What role does encryption play in data security?

Encryption plays a crucial role in data security by disguising data, which helps to prevent unauthorized access. When data is encrypted, it is transformed into a format that can only be read or decrypted by someone who possesses the correct decryption key. This process ensures that even if the data is intercepted or accessed by an unauthorized individual, it remains unreadable and protected.

The primary purpose of encryption is to maintain confidentiality and integrity, making it an essential component in securing sensitive information. It protects personal data, financial information, healthcare records, and any other confidential communications from potential threats such as cyber attacks or data breaches.

In contrast, the other options do not accurately represent the key function of encryption in data security. While increasing data volume, faster data retrieval, and easier sharing are aspects related to data management, they do not pertain to the protective measures that encryption provides.
