Answer:
File transfer protocol secure (FTPS)
Explanation:
File transfer encryption is an essential security measure that prevents outsiders from being able to read or understand the data that is being transferred. This protects the information from potential hackers.
There are three options for encrypting file transfer data: FTPS (File Transfer Protocol Secure), FTP (File Transfer Protocol) and HTTPS (HTTP Secure).
File Transfer Protocol (FTP) and File Transfer Protocol secure (FTPS) are used for transferring files. However FTPS is the only secure, encrypted protocol.
