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.

I have installed RH 9 recently. After installation I have done nothing but configured squid. For last three months it's sitting there running squid for a cache proxy.
As I read on this website that RH9 is not supported anymore. I don't wanna go for another distribution or installation. Am I at risk? Is my system vulnerable to different threats? Viruses? Hackers?
If it, which of the distribution is most similar to RedHat? Can I migrate without re-installation?
No need to change distributions or upgrade to the latest version. You just need to backup your squid's config files then uninstall squid. Next compile the latest squid version. Copy the backup squid configs files to the squid directory. Usually its in /etc.
You should apply all the relevant RH 9 security patches, plus all ofthe ones from the fedora legacy project. The Fedora Legacy project is still releasing security packages for RH 9, so if you keep up to date with those, you're pretty well solid. You can also compile updated software from source, as Electro suggested, which is helpfull since Fedora legacy sometimes seems a bit slow at putting patches out.
As I mentioned that my Linux is only serving as a proxy nothing else. I do see a lot of service being started when booting. Which service should I let start and which ones should I stop to make my system less vulnerable?
