Which of the following are the three security objectives for information and information systems?

The three security objectives for information and information systems are often summarized as confidentiality, integrity, and availability, commonly referred to as the CIA triad.

Confidentiality ensures that sensitive information is accessed only by authorized individuals, protecting it from unauthorized disclosure. Integrity involves maintaining the accuracy and completeness of data, ensuring that information is reliable and has not been altered in an unauthorized manner. Availability ensures that information and resources are accessible to authorized users when needed, maintaining system uptime and functionality.

These three principles are foundational to information security practices, guiding organizations in creating effective policies, controls, and measures to protect their data and systems from various threats. The other choices incorporate terms related to information security, such as authentication, compliance, and accountability, but do not encompass the core objectives as succinctly or effectively as the first option.
