FTP

FTP is a protocol used via the interent to transfer files.
With researching the risks of using FTP I came across this site which mentioned the risks are,

• A user's name and password are transferred in clear text when logging on and can therefore be easily recognized.
• When using an FTP connection, the transferred data could "stray" to a remote computer and not arrive at their intended destination. Third parties can then download data from the remote system to their own computers, or existing data can be viewed and edited. This presents a significant risk, particularly when transferring company confidential information.
• FTP can also be used to determine the passwords of individual users, since the password is transferred in clear text when logging on. As a result, even those with unauthorized access to this network can record the password information.

It mentions ways to minimize the risk would be to use SFTP which stands for safe file transfer protocol.
other things which could be done to minimize the risks would be don't use the same passwords for multiple things and don't send material which is sensitive.
