Secure your Apache server from DDoS, Slowloris, and DNS Injection attacks

Apache is the most widely used web server on the planet, and it's also one of the most widely attacked. To that end, it's always smart to lock down your Apache server as best as possible. This goes well beyond just locking down your network -- you need to give that Apache server as much attention as it might get from outside sources.

I'll walk you through the process of preventing your Apache server from Distributed Denial of Service (DDoS), Slowloris, and DNS Injection attacks. These breakins are quite simple to prevent, as long as you take the time to lock down that server.

I'm assuming that your Apache server is up and running and (for simplicity's sake) that it's running on the Ubuntu platform -- for any other platform, you'll need to make minor adjustments. All of this work will be done from within a console window, so prepare to get "the flavor of console" all over your fingertips.
