The complete transfer process of data includes data generation, data transfer, and data reception. Cross-border data transfer is a bridge connecting the place where data is generated and the place where it is received, but the dilemma of data transfer is also derived from this part. Low efficiency of cross-border data transfer The branches of enterprises are scattered around the world, the headquarters of enterprises need to closely communicate with their branches so that the tasks can be finished efficiently. With the increasing amount of data, traditional network transfer methods such as FTP can hardly ensure the efficiency of cross-border transfer of large files, which seriously affects the project delivery schedule. Unstable cross-border data transfer leads to data damage or loss Cross-border transfer may face the problems of excessive transfer distance and poor network environment. Uploading and downloading data may be interrupted, and enterprises sometimes have to arrange special personnel to monitor data transfer. Even in this way, it is impossible to prevent the transfer data from being damaged. Unsafe transfer methods may also cause data damage or loss in the process of transfer. Many industries have very high requirements for data confidentiality, and data is maliciously stolen during cross-border transfer, which will eventually bring immeasurable losses to enterprises. Shenzhen Yunyu Technology Co., Ltd., as one of the leading manufacturers of enterprise big data exchange, perfectly solves the problems encountered in the process of transnational, long-distance, large files and massive files transfer by virtue of its self-developed data transfer core technology-Raysync transfer engine: Optimize transfer performance and efficiently transfer data across borders Raysync breakpoint resume function ensures that after the system is launched again, the remaining materials can be downloaded from the recording position .

Enterprise-level security encryption to avoid copyright infringement Raysync has many types of data encryption schemes, which form an encryption tunnel between the sending and receiving ends of data to ensure that data will not be stolen or leaked in the process of transnational transfer and avoid the loss of enterprises. Facilitate business management via centralized authority control Raysync records the complete behavior logs of users such as login, logout, upload, download, and links sharing. Auditors can regularly audit the operation behaviors of members, and guard against the occurrence of malicious data leakage.

The trade industry refers to a group of trading entities characterized by specialized operations formed by commodity producers and commodity operators whose main business types and scopes are basically the same. The industry consists of eight categories including pure trading industry, distribution industry in enterprises, securities circulation industry, information-based circulation industry, pharmacy industry, water, electricity, air distribution industry, catering service industry, and logistics industry. Therefore, industry information is the core principle of trade. In the business model of the trade industry, the core purpose is to earn more profit margins. Usually, revenue, costs, expenses, and profits are calculated on a single basis, and payments are strictly controlled according to budget during the execution of the business. Therefore, the trade industry has higher requirements for enterprise risk control and stricter requirements on timeliness. In the trading industry market environment, the core competitiveness of an enterprise is determined by the level of informatization. It has a sufficiently broad information resource library, can obtain and process information faster than its opponents, quickly configure various resources of the enterprise on-demand, and respond to market demands in real-time. In an invincible place. Enterprises in the trade industry have implemented information systems in daily office, business operations, customer management, etc., but document management is still in a relatively backward state, business data cannot be managed and coordinated in a unified manner, management personnel cannot fully grasp the transaction progress in real-time, and a lot of internal and external cooperation Difficulties in document archiving and searching, and the loss of historical transaction data have seriously affected the business continuity of trading companies. The file management of trading companies is facing pain points in the following scenarios: 1. The industry trade area is easy to overlap, and the data leakage is serious. The salesman has mastered the company's customer resources for several years to accumulate the information industry, and can quickly establish itself, which has an impact on the original enterprise. 2. Data or files exchange uses QQ, WeChat, and email, involving many partners. Project data transmission is frequent but inefficient, resource information is not synchronized in time, and data cannot be managed in a unified manner. 3. For large-scale trade projects, if multi-departmental and multi-company cooperation is involved, the specific progress in the transaction process cannot be fed back in time, and the company management is prone to management blind spots. 4. A large amount of information generated during the entire transaction process is scattered and stored and faces hidden dangers of insecurity. Loss and leakage may cause major losses to the enterprise. 5. Communicate with overseas customers, and send design renderings, processing and production drawings, and other documents through email. The transmission speed is slow and large files cannot be sent, which reduces communication efficiency. In the face of such pain points, Raysync Cloud builds a cross-border cloud storage file transfer management platform for trading companies to help the trading industry archive project materials, reduce communication costs, and improve internal/external work efficiency, thereby reducing transaction cycles and responding to the market in real-time According to demand, various resources of the enterprise can be quickly allocated according to needs, and finally take the lead in the fierce market competition.

