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. Also, they use phishing scams and spyware in order to steal our personal information (including passwords), which they can then use to access our computer systems and even steal our identities.
