File Transfer Protocol FTP is a network protocol for transferring copies of files from one computer to another. An FTP client is a program that allows you to move files between computers. For example, you can create web pages on your PC and use an FTP client to upload the website to the server where it will be hosted. Cite this Article Format. Roeder, Linda.

What is an FTP server? How does FTP work? As such, an FTP protocol requires two basic channels to establish a connection: Command channel: initiates the instruction, carries basic information, i. What problems does FTP solve? What are the pros of FTP? What are the cons of FTP? It leads to the fact that port 21 is of greatest importance, which is necessary for you to open the server and send commands to it and port 20 is needed mainly for active mode.

The client establishes actively a control connection to server port 21 it opens the connection passively to send FTP commands to the server and receive FTP responses from it. A control connection exists all the time while the client is communicating with the server.

On the 20th port server , in fact, data is transferred under the "supervision" of the control connection on port 21 server. This port is required for a connection that exists only at the data transfer. This distinguishes the specified connection from that on port 21, which exists all the time when the customer works with the server. If you start to analyze the situation it is not shiny. After all, the data transfer protocol is not at all protected from interception. At any time, experienced hackers can attack your server and intercept the password and login of the client.

Then they will infiltrate the server and steal important data from there, or they will hide malicious programs and viruses in directories. In order to somehow increase the security level of using the FTP protocol, it is recommended to change the standard FTP port in the settings, this is needed for connection.

It is not difficult to do this, but each server has this option configured in its own way. The only nuance is that when connecting, the client will need to specify a new FTP data port number instead of the number This is the essence of protection - hackers will not know the port on which to intercept data, therefore they will not be able to steal it.

The most significant drawback of the protocol is the transfer of all information, as well as usernames and passwords, in an open form. This makes it impossible to use this protocol to transfer confidential information without using third-party software and hardware. If the attacker has access to the communication channel through which this data is being passed, encryption must be used or secure FTP port number. The protocol does not define actions that counteract the selection of passwords.

After an incorrect password, the client is given the opportunity to re-enter it, but the connection is not disconnected. There are also no restrictions on the number of repetitions. As a result, an attack aimed at guessing passwords can last as long as you like, and the absence of delays in server responses increases efficiency.

The following vulnerabilities are associated with the passive mode of the protocol and the possibility of participation in the connection of the third node.

When using the passive data transfer mode, in which the server tells the client which FTP server port to connect to in order to start the transfer, it is possible to establish a connection from another computer. If the real client has already selected the file necessary for downloading and has the necessary access, then theft on his behalf is possible. An attacker, knowing the peculiarities of the choice of FTP port numbers by the FTP server for organizing passive mode, increases the likelihood of an attack success.

To do this, you must try to establish connections with the ports, and if everything is successful, the file will be stolen.

In the same way, you can write a file to the server on behalf of the registered user by establishing a connection with the FTP server port waiting for the file to start. Vulnerabilities of the protocol occurs mainly due to its features and the lack of ways to protect the transmitted information.

To increase security, you must use third-party tools, as well as carefully consider the interaction of network nodes via the FTP protocol. The problem of transferring all information in an open form is solved either by using encryption tools, where possible, or by protecting communication channels from unauthorized access.

With this app you will not bother anymore whether FTP port secure is or not and simply relay on the encryption feature of the app, as it uses AES with a bit key length. Besides that, the app supports a wide range of advanced features that are necessary when handling files, try this app to benefit from its functionality. Other problems can be solved by filtering. To protect passwords from busting, you must configure the FTP server so that connections are closed after a number of password attempts.

It is also necessary to provide a pause before responding to each incorrect password, which will significantly slow down their enumeration. To prevent file theft during passive mode, filtering by IP address is required. SFTP is a standard for transferring information on the Internet, which is designed to move and copy files using a connection of increased reliability and security SSH Secure Shell. This type of connection can provide access and secure transmission, which is encrypted with both login and password, as well as the contents of the transmission, thereby protecting passwords and confidential information from open transmission on the network.

The main purpose of FTP is to send, copy, transfer, files on the Internet from a remote computer to a local computer and vice versa. In addition, using FTP, you can work with your files directly on a remote computer rename, delete, create directories, etc. For example, it allows users to transfer a large file and use the synchronizing utility. There are many FTP clients to choose from. From free open-source applications to premium options. So there you have it, you can send and recieve files from an FTP server.

Furthermore, it is easier to create and remove directories and read a large number of files on the server. We hope this article helps you to understand FTP as well as the different methods and programs used.
