Mastering FreeBSD and OpenBSD Security by Yanek Korff,Paco Hope,Bruce Potter Pdf

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.

Secure Architectures with OpenBSD by Brandon Palmer,Jose Nazario Pdf

"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.

The Linux Command Line, 2nd Edition by William Shotts Pdf

You've experienced the shiny, point-and-click surface of your Linux computer--now dive below and explore its depths with the power of the command line. The Linux Command Line takes you from your very first terminal keystrokes to writing full programs in Bash, the most popular Linux shell (or command line). Along the way you'll learn the timeless skills handed down by generations of experienced, mouse-shunning gurus: file navigation, environment configuration, command chaining, pattern matching with regular expressions, and more. In addition to that practical knowledge, author William Shotts reveals the philosophy behind these tools and the rich heritage that your desktop Linux machine has inherited from Unix supercomputers of yore. As you make your way through the book's short, easily-digestible chapters, you'll learn how to: • Create and delete files, directories, and symlinks • Administer your system, including networking, package installation, and process management • Use standard input and output, redirection, and pipelines • Edit files with Vi, the world's most popular text editor • Write shell scripts to automate common or boring tasks • Slice and dice text files with cut, paste, grep, patch, and sed Once you overcome your initial "shell shock," you'll find that the command line is a natural and expressive way to communicate with your computer. Just don't be surprised if your mouse starts to gather dust.

The Practice of Network Security Monitoring by Richard Bejtlich Pdf

Network security is not simply about building impenetrable walls—determined attackers will eventually overcome traditional defenses. The most effective computer security strategies integrate network security monitoring (NSM): the collection and analysis of data to help you detect and respond to intrusions. In The Practice of Network Security Monitoring, Mandiant CSO Richard Bejtlich shows you how to use NSM to add a robust layer of protection around your networks—no prior experience required. To help you avoid costly and inflexible solutions, he teaches you how to deploy, build, and run an NSM operation using open source software and vendor-neutral tools. You'll learn how to: –Determine where to deploy NSM platforms, and size them for the monitored networks –Deploy stand-alone or distributed NSM installations –Use command line and graphical packet analysis tools, and NSM consoles –Interpret network evidence from server-side and client-side intrusions –Integrate threat intelligence into NSM software to identify sophisticated adversaries There’s no foolproof way to keep attackers out of your network. But when they get in, you’ll be prepared. The Practice of Network Security Monitoring will show you how to build a security net to detect, contain, and control them. Attacks are inevitable, but losing sensitive data shouldn't be.
