Maximum Linux Security: A Hacker’s Guide to Protecting Your Linux Server and Workstation is designed for system administrators, managers, or Linux users who wish to protect their Linux servers and workstations from unauthorized intrusions and other external threats to their systems’ integrity. Written by an experienced hacker–someone who knows which systems are vulnerable and how crackers get into them–this unique guide to Linux security identifies existing and potential security holes and faults, and then describes how to go about fixing them.

This comprehensive guide can help you administer Red Hat Enterprise Linux 5 effectively in any production environment, no matter how complex or challenging.

Long-time Red Hat insider Tammy Fox brings together today’s best practices for the entire system lifecycle, from planning and deployment through maintenance and troubleshooting. Fox shows how to maximize your efficiency and effectiveness by automating day-to-day maintenance through scripting, deploying security updates via Red Hat Network, implementing central identity management services, and providing shared data with NFS and Samba.

Red Hat Enterprise Linux 5 Administration Unleashed contains extensive coverage of network and web services, from the Apache HTTP server and Sendmail email services to remote login with OpenSSH. Fox also describes Red Hat’s most valuable tools for monitoring and optimization and presents thorough coverage of security including a detailed introduction to Security-Enhanced Linux (SELinux).

* Streamline deployment with Kickstart.
* Find, install, update, remove, and verify software.
* Detect, analyze, and manage hardware.
* Manage storage with LVM, RAID, ACLs, and quotas.
* Use Red Hat Enterprise Linux 5 on 64-bit and multi-core systems.
* Administer users and groups more efficiently and securely.
* Ensure trustworthy backup and rapid recovery.
* Script and schedule tasks to run automatically.
* Provide unified identity management services.
* Configure Apache, BIND, Samba, and Sendmail.
* Monitor and tune the kernel and individual applications.
* Protect against intruders with SELinux and ExecShield.
* Set up firewalls with iptables.
* Enable the Linux Auditing System.
* Use virtualization to run multiple operating systems concurrently.

This practical guide teaches you how to implement effective network protection by using your own customized firewall solution. Based on extensive practical experience, this book distills a unique set of scenario based scripts and guidelines for a proven firewall solution, into one succinct and precise book. This book shows you how to implement Linux firewalls and Quality of Service using practical examples from very small to very large networks.

After giving us a background of network security, the book moves on to explain the basic technologies we will work with, namely netfilter, iproute2, NAT and l7-filter. These form the crux of building Linux firewalls and QOS.Providing only necessary theoretical background, the book takes a practical approach, presenting case studies and plenty of illustrative examples.

Concentrating on Linux installation, tuning, and administration, this guide to protecting systems from security attacks demonstrates how to install Linux so that it is tuned for the highest security and best performance, how to scan the network and encrypt the traffic for securing all private traffics in a public network, and how to monitor and log the system to detect potential security problems. Backup and recovery policies that provide a structure for secure operations are also considered, and information related to configuring an Apache server, e-mail service, and the Internet gateway using a proxy server, an FTP server, DNS server for mapping DNS names to IP addresses, and firewall for system protection is provided.

LINUX For You is the latest publication from the EFY Group. This magazine caters to newbies, power-users, administrators, developers and those belonging to the IT industry. It’s main goal is to enhance the return on investment (RoI) for organisations by deploying Linux (or open-source) solutions.

Product Description

This unique and valuable collection of tips, tools, and scripts provides clear, concise, hands-on solutions that can be applied to the challenges facing anyone running a network of Linux servers from small networks to large data centers in the practical and popular problem-solution-discussion O’Reilly cookbook format.

The Linux Cookbook covers everything you’d expect: backups, new users, and the like. But it also covers the non-obvious information that is often ignored in other books the time-sinks and headaches that are a real part of an administrator’s job, such as: dealing with odd kinds of devices that Linux historically hasn’t supported well, building multi-boot systems, and handling things like video and audio. The knowledge needed to install, deploy, and maintain Linux is not easily found, and no Linux distribution gets it just right. Scattered information can be found in a pile of man pages, texinfo files, and source code comments, but the best source of information is the experts themselves who built up a working knowledge of managing Linux systems. This cookbook’s proven techniques distill years of hard-won experience into practical cut-and-paste solutions to everyday Linux dilemmas. Use just one recipe from this varied collection of real-world solutions, and the hours of tedious trial-and-error saved will more than pay for the cost of the book. But those who prefer to learn hands-on will find that this cookbook not only solves immediate problems quickly, it also cuts right to the chase pointing out potential pitfalls and illustrating tested practices that can be applied to a myriad of other situations. Whether you’re responsible for a small Linux system, a huge corporate system, or a mixed Linux/Windows/MacOS network, you’ll find valuable, to-the-point, practical recipes for dealing with Linux systems everyday. The Linux Cookbook is more than a time-saver; it’s a sanity saver.

About the Author
Carla Schroder is a freelance system administrator and technical writer, who has written for IBM Developerworks, Intel, Crossnodes.com, and Computerbits.com.

Written by an experienced Linux thin client network designer and implementer, this book walks you through the concepts of thin client networks, and design issues associated with implementations of various sizes, setting up the framework, outlining strategies, principles, and best practice for creating the design, before leading you through the implementation step by step.

A thin client network is a client-server architecture where client computers depend primarily on a central server for processing activities. The client machines (thin clients) mainly focus on passing user input to remote services and receiving and displaying the output; thin clients aren’t as much about the hardware or software as about the design.

This book has all the information you need to easily set up your own Linux thin client network. It will help you evaluate how a thin client network fits into your organization and make informed choices on the hardware and software needed for your deployment, discusses design issues, and guides you with building, configuring, and supporting the network.

The author has given thought to the book to create something that is well rounded, and meets the needs of small and large organizations.

Linux is known as a secure environment and a good platform to run a web server

. These topics are among the many covered in this book. But did you know you can also burn CDs, sync a PalmPilot™, and edit slideshow presentations with powerful tools on Linux? Those topics are covered here, too. Red Hat currently provides two distributions, both documented in this book. The first is their commercial, subscription-based product, called Red Hat Enterprise Linux and also available through retail channels as Red Hat Professional Workstation. The second is the freely distributed Fedora distribution. The Publisher’s Edition of Fedora is included in this book on two disks. New in this edition are installation instructions for Red Hat Enterprise Linux and Fedora, package updating for Red Hat Enterprise Linux and Fedora, information on the GRUB bootloader, and the CUPS printer system.
