What's an SSL certificate? SSL certificates are what enable websites to move from HTTP to HTTPS, which is more secure. An SSL certificate is a data file hosted in a website's origin server. SSL certificates make SSL/TLS encryption possible, and they contain the website's public key and the website's identity, along with related information. Devices attempting to communicate with the origin server will reference this file to obtain the public key and verify the server's identity. The private key is kept secret and secure. Why do you need SSL certificates? A website needs an SSL certificate in order to keep user data secure, verify ownership of the website, prevent attackers from creating a fake version of the site, and gain user trust. 1. Transfer encrypted data on the internet to prevent theft. 2. Maintain the integrity of data in the transmission from endpoint A to endpoint B. 3. The encrypted data is transmitted to the server through the public key in the SSL certificate, and the server decrypts it with the private key to prove its identity. Raysync SSL certificate configuration: Login to the Raysync admin portal -> Setting ->TLS certificate, upload the corresponding certificate, and you can also choose whether enable Prohibit non-SSL connections option or not on this page. 1. The transfer server only supports encrypted certificates issued by formal root certificate service providers, which prevents self-signed low-strength encrypted certificates from becoming system vulnerabilities. 2. When the transport client finds that the transport server certificate has expired, it will refuse to communicate with the transport server and prompt the server that the certificate has expired. 3. The transmission server will regularly check the valid time of the encryption certificate , and when the valid time is less than or equal to 30 days, a prompt will pop up on the admin portal, prompting the administrator to replace the encryption certificate in time. Note: If the prompt of the certificate is expired shown in the admin portal, you need to upload the certificate again to ensure the transfer security.

Imagine taking work home and using a laptop to complete a large report or spreadsheet, and then realize that you need to use the file on your actual work PC. Fortunately, you just need to transfer the files to the new computer and you don’t have to redo the whole thing on the second computer. Whether it is one file or multiple files, there are many ways to transfer files between PCs. The time is taken by each method largely depends on the amount of data to be transferred. No matter which method is used, more data means a longer waiting time. External hard drive An external drive provides one of the easiest ways to transfer files between two PCs. Insert the drive into the first computer, drag and drop the files to be transferred onto the external drive, then insert the drive into the new computer, drag the files from the drive, and copy them to the new computer. External drives include small USB flash drives and large external hard drives. If you want to transfer a large number of files, consider using a large-capacity drive to reduce the travel distance between the two computers. Windows easy transfer All Windows 8 and Windows 7 computers have Windows Easy Transfer Program. If your old computer does not have the latest operating system, you can also download this application for Windows Vista and XP. The program provides a variety of data transfer methods, including transfer via USB drive, Internet, and special Microsoft Easy Transfer cable. Using the Internet and Easy Transfer cable options, you don't have to worry about the data to be transferred exceeds the storage capacity. In addition to simple file transfer programs, Windows Easy Transfer also enables you to transfer programs and Windows settings. Cloud storage With cloud storage, you can store data on a hard drive somewhere on the Internet instead of a local device . The speed of cloud storage services depends on two main factors. First, your Internet connection plays a role: a faster connection leads to faster file uploads and downloads. Another factor is the service itself, because some services may perform better and faster than others. For example, a full-featured paid service may be faster than a free solution, and if you are paying for additional storage space, you can transfer more services at once. Please refer to the Resources section for a collection of free and paid cloud storage services. Email For small files, email may be the fastest solution to transfer several files from one computer to another. Most email clients allow you to add attachments to emails. Attachment size limits vary from client to client. Most Word or Excel documents are small enough to be easily transferred via email. Open a new email and attach the file, then send the email to yourself. Log in to the email on the second computer and your files will be waiting in the new message you just sent.

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.

The large file transfer software used by enterprises will involve all aspects of enterprise data and information. Besides the security control of large file transfer software itself, the security design of enterprise user behavior is also very important. Aiming at the safety of enterprise users, Raysnc has designed strict transmission settings and user behavior control, control so as to realize visible, controllable, and traceable enterprise data flow. 1. Enterprise users The Raysync server completely records the behavior logs of users logging in, logging out, uploading, downloading, changing passwords, sharing links, etc., and the administrator can regularly audit the user behavior information. 2. Software administrator The Raysync server completely records the administrator's operation log, including adding, deleting, modifying user information, modifying server information, and other complete information and auditors can regularly audit the server administrator's operation behavior. 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.

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. 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 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.

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.
