What's Shadow IT? Gartner analyst Simon Mingay wrote in a research report that Shadow IT in a broad sense includes "investment in the acquisition, development and/or operation of IT solutions outside the formal control of formal IT organizations". To put IT simply, Shadow IT refers to a department or individual who uses IT-related hardware or software without knowing the IT or security group in the organization. In reality, employees in general enterprises rely on software that has not been approved by IT departments. Business departments bypass IT departments and use applications on the cloud to complete their work efficiently and quickly. These are also called "shadow IT". Although "shadow IT" and "business value" doesn't sound directly related, using shadow IT is quite simple and direct. But when shadow IT was exposed, IT revealed many security vulnerabilities to IT departments. Enterprise employees can easily bypass the IT team's approval, but they cannot check the reliability and security of the selected application in depth. Employees unconsciously input important enterprise data into unauthorized cloud services, which makes enterprise data security a gamble directly. In fact, nearly 80% of employees in general enterprises rely on this software that has not been approved by IT departments. Faced with this situation, what should IT leaders do if they find that these unsafe applications are being used by employees or are sharing sensitive information? It's obvious that it's natural to react quickly and demand that these applications be stopped immediately and that employees who violate the company's data security regulations be punished. However, the value gained by IT leaders from the discovery of Shadow IT is equally important for future IT decisions. What is the problem with Shadow IT? If IT executives find that employees are using free file sharing applications, the next step is to find out why employees use them. For what reason do so many employees bypass FTP and other systems and secretly use these applications for file sharing? Only by breaking the root cause of Shadow IT entering the enterprise can we improve the current situation of the enterprise and truly protect the data security of the enterprise. It's easy to find out that many employees express their weakness in the processing efficiency of existing enterprise application systems. FTP is time-consuming and complex, and email is limited by attachment volume, so professional software procurement costs are high. The huge amount of data and the impatient urging of customers make them need a fast way to transfer files. Although the situation of each enterprise is different, fundamentally, the biggest reason for employees to use these file transfer software is that they can handle their work at any time and anywhere with a low cost or even zero cost. Breaking Shadow IT and Solving Enterprise Application Compliance Problems Recognizing the above problems, we will find that it is not enough to order employees to stop using unsafe file sharing applications. No matter how hard IT leaders try to control the organization's data, employees can choose unsafe solutions. Enterprises can choose compliance solutions such as Raysync. The goal of Raysync is to help enterprises and IT departments solve the normative problems of file sharing and provide easy-to-use and high-speed file transmission solutions for enterprise employees to improve office efficiency. Enterprises using Raysync software can use account management to help control file flow, and the high-speed transfer engine independently developed by Raysync can meet the extreme speed transfer of TB-level large files and massive small files. Raysync is flexible enough to meet the various demands of enterprises. At this stage, Raysync introduces the flow version, which can be purchased by enterprises according to their needs. Enjoy the file transfer service of Raysync professional version at low cost, effectively control the cost consumption, eliminate the waste of resources, and realize the cost optimization. It provides a one-stop enterprise-level large file transfer solution, and it is an efficient way to obtain policy cooperation between employees and companies.

