FTP File Transfer

FTP, or File Transfer Protocol, is a standard network protocol used to transfer files between a client and a server over the Internet or local networks. It enables users to upload, download, rename, move, and delete files on a remote server, making it essential for data sharing, website maintenance, and system backups.

How FTP Works

FTP operates on a client-server model. Users connect to an FTP server using an FTP client (e.g., FileZilla), and authenticate with a username and password. Once connected, users can perform file operations as allowed by the serverā€™s permission settings.

FTP uses two channels:

  • Command Channel (Port 21): For control commands and authentication.

  • Data Channel (Port 20 or Passive Mode Port): For file transfer.

Conclusion:
FTP remains a vital tool in digital communications and surveillance systems. Whether used for backup, remote monitoring, or automation, it provides a flexible and scalable method of file management. To maximize security, implementing encrypted alternatives like SFTP is recommended in modern applications
