What security feature does sFTP provide during data loading?

sFTP, or Secure File Transfer Protocol, is designed to enhance the security of data transfers over networks significantly. One of its primary features is data encryption, which ensures that the information being transferred is scrambled and can only be interpreted by authorized parties. This encryption protects sensitive data from being exposed to unauthorized users during transmission, thus preserving its confidentiality.

In addition to encryption, sFTP also provides robust user authentication. This feature ensures that only users with the proper credentials are permitted access to the system and can interact with the data. Various methods of authentication are available, including password-based and key-based authentication, adding another layer of security to the data loading process.

Given these two essential features—data encryption to maintain confidentiality during transmission and user authentication to ensure that only authorized users have access—the correct assertion is that sFTP provides both protection mechanisms during data loading tasks.