With the vigorous development of new technologies such as cloud computing, big data, the Internet of Things, and artificial intelligence, large-scale new applications have facilitated my life. But at the same time, hackers, who are tempted by the interests of black products, also turn their eyes to this place, and they have targeted attacks, again and again, thus directly plundering enterprise data resources and important customers. Here are our 5 tips for improving your data security: 1. Troubleshoot computer network system vulnerabilities The computer network system is composed of computer hardware, software, and client network system configuration. The first step of enterprise self-examination is to carry out daily maintenance of its own hardware equipment; Secondly, it is also the key point to check the compliance and security of software systems, clean up the non-compliant and unsafe third-party applications used by employees in time, update the conventional systems, and investigate loopholes; The other is to configure the client's network system safely. 2. Is the data using standardized The second point of self-examination of enterprise data security is to standardize the management of enterprise data use. Enterprises have a clear positioning of safety standards, and the practicality of specific data usage specifications is usually reflected in employees' daily work. Especially in file transmission, the transmission process is the hardest hit by network attacks, and the control of data flow is also very important. Just as many Internet companies are doing, it is necessary to manage the access, editing, and downloading rights of sensitive data, which plays a protective role in data security to a certain extent. 3. Investigate employees' safety awareness At present, nearly half of cyber-attacks are caused by the lack of security awareness of enterprise employees, which directly or indirectly leads to data leakage. The employees' awareness of the importance of data and network attack methods is directly related to their sensitivity to the possible security threats and potential attacks of current data. Many enterprises tend to ignore the safety control of employees. Do your employees really know what might be a cyber attack? Data security training is a good way for employees' safety awareness. Establish a culture so that employees can quickly perceive potential threats and report suspicious cases in time. The above self-inspection method is based on three key factors of data security, and the other two points we want to mention are the self-inspection method of security control of dynamic data. 4. Data flow direction "High-speed data transfer creates value for enterprises" is the service concept of Raysync. On the contrary, this sentence is essentially the normal state of enterprise business transfer. Every day, a small and medium-sized enterprise produces no less than 10GB of data, and where this data flow is actually a security blind spot for many enterprises. At present, there are more and more ways of online data interaction, and various ways of data interaction facilitate people's work, but also greatly increase the difficulty for enterprises to supervise data security. To solve this problem, let's take a look at how the enterprise-level file transfer expert Raysync deals with it. - Transmission management and control: add transmission strategy, transmission reality, and transmission log design, and the administrator can take a glance at the transmission of sub-accounts; - Supervision of document outgoing: all documents outgoing are under management supervision. In the face of sensitive data leakage, the administrator can directly interrupt the sharing of relevant documents; 5. Grade authority Dividing data grades and employee categories is the key to building an enterprise data safety net. Hackers and system vulnerabilities are the main reasons for data leakage incidents. Some conscious and unconscious operation behaviors of employees in their daily work are easily manipulated or misled by cybercriminals, and the data level they come into contact with is the height of enterprise information assets that criminals can reach. Grant local administrative authority only when necessary, assuming that the network attack against the enterprise is successful , and the infected computer cannot easily spread malicious software to other devices in the network, which plays an important role in curbing the attack scope. In view of this, many applications can do it at present. For example, several functional designs of data authority such as identity authorization, user grouping, and security encryption in Raysync run through the whole process of data security transmission, which is a good way to protect enterprise data security. Data flow transfers data to create greater value. Today, with the rapid development of science and technology, the process of data interaction is both an opportunity and a challenge for Internet enterprises, as well as hackers.

