File Transfer Protocol Server is a computer that provides file storage and access services on the Internet. They provide services in accordance with the FTP protocol. FTP, the file transfer protocol is a set of standard protocols for file transfer on the network, using the client/server model. FTP is a protocol specifically used to transfer files. FTP is a client/server system. Users use a client that supports the File FTP Protocol connect to a server program on a remote host. The user issues a command on the client, and the remote host server executes the command issued by the user after receiving the command, and returns the execution result to the client. Simply put, the user sends a command to the server, asking the server to send a file to the user. The server responds and sends the file to the client. The user receives the file and places it in the user's working directory. This process is carried out by the FTP server. How Does FTP Server Work? FTP is based on the TCP protocol service, which is a file transfer protocol on the Internet. By default, two ports 20 and 21 are used, a data port and a command port, and port 20 is a data port for file transfer between the client and the server data flow. Port 21 is a command port used to transmit control flow and accept related FTP commands and parameters issued by the client. The FTP client sends a service request to the FTP server in the computer network. The FTP server receives and responds to the FTP client's request and provides the FTP client with the required file transfer service. According to the provisions of the TCP protocol, FTP servers use well-known port numbers 20 and 21 to provide services, and FTP clients use temporary port numbers to send requests. The FTP protocol specifies different well-known port numbers for control connections and data connections, the well-known port number for control connections is 21, and the well-known port number for data connections is 20. The FTP protocol uses a continuous connection communication method, and the maintenance time of the control connection it establishes is usually long. After explaining the main connection method of the working principle of FTP, then explain the two types of data connection establishment in the working principle of FTP: active mode and passive mode. The active mode of FTP is that the client connects to the well-known port of the FTP server from any unprivileged port, that is, port 21. After receiving the command, the FTP server connects to another temporary port of the client from the data port and returns data; passive mode means that the client opens two arbitrary non-privileged ports to submit commands, and the FTP server passively opens any non-privileged ports to send commands to the client. After the client receives the command, it initiates a connection to the FTP server from the local port to establish a transmission data channel. In this mode, the command connection and the data connection are initiated by the client to solve the problem of the server initiating the connection to the client. Generally speaking, if we take the server as the criterion. Active mode: The server initiates a connection to the client from port 20. Passive mode: The server passively waits for a client to initiate a connection on a port within a specified range. The realization goal of FTP is to realize the safe sharing of file data, that is, the computer client can connect to the FTP servers around the world through the FTP client and the Internet to achieve file data sharing and resource sharing. Realize information interaction, that is, other computer clients can access the FTP server built on your computer through the Internet, so that your information can be spread to all parts of the world. Carry out effective data transmission. Files can be exchanged between computers of different types, different systems, and different formats. Do you know the FTP server now?

FTP) is a common protocol in the file transfer process. Many companies build FTP servers to provide file download services. Here are two transfer modes for FTP. FTP differs from other services in that it uses two ports and one data port. And a command port . Usually, port 21 is the command port and port 20 is the data port. When the concept of active/passive mode is mixed in, the data port may not be 20. Active Mode The working principle of the active mode: FTP client uses N port to connect to port 21 of the FTP server, sends a user name and password to log in, and after successful login to list or read data, the client opens the N+1 port. Send the PORT command to the FTP server, tell the server-client to adopt the active mode and open the port; After receiving the PORT active mode command and port number, the FTP server connects through the server's 20 port and the client's open port to send data. Passive Mode The working principle of the passive mode: the FTP client uses N to connect to port 21 of the FTP server, and sends a user name and password to log in. After successful login, if you want to list or read data, send a PASV command to the FTP server. Open a port locally , and then tell the client the open port. The client then connects to the open port of the server through the N+1 port for data transmission. Active Mode VS Passive Mode The difference between the two is that when establishing a data movement connection, the main mode connection initiator is server-side, and the port 20 connects to the client's N+1 port to establish the data connection; the passive mode connection initiator is the client, and the client uses Port number +1 to connect to a high-order part of the server. Differences IN Network Settings Scenario: The FTP client and server are on different networks, and a firewall is required between the two networks. The client's FTP software sets the port segment opened in active mode, and the corresponding port segment can be opened on the client's firewall. There is a common problem: only port 21 is opened on the server-side, and no port is opened on the client machine. The passive mode adopted by the FTP client connection results in that the client can log in successfully, but cannot list and read data. It is because the server does not open the random port in passive mode. In passive mode, the open ports on the server-side are random, but the firewall must not be fully open. The solution is to open some random high-level ports in the passive mode of the FTP server configuration , and then set the rules in the firewall, open the corresponding port number on the server-side.

