What does data encryption at rest in Azure Blob Storage primarily exemplify?

Integrity
Availability
Confidentiality
Authentication

The correct answer is: Confidentiality

Data encryption at rest in Azure Blob Storage primarily exemplifies confidentiality. This process ensures that the stored data is not accessible to unauthorized users, thereby protecting sensitive information from being exposed. Encryption transforms the data into a form that can only be read or deciphered by those who have the proper decryption keys or credentials. By safeguarding the data in this manner, Azure Blob Storage maintains the privacy and confidentiality of the data against potential threats such as hacking or data breaches. In the context of data security, integrity refers to the accuracy and completeness of data; however, encryption primarily addresses the protection of data from unauthorized access rather than its correctness. Availability pertains to ensuring that data is accessible to authorized users when needed, while authentication involves verifying the identity of users accessing the data. The focus of encryption at rest is distinctly on maintaining confidentiality, making it the best representation of this concept.
