Define "confidentiality" in the context of DSAC Annex B.

Confidentiality, in the context of DSAC Annex B, refers to the assurance that sensitive and classified information is not disclosed to unauthorized individuals or entities. This principle is foundational in information security, as it ensures that access to information is restricted to those who are permitted to view it, thereby protecting it from breaches that could lead to unauthorized misuse or exposure. Maintaining confidentiality is crucial for safeguarding personal data, proprietary business information, and other sensitive materials against potential threats.

In contrast, the other options focus on different aspects of information security. For instance, guaranteeing that all data is backed up pertains to data integrity and availability rather than confidentiality. Similarly, stating that no security incidents should occur relates more to risk management and incident response, while the policy of sharing information with stakeholders does not align with the concept of confidentiality, as sharing information can compromise it if not managed correctly. Thus, recognizing confidentiality as the protection against unauthorized data disclosure is essential for understanding its role within the DSAC framework.
