Protecting Mission-Critical Systems

Albert Caballero,    Terremark Worldwide, Inc.

Information security involves the protection of organizational assets from the disruption of business operations, modification of sensitive data, or disclosure of proprietary information. The protection of this data is usually described as maintaining the confidentiality, integrity, and availability (CIA) of the organization’s assets, operations, and information. As identified throughout this chapter, security goes beyond technical controls and encompasses people, technology, policy, and operations in a way that few other business objectives do.
