Where can I send feedback about an Early Access title?

If you have any feedback about the product you're reading, or Early Access in general, then please fill out a contact form here and we'll make sure the feedback gets to the right team.

Can I download the code files for Early Access titles?

We try to ensure that all books in Early Access have code available to use, download, and fork on GitHub. This helps us be more agile in the development of the book, and helps keep the often changing code base of new versions and new technologies as up to date as possible. Unfortunately, however, there will be rare cases when it is not possible for us to have downloadable code samples available until publication.

When we publish the book, the code files will also be available to download from the Packt website.

How accurate is the publication date?

The publication date is as accurate as we can be at any point in the project. Unfortunately, delays can happen. Often those delays are out of our control, such as changes to the technology code base or delays in the tech release. We do our best to give you an accurate estimate of the publication date at any given time, and as more chapters are delivered, the more accurate the delivery date will become.

How will I know when new chapters are ready?

We'll let you know every time there has been an update to a course that you've bought in Early Access. You'll get an email to let you know there has been a new chapter, or a change to a previous chapter. The new chapters are automatically added to your account, so you can also check back there any time you're ready and download or read them online.

I am a Packt subscriber, do I get Early Access?

Yes, all Early Access content is fully available through your subscription. You will need to have a paid for or active trial subscription in order to access all titles.

How is Early Access delivered?

Early Access is currently only available as a PDF or through our online reader. As we make changes or add new chapters, the files in your Packt account will be updated so you can download them again or view them online immediately.

What is Early Access?

Keeping up to date with the latest technology is difficult; new versions, new frameworks, new techniques. This feature gives you a head-start to our content, as it's being created. With Early Access you'll receive each chapter as it's written, and get regular updates throughout the product's development, as well as the final course as soon as it's ready.We created Early Access as a means of giving you the information you need, as soon as it's available. As we go through the process of developing a course, 99% of it can be ready but we can't publish until that last 1% falls in to place. Early Access helps to unlock the potential of our content early, to help you start your learning when you need it most. You not only get access to every chapter as it's delivered, edited, and updated, but you'll also get the finalized, DRM-free product to download in any format you want when it's published. As a member of Packt, you'll also be eligible for our exclusive offers, including a free course every day, and discounts on new and popular titles.

I have been using Fedora Linux for years now. And the first thing that I've always done is disable SELinux. Thanks to this book, I am now running Fedora "properly" with SELinux in full enforcement mode with no problems. The book explained what was going on and how to address the various problems that I had been having. Excellent!

For a long time I avoided SELinux. It was too complicated and too poorly documented; so I just disabled it on my computers. Yet, I was always uncomfortable that I was leaving my systems open to being hacked. Along comes the "SELinux Cookbook", and I finally have enough info to use SELinux effectively. The book covers a number of topics: First, it helps set up some tools for building SELinux modules as well as examining the default configuration provided by the Operating System. It then goes on to provide techniques for securing Web servers, applications, and entire server systems. It has an excellent chapter on debugging SELinux problems that helped me determine if SELinux was actually at fault. (In some cases, other subsystems like firewalls might be at fault - you need to determine that before wasting time looking in the wrong place for a problem).One thing I particularly like about this book is that it clearly states the "why" behind the various examples. Too often, a book will say "do this" and leave me wondering "why? " That is not the case here - the author always explains how to do something , and then follows up with a justification for the given solution. In many of the examples, there is additional information describing limitations within SELinux. That is a big help; there is no point to trying to make the tools do something they cannot do.Altogether I am happy to have found this book. Any time I can learn something new, it is a good day. :-)

What it is SE Linux ?, the main meaning of SE Linux is (extracted from Wikipedia) : “ is a Linux kernel security module that provides a mechanism for supporting access control security policies. SELinux is a set of kernel modifications and user-space tools that have been added to various Linux distributions. Its architecture strives to separate enforcement of security decisions from the security policy itself and streamlines the volume of software charged with security policy enforcement.”So it is clear that SE Linux is not a linux distribution but it is a kernel module that provides mechanism over access of linux security policies. Now Packt Publishing is offering a new cookbook based on SE Linux for those experienced Linux system administrators and security administrators who wants to improve their knowledge or how to add more security for their linux systems and server.However the book is written based on Gentoo Linux (which is not really important, because this book is independent of linux distritbutions). The book focus on the structure and the reusable policy inside SE Linux and you will be able to create your first set of SE Linux module policy that will be integrated with the existing SELinux policies.The main topics of the book are (this are the chapters of the book):Get knowledge SE Linux Development Environment.Working with File Labels.Connifing Web Applications.Creating Server Policies.Setting up Separate Roles.Choosing theConnifing Levels.Debugging SELinux.Alligning SELinux with DAC.Handling SELinux-Aware Applications.One important point of view, you should have experience in Linux system administration, SELinux policy development and integration that requires good knowledge of the components how to confine and protect. You should have experience with Git version control system as an end user and also basic knowledge of how SELinux works on a system.A real practical book for those who wants to have deep experience on SE Linux system and how to add more secure policies in your linux servers!.

This is a great place to start if you don't know anything about SELinux. I must confess that although I have used Linux since the days when you had to boot it from a floppy disk, I have very little experience with SELinux, however. SELinux has always been kind of mysterious for me. No more after reading this book.

This book provides a simple(relative to SElinux) rulebook to create and evaluate SElinux rulesets so that you can harden or evaluate your linux server security. If you never touched SElinux before, chances are that you will find that book complex beyond reason, keep some references/documentation within reach and, more importantly, try "breaking stuff" with some test VMs so you will understand what you are typing/executing(don't do it on a production server as borked SElinux rules can and will bring it down hard :)).
