Which of the following is a reason to use encryption for sensitive data?

Using encryption for sensitive data is fundamentally important because it protects both the integrity and confidentiality of that data. Encryption transforms data into a coded format that can only be deciphered by those who possess the specific key or passphrase. This means that even if unauthorized parties gain access to the encrypted data, they will not be able to understand or manipulate it without the proper decryption mechanism.

Confidentiality is preserved through encryption since it prevents unauthorized access to sensitive information, ensuring that only intended recipients can access the original data. Additionally, data integrity is maintained because encryption can help detect unauthorized alterations; if the encrypted data is tampered with, it will not decrypt as intended, thereby signaling a potential breach or corruption.

In contrast, options regarding increased visibility, slower access, and resource intensity do not provide valid reasons for employing encryption. In fact, encryption is typically employed to secure data rather than make it more visible, and while it may add some processing overhead, this is a trade-off for enhanced security.
