In the era of big data, the production and dissemination of information are growing exponentially, and the transmission of enterprise files is facing the current situation of insecurity.
Error in file data: a large amount of data is not transmitted in time, resulting in data error, and manual error checking is too cumbersome.
Hard disk loss: large files are transmitted in the form of sending and receiving hard disks. Once the hard disk is lost, the consequences are unimaginable.
Information leakage: Too frequent FTP transmission leads to firewall attacks and information leakage.
Loss of files: massive files cannot be transmitted completely at one time, which is prone to file loss.
Information security event inventory:
Memcache DDoS Attack: on March 1, 2018, GitHub suffered a DDoS attack with a size of 1.35TB. in the following days, NETSCOUT Arbor reconfirmed a reflection amplification DDoS attack with a height of 1.7 Tbps caused by Memcache DDoS.
Data leakage incident: A company announced that the database of a hotel was invaded, and at most about 500 million guests' information was leaked. In the same period, a special user posted that the resume information of over 200 million users in China was leaked.
How to ensure the security of big data transmission. Let's take a look at how Raysync experts interpret it.
- Data security protection:
TLS algorithm encryption, AES-256 financial grade encryption strength, protect user data privacy.
Raysync protocol only needs to open one UDP port to complete communication, which is safer than opening a large number of firewall network ports.
FTPS encryption technology adds SSL security function to the FTP protocol and data channel.
Encrypt certificate configuration, support configuration of confidential certificates, and make service access more secure.
- Security mechanisms:
Scan CVE vulnerability risk library regularly to solve risky code vulnerabilities.
In the development process, Valgrind/Purify is used to check the memory leakage.
Adopt high-performance SSL VPN encryption to provide user access security services in various scenarios.
- Account security protection:
Adopt a double factor strong authentication system, support USBKey, terminal hardware ID binding, and other password forms for authentication.
The user's password saved in the data is encrypted based on the AES-256 encryption algorithm, and even the developer can't recover the source password from the saved ciphertext.

With the explosive growth of data, the file transfer acceleration software was born. However, how to ensure the security of file transfer? How to ensure the security of transnational transfer?
In view of the above problems, we will analyze Raysync's six important security settings in this article, hoping to help more enterprises better identify the file transfer acceleration software.
The following is the diagram of Raysync system architecture:
From the system architecture diagram, it can be seen that the file transfer acceleration process of Raysync software is not complicated, mainly based on the self-developed Raysync high-speed transfer protocol, which realizes the file transfer acceleration.
Will safety design be so simple? In fact, security is a topic that enterprise data assets always pay attention to. In the security design, every step of the user's operation and every click may bury potential safety hazards. The Raysync has been designed safely from six aspects:
1. Web security design
2. Account & password protection security design
3. Transfer security design
4. Software installation & operation security design
5. Behavioral audit
6. Encryption certificate life cycle management

There are risks such as latency and packet loss when enterprises transfer large files. Using file transmission software can ensure high-speed and safe data transmission. With the mature process and simple operation of transmission software, enterprise data collection, integration and utilization can be easily realized.
1. Ensure the delivery of documents
Free and open-source FTP tools may be suitable for transferring small temporary files, but for large files, they are usually unreliable, which may cause latency or packet loss. The new disk I/O optimization technology of transmission software provides high-speed reading and writing guarantee for massive files and ensures the smooth delivery of files.
2. Enterprise-standard stability and reliability
The advanced mechanisms like smart impression, breakpoint resume, and error retransmission ensure the secure file transfer.
3. Audit logs and reports
Detailed audit logs and reports make all operations auditable, controllable, and traceable.
4. Bank-standard security
Based on SSL encryption transmission protocol and financial AES-256 encryption transmission technology, data security is guaranteed.
5. Ease of use
Raysync is easy to operate, allowing users to transmit large files anywhere and at any time, and supporting deployment in existing systems of enterprises without changing the original operating habits.
6. High-speed transmission
Rayysnc transmission protocol can make full use of the bandwidth network and transmit data at the fastest speed. In the application scenario of mass data distribution, it can help users to complete large file transmission in the least time.
If your enterprise is worried about file transmission, you can consider using Raysync software to bring you a high-speed, safe, and stable file transmission experience.

