In general, security is “the quality or state of being secure—to be free from danger.”11 In
other words, protection against adversaries—from those who would do harm, intentionally
or otherwise—is the objective. National security, for example, is a multilayered system that
protects the sovereignty of a state, its assets, its resources, and its people. Achieving the appropriate level of security for an organization also requires a multifaceted system.
