    This article explains the steps I take to secure my home computer and data communications. If you are an active proponent of computer security, this article will be a review. If you do not have any security practices currently, you should read on to get a general idea of how to secure a Linux box. This obviously isn't a complete security reference - I take security seriously, but I'm not as vigilant as I could be with my computer. You will have to see for yourself whether or not the items in this article provide enough security for your needs. . . .

    I run a Debian Linux box here at home. I keep it powered up and connected to the Internet at all times. There are two reasons I want to keep this computer secure - to hide my data from those who shouldn't see it, and to protect my computer resources from those who shouldn't be using them. I keep important stuff on my machine - data that shouldn't be read (and certainly not modified) by anyone but me. And I don't want an intruder to be able to use my machine as a staging ground for attacks on other targets. I'd be pretty pissed if I found out someone was using my machine to try to break into other systems.
