FTP is an acronym for file transfer protocol. It was designed originally as one of the first internet protocols. FTP makes it possible to transfer large files of data via the internet. FTP was initially intended to be used on a closed system which is why it was not intended to be a secure way to transfer files. On modern networks this presents a big concern for information security because traditional FTP sites have little to no security features.
There are two modes which users can select to use with FTP and are active mode or passive mode. FTP uses different TCP/IP ports, the communication language of the internet, depending on which modes users choose. TCP/IP ports are used to help ensure information is properly sent and received between two operating machines. There are specific steps for each mode that users must follow in order to successfully transfer files. In the past users defaulted to active mode but passive mode has gradually become more common.
One of the major reasons why FTP presents so many security issues is that it sends information in clear text, that is, unencrypted. Anyone with the proper protocol tools can intercept and view this information. Many companies that need to transfer highly confidential information on a regular basis will not even consider using traditional FTP sites for this reason. Also, FTP sites are not typically easy to manage because in the past they have been known to experience a wide array of technical problems. Connecting to an FTP server can be quite tedious as well, but once connected they are extremely user friendly.
Traditional FTP sites lack of security is why companies are no longer using them as much and have switched to other large file transfer services, such as ShareFile. These file transfer services have made great improvements upon the ability to transfer files in a fast and efficient manner while maintaining a high level of information security.
