(FTP) is a widely used network protocol for transferring files between computers over a TCP/IP-based network (such as the Internet). FTP allows people and applications to exchange and share data in their offices and over the Internet. FTP was one of the first technologies developed to address this common need, and after several generations of enhancements, it is still the second most popular protocol in use today (after HTTP or the "World Wide Web"). FTP application FTP is used in many daily business operations, including business-to-business and peer-to-peer data transfer use cases: Organizations use FTP to allow employees to share files across different locations and branches; employees use FTP to securely share files with colleagues and external business partners; IT teams use FTP to transfer data back to the disaster recovery (DR) site; webmaster teams use FTP Transfer web pages, web application files, and images to their web server. How to transfer files via FTP? The file transfer protocol works in a client-server model, where the and FTP client perform file transfer operations. Configure an FTP server in the network and determine a specific file storage location (folder/system) to become shared storage, which will host the files you want to share. End users will access this file server via FTP to start copying files to their local folder/system. FTP requires a TCP/IP network to run, and it relies on the use of one or more FTP clients. The FTP client acts as a communication agent to interact with the server and download or upload files. In other words, the FTP client sends a connection to the FTP server. After the FTP server monitors the client's request for uploading or downloading a file, it executes the file transfer operation. What is the use of an FTP client? Decades ago, FTP clients were just command-line interface (CLI) applications. They now provide an easy-to-use, intuitive interface to facilitate and simplify file transfers. FTP clients are used on desktops, servers, and mobile devices, and they can be used as simple extensions to stand-alone applications, web clients, and web browsers. Active and passive FTP server connection The FTP server can support active and passive connections with FTP clients. In an active FTP connection, the client opens a port and listens when the server actively connects to it. In a passive connection, the server opens a port and passively listens, which allows the client to connect to it. Passive connections are more secure, and IT administrators prefer them because the data connection is from the FTP client to the FTP server. This is a more reliable method, which avoids inbound connections from the Internet to a single client. In a firewall deployment, all connections are from the Internet to the server, not from the server back to the Internet. Passive mode is also called "firewall-friendly" mode. The more secure the file transfer protocol (such as SFTP, FTPS) supported by the FTP client, the more secure it is. FTP has been around for more than four years, and it has witnessed major changes in encryption standards and file transfer capabilities. This chart records the evolution of FTP and the introduction of hosted file transfers. It provides support for secure protocols (such as FTPS and SFTP) and advanced management functions for secure and controlled file transfers. The is a core technology by Raysync based on the UDP protocol, which can overcome the limitations of traditional networks and hardware, the bandwidth utilization rate is more than 96%, and the transmission speed is 100 times faster than FTP. It can easily meet the safe, fast, and stable transmission requirements of TB-level large files and massive small files.
(FTP) is a protocol used to move files on the Internet. It is unique in that it uses two different connections. The control connection is used to send commands between the FTP client and the FTP server. File transfers are sent on a separate connection called a data connection. FTP packet filters can handle active and passive FTP sessions without any special client configuration. Inactive mode FTP, the FTP server establishes a data connection. In passive mode, the client establishes a connection. Generally speaking, FTP user agents use active mode, and Web user agents use passive mode. Like the FTP packet filter, the FTP proxy handles active and passive FTP sessions, but it also protects your FTP server and restricts FTP protocol commands between the client and the server. You can use an FTP proxy to: 1. Restrict the commands sent on the control channel 2. Restrict the file name or file type according to the extension 3. Prevent buffer overflow attacks caused by abuse of the FTP protocol 4. Abnormal use of FTP commands through WatchGuard intrusion prevention service to prevent unauthorized directory traversal After adding the FTP proxy policy to the Firebox configuration, you can access the two proxy actions included in the product. You can use these rule sets without changing them, or you can use these rule sets as the basis for rule sets to meet the needs of your organization. This module shows you how to customize these two agent operations. FTP-Client This proxy operation includes a rule set that controls FTP commands launched on computers on your trusted or optional network. The FTP client application uses specific commands that the Firebox can recognize and control. Use FTP-Client operations to control the outgoing FTP traffic. FTP-Server This proxy operation includes a rule set for protecting and controlling FTP commands sent to your FTP . Use FTP-Server operations to control incoming FTP traffic.
