Information assurance (nonfiction)

Information assurance (IA) is the practice of assuring information and managing risks related to the use, processing, storage, and transmission of information or data and the systems and processes used for those purposes. Information assurance includes protection of the integrity, availability, authenticity, non-repudiation and confidentiality of user data.[1] It uses physical, technical, and administrative controls to accomplish these tasks. While focused predominantly on information in digital form, the full range of IA encompasses not only digital, but also analog or physical form. These protections apply to data in transit, both physical and electronic forms, as well as data at rest in various types of physical and electronic storage facilities. IA is best thought of as a superset of information security (i.e. umbrella term), and as the business outcome of information risk management.
