Book Description
Computer security is an ongoing process, a relentless contest between system administrators and intruders. A good administrator needs to stay one step ahead of any adversaries, which often involves a continuing process of education. If you're grounded in the basics of security, however, you won't necessarily want a complete treatise on the subject each time you pick up a book. Sometimes you want to get straight to the point. That's exactly what the new Linux Security Cookbook does. Rather than provide a total security solution for Linux computers, the authors present a series of easy-to-follow recipes--short, focused pieces of code that administrators can use to improve security and perform common tasks securely.The Linux Security Cookbook includes real solutions to a wide range of targeted problems, such as sending encrypted email within Emacs, restricting access to network services at particular times of day, firewalling a webserver, preventing IP spoofing, setting up key-based SSH authentication, and much more. With over 150 ready-to-use scripts and configuration files, this unique book helps administrators secure their systems without having to look up specific syntax. The book begins with recipes devised to establish a secure system, then moves on to secure day-to-day practices, and concludes with techniques to help your system stay secure.Some of the "recipes" you'll find in this book are: Controlling access to your system from firewalls down to individual services, using iptables, ipchains, xinetd, inetd, and more Monitoring your network with tcpdump, dsniff, netstat, and other tools Protecting network connections with Secure Shell (SSH) and stunnel Safeguarding email sessions with Secure Sockets Layer (SSL) Encrypting files and email messages with GnuPG Probing your own security with password crackers, nmap, and handy scripts This cookbook's proven techniques are derived from hard-won experience. Whether you're responsible for security on a home Linux system or for a large corporation, or somewhere in between, you'll find valuable, to-the-point, practical recipes for dealing with everyday security issues. This book is a system saver.

Book Description
Seven Deadliest Unified Communications Attacks provides a comprehensive coverage of the seven most dangerous hacks and exploits specific to Unified Communications (UC) and lays out the anatomy of these attacks including how to make your system more secure. You will discover the best ways to defend against these vicious hacks with step-by-step instruction and learn techniques to make your computer and network impenetrable. The book describes the intersection of the various communication technologies that make up UC, including Voice over IP (VoIP), instant message (IM), and other collaboration technologies. There are seven chapters that focus on the following: attacks against the UC ecosystem and UC endpoints; eavesdropping and modification attacks; control channel attacks; attacks on Session Initiation Protocol (SIP) trunks and public switched telephone network (PSTN) interconnection; attacks on identity; and attacks against distributed systems. Each chapter begins with an introduction to the threat along with some examples of the problem. This is followed by discussions of the anatomy, dangers, and future outlook of the threat as well as specific strategies on how to defend systems against the threat. The discussions of each threat are also organized around the themes of confidentiality, integrity, and availability. This book will be of interest to information security professionals of all levels as well as recreational hackers. - Knowledge is power, find out about the most dominant attacks currently waging war on computers and networks globally - Discover the best ways to defend against these vicious attacks; step-by-step instruction shows you how - Institute countermeasures, don't be caught defenseless again, and learn techniques to make your computer and network impenetrable

Book Description
This book will walk the reader through the process of preparing and deploying open source host integrity monitoring software, specifically, Osiris and Samhain. From the configuration and installation to maintenance, testing, and fine-tuning, this book will cover everything needed to correctly deploy a centralized host integrity monitoring solution. The domain includes home networks on up to large-scale enterprise environments.Throughout the book, realistic and practical configurations will be provided for common server and desktop platforms. By the end of the book, the reader will not only understand the strengths and limitations of host integrity tools, but also understand how to effectively make use of them in order to integrate them into a security policy.* Brian Wotring is the creator of Osiris. He speaks and writes frequently on Osiris for major magazines, Web sites, and trade shows. And, the book can be prominently marketed from the Osiris Web site* This is the first book published on host integrity monitoring, despite the widespread deployment of Osiris and Samhain* Host Integrity Monitoring is the only way to accurately determine if a malicious attacker has successfully compromised the security measures of your network

Book Description
From the authors of the bestselling E-Mail Virus Protection Handbook! The Linux operating system continues to gain market share based largely on its reputation as being the most secure operating system available. The challenge faced by system administrators installing Linux is that it is secure only if installed and configured properly, constantly and meticulously updated, and carefully integrated with a wide variety of Open Source security tools. The fact that Linux source code is readily available to every hacker means that system administrators must continually learn security and anti-hacker techniques. Hack Proofing Linux will provide system administrators with all of the techniques necessary to properly configure and maintain Linux systems and counter malicious attacks. Linux operating systems and Open Source security tools are incredibly powerful, complex, and notoriously under-documented - this book addresses a real need Uses forensics-based analysis to give the reader an insight to the mind of a hacker
