How does encryption enhance data security?

Encryption enhances data security by converting data into a coded format that can only be accessed or read by individuals who possess the appropriate decryption key. This process renders the original data unreadable to unauthorized users, thus protecting sensitive information from breaches or unauthorized access.

By transforming readable data (plaintext) into a scrambled version (ciphertext), encryption ensures that even if data is intercepted during transmission or accessed from storage, it remains secure and confidential. This is critical in fields such as finance, healthcare, and communication, where safeguarding personal and sensitive information is of utmost importance.

The other options, while important components of a broader data security strategy, do not directly relate to enhancing the security of data through encryption. Backing up data protects against data loss, organizing data improves user interaction, and training personnel is crucial for compliance and proper data handling but does not involve the technical process of encrypting data.
