Information assurance and security is the management and protection of knowledge, information, and data. It combines two fields:
– Information assurance, which focuses on ensuring the availability, integrity, authentication, confidentiality, and non-repudiation of information and systems. These measures may include providing for restoration of information systems by incorporating protection, detection, and reaction capabilities.
– Information security management, which centers on the protection of information and information systems from unauthorized access, use, disclosure, disruption, modification, or destruction in order to provide confidentiality, integrity, and availability.
