Which of the following is a security limitation of File Transfer Protocol (FTP)?

File Transfer Protocol (FTP) is a protocol that enables the transfer of files between a client and a server over a network. FTP has a security limitation in that it does not encrypt the authentication process, meaning that the username and password are sent in clear text over the network. This exposes the credentials to interception and eavesdropping by unauthorized parties, who could then access the files or compromise the system . References: : CISSP All-in-One Exam Guide, Eighth Edition, Chapter 5, page 533. : CISSP For Dummies, 7th Edition, Chapter 5, page 155.
