Information Assurance (IA) is the practice of managing information-related risks and the steps involved to protect information systems such as computer and network systems. The IA transformation is a partnership that stretches across the Department of Defense (DoD), Office of National Intelligence, Committee on National Security Systems, National Institute of Science and Technology (NIST), and the Office of Management and Budget.
The US Government's definition of information assurance is:
"measures that protect and defend information and information systems by ensuring their availability, integrity, authentication, confidentiality, and non-repudiation. These measures include providing for restoration of information systems by incorporating protection, detection, and reaction capabilities." Reference:
