What core concept relates to 'breaching confidentiality'?

The concept of 'breaching confidentiality' is fundamentally linked to unauthorized access to sensitive information. When confidentiality is breached, it means that an individual or entity has gained access to information that is intended to be kept private or protected. This unauthorized access can lead to a variety of negative consequences, including financial loss, reputational damage, and potential legal ramifications.

In the context of information security, confidentiality ensures that sensitive data is only accessible to those who have the right to see it. A breach of this confidentiality disrupts this principle, thus revealing potentially harmful information to those who should not have knowledge of it. This is why unauthorized access is directly associated with breaches of confidentiality.

The other choices do not directly relate to the concept of breaching confidentiality. Loss of physical assets pertains more to property security than to the protection of information. A decrease in staff morale can be a consequence of various organizational issues, but it does not specifically connect to the breach of confidentiality. Reduction in data redundancy relates to data management practices and does not pertain to the unauthorized access or disclosure of confidential information.
