Security is therefore the process of ensuring our safety; responsible for maintaining the safeguards we expect will always be in place. In order for security to be effective, the components of how our safety is defined need to remain unchanged.
Like the temperature in your home, security is the thermostat making sure your settings stay constant. This also means that the failures of security mostly result from the parameters of safety being improperly managed. The inside of your home is easy to keep a cozy room temperature, but the outside world is not so easily controlled.
