file transfer protocol (ftp) is an internet protocol for the transfer of files between a server and a client. its most common use is to transfer files between a user and a website. ftp supports the transfer of files from a remote server to a client computer and vice versa. ftp is commonly used to upload files to web servers, to transfer files from one computer to another, to share files among groups of users or to download files from web servers. ftp is insecure by nature due to the fact that it does not use any form of encryption or authentication. this means that the contents of the file are visible in plain text when transferred using ftp. the use of ftp to transfer sensitive information is risky because the contents of the file are not encrypted. theft of unencrypted, sensitive information is considered a crime, and theft of encrypted information is considered a violation of the law in most countries. in these countries, theft of unencrypted data is punishable by fines, imprisonment, and the confiscation of the material and its use. its a well-known fact that unencrypted information can be easily read by anyone who knows how to. now theres a new layer of risk for organizations that use ftp to transfer critical data.