Data transfer has played an important role for enterprises to conduct business with its customers, partners and suppliers while acting as its foundation in mining data value. However, the emergence of the Big Data era has spawned a massive amount of data, while various data types and interactive scenarios have become increasingly complex, the efficiency and security of data transfer is also facing its challenges. If enterprises desire to continue extract value and create opportunities, the foremost priority is to tackle data transfer. Challenges: Large File Transfer ● While the amount of data has skyrocketed, the transfer efficiency is still poor; ● Data types are diverse and traditional transferring methods are difficult to guarantee its integrity; ● Network environment is complex while the cases of data loss and leakage are increasing; ● Cross-regional and long-distance teamwork has increased, but high latency and high packet loss rate have also become prominent. The key to solving the challenges above is to find a first-class data transfer engine. This would eminently support enterprises to build a high-speed, secure, and stable environment for data transfer, which brings an edge to lead in a data-driven development. The Great TCP Bottleneck Transfer protocol is the foundation beneath every data transfer, in which TCP is the most commonly used IP transport layer protocol. Compared to other protocols, TCP is able to provide a more reliable service for establishing connections between specific network systems and applications. Originally developed in the early 1970s when networks were still local and data files were small, TCP served as the basic protocol which enabled data to move efficiently and reliably within the local area network with very small bandwidth. To maintain this reliability, TCP ensures that the application data transmitted in a single TCP connection arrives at the receiver’s application in the same sequence as when it was sent. Therefore, TCP uses an algorithm to establish the connection between the sender and receiver, creating transfer requests in turn, and splitting the data into packets, which are then sent separately through the network without the need for acknowledgement until reaching its definition limit. . The sliding window protocol is used by TCP to define the data buffer. Figure 1 below is a simplified diagram that demonstrates how TCP sends out small packets over the network and how TCP windowing controls how much data can be transmitted without acknowledgement. As the packets are delayed, TCP will then slow down the transfer rate with a smaller window size, which further limits the number of unacknowledged packets allowed. TCP algorithm is proved to be effective when data transfer occurs over a short distance while the network is not congested. However, when the round trip time of packet transfer is inevitably increased by distance, both the performance and efficiency shall be affected. Especially under the scenarios of long-distance, transnational transfer, the transfer of large files and massive small files will expose the drawbacks of TCP protocol: ● Low transfer efficiency, end-to-end transfer requires sequence acknowledgement, the data processing is slow; ● Increase of data loss rate and latency when large files are transmitted; ● Extreme congestion control throttling which results in unnatural throughput loss; ● TCP cannot guarantee its reliability, its file check mechanism is imperfect. In essence, TCP cannot be defined as a reliable transfer in the true sense of the word. Especially under the pressure of data volume and distant transfer, TCP is unable to guarantee the efficiency of transfer and yet it may expose enterprises to data security threats. Raysync – A Brand New Transfer Protocol Raysync’s high-speed transfer protocol is a core transfer technology developed by Shenzhen Yunyu Technology Co., Ltd. based on the UDP transfer protocol. This breakthrough technology does not simply optimize or accelerate data transfer but it takes a leap forward in the transfer technology to completely eliminate the underlying bottleneck while overcoming the limitations of traditional network and hardware. Raysync is able to fully make use of network bandwidth thus provides an ultra-low latency, high speed and end-to-end output service. The transmission rate can be increased by nearly 100 times, achieving over 96% of bandwidth utilization rate while easily adhering to the security, controllability and stability requirements for TB-level large files and massive small files transfer. 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 satisfy enterprises’ needs by building an intelligent transfer platform that processes and integrates massive data at an unprecedented speed. Fast, Secure and Reliable Large File Transfer System With its high-speed transfer protocol, Raysync provides all-around support for enterprises in large file interactions and cross-platform cooperation, achieving standardization within and between enterprises. Raysync’s intelligent data compression and intermittent transfer technology can also effectively reduce the network load, providing breakpoint resume and data verification to ensure stable and reliable data transfer. The intelligent management system is able to meet the business requirements of enterprises such as data interaction, sync and backup. Raysync makes sure to quickly integrate itself into existing OA, ERP and other enterprise systems, thus effectively reducing R&D costs to achieve data file linkage between business systems and operating system platforms, avoiding data islands. While Raysync has been continuously improving its file transfer acceleration technology, it also embraces the objectives of solving enterprise file transfer management into its scope of service to a full extent, building a smart file transfer system: ● 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 are 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 transmission 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 to assist enterprises to store, backup, migrate and synchronize their files in an orderly manner.

