten Holz cover a large breadth of cutting-edge topics, from low-interaction honeypots to botnets and malware. If you want to learn about the latest types of honeypots, how they work, and what they can do for you, this is the resource you need." —Lance Spitzner, Founder, Honeynet Project "Whether gathering intelligence for research and defense, quarantining malware outbreaks within the enterprise, or tending hacker ant farms at home for fun, you’ll find many practical techniques in the black art of deception detailed in this book. Honeypot magic revealed!" —Doug Song, Chief Security Architect, Arbor Networks "Seeking the safest paths through the unknown sunny islands called honeypots? Trying to avoid greedy pirates catching treasures deeper and deeper beyond your ports? With this book, any reader will definitely get the right map to handle current cyber-threats. Designed by two famous white hats, Niels Provos and Thorsten Holz, it carefully teaches everything from the concepts to practical real-life examples with virtual honeypots. The main strength of this book relies in how it covers so many uses of honeypots: improving intrusion detection systems, slowing down and following incoming attackers, catching and analyzing 0-days or malwares or botnets, and so on. Sailing the high seas of our cyber-society or surfing the Net, from students to experts, it’s a must-read for people really aware of computer security, who would like to fight against black-hats flags with advanced modern tools like honeypots." —Laurent Oudot, Computer Security Expert, CEA "Provos and Holz have written the book that the bad guys don’t want you to read. This detailed and comprehensive look at honeypots provides step-by-step instructions on tripping up attackers and learning their tricks while lulling them into a false sense of security. Whether you are a practitioner, an educator, or a student, this book has a tremendous amount to offer. The underlying theory of honeypots is covered, but the majority of the text is a ‘how-to’ guide on setting up honeypots, configuring them, and getting the most out of these traps, while keeping actual systems safe. Not since the invention of the firewall has a tool as useful as this provided security specialists with an edge in the never-ending arms race to secure computer systems. Virtual Honeypots is a must-read and belongs on the bookshelf of anyone who is serious about security." —Aviel D. Rubin, Ph.D., Computer Science Professor and Technical Director of the Information Security Institute at Johns Hopkins University, and President and Founder, Independent Security Evaluators "An awesome coverage of modern honeypot technologies, both conceptual and practical." —Anton Chuvakin "Honeypots have grown from simple geek tools to key components in research and threat monitoring at major entreprises and security vendors. Thorsten and Niels comprehensive coverage of tools and techniques takes you behind the scene with real-world examples of deployment, data acquisition, and analysis." —Nicolas Fischbach, Senior Manager, Network Engineering Security, COLT Telecom, and Founder of Sécurité.Org Honeypots have demonstrated immense value in Internet security, but physical honeypot deployment can be prohibitively complex, time-consuming, and expensive. Now, there’s a breakthrough solution. Virtual honeypots share many attributes of traditional honeypots, but you can run thousands of them on a single system-making them easier and cheaper to build, deploy, and maintain. In this hands-on, highly accessible book, two leading honeypot pioneers systematically introduce virtual honeypot technology. One step at a time, you’ll learn exactly how to implement, configure, use, and maintain virtual honeypots in your own environment, even if you’ve never deployed a honeypot before. You’ll learn through examples, including Honeyd, the acclaimed virtual honeypot created by coauthor Niels Provos. The authors also present multiple real-world applications for virtual honeypots, including network decoy, worm detection, spam prevention, and network simulation. After reading this book, you will be able to Compare high-interaction honeypots that provide real systems and services and the low-interaction honeypots that emulate them Install and configure Honeyd to simulate multiple operating systems, services, and network environments Use virtual honeypots to capture worms, bots, and other malware Create high-performance "hybrid" honeypots that draw on technologies from both low- and high-interaction honeypots Implement client honeypots that actively seek out dangerous Internet locations Understand how attackers identify and circumvent honeypots Analyze the botnets your honeypot identifies, and the malware it captures Preview the future evolution of both virtual and physical honeypots Virtual Honeypots: From Botnet Tracking to Intrusion Detection with free ebook downloads available via rapidshare, mediafire, 4shared, and hotfile.

Free download Leading the Virtual Workforce books collection in PDF, EPUB, FB2, MOBI, and TXT formats. Once again, Lojeski has a fresh take on what it takes to lead today's widely dispersed workforce."
—Ellen Pearlman, former editor-in-chief, CIO Insight magazine"Karen Lojeski has distilled the essence of the leader's role in 'managing' virtual teams. Her very relevant case stories illustrate that to be successful, the authentic leader must be able to create context and a collaborative lexicon for virtual knowledge sharing and must work diligently to build the social capital that is so vital to the success of virtual work groups. Karen's key contribution in this and her previous book, Uniting the Virtual Workforce, is the 'discovery' and clear articulation of her theory of the Virtual Distance Index, which leaders can use to measure and manage the process of virtual teamwork. Best deals ebooks download Leading the Virtual Workforce on amazon.
—Dave Davison, Chairman, Virtual Visuals Inc."I agree entirely with Karen when she says that today, more than ever, effective leaders are desperately needed. She skillfully defines the dislocation and demarcation of leaders from followers through the 'Virtual Distance,' and yet paradoxically calls leaders to 'stoke the flames of innovation and cooperation in a complex, interwoven world.' This gives rise to her exploration of the Virtual Distance Leader. As Karen points out, the twenty-first-century leader must, amidst the conditions of pressure, change, and transformation, bring human endeavor and action to value and meaning for others."

