Available in PDF, EPUB and Kindle. Book excerpt: "This book works in tandem with the OpenBSD's manual pages. As a result, it will help many users grow and get the most from the system."--Theo de Raadt, OpenBSD project leader. "The OpenBSD system intimidates many administrators who would benefit from using it. This book lets people start much higher up on the curve. Secure Architectures with OpenBSD not only presents the hows, but also shows some of the whys that only insiders know."--Mike Frantzen, NFR Security "Secure Architectures with OpenBSD explains all of the tasks an administrator has to know about to successfully maintain an OpenBSD server. It helps the reader save time by condensing the vast amount of information available in man pages into a compact form, reducing unneeded information, and explaining other things in much more detail and prose than a man page can afford."--Daniel Hartmeier, the OpenBSD Project "This book will become the de facto text for OpenBSD administration. Unix and BSD books abound, but none cover OpenBSD with the clarity and expertise of Palmer and Nazario. They explain the optimal way to configure and administer your OpenBSD machines, with a keen eye to security at all stages."--Brian Hatch, coauthor of Hacking Exposed Linux and Building Linux Virtual Private Networks Descended from BSD, OpenBSD is a popular choice for those who demand stability and security from their operating system. No code goes into OpenBSD without first undergoing a rigorous security check, making it a terrific choice for Web servers, VPNs, and firewalls. Secure Architectures with OpenBSD is the insider's guide to building secure systems using OpenBSD. Written by Brandon Palmer and Jose Nazario, this book is a how-to for system and network administrators who need to move to a more secure operating system and a reference for seasoned OpenBSD users who want to fully exploit every feature of the system. After getting readers started with OpenBSD, the authors explain system configuration and administration, then explore more exotic hardware and advanced topics. Every chapter of the book addresses the issue of security because security is integrated into almost every facet of OpenBSD. Examples appear throughout the book, and the authors provide source code and system details unavailable anywhere else. This goes well beyond the basics and gives readers information they will need long after they have installed the system. Key topic coverage includes: Installation and upgrade details Basic system usage in OpenBSD versus other Unix systems Third-party software via packages and the ports tree SMTP services in OpenBSD Web services with Apache Using OpenBSD as a firewall OpenBSD as a Kerberos V client and server Use of Ipsec Configuration and use of IPv6 Network intrusion detection Secure Architectures with OpenBSD takes you inside OpenBSD, giving you the insights and expertise no system manual can provide. The companion Web site tracks advances and changes made to the operating system, and it contains updates to the book and working code samples.

Available in PDF, EPUB and Kindle. Book excerpt: FreeBSD and OpenBSD are increasingly gaining traction in educational institutions, non-profits, and corporations worldwide because they provide significant security advantages over Linux. Although a lot can be said for the robustness, clean organization, and stability of the BSD operating systems, security is one of the main reasons system administrators use these two platforms.There are plenty of books to help you get a FreeBSD or OpenBSD system off the ground, and all of them touch on security to some extent, usually dedicating a chapter to the subject. But, as security is commonly named as the key concern for today's system administrators, a single chapter on the subject can't provide the depth of information you need to keep your systems secure.FreeBSD and OpenBSD are rife with security "building blocks" that you can put to use, and Mastering FreeBSD and OpenBSD Security shows you how. Both operating systems have kernel options and filesystem features that go well beyond traditional Unix permissions and controls. This power and flexibility is valuable, but the colossal range of possibilities need to be tackled one step at a time. This book walks you through the installation of a hardened operating system, the installation and configuration of critical services, and ongoing maintenance of your FreeBSD and OpenBSD systems.Using an application-specific approach that builds on your existing knowledge, the book provides sound technical information on FreeBSD and Open-BSD security with plenty of real-world examples to help you configure and deploy a secure system. By imparting a solid technical foundation as well as practical know-how, it enables administrators to push their server's security to the next level. Even administrators in other environments--like Linux and Solaris--can find useful paradigms to emulate.Written by security professionals with two decades of operating system experience, Mastering FreeBSD and OpenBSD Security features broad and deep explanations of how how to secure your most critical systems. Where other books on BSD systems help you achieve functionality, this book will help you more thoroughly secure your deployments.

Available in PDF, EPUB and Kindle. Book excerpt: Over the years, thousands of tools have been developed for debugging TCP/IP networks. They range from very specialized tools that do one particular task, to generalized suites that do just about everything except replace bad Ethernet cables. Even better, many of them are absolutely free. There's only one problem: who has time to track them all down, sort through them for the best ones for a particular purpose, or figure out how to use them?Network Troubleshooting Tools does the work for you--by describing the best of the freely available tools for debugging and troubleshooting. You can start with a lesser-known version of ping that diagnoses connectivity problems, or take on a much more comprehensive program like MRTG for graphing traffic through network interfaces. There's tkined for mapping and automatically monitoring networks, and Ethereal for capturing packets and debugging low-level problems.This book isn't just about the tools available for troubleshooting common network problems. It also outlines a systematic approach to network troubleshooting: how to document your network so you know how it behaves under normal conditions, and how to think about problems when they arise, so you can solve them more effectively.The topics covered in this book include: Understanding your network Connectivity testing Evaluating the path between two network nodes Tools for capturing packets Tools for network discovery and mapping Tools for working with SNMP Performance monitoring Testing application layer protocols Software sources If you're involved with network operations, this book will save you time, money, and needless experimentation.

Book excerpt: While Mac OS X is becoming more and more stable with each release, its UNIX/BSD underpinnings have security implications that ordinary Mac users have never before been faced with. Mac OS X can be used as both a powerful Internet server, or, in the wrong hands, a very powerful attack launch point. Yet most Mac OS X books are generally quite simplistic -- with the exception of the author's "Mac OS X Unleashed," the first book to address OS X's underlying BSD subsystem. "Maximum Mac OS X Security" takes a similar UNIX-oriented approach, going into significantly greater depth on OS X security topics: Setup basics, including Airport and network topology security. User administration and resource management with NetInfo. Types of attacks, how attacks work, and how to stop them. Network service security, such as e-mail, Web, and file sharing. Intrusion prevention and detection, and hands-on detection tools.

Book excerpt: We live in a wired society, with computers containing and passing around vital information on both personal and public matters. Keeping this data safe is of paramount concern to all. Yet, not a day seems able to pass without some new threat to our computers. Unfortunately, the march of technology has given us the benefits of computers and electronic tools, while also opening us to unforeseen dangers. Identity theft, electronic spying, and the like are now standard worries. In the effort to defend both personal privacy and crucial databases, computer security has become a key industry. A vast array of companies devoted to defending computers from hackers and viruses have cropped up. Research and academic institutions devote a considerable amount of time and effort to the study of information systems and computer security. Anyone with access to a computer needs to be aware of the developing trends and growth of computer security. To that end, this book presents a comprehensive and carefully selected bibliography of the literature most relevant to understanding computer security. Following the bibliography section, continued access is provided via author, title, and subject indexes. With such a format, this book serves as an important guide and reference tool in the defence of our computerised culture.
