Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

They are all open source... lockdown may take a little practice/trial and error, I suggest you build a test host specifically for this. Let me know once you have a test machine and I'll provide some of the hardening from kickstart scripts that I use. You will need to test very thoroughly after locking down to ensure that everything works as expected
The locking happens with Fedora 11 by default. I am using GNOME. And as we are connecting to citrix servers (Windows servers we will access from the citrix) , i feel no need lock the local machine.
Local machine is not in any domain, instead it will receive only IPs and we connect to the citrix servers. So, if a local machine is unlocked also nothing much is lost as far as the data is concerned and security.
What I am now concerned is reducing the boottime and Hardening the system. I have not really gone to the internal of the system yet,
But please help me with the hardening
Thanks again for your support, it gives me lot of motivation go further.
I'd like to point out that Fedora is Redhat's R&D distro, with a new version every 13 mths and only the current and prev versions supported. It's a bit bleeding edge.
For long term support/stability (especially for a business env) try Centos (free version of RHEL).
The seven year life cycle for a major release of Red Hat Enterprise Linux is divided into three phases.
Our company is going down the same path as you. Any chance that we can compare notes. One of the problems that I'm having is with Citrix understanding the many different usb drives that might be put in the host machine.