Introduction A peer-to-peer connection in telecommunications relates to a communication between two terminals or nodes. Peer-to-peer is shortened to P2P sometimes. In sharing platforms or in other data-sharing protocols between people, this use of P2P is separate from the use of P2P which means peer-to-peer. For instance, a telephone call when one phone is connected to another, and only the others could hear what one caller says. In contrast, this is a topology for point-to-multipoint or broadcast communication, where several nodes can receive information from a node. Additional instances of peer-to-peer links include leased lines, microwave relays, and two-way radio. For example, radio and television broadcasts are points-to-multiple. Have you used P2P? P2P transfer is now widely used to share files by many enterprises in their work after LAN, FTP, and HTTP are outdated. P2P transfer, known as peer-to-peer transfer, is an instant file transfer mode, which aimed to enable all clients to provide resources, including bandwidth, storage space, and computing capacity. P2P transfer technology has wide application scenarios, such as audio, video, and data sharing in various formats. How does P2P technology transfer files instantly? Why P2P transfer is accepted widely by many enterprises? In this article, let’s start with these two questions and explore the answers to peer-to-peer transfer. Everything about P2P Transfer in One Picture With the growing number of IP cores combined on one chip, the system-on-chip architecture is able to deploy complicated applications. The enormous need for communication and the ample computing capability on the chip put a considerable burden on the architecture in communication. Scalable communication architectures are therefore needed to implement future systems efficiently. Two types of communication systems, namely peer-to-peer and bus-based designs have traditionally been explored. At the expense of the specific channels between all communicating IP pairs, P2P communication designs can provide the most communication performance. However, in terms of high complexity, expense, and design effort these designs are poorly scalable. By contrast, bus systems can connect a few dozen IP cores economically and eliminate the complexity of the system and the specific cables required by P2P systems. The traditional HTTP transfer is to copy data to the client via server, thus the transfer speed is restricted by the bandwidth. Especially in today's network environment, the large amount of clients connects to one server, the bandwidth of servers will be shared, and the bandwidth of clients is difficult to be fully utilized, resulting in low efficiency of overall data transfer. In general data transfer, client A and client B is essential to build a connection to the server, and then data will be transfer through the channel built by the server and data recipient. P2P transfer technology builds the direct channel between client A and client B, shorten the original upload-download "1+1" time to 1; Secondly, "client A-server-client b" is turned to "client A-client b", which does not transit through the server and does not consume the expensive storage space of the server. Figure 1. P2P Transfer in One Picture Cons & Pros of P2P Transfer P2P technology is popular in many industries such as film and media, Internet TV, telemedicine, it not only provides freedom and facility to data transfer but also integrates all potential Internet resources. In technical expert’s opinion, P2P transfer is a kind of instant technology for quick data moving and sharing, it is beneficial to creating opportunities for enterprises in today’s market environment driven by data. However, with 5G emerging and the continuous development of information technology, P2P transfer is undoubtedly a double-blade sword, so it’s difficult for enterprises to step forward. Pros: Low cost: save the cost on the server. Efficiency improved: remove the intermediate procedures and establish simple connections. High stability: eliminate the server-centered single-point service in the past, form the decentralized P2P transfer organization, which solved the fault problem caused by the central single point. Cons: Network bandwidth resources are consumed in large quantities: The concurrent connection of P2P transfer makes the resources consumed in large quantities, it is easy to cause network congestion and reduce the performance of other applications. Inconvenient management: The P2P transfer is decentralized, the amount of users is huge thus it’s hard to take care of all users. Security risks of data leakage: The widely use of P2P transfer leads to someone use the loopholes in the system to invade user privacy and destroy data. Some criminals even add viruses in the P2P transfer process, which poses a threat to users' computer security. The P2P transfer technology is not strong enough to satisfy enterprises’ various needs, therefore, there must be a breakthrough. According to whether the clients are in the same network environment, the difficulty degree of P2P transfer technology is different. What modern