When thinking about security, most people start by thinking about their stuff. We all have stuff. We have stuff that we really care about, we have stuff that would be really difficult to replace, and we have stuff that has great sentimental value. We have stuff we really don’t want other people to find out about. We even have stuff that we could probably live without. Now think about where you keep your stuff. It could be in your house, your car, your school, your office, in a locker, in a backpack or a suitcase, or a number of other places. Lastly, think about all of the dangers that could happen to your stuff. People could be robbed or experience a disaster such as a fire, earthquake, or flood. In any case, we all want to protect our possessions no matter where the threat comes from.