In the daily surfing life on the Internet, people often overlook a problem. When we use peer-to-peer software to access multiple media files, such as books, music, movies, or games, the danger is also closely followed. Peer-to-peer file sharing is the use of peer-to-peer network technology to distribute and share digital media. Take BitTorrent, a popular file-sharing protocol, as an example. It was created by Bram Cohen for P2P file sharing and is a P2P file transfer protocol based on TCP/IP protocol. P2P file-sharing has many uses, especially among enterprises. But the reality is that the file-sharing protocol BitTorrent is a controversial subject in the security world. Especially, BitTorrent enjoys a "high reputation" in piracy when copyright protection and illegal content are shared equally. It is estimated that nearly one quarter of Internet traffic infringes copyright. In 2017, the most popular BitTorrent index on almost all the top 50 most popular search phrases is the name of copyright movie or TV program. If users want to use VPN to access P2P file sharing sites, they may want to access illegal content anonymously. If they download illegal content, they are not only responsible for copyright issues, but they can easily download dangerous malicious software without realizing it at all. Although the danger may not be as common as other areas on the Internet, malicious software can still be inadvertently obtained through P2P file sharing. Remember this unfortunate user who stole more than four bitcoins from his computer after downloading pirated video games infected with malicious software? This risk is still very real. According to ZDNet, P2P file sharing websites infect millions of users every month. Raysync is dedicated to ensuring the fast file transfer, while protecting the data security. Raysync provides multiple modes of transfer according to different transfer initiators. It supports the peer-to-peer, multi-point mutual transfer, one-to-many data distribution, and other modes. It also provides exclusive user and user group space, supports specific authority management, and build exclusive assistance space and file sharing requirements across departments and companies.

E-mail is still the most popular attack medium. Legitimate e-mails are attacked during transmission and hijacked in complicated ways, while phishing emails try to deceive people with fake addresses, which is a typical phishing attack . How to respond to the chain attach via email? Virus software purchases an email account through the email response chain. Attackers use phishing, violence or social engineering to access one or more email accounts, and then start to observe the conversation, and seek opportunities to send malicious software or malicious links to one or more participants in the ongoing communication chain. What types of malware use response chains as attack vectors? In 2017, the attack on the email response chain was first discovered. In 2018, Gozi ISFB/Ursnif Banking Trojan horse activities also began to use this technology; In other cases, attackers break legal accounts and use them to take over existing threads and spam attacks on other recipients. Malicious attachments can use VBScript and PowerShell to transfer workloads, such as emote, Ursnif, and other loaders or bank trojan malware. Ordinary fraudulent emails are usually sent in the form of topics or short messages, which are easy to identify and have less chance of being deceived. However, attacks through e-mail response chains are often carefully considered, without grammatical errors and with clear semantics. This means that even the most cautious and well-trained employees may become victims. Four methods to prevent email response chain attack Since the response chain attack is based on account compromise, it should be ensured that all employees of the company follow the verified security procedures. These include two-factor or multi-factor authentication, with a password set for each account. Secondly, the use of Office macros should be restricted or completely prohibited as much as possible. Although these are not the only means by which malicious attachments may endanger devices, macros are still common attack vectors. Introducing safety awareness training is of great help to train employees to understand the dangers of phishing. E-mail users need to raise people's awareness of phishing attacks and how attackers develop their technologies. Information assets are very valuable for enterprises, so it is better to deploy a data transfer solution as soon as possible instead of preventing this and that. Raysync adopts self-developed transfer protocol, which can help enterprises to quickly distribute large files or massive small files, and can provide the highest transfer speed with minimum system overhead regardless of the distance of transfer or the strength of network conditions; Security is also the focus of Raysync. The whole process of file transfer adopts financial AES-256 encryption transfer to ensure data security. The mechanism of breakpoint continuous transfer and error automatic retransfer ensures that the transfer can continue from the breakpoint after unexpected interruption of transfer, ensuring the integrity and reliability of file transfer, and monitoring the whole process log to ensure considerable, searchable and traceable data.

For decades, there has been no good solution for enterprises to balance security and productivity in file sharing. Especially in this fast-paced era, people are not satisfied with traditional disk movement, FTP, and email to complete file sharing. People want to work collaboratively anytime and anywhere, so more and more people are turning to file sharing solutions. However, it is worrying that according to the research report, 50% of enterprises have no policy on file-sharing tools. Even if there is a policy, 48% said they would not implement it. More importantly, 69% of small and medium-sized enterprises don't even know whether their employees are using unapproved file-sharing tools or dangerous file-sharing tools. How to strike a balance between employee productivity and protecting critical data? Many employees of enterprises are already using file-sharing software. As mentioned above, this may expose the data of enterprises to the risk of data leakage because of IT compliance. Perhaps it is not intentional for people to leave the company with sensitive documents when they move , but the risks always exist. Instead of letting employees look for various file-sharing tools spontaneously, it is better to integrate a compliant and controllable file sharing tool into the existing office software of enterprises to create a safe and comfortable office environment. This file sharing tool needs to meet the following characteristics: - Improves the employee productivity - Easy to use - Security, data sharing process security and storage security - Compliance-meet the strict compliance requirements of the industry - Good integration Raysync - the fastest and most secure file sharing tool - Raysync has a self-developed high-speed transfer protocol, and the bandwidth utilization rate is over 96%.
