Linux Security: Easy as 1-2-3

"Linux is a secure OS."

You've probably heard this statement from time to time, and compared to Windows you could argue that it is. But really it's kind of a meaningless statement: no system which is connected to a network or used by human beings is completely secure, and if it was it would probably be useless.

But you can certainly beef up the security of a given Linux system to make it more secure than it would otherwise be - while still enabling it to do its job - and it's that process, known as hardening, that is the subject of this article. Without going in to the finer details, we'll be looking at the general steps you should take to harden any system under your control that warrants extra security beyond what you believe is necessary for your "normal" systems.

Before you can start the process of hardening a given system you need to have a clear idea of what they system is to be used for, what software it will therefore need to run, and the sorts of threats or vulnerabilities you want to protect against.
