Raysync | How to Transfer 100GB Large Files Cross-border?
Aiming at the problem of the transnational transmission of large files, we break down the problem into two small problems, so it is easy to draw a final conclusion. The factors that influence the transnational file transfer: Clarify the size of the enterprise's files Considering the problem of cross-border file size is mainly due to the high latency, high packet loss, and transmission interruption in cross-border transmission. FTP, the earliest open-source transmission tool in the market, supports transnational file transmission, but the speed of large file transmission can not keep up with the demand of large file transmission of enterprises; E-mail, network disk, and other transmission methods are also convenient. Transnational transmission is also faced with the same problems, such as limited speed and limited file size. Only small file transmission can be realized, and it cannot be considered in the case of massive small files. The fundamental needs of the required file transfer are clarified, and we can go to the next step to understand the influencing factors of the transnational file transfer. Small file transfer: mail and network disk can be easily solved. Large file transfer needs to consider factors of different aspect: transfer speed, stability, security, and ease of use. Raysync is equipped with the tool software of Raysync ultra-high-speed transmission protocol independently developed by Raysync, which perfectly explains the influencing factors and solutions of transnational file transmission, large file transmission, and massive small file transmission from the following seven aspects. - 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 to assist enterprises to store, backup, migrate and synchronize their files in an orderly manner.

Raysync Security Design: Software Installation
As with some other file transfer software, it takes a few steps to install Raysync including download the installation package, unzip, launch and activate it in three minutes, and then you can easily access the client. Then how to ensure the installation security so that to comprehensively protect the data security? Raysync focus on 5 details: - There is no built-in user name and password in the system, and the admin administrator password is randomly generated during the installation process, and it is forced to change the password when the administrator logs in for the first time. - The default restriction of the files that the user uploads are 660. Remove the execution attribute of the file and prevent the input file execution behavior. - Run the Raysync server with a low-privilege user. - Administrators can customize file suffixes that users can upload and prohibit users from uploading dangerous files. - The user rights of other groups of server program files are all closed to prevent other users from accessing abnormally.

How Does Raysync Manage the Transmission of Data?
Many companies have started the international business, and transnational file transfers have become more and more frequent. With the development of business and the expansion of the company scale, many companies have set up branches overseas. It has to be said that as the process of economic integration continues to accelerate, multinational operations of enterprises have become a trend. However, due to the constraints of transfer distance, file size, network environment, etc., the quality and speed of transnational file transfer are greatly reduced. Unexpected transfer interruption, packet loss, file damage, excessive time-consuming, file leakage, and other issues make it difficult for multinational groups to work. successfully launch.

Raysync Security Design: Account&Password Protection
Raysync is designed with multiple security protection based on the account number and password of the user. Specific security design is as follows: Account protection security design - Login authentication has a built-in anti-violence cracking mechanism, if the user enters the wrong password five times within 3 minutes, 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. Password protection security design - In the transfer process, the user password is encrypted by the asymmetric high-strength encryption algorithm, and even if the transfer message is intercepted, the attacker can not recover the plaintext through ciphertext. - The information stored in the database of the user password is irreversibly encrypted 10,000 times in one direction by using the PBKDF2 algorithm and the user's individual random salt. Even if the database information is leaked, the user password cannot be reversed through ciphertext. - The password must be a combination of case, number and special symbols, and the length is greater than or equal to 8 characters. - The system provides a weak password dictionary. Users can customize weak passwords that meet the password strength but are easy to be cracked by social engineering. System users are prohibited from using such passwords, such as @123. 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.
Raysync Security Design: Web Security
As a file acceleration transmission software, for the convenience of users, Raysync can be accessed directly on the web. The browser supports the convenient process of interactive operation, and we should strictly control the security of the browser. In the data transmission, we can simply divide the web into several layers: - Browser: Browser is the client, which provides data information interaction between the client and the server; - Http: When the client interacts with the webserver, there is a web request, which is based on the unified application layer protocol-HTTP protocol to exchange data. HTTP is a lightweight protocol, which requires no connection and provides fault tolerance for communication errors. - Middleware: Middleware is a general service between platform and application. - Server container: Server container is responsible for parsing user requests and scripting languages, such as Tomcat and JBoss. When we visit the web page, we see the content processed by the web container; - Database: Dynamic pages can provide interactive information query service, which mainly depends on the realization of web databases. Web pages containing forms are provided as access interfaces, and query results are also returned to users in the form of Web pages containing data lists. In view of the above points, the design of Raysync on web security: 1. User-side Web portal and management-side Web Portal support access IP address isolation and port isolation; 2. Support some nodes to disable user plane Web Portal or management plane web portal; 3. Support HTTP and HTTPS, and the administrator can disable HTTP and only expose Https service; 4. HTTPS TLS 1.1, TLS 1.2, TLS 1.3, only open the encryption algorithm suite recognized by the industry as safe; 5. On the Web page of Raysync login, the effective range of session is only valid for the current access page, completely eliminating CSRF cross-site attack; Before each version of Raysync is released, professional Web vulnerability scanning service will be used to scan vulnerabilities and repair the latest released vulnerabilities in time. 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.
What is AES Encryption and How Does it Work?
Advanced Encryption Standard is a block encryption standard. AES has the advantages of simple design, fast key installation, less memory space, good performance on all platforms, parallel processing support and resistance to all known attacks, and is widely used all over the world. AES is an iterative cipher with symmetric key packets, which can use 128, 192, and 256-bit keys, and encrypt and decrypt data with 128-bit packets. A perfect encryption algorithm is theoretically indecipherable unless an exhaustive method is used. At present, there are organizations in the world studying how to break the thick wall of AES. However, due to the long cracking time, AES encryption technology cannot be cracked at present. AES encryption algorithm has been widely used in financial, military, government, and other fields, so as to strictly guard against data security. The Raysync file acceleration transmission software fully responds to the call of national data transmission compliance and is based on SSL encryption transmission protocol and financial grade AES-256 encryption transmission technology to ensure data security. To provide users with a high-speed, safe, and convenient file transfer acceleration platform.
