Security -- simply mentioning the word to some people is enough to make their bodies shiver.  If you ask these people at what point in their process is security involved, most will answer "not until the end."  Remember the old addage, "closing the barn door after the horse escapes?"  There are others of course that would work here but you get the point. Don't wait until the end to think about security.
