Discuss Defense in Depth. Provide different tactical concepts that apply to information technology. Again, even though these are focused on security, each applies to IT. While you need to be familiar with all of them, for this assignment you should choose one to explain in your own words. Include an example that explains the concept. Justify why the principle is important for IT Strategy and Tactics. Find at least one additional reference for each one you choose. Rather than providing a paper, you are to create a PowerPoint presentation explaining the concept. It should contain 10-15 slides, including a title slide and a reference slide. You may include pictures, graphs, figures, or charts to help your discussion of the topic. Your final presentation product should be professional in format as if you are going to present it to upper management. Make sure to include your name, class number, and assignment number in your PowerPoint Title slide and give proper attention to formatting, spelling, grammar, and punctuation.