technologies can be used to optimize and how to optimize? Let's continue to explore the principle of P2P technology and try to find a breakthrough. P2P technology upgrading Based on NAT+Raysync The transmission protocol of Raysync has abandoned the use of transmission messages as both byte counts and TCP protocol. With its revolutionary UDP transmission method, Raysync overcomes faults in existing TCP-based file transfer protocols . The transmission speed of FTP/HTTP is hundreds of times higher and is not reduced by the size of the file, transmit distance, or network difficulties. Raysync can offer secure internal and external sharing of data, enabling you to securely upload, download and edit files on a user-friendly interface. Send huge files via mobile devices and web browsers in every location and anywhere. Characteristics Raysync transmission protocol may make full use of a broad network of bandwidths for the fastest transfer of data. It can enable users in the huge data distribution application scenario to finish the big data transfer in the least time. The multi-channel parallel transmission feature of the link is supported by RaySync Transmission Protocol. When a client interfaces between point B and point A, a multiplicity of unrelated data streams can quickly be transferred in Parallel via the multi-parallel channel property. The transfer of these data streams does not require the handshake connection process, which considerably enhances the transmission in real-time. Raysync transmission protocol is UDP-based and may transit over various NAT devices smoothly. Here we divided into two situations for analysis: On the same network Assume that the internal network interface is 1000M, the LAN bandwidth is 10M, and the bandwidth utilization rate is 50%. Client A and Client B are in the same network environment, as shown in the following figure. If the traditional file transfer method is adopted, the A user needs to upload the file to the server first, and then B can download it from the server, there only 10M network bandwidth will be utilized in the whole transfer process. While through peer-to-point transfer, A and B can directly establish a connection, file transfer makes full use of the network bandwidth of 1000M, and the transfer efficiency can be improved by 100X. Figure 2. P2P technology on the same network Raysync combined the P2P technology with Raysync ultra-high-speed transfer protocol, the network bandwidth is fully utilized up to 96%. The file transfer process is accelerated, the TB-level big data and massive data transfer have never been easier. Figure 3. P2P technology upgrading Based on NAT+Raysync On the different network Client A and client B are in two different network environments, and they need to try to connect with the target end to judge whether they can penetrate the network to establish communication. The P2P transfer between two clients will be different according to different clients. Several common P2P transfer methods through middleware include Relaying, Connection reversal, UDP hole punching. Through the following characteristic comparison table, we can simply grasp the characteristics and application scenarios of these methods. Table 1. Characteristics and compassion table According to the methods listed above, Raysync P2P transfer will try to connect with the recipient end in priority. If it is failed to connect, it will be connected by reverse connection or UDP punching. If it is still failed to connect, then the server transfers will be adopted. Raysync will automatically select the best transfer mode in the whole process, reduce the network burden and make full use of network resources. Besides, the P2P transfer based on UDP needs to consider the type of NAT, because the penetration ways of different NAT combinations are not consistent, some can penetrate, while some cannot. Figure 4. P2P technology on the different networks Digging deep into NAT penetration technology, Raysync combines more than 10 NAT penetration technologies with Raysyncb ultra-high-speed transfer protocol and simultaneously applies on P2P transfer. In practical application, the penetration effect of these 10 NAT combinations can meet the current P2P transfer needs. Even in the face of a few impenetrable situations, Raysync may still be able to improve the transfer efficiency and find the optimal solution for P2P transfer. A More Universal P2P Transfer through Innovation on Speed and Management Transfer acceleration ensures efficiency improving In the peer-to-peer transfer, the patented Raysync ultra-high-speed transfer protocol is adopted. This protocol can eliminate the bottleneck at the bottom layer, it is immune to limitation of the traditional network and hardware, fully utilize the network bandwidth, and realize ultra-low latency, high speed, and end-to-end output service, the transfer rate is improved by nearly one hundred times, thus easily achieves the safe, controllable and stable transfer of TB-level large files and massive small files. Figure 5. P2P technology on the different networks about penetration and acceleration Comparison of the peer-to-peer