Which of the following is a component of Data Security?

Data Encryption is a critical component of Data Security as it involves implementing techniques to encode data, making it unreadable to unauthorized users. This ensures that even if data is intercepted or accessed without permission, it remains protected because it cannot be easily understood without the decryption key. Encryption is essential for safeguarding sensitive information against various threats, including data breaches and unauthorized access, which is increasingly important in today's digital landscape where data is often stored and transmitted over potentially insecure networks.

The focus of data security is primarily on protecting data integrity, confidentiality, and availability, and encryption specifically addresses the confidentiality aspect by rendering the data unreadable to those without proper authorization.
