Which option is primarily focused on protecting data from unauthorized access?

• A. Integrity
• B. Availability
• C. Confidentiality
• D. Non-repudiation

Answer: (C)

The focus of the option related to protecting data from unauthorized access is confidentiality. Confidentiality ensures that sensitive information is accessed only by those who are authorized to view it. This principle is fundamental to data security as it safeguards personal information, intellectual property, and any other sensitive data from unauthorized disclosure. To maintain confidentiality, various security measures are implemented, including encryption, access controls, and authentication mechanisms. These strategies help prevent unwanted access to information, thereby protecting against data breaches and unauthorized information disclosure. In contrast, integrity pertains to the accuracy and consistency of data, ensuring it remains unaltered during processing or storage by unauthorized individuals. Availability refers to ensuring that authorized users have timely and reliable access to data and systems. Non-repudiation involves ensuring that a party cannot deny the authenticity of their signature or the sending of a message, providing proof of origin, and accountability but does not directly address data access. Therefore, confidentiality is specifically aligned with the goal of preventing unauthorized access to data.
