Security, Privacy, Performance, and Reliability Issues

It might seem a bit strange to place the four topics in the heading for this section together, but you really do need to consider them as a group. Changing one item normally affects the other three in a negative way. For example, when you increase privacy, you decrease what you know about those visiting your Web site. As a result, your ability to search for potential security flaws decreases. Enhancing privacy also means using more system resources, so performance takes a hit. Finally, adding more processing to your system increases the number of failure points, which decreases reliability. In short, you can’t make one change without changing your entire setup.
