information assurance (IA)
Information Assurance (IA) is used to secure and protect electronic information.
Information assurance includes access control, vulnerability assessment, threat detection, and recovery procedures for system functionality and content after attacks and crashes.
The Department of Defense Instruction (DoDI) has defined information assurance as "all measures that protect and defend information and information systems by ensuring their availability, integrity, authentication, confidentiality, and non-repudiation."
