Answer:
The correct answer is Blind FTP.
Step-by-step explanation:
FTP (File Transfer Protocol) is a file transfer protocol between systems connected to a TCP network based on the client-server architecture, so that from a client computer we can connect to a server to download files from it or to send our own files regardless of the operating system used on each computer. It is blind when it protects itself from external attacks or intrusion from other servers that try to access through other platforms of the same website.
