What does confidentiality in the CIA Triad aim to achieve?

1. Ensuring data is available at all times

2. Preventing unauthorized disclosure of information

3. Detecting modifications in messages

4. Monitoring network activity

The correct answer is: Preventing unauthorized disclosure of information

Confidentiality in the CIA Triad is a fundamental principle that aims to prevent unauthorized disclosure of information. It ensures that sensitive data is accessible only to individuals or systems that have the appropriate permissions. This means implementing safeguards such as encryption, access controls, and policies to protect information from being accessed by unauthorized users or entities. The focus on preventing unauthorized disclosure is vital in various contexts, such as personal information, intellectual property, and corporate data, as breaches can lead to significant consequences, including financial loss and reputational damage. Therefore, maintaining confidentiality is essential for safeguarding sensitive information from prying eyes and protecting the integrity of communications and data storage. In contrast, the other options relate to different aspects of information security: ensuring data availability pertains to the principle of availability, detecting modifications is linked to integrity, and monitoring network activity relates to security practices rather than confidentiality itself.
