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

A guide to using the Ghidra software reverse engineering tool suite. The result of more than a decade of research and development within the NSA, the Ghidra platform was developed to address some of the agency's most challenging reverse-engineering problems.

In addition to discussing RE techniques useful in analyzing software and malware of all kinds, the book thoroughly introduces Ghidra's components, features, and unique capacity for group collaboration. You'll learn how to: Navigate a disassembly Use Ghidra's built-in decompiler to expedite analysis Analyze obfuscated binaries Extend Ghidra to recognize new data types Build new Ghidra analyzers and loaders Add support for new processors and instruction sets Script Ghidra tasks to automate workflows Set up and use a collaborative reverse engineering environment Designed for beginner and advanced users alike, The Ghidra Book will effectively prepare you to meet the needs and challenges of RE, so you can analyze files like a pro.

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.

A unique, practical resource goes beyond the "how to install Linux" books to detail ways that people and businesses can solve real-world problems with free, open source software. The authors present a series of real-world business computing situations, both for the home and business user, and then tell what Linux and free software provides to solve the problem.