Virtual Private Networks for Dummies

Let’s face it: the information age makes dummies of us all at some point. Free download Virtual Private Networks for Dummies books collection in PDF, EPUB, FB2, MOBI, and TXT formats. One thing we can say for sure, though, about things related to the Internet is that their best strengths are often also their worst weaknesses. This goes for virtual private networks (VPNs). They may reach a wide base of customers – but can also be vulnerable to viruses, hackers, spoofers, and other shady online characters and entities. VPNs may allow for super-efficient communication between customer and company – but they rely on information which, if compromised, can cause huge losses. Best deals ebooks download Virtual Private Networks for Dummies on amazon.The Internet is still a frontier – sometimes so wide open it leaves us bewildered – and, like any frontier, the risks go hand in hand with potentially huge rewards.Virtual Private Networks for Dummies offers you a no-nonsense, practical guide to evaluating your company’s need for a VPN, understanding what it takes to implement one, and undertaking the challenging quest to set it up, make it work, and keep it safe. Whether you’re the resident expert leading the project team, or you just want to learn what makes e-commerce tick, this detailed, from-the-ground-up guide will soon have you comfortably conceptualizing:Security goals and strategiesThe evolution of VPNsPrivacy in VPNsExtranetsRemote-Access VPNsFundingCustom network solutions designTesting VPNsAnd moreWith new products and technologies offering supposedly revolutionary solutions to IT departments every day, this book focuses on the real world – you know, the one full of obstacles, mishaps, threats, delays, and errors – and gives you the background knowledge to make decisions for yourself about your VPN needs. Written with a dash of humor, Virtual Private Networks for Dummies contains both technical detail (standards, protocols, etc.) and more general concepts (such as conducting cost-benefit analyses). This clear, authoritative guide will have you securely and cost-effectively networking over the Internet in no time.Shockingly short on implementation details, Virtual Private Networks for Dummies tries to craft a scattershot collection of facts and references into an introduction to virtual private networks (VPNs). That's not to say that this book is insubstantial, because it's not; probably, you'll learn something about networking, cryptography, authentication infrastructures, and other aspects of VPN engineering. Also, it's done a good job of compiling references to VPN resources on the Internet, so you'll have plenty of surfing to do. But it never explains how to build a VPN--or even the simplest laboratory simulation of one--and that's precisely the kind of how-to information that buyers of this book will want. True enough: every situation that calls for a VPN is different; and, if the book had shown how to implement a VPN with one turnkey solution, users of the others would complain. But even the narrowest example would have been better than some of the stuff that fills these pages. At one point, the reader is walked through the process of encoding and decoding a plain-text message--by hand--by using a shared private key. Spare us, please. The book gives the vital Layer 2 Transport Protocol all of two short paragraphs. Sections on public-key encryption and digital certificates do a good job of unraveling perennially misunderstood processes, but they don't offset the lack of details on VPN. --David Wall Topics covered: Aspects of virtual private networks (VPNs), organized to get potential VPN implementers thinking about security and other design issues. Specifically, Public-Key Infrastructure (PKI); digital certificates; turnkey VPN packages; and a lot of general stuff about what VPNs are good for, and how to design a good one.

Building Linux Virtual Private Networks (VPNs)

Building Linux Virtual Private Networks (VPNs) covers the most popular VPN technologies available for the Linux platform. Free download Building Linux Virtual Private Networks books collection in PDF, EPUB, FB2, MOBI, and TXT formats. In the early chapters the theory behind VPNs is discussed, including needs and uses. Common network and host configurations are also covered. Subsequent chapters drill down into the implementation and configuration of specific software packages. Specific, detailed instructions are included as well as troubleshooting information. Best deals ebooks download Building Linux Virtual Private Networks on amazon.This book will be an indispensable resource for anyone who wants to implement a Linux-based VPN. This book will meet the needs of anyone, from the Linux user to the experienced administrator to the security professional. --Oleg Kolesnikov A virtual private network (VPN) enables computers to access remote resources--like the mail store on another office's mail server--from a geographically remote location. Rather than access the files over a private (and expensive) wide area network (WAN) link, however, a VPN makes its data transmissions across the open Internet. The magic is in making the communications secure, a critical job that requires a tunneling protocol that implements encryption. Building Linux Virtual Private Networks shows you how to set up VPNs without spending a lot of money, and without compromising ease of use or security. Oleg Kolesnikov and Brian Hatch emphasize network-to-network connectivity--fixed links between sites--rather than network-to-client connections. They show you how to use Linux to build a secure system of permanent--yet virtual--data links. There's coverage, for example, of the PoPToP daemon for handling Point-to-Point Tunneling Protocol (PPTP), but there's no coverage of non-Linux clients with which to connect it.There's a nice balance of managerial information (useful for justifying a VPN, and a Linux one in particular, to your boss) and technical details in these pages. Each of the covered packages gets nice documentation, complete with listings of configuration files and explicit statements of console input and output. --David Wall Topics covered: Packages designed to enable VPNs between Linux gateways. Software oriented toward standard protocols (PPP-over-SSH, PPP-over-SSL, IPsec, and PPTP) as well as nonstandard ones (VTun, cIPe, and tinc). Lots of coverage goes to FreeS/WAN and ppp-mppe.