What are FTP () and a complete description of SFTP and TFTP? FTP, SFTP, and TFTP are protocols used to transfer files over the network. File Transfer Protocol (FTP) This is a standard protocol used to between a computer and a server over a network (such as the Internet). FTP is a larger file used by computers to transfer files over a TCP/IP network. If someone anywhere in the world wants their file to be available, all the other person wants to download is upload the file to an FTP server. Anyone in the world can connect to the FTP server and download files using the FTP protocol. Here we use a dedicated FTP server to , but there is no need to set up a dedicated server for FTP because they hope that they can configure their computer to act as an FTP server. In Microsoft Windows, this can be done in the Internet Information Services Manager. There are several ways to use FTP to transfer files. Here we use a standard Internet browser or use an FTP client. For example, let's download an MP3 file uploaded by someone on an FTP server. Let's use a standard Internet browser, open a web browser type in the address FTP server, or visit a regular website if necessary. The URL of the FTP server is the ftp.example.com type address in the URL. When we visit a regular website, the prefix will be HTTP, because we are going to an FTP site, and the prefix is FTP.Now it connects to the FTP server. It is an example of viewing a web browser on an FTP server. We can browse different types of folders on the FTP server according to the available content, and download the content we need. Select MP3 on your computer and download it. Sometimes the FTP server will regain an account with a username and password, and sometimes we can log in anonymously. This depends on the type of authentication of the owner of the FTP server settings. Other connected FTP servers in the FTP client. There are many FTP client users. Perhaps the most popular free FTP client is Filezilla. The FTP client provides a graphical user interface for a better experience than using a web browser. In the web browser, the web address is the FTP server and the user and password (if required), and the port number is 21. Press the connect button and it will connect to the FTP server. Files and folders on our computer in the left panel The files and folders in the right panel are remote FTP servers. Click from the right panel and drag from the , such as MP3 files, and then click them or drag from the left panel to your computer. If you have the proper permissions, you can upload files from our computer to the FTP server through the left-to-right panel. The file will be uploaded to the FTP server. Transferring files between computers is a commonly used file transfer protocol. Especially batch transfer of files. Another common use of FTP enables website designers to upload files to their web server. The main disadvantage of using FTP is that the insecure protocol data it transmits is not encrypted. All data sent is in plain text. Which ones can cause safety issues? FTP should indeed be used on a limited basis, or only use a trusted network or send data that is not sensitive. However, to transfer the data to be protected, a more secure protocol should be used. Secure File Transfer Protocol (SFTP) The protocol is like FTP, which adds a layer of security. The data using SFTP is encrypted using a secure shell during data transmission. No data is sent because all plaintext is encrypted. SFTP authenticates users and servers and uses port 22. Both FTP and SFTP are connection-oriented protocols. They all use TCP for file transfer, so file transfer can be guaranteed. Trivial File Transfer Protocol (TFTP) This is a very simple file transfer protocol. It is not used to via the Internet, such as FTP and SFTP. TFTP is mainly used to transfer files within a local area network.
Enterprises rely on safe and reliable information access methods to meet today's rapidly developing market demand. Accordingly, sharing data internally and externally is essential for any organization. File Transfer Protocol FTP is one of the earliest and still used data sharing methods. Although IT teams and business users are familiar with this, FTP lacks much vital security, compliance, and workflow requirements in modern organizations, especially in data security. The following are four different FTP vulnerabilities attacked by hackers: 1. Anonymous authentication Anonymous authentication is an FTP vulnerability, which allows users to use FTP username or log in anonymously. In many cases, users will provide their email address as a password. However, the user's login credentials (username and password) and the commands used are unencrypted, visible, and easy to access. At the same time, any data sent via FTP or hosted on an anonymous FTP server will not be protected. Once, the FBI found that hackers actively used FTP to target medical and dental industries and access protected health information. 2. Directory traversal attack Directory traversal attack is another FTP vulnerability, and its successful attack will overwrite or create unauthorized files, which are stored outside the Webroot folder. In turn, the original FTP owner is subject to the permission of files or directories and the control of hackers. 