The more ports you open, the more opportunities hackers get to access your network and your data. However, while SFTP uses a single port number for all communications, FTPS makes use of multiple port numbers. SFTP differs from FTP by having an extra security layer and adding protection through authentication options to access and modify content. That’s where SFTP and FTPS come into play. Back when it was developed, it was considered that no malicious activity can be performed on the Internet so it doesn’t include any safety features. The standard file transfer protocol, FTP, does not offer any security layers when transmitting files. You will easily find an FTP program for Mac to easily download, upload, and manage content thanks to its longevity. The same system is used for uploading, renaming, deleting, copying, or moving files.ĭespite the development of other file transfer protocols, FTP remains the most widely used thanks to its efficiency and versatility. Then, through the above-mentioned channels, the file is downloaded to the user’s computer.
To use FTP a user needs to first log on to a specific FTP server and initiate a “conversation” with that server to request the download of a file. More explicitly, FTP is a client-server protocol that requires a command channel that consoles the conversation between two computers and the data channel where the content is actually transmitted. So, it’s a network protocol for transmitting files between two computers.