What is FTP? FTP is an unencrypted file transfer protocol, meaning that it sends data, usernames, and passwords in plaintext. In the ‘70s and ‘80s, when employees were transferring files behind firewalls, this wasn’t an issue. In the past 40 years, file transfers have changed and cybercriminals have become more sophisticated. Confidential files are sent outside companies’ firewalls and can be read if they’re sent with FTP. To avoid these security issues, companies choose SFTP, FTPS, or HTTPS to transfer files. Corporations and other entities have daily requirements for file sharing, both within their organizations and among their larger external networks. These requirements are compounded by the need to demonstrate compliance with various industry mandates, such as HIPAA, SOX, the GDPR, and PCI DSS. The good news is there are secure FTP solutions that are more effective alternatives to transferring files that help to avoid the many risks associated with FTP. 1.HTTPS Hypertext Transfer Protocol Secure adds security to HTTP by offering certificate authentication. Additionally, it encrypts a website’s inbound traffic and introduces an encryption layer via TLS to ensures data integrity and privacy. HTTPS protects a web visitor’s identity and secures account details, payments, and other transactions involving sensitive details. When it comes to transferring files, this protocol enables the use of a simple but secure interface for uploading data from business partners or customers. 2.FTPS Often mistaken with SFTP, FTPS is an extension to FTP. FTPS adds support for Transport Layer Security encryption, which was formerly known as SSL. TLS uses public and private keys to encrypt communications. The public key is available to everyone who requests information from the server and it encrypts information before transfer. The private key is only available to the owner of the server and it decrypts information after transfer. 3.SFTP SFTP is an encrypted protocol that uses Secure Shell or SSH. SSH works by creating an encrypted connection between a client and a server. Companies prefer SFTP because it requires credentials before the user is allowed to connect to an SFTP client. SFTP often used for business trading partners to share information as it’s platform-independent and firewall-friendly, only requiring one port number to initiate a session and transfer information. 4.Managed File Transfer Managed file transfer  secures and simplifies the process of exchanging files. MFT lets businesses replace FTP servers and continue using secure protocols. A managed file transfer solution supports each of the secure FTP solution options listed above for secure data transmissions among internal users and external entities. This method includes an extensive list of security features that make it an ideal choice for meeting the stringent guidelines of many industry regulations. Raysync – A Perfect FTP Alternative Managed File Transfer Solution Raysync’s high-speed transfer protocol is a core transfer technology developed by Shenzhen Yunyu Technology Co., Ltd. based on the UDP transfer protocol.

Transport Layer: A Black Tech that Overthrows the TCP Protocol The TCP transfer protocol does provide a reliable data transfer under ideal conditions, but with its fixed throughput bottleneck, a prominent and serious condition would occur due to high packet loss and latency caused by a long-distance network transfer. Raysync guarantees reliability in the application layer with an innovative method that eliminates drawbacks such as low efficiency in TCP, packet loss, processing errors, and unstable transfer rate. To ensure 100% reliability, Raysync adopts the best mechanism that accurately identifies and passes on the actual packet loss condition on the transfer channel. Application Layer: Best Alternative to FTP The FTP transfer protocol has been used for more than 40 years, but it is also a fact that the efficiency of FTP file transfer has been far less than the growth rate of data in the face of today's complex file exchange requirements. FTP is even worse in the file management tasks that enterprises urgently need today. In order to transfer files while maintaining security through FTP, this requires complex scripts, continuous maintenance, and even other applications to assist. All of which may cause time and money losses to enterprises by varying degrees. Basing upon UDP’s high-speed transfer protocol, Raysync breaks through the bottleneck of large file transfer which satisfies enterprises’ needs by building an intelligent transfer platform that processes and integrates massive data at an unprecedented speed.

Long before users might use the protocol to maneuver knowledge on the net, File Transfer Protocol was developed as a complete technology that allowed users to maneuver knowledge from one location to a different. The FTP specification was written in 1971, before the appearance of the web. Although thought-about a mature and noncurrent technology, FTP remains wide used nowadays quite forty years later. Five facts about FTP 1. The transferred file isn't encrypted, that is less complicated to be intercepted by FTP 2. FTP lacks visibility and can't offer insight if the file transfer fails or is interrupted 3. sophisticated or large-capacity file transfer advancement can't be machine-driven through FTP 4. FTP lacks functions to push compliance needs 5. in keeping with the Federal Bureau of Investigation, FTP is liable to hacker attacks FTP, file transfer protocol, or file transfer problem? When alternative ways don't work or don't seem to be on the market, organizations sometimes started FTP servers to exchange info. In some cases, the file size exceeds the e-mail capability. In alternative cases, there are square measure security problems. FTP was once thought about as the most effective thanks to transferring files. it's convenient, straightforward to use, and safe. But now, this can be not the case. Nowadays, FTP is typically deployed briefly to fulfill application needs or solve specific issues. However, once victimization FTP during this means, there's no centralized tool on the market . As a result, it'll not be ready to safely or expeditiously manage or management its surroundings. Being restricted by no visibility, no control, and no security square measure major challenges facing organizations that use FTP. Ignoring any of those 3 might compromise the safety of their knowledge and IT infrastructure. There is nothing wrong with FTP itself, as long because it meets your needs. However, once your organization desires a strong platform to assist you to meet multiple desires, FTP isn't enough. after you manage an outsized range of file transfers or advanced file transfer workflows and file transfer compliance may be a priority, a hosted file transfer platform is that the best answer to fulfill your business desires. With the Managed File Transfer platform, you'll be able to safely and expeditiously manage all the file transfer complexness and security needs applicable to today's trendy organizations. 1.

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. 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 that are vulnerable to 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 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 A directory traversal attack exploits insufficient security validation or sanitization of user-supplied file names, such that characters representing "traverse to parent directory" are passed through to the operating system's file system API. 3. Cross-site scripting Cross-site scripting is a type of security vulnerability that can be found in some web applications. XSS attacks enable attackers to inject client-side scripts into web pages viewed by other users. A cross-site scripting vulnerability may be used by attackers to bypass access controls such as the same-origin policy. 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, managed file transfer 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 - The global visibility of all data transfer 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 - Data Synchronization Supports two-way file synchronization that maintains the consistency of data across multiple devices, ensuring no redundant fragmented files are produced and multi-point data sync is efficient. - Point-to-point Transfer Adopts user ID to achieve point-to-point transfer, eliminating intermediate transfer for rapid file-sharing. - Standard Bank-Level Encryption Technology With the AES-256+SSL+Random salt high-density encryption algorithm, even the developers are unable to recover the root password through the stored ciphertext, making sure the data security is worry-free. - Audit trails Uses transfer logs and operations logs to supervise user behavior, easily trace all operations and file content, effectively control improper usage behavior and help enterprises to achieve better file management. - User-defined Management User-defined management perfectly plots out the organizational structure, supporting group management by defining regions, departments, and role-based permissions that set authority to standardize enterprise users' operation. - Intelligence Nodes Management With intelligence nodes management equipped, it supports unified management of all node machines in both the internal and external network environment to monitor and collect all operation logs and data synchronously. - Hybrid Cloud Storage Raysync supports more than 10 mainstream storage methods including hybrid storage effectively assisting enterprises to store, backup, migrate and synchronize their files in an orderly manner. As a one-stop solution provider, Raysync has independently developed its core transfer technology with its professional technical teams to offer high-performance, secure, and reliable large file transfer and file management services for major enterprises.

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. File Transfer Protocol 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 . 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  is an extension to the commonly used File Transfer Protocol that adds support for the Transport Layer Security and the Secure Sockets Layer cryptographic protocols. SFTP  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 file transfer 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.