3. Cross-site scripting When attackers use Web applications to send malicious code, XSS attacks are usually sent to end-users in the form of browser-side scripts. Defects that allow attacks to succeed are very common and may occur anywhere where user input is used without verification or coding in the output generated by Web applications. Attackers can use XXS to send malicious scripts to unsuspecting users. The end user's browser cannot know that the script is not trusted and execute the script. Because the malicious script thinks that the script comes from a trusted source, it can access any data, session token, or other sensitive information stored on the user's local terminal that is reserved by the browser and used with the site. 4. Malware attack based on Dridex It was discovered for the first time in 2014 that Dridex malware has been re-invented and introduced in unexpected ways after the UK became the target of bank attacks. Internet users targeted by Dridex malware will open Word or Excel email attachments, which will cause macros to download the malware and infect computers, thus exposing users to bank theft. In the latest version of Dridex malware, hackers use FTP sites and credentials to avoid being detected by e-mail gateway and network policy of trusted FTP. Updating FTP credentials regularly can help prevent Dridex-based attacks. As far as the FTP server itself is concerned, it can no longer meet the system functions required by the big data business in the information age. From the point of view of security, transfer efficiency, and compliance, the FTP server itself cannot be expanded and it is very likely to bring high-cost loss. In the big data market, big file transfer (MFT) software came into being and was promised to meet the above business requirements. Large file transfer technology provides higher control and security than FTP, which usually has the following features: - In-depth report (e.g., notification of completion of file transfer) - The global visibility of all activities - End-to-end security, encrypting data in transit and at rest - Performance indicators, monitoring, and support for compliance requirements - Workflow automation Raysync- large file transfer software High performance Raysync high-speed transfer protocol, the bandwidth utilization rate is over 96%, the transfer rate is increased by 100X, and TB-level large files and massive small files are easily transmitted.

As the head brand of enterprise-level , Raysync has provided high-performance, stable, and secure data transfer services for 2W+ enterprises in IT, finance, film and television, biological genes, manufacturing, and many other fields. In some cases, a large file transfer platform can be used together with FTP in the process of transition to safer and more effective information flow (such as Raysync FTP acceleration).
Before you choose a , it is best to have a basic understanding of the protocols involved, which make file transfers safe and reliable. 1.FTP The has existed for decades and has been widely used in the past. TCP provides reliable data transfer through message sequence confirmation and message retransfer mechanisms; at the same time, various widely used operating systems (WINDOWS/LINUX/UNIX/MAC) have built-in TCP protocol stacks, and POSIX standards define the TCP Socket standard API interface, these factors have contributed to TCP's widespread success on a global scale. However, this transfer protocol, which was designed more than 20 years ago, has become increasingly unsuitable for the rapidly developing network environment and the requirements of new applications, especially when there are a certain packet loss and delay on the network transfer path. Transfer throughput declines sharply, and path bandwidth is often not used effectively, resulting in slow transfer speed, long transfer time, and poor transfer experience. 2.FTPS FTPS is an extension protocol that adds Transport Layer Security (TLS) and Secure Socket Layer (SSL) encryption protocol support to the commonly used file transfer protocol (FTP). FTPS is a secure file transfer protocol that allows you to communicate with trading partners, Clients and users transfer files securely. These transfers can be authenticated through methods supported by FTPS (such as client certificates, server certificates, and passwords). 3.SFTP In the computer field, it is designed by the Internet Engineering Task Force (IETF) to provide secure file transfer capabilities through the expansion of SSH-2, but it can also be used by other protocols. Even though the IETF is in the network draft data stage, this protocol is described in the SSH-2 document, it can be used in many different applications, such as secure file transfer in Transport Layer Security (TLS) and transfer information management in virtual private network applications Program. This agreement is assumed to be executed in a secure channel, such as SSH, the server has authenticated the client, and the client user can use the agreement. Compared with the earlier SCP protocol that only allows file transfer, SFTP allows a wider range of operations on remote files ─ which is more like a remote file system protocol. A comparison of the capabilities of an SFTP client and SCP includes additional replies to interrupt transfers, directory listings, and remote file movement. 4.SCP The old protocol, SCP or Secure Copy Protocol, is a network protocol that supports file transfer between hosts on the network. It is similar to FTP, but SCP supports encryption and authentication functions. 