The correct answer is D. Confidentiality.
Confidentiality is the assurance that information is not disclosed to unauthorized individuals or entities. It is one of the three main pillars of information security, along with integrity and availability.
Confidentiality can be achieved through a variety of means, such as encryption, access control, and data masking. It is important to note that confidentiality is not absolute, and there are always risks that information may be leaked or compromised. However, by taking appropriate security measures, organizations can reduce the likelihood of this happening.
Here is a brief explanation of each of the other options:
- Availability: Availability refers to the assurance that information is accessible when needed. It is important to ensure that information is backed up and that there are redundant systems in place in case of a failure.
- Integrity: Integrity refers to the assurance that information is accurate and complete. It is important to have processes in place to verify the accuracy of information and to prevent unauthorized changes.
- Accounting: Accounting refers to the tracking of who has accessed information and what changes have been made. It is important to be able to track changes to information in order to identify unauthorized access or changes.
