Trivial File Transfer Protocol (TFTP) is a lightweight, connectionless protocol that operates on UDP port 69, primarily used for booting diskless workstations, updating device firmware, and backing up network configurations. Because it lacks native authentication and encryption features, mastering the right tools and deployment practices is vital to maintaining a secure network infrastructure. Core Use Cases of TFTP
Network Booting: Delivering bootloader files, operating system kernels, and installation images via Preboot Execution Environment (PXE).
Firmware Upgrades: Flashing system updates onto resource-constrained embedded systems, VoIP endpoints, routers, and switches.
Configuration Backups: Exporting and importing raw startup configuration text files to and from network infrastructure switches. Top TFTP Server Tools