transfer efficiency Test environment: Shenzhen-Beijing, network latency 35ms~45ms, packet loss rate 1% Server: Alibaba cloud Shenzhen, CentOS 8.3, 2 vCPU 4 GiB, bandwidth 100M, SSD disk ClientA: Alibaba cloud Shenzhen, CentOS 8.3, 2 vCPU 4 GiB, bandwidth 100M, SSD disk ClientB: Alibaba cloud Beijing, CentOS 8.3, 2 vCPU 4 GiB, bandwidth 100M, SSD disk File transfer is automatic For team collaboration, Raysync supports automatically receive peer-to-peer files from your partners. Compared to the traditional P2P transfer method, Raysync saves your time spend on manually file reception. The auto file reception can be realized with one click to enable the “Allow to receive transfer files from partners” button. A data asset is strictly monitored The admin user can monitor every single task in the admin console. Enter Raysync admin console – peer-to-peer transfer, you could view the peer-to-peer transfer account, IP, task name, receiver ID, country, states, city, total file transmission quantity, and transmission speed. In the meantime, it supports viewing the details of the peer-to-peer transfer task being transmitted and stopping the operation, and supports one-click viewing and downloading for historical transfer tasks. All files and individuals traceable, each P2P task can be controlled by the admin. The comprehensive upgrade made by Raysync on P2P transfer overcomes the drawbacks of file and user management, enables peer-to-peer transfer to better meet the enterprise needs, and helps enterprises manage data more efficiently. Bank-level data security Based on the needs of customers in industries such as film and media, IT Internet, Raysync adopts AES-256+TLS encryption technology between client and server to guarantee end-to-end data security. Aiming at the port problem, Raysync only needs to expose one port, which can meet all users' access needs and greatly reduce the risk of firewall port exposure; Hash verification protection is carried out at the transfer message level, file block, and the whole file to ensure the integrity of the transfer content. The optimization made by Raysync on peer-to-peer transfer, which has outstanding performance in performance, reliability, and security. The upgraded management design meets the needs of modern enterprises. As a one-stop solution provider for large file transfer, Raysync can be used as a tool for enterprises to realize fast file cooperation, and can also be used as an enterprise data management platform to provide data transfer services for industries such as film and media, finance, IT Internet, etc.

MFT means managed file transfer. The term MFT began to appear in the mid-2000s. In the field of file transfer, it is a brand-new method of data transfer that enterprises have begun to use, and it is clearly distinguished from "file transfer protocol" in the 1980s. As defined by Gartner, “Managed file transfer software and services enable users to manage and monitor file transfers within and between organizations.” In this definition, Gartner uses “manage” and “monitor” to highlight and explain the key differences between MFT and FTP. - Manage – means to manage all file transfers using one interface across all business units, operations, systems，applications, partners, etc. - Monitor – means to monitor all file transfers in one centralized location which in turn means better governance, compliance，and reduced IT costs. Driven by increasingly stringent privacy regulations and the need to quickly transfer and track files globally, many organizations are in the process of replacing their legacy FTP systems and moving towards MFT solutions. In fact, managed file transfer solutions are gaining the most momentum. We explain to you what does MFT means? At present, we easily find that no matter in the fields of health care, government, technology，or media，the information now will inevitably move around. In some cases, such data may have to leave the organization's security controls to enter customers or other business systems. The traditional file sharing way can comply with personal needs, for example, sending private messages or videos. But this kind of way does not comply with the enterprise needs. MFT is dedicated to creating a more secure and efficient IT environment within the enterprise. Enterprises that use MFT solutions often deal with sensitive information on a regular basis, making security the core of their business functions. Managed File Transfer, as the acronym implies, is a service that manages data and ensures its security during transfer. Enterprise organizations often use it, and it can get rid of slow and temporary methods such as FTP and HTTP. In the final analysis, a good MFT solution should simplify your transfer process and comply with security standards such as SSL encryption solution provided by Raysync). A good MFT solution should include: 1. The secure connection. 2. Encrypt data being stored or "still". 3. A reverse proxy that acts as a pass-through and does not write any unencrypted data to the server. 4. The ability to support an organization's security policies, such as password expiration or SSL.
