To access the system data (file) resources, specially built software is used at the user level. This software can be run locally on the user computer and remotely on the remote application server. In both cases, communication with the database server (file server) takes place using network resources. Network resources are the slowest component in the system. Software that communicates with the file server can use different network protocols. This paper analyzes different file transfer protocols at the application layer of the OSI model. Security mechanisms used in the analyzed protocols are explained. Timing and speed of transferring files in the LAN at the speeds of 10Mbps, 100Mbps and 1Gbps, and the unprotected and protected (VPN), WAN network were measured and noted. It is shown that the protocols that use security mechanisms are slower than those that do not use security mechanisms. It is also shown that the use of FTP HTTPS secure protocol is an optimal solution - high level of security and non-significantly lower speed.
