Security is about protecting assets, such as money and physical possessions. For instance, we use walls, locks, burglar alarms, and even armed guards to keep other people from stealing and/or destroying our stuff. These days, information is typically one of our most important assets. Thus, we have to worry about the possibility of other people stealing and/or destroying it. For instance, criminals threaten our data with scareware or ransomware in order to extort money from us.
