What is the primary goal of data encryption?

• A. To enhance data accessibility for users
• B. To protect sensitive data from unauthorized access
• C. To improve network performance
• D. To create copies of data for backup

Answer: (B)

The primary goal of data encryption is to protect sensitive data from unauthorized access. This process involves transforming readable data into a coded format that can only be deciphered by those who possess the correct key or decryption method. In scenarios where data privacy and security are critical—such as financial transactions, personal communications, and confidential business information—encryption serves as a vital protective measure against data breaches and unauthorized interception.

By encrypting data, organizations can ensure that even if data is intercepted during transmission or accessed without permission, it remains unintelligible and therefore useless to unauthorized individuals. This aspect of encryption supports compliance with legal and regulatory standards regarding data protection, which is essential for maintaining customer trust and safeguarding sensitive information.

The other options focus on different aspects of data handling; enhancing accessibility and improving performance are not directly related to encryption, while backing up data is more about data preservation rather than securing it against unauthorized access.
