FTP traffic does not provide encryption in the data transfer process, and the data transfer between

the sender and receiver is in plain text. FTP stands for File Transfer Protocol, and it is a standard

network protocol for transferring files between a client and a server over a TCP/IP network. FTP uses

two separate channels for communication: a control channel for sending commands and receiving

responses, and a data channel for transferring files. However, FTP does not encrypt any of the data

that is sent or received over these channels, which means that anyone who can intercept the

network traffic can read or modify the contents of the files, as well as the usernames and passwords

used for authentication. This poses a serious security risk for the confidentiality, integrity, and

availability of the data and the systems involved in the file transfer. Therefore, FTP is not a secure way

to transfer sensitive or confidential data over the network. Reference:
