In this era of big data, it is common for individuals or enterprise groups to violate their private information or confidential documents and even make profits. Especially in recent years, with the development of new-generation information technologies such as cloud computing, big data, and mobile internet, the types and quantities of data are becoming larger and larger, and the data compliance requirements in China are becoming stricter. With the promotion of the Network Security Law, the compliance of data local storage and cross-border transmission has become the focus of attention.
The awareness of data security of individuals and enterprises is constantly increasing, and the file storage and transmission technology are also developing towards standardization, standardization, and compliance. With reference to the requirements of relevant laws and regulations, relevant product technical standards are formulated, and data security technology products meeting the corresponding technical standards are applied. In the future, data transmission compliance will become a major trend in the future big data industry.
Raysync fully responds to the call of national data transmission compliance, and improves the security of file transmission from the aspects of Web security office design, account & password protection security design, transmission security design, software installation & operation security design, behavior audit, encryption certificate life cycle management, etc., providing users with a high-speed, safe and convenient file acceleration transmission platform!
WEB security design:
User-side Web Portal and management-side Web Portal support access IP address isolation and port isolation; The administrator can disable the user plane Web Portal or the management plane web portal as required. Support Http and Https, the administrator can disable Http and only provide Https service; The Web page of to login Raysync, the effective range of session is only valid for the current access page, completely eliminating CSRF cross-site attack; Before each version is released, Huawei Cloud Online Professional Web Vulnerability Scanning Service is used to scan vulnerabilities and repair the latest released vulnerabilities in time; Https TLS only opens the encryption algorithm suite that is recognized as safe in the industry.
Account protection security design:
Login authentication has a built-in anti-violence cracking mechanism, and the user enters the wrong password five times in a row within 3 minutes, and the account will be automatically locked; Session identification in login is generated by using the interface of OpenSSL high-strength random function RAND_bytes to prevent random information from being hit by the simulator.
Transmission security design:
In the transmission process, Raysync is protected by Hash verification at the transmission message level, file block, and the whole file to ensure the integrity of the transmission content; TLS 1.3 is used for end-to-end encryption between the Raysync client and the Raysync server to prevent man-in-the-middle attacks on the network. Raysynconly needs to expose one port to the outside, which can meet all users' access and greatly reduce the risk of firewall port exposure.
Raysync relies on a self-developed transmission protocol to help enterprises solve the problems of large file transmission, massive small file transmission, and cross-border file transmission, without fear of the influence of transmission distance and network environment, and maintain a stable, efficient, and safe high-standard transmission level.

Before choosing a secure file transfer solution for an enterprise, it is best to have a basic understanding of the transfer protocols involved:
1.FTP
FTP is a very primitive file transfer protocol, which has been popular for decades. FTP uses two separate channels to exchange data, "command channel" to verify user identity and "data channel" to transmit files, but both channels are unencrypted, and any data sent on the channels can be easily utilized.
2. FTPS
FTPS is a secure file transfer protocol, which allows you to securely transfer files with your trading partners and customers. File transfer can be authenticated by methods supported by FTPS, such as client certificate, server certificate, and password.
3. SFTP
SFTP stands for FTP over SSH . It is a secure FTP protocol and a good alternative to insecure FTP tools. SFTP exchanges data through SSH connection, and provides organizations with high protection for file transfer shared among their systems, trading partners, employees, and the cloud.
4. http&HTTPS
Http is the basis of data communication. It defines the message format of communication between the Web browser and Web server and defines how Web browser should respond to Web requests. HTTP uses TCP transfer control protocol as the underlying transmission, which is a stateless protocol, which means that each command is executed independently, and the receiver does not keep the session information.
Https is a secure version of HTTP, in which communication is encrypted by TLS or SSL.
5. AS2, AS3, and AS4
AS2, AS3, and AS4 are popular protocols used to send and protect key file transfers.
AS2 is used to transmit sensitive data safely and reliably on the network. AS2 uses digital certificates and encryption standards to protect key information transmitted between systems, networks, and locations. AS2 messages can be compressed, signed, encrypted, and sent through a secure SSL tunnel.
AS3 is a standard that can be used to transfer almost any file type. It provides security protection for data transmission through digital signature and data encryption. Originally, AS3 was created for transmitting data files, such as XML and EDI business-to-enterprise data files. Unlike AS2, AS2 is a defined transport protocol, and AS3 is a message standard, which focuses on how to format messages when sending from server to server. Once the AS3 message is synthesized, it can be transmitted through any other protocol .
AS4 is a protocol that allows enterprises to exchange data securely with their partners. Its predecessor was AS2, but it improved delivery notice based on AS2. As a business-to-business standard, AS4 makes it safe and simple to exchange files online.
6. MFT Managed File Transfer Protocol
MFT integrates the advantages of these protocols to help users solve various file transfer problems and improve enterprise efficiency.

Case study: An intelligent technology company urgently needs to transfer 8TB of R&D data to the Swiss branch, and there is no urgent need for big data transfer at ordinary times.
Customer demand analysis:
1. "Urgent" demand: R&D data needs to be distributed to the Swiss branch as soon as possible and put into production immediately. If you mail the hard disk or the traditional FTP transfer method, you can't meet the customer's demand for the timely delivery of the data.
2. Cost control requirements: The companies’ big data transfer has the characteristics of low frequency. The company has not set enough budget for the big data transfer project. After understanding the data transfer solutions in the market, it is found that a set of software needs to cost hundreds of thousands, which will cause serious waste of resources and financial resources, which is inconsistent with the needs of the company.
3. Flexible requirements: Just like the urgent transfer of 8TB files to Switzerland this time, we can't predict whether the next large file transfer task will also be affected by unexpected factors, that is, the transfer software pay-as-you-go plan is the best choice for enterprises.
4. Data security requirements: Production R&D data is the lifeblood of enterprise production and operation, and its importance is self-evident. In the process of transfer, due to poor network environment and long transfer distance, it may lead to low transfer efficiency, and file transfer security loopholes are more likely to occur. The leakage of R&D data will bring a devastating blow to enterprises. Considering the need to transmit enterprise R&D data overseas, the company has high requirements for the security of the transfer process.
5. Requirements for easy-to-use: The company's big data transfer frequency is low, the interface is simple, the operation is simple, and the convenient and fast transfer software is deployed, which will greatly reduce the time cost for employees to learn to use the software, and the work of data uploading and downloading will get started faster.
The Raysync server is deployed at the Nanjing headquarters of the company, and the team members of the Swiss branch can log in to Raysync through IP address and port number, so as to easily upload and download the production R&D data.
Compared with the traditional FTP transfer, the timeliness of Raysync transfer is improved by 96%.

File Transfer Protocol provides a simple way for users to send files and information ad hoc from one location to another. FTP provides a medium for establishing communication between computers for file transfer. Although it is still a widely used and well-known file transfer method, people have many misconceptions about FTP. The following are some of the most common misconceptions:
Misconception 1: FTP encrypts data as it’s transferred.
FTP doesn't encrypted the data in the process of transferring. When FTP is used, all transmissions are transmitted in clear text, which means that if the transmission is intercepted, the data can be easily obtained. Data leakage occurs when users send sensitive data through unsafe sites or anonymous FTP sites.
Using FTP to transfer business data means sacrificing data security. In addition, enterprises or organizations install FTP servers for some reason, but they usually forget the existence of FTP, do not update it, and have little supervision over the data stored on it.
Misconception 2: All that matters is getting data from point A to point B.
In addition to ensuring that files go from one location to another, you need to work hard to prove compliance with data protection regulations. FTP is developed only for transferring files, and does not provide any functions to support security and compliance requirements. If you have any sensitive or regulated data to transmit, choosing FTP will expose these important data to danger.
Misconception 3: Homegrown FTP is good enough
If you use the local FTP system, you may encounter problems and face many risks. Data silos may pose various challenges to employees who need timely access to data to make data-driven business decisions. You may also find that you spend more time logging in to various systems and platforms, troubleshooting or performing other related maintenance tasks.
Using distributed file transfer systems also makes it more difficult to manage compliance. IT is time-consuming and error-prone to audit various applications and systems without a comprehensive understanding of IT systems.
From FTP to MFT
Managed file transfer technologies provide multi-layered security and compliance supporting capabilities, far beyond the more basic file transfer mechanisms like FTP. MFT technology’s features include in-depth reporting , global visibility into your data at all times, end-to-end security with encryption of data in transit and at rest, performance metrics/monitoring to meet stringent SLAs and compliance mandates, and the automation of file transfer-related processes. If you are looking for a stable and secure file transfer software, Raysync is definitely your best choice!