5.HTTP & HTTPS As the backbone of the World Wide Web, HTTP (Hypertext Transfer Protocol) is the basis of data communication. It defines the message format of the communication between the web browser and the web server and defines how the web browser should respond to web requests. HTTP uses TCP (Transfer Control Protocol) as the underlying transfer and is a stateless protocol. This means that each command is executed independently, and the receiver does not retain session information. Https (Hypertext Transfer Protocol Security) is a secure version of HTTP in which communications are encrypted by TLS or SSL. 6.AS2, AS3, and AS4 AS2, AS3, and AS4 are popular protocols used to send and protect critical file transfers. AS2 is used to transmit sensitive data safely and reliably on the Internet. AS2 uses digital certificates and encryption standards to protect critical information transmitted between systems, networks, and locations. AS 2 messages can be compressed, signed, encrypted, and sent through a secure SSL tunnel. AS3 is a standard and can be used to transfer almost any file type. It provides a layer of security for data transfer through digital signature and data encryption. It was originally created to transfer data files, such as XML and EDI business-to-business data files. Unlike AS2, AS2 is a defined transfer protocol, and AS3 is a message standard that focuses on how to format a message when it is sent from the server to the server. Once the AS3 message is synthesized, it can be transmitted via any other protocol (FTP, SFTP, HTTPS, etc.). As long as both parties can access the location where the message has been placed. AS4 is an agreement that allows companies to exchange data securely with their partners. It is based on what was originally set up by AS2, but works with web services and provides improved delivery notifications. As a business-to-business standard, AS4 helps make file exchange on the Internet safe and simple. 7.PeSIT PeSIT protocol is an end-to-end file transfer protocol developed by the French Interbank Telecommunications System Economic Interest Group (GSIT). It is rarely used in North America and is mainly used to meet European banking standards and to transfer communications to and from European banks. Knowing these 7 file transfer protocols, you probably know how to choose a protocol to ensure the secure transfer of your .
FTP protocol originated from the early days of network computing. A few government and university researchers explored the value of connecting computers together, so they created FTP protocol to promote the in the network. Why do so many people still use FTP now? Because it is perfect and embedded in most operating systems today. Although FTP is provided free of charge, it does not mean that it has no cost. IT teams spend too much time managing and maintaining FTP servers and their users, which could have been devoted to more important IT projects and plans. Security Many changes have taken place in FTP since it was invented, especially the security and confidentiality. FTP predates the Internet as we know it today, but it is not designed to transfer files safely. When companies use it to send files containing personally identifiable information or patient data, compliance does not exist. FTP has no resistance to many types of attacks, and the user name and password credentials are sent in clear text. It is not difficult for hackers to extract information and access the entire server containing company data. Ease-of-use FTP is mainly an IT tool. Many IT professionals still like to run FTP in command line mode, and take pride in managing servers through text commands, but for ordinary knowledge workers, FTP operation is too technical. FTP client software can help, but it is only an overlay, which will not increase security or reduce manual management of FTP server. The complaints that FTP administrators often hear are managing users and their credentials, and knowing which files should be saved on the server and which files can be deleted. This causes the FTP server to become very bloated. As time goes by, the files on the FTP server continue to accumulate, and the situation will get worse and worse. What transfer tools do we use now? Today's solutions can meet today's growing demand for secure file transfer. It's time to adopt a more modern and powerful data transfer solution. As time goes by, your company will benefit from this, operate within the scope of compliance standards, and become more efficient after the final rest of FTP.
FTP traditionally has been the most common way to exchange files over the internet for years. FTP-FTPS-SFTP seems to be an update of FTP, but is this real? Or as everyone has said, that the progress of new technologies has made FTP obsolete? If you are currently using FTP and looking for an alternative that provides visibility, control, and automation while improving security and manageability – this article takes a deep dive into what FTP is, its attributes and gives you the info you need to consider replacing FTP with a better file transfer solution. is a method of transferring data files from one computer to another over a network. As one of the original programs for accessing the information on the internet, it was developed in 1971 as part of the U.S. Department of Defense’s ARPANET protocols and thus predates both the TCP and Internet Protocol (IP). FTPS and SFTP FTPS and SFTP are two separate protocols used as secure alternatives to traditional FTP. Often mistaken for each other, these are two very distinct protocols with different pros and cons: FTPS (also known as FTP Secure, FTP-ES, FTP-SSL) is an extension to the commonly used File Transfer Protocol (FTP) that adds support for the Transport Layer Security (TLS) and the Secure Sockets Layer (SSL) cryptographic protocols. SFTP (SSH File Transfer Protocol) is a secure alternative to FTP and is often mistakenly used to specify some kind of Secure FTP, by which people most often mean FTPS. SFTP is a binary protocol in which all commands are packed to binary messages and sent to the server, which replies with binary reply packets. Why Replace FTP? Since FTP is typically used to solve a single problem or meet a specific application requirement, it usually results in multiple discrete deployments with no central management and control — leading to many business