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.

Presently, Linux is free from Torjans, Viruses etc., for the most part. However, when the number of Linux users goesup dramatically, I feel this might not be the case anymore. Those who propagate all these infections have their own reasons and will find a way to infect PCs running Linux. Comments/opinions welcome.
Linux is fundamentally diffrent in the way it executes programs, Making it very hard for a user to damage the system (can't right to almost any Folder unless your root) Which makes Virii very difficult to write as they can't get at anything to do damage. (They could wipe your home directory thats about it.)
Also we don't have VB and scripting in Mail (I suugest the first mail program that does this, its maintainers are put against a wall and shot.)
Their are exploits, but even the most exotic are cured before anyone knre they existed, and security is tight and then relaxed as necessary in Linux (usually) Not the Windows way of everthing Open then closed.
Just my £0.02 worth. (which of course worth more than $0.02 )
This is not that great come to think of it. So basically, what happens here then is that evverything I worked on is lost. However, the free Linux for which I have a installation CD remains safe ? Not a pleasant situation to be in if it were to ever happen.
Losing any information isn't pleasant. But If you can keep the os secure and most of the mods in it then you have won half the battle. Sure you have cd's for most and probably (if smart) have drivers burned too, but, what about all the time it takes to set it up? I would be much happier losing my docs, then losing my OS. Anyways a smart person keeps a backup of sensitive data like that.
It takes alot more skill/knowledge to write naughty software for Unix/Linux, but it can be done - however - Unix/Linux on the whole tends to be inherently more secure than Windows because of its nature.
I disagree with most of what is said here. The home directory is extremely vulnerable, and is the most important part of the system. Also, it's possible to write viruses and worms which do not require root access.
Basically, I've seen no strong arguments that Linux is any more secure than any other OS out there. I've seen too many ways in which a Linux box can be utterly screwed through and through by the simplest of programs to believe that for long.
The best approach to solving this problem IMHO is to have a community dedicated to wargaming, where people attempt to figure out ways to get malicious software onto systems and those holes are patched up quickly - and more important, when viruses/worms or spyware does start spreading, we have effective anti-virus and update mechanisms in place to ensure we can neutralise it quickly.
Basically what Linux needs is a community-driven equivalent to McAffee or Sophos. I doubt we'll see such a thing arise until Linux becomes a target however.
Those who develop Spyware, Adware, Trojans, Viruse etc., etc., have their own special reasons and motives. They are always learning, improving and developing. So the competition between the user and those who infect is an ongoing one. With more security, patches they will figure new and better ways to infect. Wait till Linux becomes popular and there is a lot lesser Windows users. When the Linux systems are still running during a major infection, the other side will know that they need a new approach and get one very fast.
