Which of the following denotes the confidentiality and integrity goals of an information security system?

The correct answer emphasizes the core principles of information security, namely confidentiality and integrity, while also encompassing other critical components that ensure a robust security framework.

Confidentiality refers to safeguarding information from unauthorized access, ensuring that sensitive information is only accessible to those who are authorized to view it. Integrity pertains to maintaining the accuracy and reliability of data, ensuring that it cannot be altered or tampered with by unauthorized users.

In addition to these two goals, the inclusion of availability acknowledges that information must be accessible to authorized users when needed. Authentication verifies the identity of users accessing the information, and non-repudiation provides assurance that a transaction or communication cannot be denied after it has occurred, supporting accountability.

This comprehensive view recognizes that a secure information system must not only protect against unauthorized access and data manipulation but also ensure that authorized users can access information when needed and that actions taken within the system are verifiable and accountable.

In contrast, the other options do not sufficiently cover the full spectrum of the confidentiality and integrity goals combined with the necessary surrounding principles of a security framework. They either focus on aspects that don't directly pertain to confidentiality and integrity or omit other essential components like availability or authentication that contribute to a holistic security posture.
