Cybersecurity Glossary: Information Assurance and Security Management

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.
