What does security ensure in terms of information management?

In information management, security plays a critical role in safeguarding data from unauthorized access and ensuring its reliability. The correct choice focuses on three key aspects: confidentiality, integrity, and user authentication.

Confidentiality ensures that sensitive information is only accessible to those who have legitimate access rights. This means that the information is protected from unauthorized users. Integrity, on the other hand, guarantees that the data remains accurate and unaltered during storage and transmission. This is crucial for maintaining trust in the information being used for decision-making. Lastly, user authentication verifies the identity of individuals accessing the information, thereby providing an additional layer of protection against unauthorized access or data breaches.

Together, these components create a robust security framework that helps organizations manage their information safely and effectively. It is essential for maintaining compliance with various regulations and protecting the organization's reputation and assets.

Other choices focus on different aspects of information management that, while important, do not directly relate to the fundamental security goals of confidentiality, integrity, and authentication. For instance, fast access to data, reduced operational costs, and ease of data transfer, while valuable for efficiency and performance, do not address the critical protective measures that security provides.
