What is the primary role of encryption in data security?

• A. To increase data speed
• B. To protect data by converting it into a code
• C. To simplify data management
• D. To enhance user experience

Answer: (B)

The primary role of encryption in data security is to protect data by converting it into a code. This process transforms readable information into an unreadable format, making it accessible only to those who possess the appropriate decryption key. By securing data in this way, encryption ensures confidentiality, integrity, and authenticity, preventing unauthorized access and safeguarding sensitive information from potential breaches or cyberattacks.

When data is encrypted, even if it is intercepted, it remains unintelligible without the decryption mechanism, thereby significantly enhancing the security posture of the data in question—whether it is in transit or at rest. This process is fundamental in various applications, such as securing communications, protecting personal data, and ensuring safe storage of confidential information.

The other options do not fully capture the essential function of encryption. For instance, while improving speed, simplifying management, or enhancing user experience can be beneficial in different contexts, they do not pertain to the core purpose of encryption, which is primarily focused on ensuring data security and confidentiality.
