Describe the technologies and strategies that you would employ in
order to protect and secure your Web site.

This isn't as easy as you might think. Before you plan certain
strategies how to secure your website, you have to ask you a few
questions:
1. Am I able to secure the website by myself or should I employ
someone who knows what he is doing? Securing requires very good
knowledge of the Internet Protocol and your system.
2. What am I afraid of? (defacing, hacking...)
3. Where is your website hosted? at home, at an ISP? Offers the ISP
such a service? Is it a Windows or a UNIX system? What software have
to run on this software? (less software, more security)
Beside this and other considerations, you should start reading and
learn about security.