Imagine: after a busy day in the office, you finally come home to calm down and fall asleep in a comfortable bedroom. Just enjoying a quiet time, a buzz came and you didn't want to move. But in the end, you reluctantly opened your eyes from the warm bed and picked up the noisy work phone-there is urgent work! Urgent files to be transmitted.
This situation is not only a terrible nightmare but also a reality for many people. The lack of suitable office tools has greatly affected the productivity and opportunity of enterprises, among which file transfer software is an important office tool, especially in the era of big data. From life information exchange to value mining behind commercial big data, more and more industries and activities need to involve large file transmission.
In this paper, we will discuss several key points of solving the problem of file transmission by combining Raysync with UDP, so that we can better understand modern file transmission products.
Based on the transmission performance of UDP, Raysync breaks through the defects of traditional FTP and HTTP transmission, the transmission rate is increased by 100X, and the bandwidth utilization rate is over 96%. Multi-dimensional transmission mode meets the requirements of extremely fast transmission of TB-level large files and massive small files. Intelligently accelerate the transmission in the whole process, avoid packet loss caused by network latency, greatly accelerate the efficiency of file outgoing, effectively compress the length of file outgoing, and provide a perfect data transmission carrier.
Long-distance transmission is easy
File transfer may not be so urgent, and stable and complete file transfer is the most important thing at the moment. In order to prevent you from worrying about whether your files will arrive safely at overseas partners, it is necessary to find a high-speed, safe, and reliable file transfer software. Yes, there are free UDP file transfer tools, but the GB transfer limit of most tools is very low. If you have any questions about using UDP protocol, Raysync is happy to provide you with the preventive measures we have taken. It is easy to transmit large files in a long-distance and weak network environment.
Stable and reliable file transmission
Over the years, data attacks such as data leakage and hacker attacks have emerged one after another. It is very common for traditional file transmission methods to lose data packets during transmission, but this situation means that your production, research, business, and other aspects may face corresponding delays, and you may face high compensation in severe cases. The importance of file transfer is often underestimated, so there is usually no proper budget. Don't be afraid, understand that you have many choices, including flexible pricing, which will prevent you from sacrificing data. With the help of our UDP technology, the Raysync will minimize the packet loss rate, make the files stably transmitted, greatly reduce the time cost of enterprises, and effectively guarantee the benefits of enterprises.
Multi-task efficient processing
Adhering to the free UDP file transmission method may limit the customization options. You are limited to one user profile, and usually only one transmission task can be performed at a time. Therefore, you must prioritize the equally important items for transmission. But most of the time, this sort itself is unreasonable. What we need is software that can respond quickly to support the rapid development of business. Raysync is based on multi-industry service experience, and it is well known that enterprises should know the number of configuration files supported by the software and the number of processing tasks when choosing file transmission software. In multi-task processing, Raysync has a number of multi-user accounts and supports user-defined permissions and transmission settings.

In order to solve the problem of fast synchronous backup of large files, based on the high-speed transfer protocol, Raysync developed the synchronous backup function of GB/TB large files, which can increase the speed by more than 30 times.
There are three modes of the file sync function of Raysync, as follow:
1. Select file sync in every second/minute/hour.
Enter the interval time in the input box, and select the time unit in the drop-down box. For example, if 60 seconds is set, the synchronization task will implement every 60 seconds.
2. Select to run the sync task in XX hours XX minutes every day.
Time can be customized in the input box, for example, 16:10 every day, it will automatically start to sync at 16:10 every day.
3. Synchronize once at a specific time.
Raysync supports file sync only once at a specific time. For example, if you set the sync time at 2021-12-13 11:00, the sync task will execute at this time only once.

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!

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.

When many people transfer files, they may have a question, why is the speed of uploading and downloading different from expected?
In fact, the speed of uploading and downloading network data is not equal, which is often restricted by network bandwidth and equipment performance.
Method 1: Change the network
Individual users generally use the ADSL broadband network when surfing the Internet. If the uplink bandwidth is restricted by the ADSL network, the best solution is to replace the network with faster uplink bandwidth. Nowadays, fiber-to-the-home is popular all over the country. Fiber is the most ideal transfer medium in broadband networks. The advantages of fiber-optic Intern et access are exclusive bandwidth, stable performance, low cost of upgrading, no electromagnetic interference, small loss, strong security and confidentiality, and long transfer distance.
Method 2: Adjust the device
The first situation is that some companies will restrict employees' access to the Internet for security management and information control, and some restricted ports will affect the speed of receiving documents. Another possibility is that the router or firewall of the company has made res trictions. In the face of the above two situations, it is recommended that you consult the company's network administrator whether you can adjust the restrictions.
Method 3: Clear the process
If neither of the above points is true and it is temporarily slowing down, you can check the bandwidth pressure of the server. Check the server to see the current network traffic, whether there are too many requests for uploading files, resulting in too many processes, too much pressure on the server, and slow response. This is to try to pause or clean up some processes first and carry out transfer tasks in the queue.
Method 4: Raysync Large File Transfer
If the above method can't solve your problem well, we can recommend a large file transfer software - Raysync. Especially for an enterprise or team, large file transfer, transnational file transfer, and file transfer speed have a great influence on the data value. With the development of society, the requirements for the transfer speed of large files are getting higher and higher. Raysync is easy to use and has high performance, which can easily solve the problem of TB-level large files and massive small files.
The following is the specific troubleshooting method given when there is a gap between the uploading and downloading speeds and the expected ones in the actual file transfer.
Client check:
1. Test the external network bandwidth, and recommend to use speedtest to detect the local upload and download bandwidth, and check whether the speed has reached the speed bandwidth limit;
2. Confirm whether the telecom operator of the client is consistent with the telecom operator of the server.
Server check:
1. Enter the background of the corresponding server to check whether the Raysync license is activated and whether the bandwidth in the license information is the expected bandwidth;
2. Check the current network volume in the server to confirm whether there are more users and other users have occupied the bandwidth of the server;
3. Check whether the disk read-write rate of the server has reached the peak, and confirm whether other users of the server are reading and writing files, which affects the file read-write storage of other users.
