What is the primary goal of confidentiality in cybersecurity?

1. Protection from unauthorized modification

2. Protection from disruptions in access

3. Protection from unauthorized access

4. Protection from harmful actions against assets

The correct answer is: Protection from unauthorized access

The primary goal of confidentiality in cybersecurity is to protect information from unauthorized access. This involves ensuring that sensitive data, such as personal information, financial records, and proprietary business information, is only accessible to individuals who are authorized to view it. The significance of confidentiality lies in preventing data breaches and leakage that could result in identity theft, financial loss, or damage to an organization's reputation. Confidentiality measures often include encryption, access controls, and authentication protocols. By rigorously implementing these measures, organizations can safeguard their information assets from being exposed to individuals or systems that should not have access. In contrast, while the other goals mentioned focus on different aspects of cybersecurity—such as integrity, which deals with unauthorized modifications, availability that relates to ensuring access to information when needed, and overall security against harm—they are not the primary focus of confidentiality. The essence of confidentiality is solely centered on restricting access to private information, ensuring that it remains exclusive to intended users.
