Measures that protect and defend information and information systems by ensuring their availability integrity authentication confidentiality and non-repudiation?

Measures that protect and defend information and information systems include various security protocols and practices designed to ensure key elements such as availability, integrity, authentication, confidentiality, and non-repudiation. Availability ensures that information and systems are accessible when needed, while integrity guarantees that the data remains accurate and unaltered. Authentication verifies the identities of users and systems, and confidentiality protects sensitive information from unauthorized access. Non-repudiation ensures that actions taken by users can be verified and cannot be denied, establishing accountability within the system.
