FTP stands for File Transfer Protocol. It is a standard network protocol used to transfer files from one host to another over a TCP-based network, such as the internet. FTP is often used for uploading files to a web server or downloading files from a server to a local computer.
While FTP has been widely used in the past, more secure and modern alternatives like SFTP and FTPS are often preferred today, especially for sensitive data transfer. These secure protocols add encryption to the data transmission, making them more suitable for secure file transfers over the internet.
KEY FEATURES AND ASPECTS OF FTP
- Client-Server Model: FTP operates on a client-server model. The client initiates a connection to the server to request files or to send files to the server.
- Two Modes of Operation:
Active Mode: In this mode, the client opens a random port for data transfer, and the server connects to that port. It’s less commonly used today due to security and firewall issues.
Passive Mode: The client opens two random ports, one for the command connection and another for data transfer. The server connects to the data port specified by the client. Passive mode is more firewall-friendly. - Authentication: FTP typically requires a username and password for authentication. Some variations of FTP also support anonymous logins, allowing users to log in with a generic username like “anonymous” or “ftp” and provide their email address as a password.
- Security Concerns: Traditional FTP sends data in plain text, including usernames and passwords, which poses security risks. To address this, secure versions of FTP exist, such as FTPS (FTP Secure) and SFTP (SSH File Transfer Protocol), which provide encryption for data transmission.
- Commands: FTP uses a set of commands to perform various operations, such as navigating directories, uploading and downloading files, deleting files, etc.
- Port Numbers: FTP uses port 21 for command and control and another port (usually port 20 for active mode or a randomly chosen port in passive mode) for data transfer.