challenges for enterprises, which is not visible at the surface. Here are some driving factors for replacing FTP: Security There are a number of risks associated with using native FTP such as having FTP port open in firewalls and a lack of encryption. Exchanging information without the necessary security features could lead organizations to face massive fines in the event of a breach or a public relations disaster. Lack of Visibility When sending files via FTP, the sender has no way to verify whether the recipient received or downloaded the file or not. Also, since FTP doesn’t maintain an audit trail of system actions such as who downloaded or transferred files, organizations don’t have detailed proof of user actions. Storage Overhead FTP doesn't allow sender to automatically expire or delete files. The file will be deleted until the IT administrator delete it, consuming significant storage space and incurring unnecessary costs. Cumbersome Workflow It is difficult and complexed to manage FTP, if you want to send the file to a new contact, you need to set a new FTP account. Because the users have no right to access the FTP server, thus they need to repy on the help of the IT administrator to create the new accounts, retrieve forgotten passwords and remove accounts for those who no longer require access. Alternative to FTP As the enterprise-level expert, Raysync replaces the FTP server via the secure file sharing platform, and builds the ultra-high-speed transfer engine to realize all internal and external file transfer management of the enterprise and fast and safe file distribution worldwide. Some of Raysync's differentiating features include: Easy to Management The deployment process will be troublesome and hard to manage if there are many files to be transferred. Raysync Transmission supports different types of protocol, based on the self-developed transfer engine, Raysync can transfer the large files and the vast amount of small files at maximum speed. It is convenience for organization to manage the whole transfer process from a central control board. Security and Permission Raysync helps organizations remain compliant with strict regulations by providing security features to monitor user actions, regulate access, and secure corporate data. All data in flight and at rest are protected with encryption and antivirus scanning. High-performance Transfer Whether it is the current TB-level big across borders or massive small file transfer, these are all routine for enterprises nowadays. FTP simply cannot meet the needs of the fast-growing big data era. Raysync Transmission is a high-speed transfer engine based on UDP research and development. Compared with FTP, the transfer speed is 100 times higher, and the bandwidth utilization rate reaches 96%. It can easily cope with the high-speed transfer demand of enterprise-level files. Seamless Integration As far as deployment and integration are concerned, Raysync Transmission provides the most flexible FTP alternative. Raysync Proxy supports seamless integration of various popular softwares such as FTP/Http/ssh/SCP/Rsync, etc. Raysync Transmission can easily replace the old FTP server, quickly complete deployment within 30 minutes, realize high-speed and safe access to collaborative data within and between enterprises in the global position, reduce the high cost of R&D and design, and save the time needed for deploying and monitoring important file transfer. can be run as a process alone, with extremely low resource consumption, CPU consumption of less than 20% at 100Mbps data throughput, and memory consumption of management structure of single connection of less than 30KB.
In the process of enterprise management and , FTP is actually one of the most commonly used software systems. However, with the continuous development of enterprise business and the increasing volume of files, in practice, it is not difficult to find that FTP is becoming less and less practical, so the data transfer mode based on FTP purchase can no longer meet an application demand of enterprises. Let’s analyze the reason why FTP is becoming less and less practical in our daily life, there have 5 reasons: 1. It takes a long time to transfer those large files and massive small files via FTP, if the transfer process is interrupted, the files will likely be lost or damaged. 2. The logs of FTP in the process of transfer is invisible and can’t be traceable. 3. Because of the activeness of the public cloud, enterprises' funds in the cloud are often distributed in different cloud service providers or multiple areas of the same service provider according to different needs of business support. If the data in different locations on the cloud can be exchanged in real-time, different business modules can be effectively connected, which is a new problem that enterprises will face. 4. FTP has poor applicability for complex networks, especially under firewall architecture. Ordinary FTP does not encrypt data locally during transfer or storage. In such a situation, there is the risk of leaking data and files, which is very serious and greatly reduces security. 5. More and more enterprises need to distribute and summarize the data, but the FTP can’t provide a corresponding solution. Thus, the enterprise needs to apply another solution, which can not only meet the requirements of fast, safe, and stable data, but also realize the synchronous distribution of data backup. , transnational network data transfer, file management and organization authority management. It supports local deployment and cloud storage services, provides enterprises with safe, stable, efficient, and convenient technical support and services for large file interaction, and maximizes office efficiency.
