Data leakage happens frequently, and this number continues to rise, and data security problems have been plaguing various institutions and organizations. By interpreting all kinds of data leakage events, we observe that the internal staff's dereliction of duty and irregular operation behaviors are almost 50% responsible for data loss and leakage. As long as you press a few keys, you can easily download or delete the valuable data assets of an enterprise. The loss of reputation, money, and time caused by human errors is almost incalculable. Enterprises invest heavily in personnel, training, office space, and advertising, and it is also necessary to invest in secure file transfer. A secure file transfer software, such as Raysync, ensures the safe transfer of important file assets to designated locations and ensures data security throughout the whole process: 1. Web-based security design - User-side Web portal and management-side Web Portal support access IP address isolation and port isolation. - Support some nodes to disable user plane Web Portal or management plane Web Portal - Support Http and Https, the administrator can disable the Http but only enable the Https service. - Https TLS 1.1, TLS 1.2, TLS 1.3, only open the encryption algorithm suite recognized by the industry as safe. - The Web page of Raysync, the effective range of session is only valid for the current visit page, completely eliminating CSRF cross-site attack. - Before each version is released, Huawei Cloud Online Professional Web Vulnerability Scanning Service is used to scan vulnerabilities and fix the latest released vulnerabilities in time. 2. Account & Password Protection Security Design - In the transfer process, the user password is encrypted by an asymmetric high-strength encryption algorithm. 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 for 10,000 times in one direction by using the PBKDF2 algorithm and 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 must be greater than or equal to 8 characters. 3. Transfer Security Design - In the transfer process, Raysync is protected by Hash verification at the transfer message level, file block and the whole file to ensure the integrity of the transfer content. - TLS 1.3 is used for encryption between the Raysync client and the Raysync server to prevent man-in-the-middle attacks on the network. - Raysync only needs to expose one port to the outside, which can meet all users' access and greatly reduce the risk of firewall port exposure. 4. Behavioral Audit - The Raysync server completely records the complete 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. - The Raysync server completely records the administrator's operation log, including adding, deleting, modifying user information, modifying server information, and other complete information. Auditors can regularly audit the server administrator's operation behavior.

FTP is designed as a simple mechanism, which can exchange files between computers when the new network and information security are not yet mature. In the 1970s, if you wanted to protect your server from unnecessary access, you just had to lock the computer room door. User access to data is controlled by the basic user ID and password scheme. At this time, the Internet does not exist yet, and the PC revolution will take ten years. Nowadays, the security of business file transfer has become the focus of enterprise protection, especially in computing systems, and file transfer between enterprises and even in cross-border transfer has become crucial for the development of global economy. However, the original native FTP function of TCP/IP is not designed for the file transfer requirements of modern enterprises connecting the whole world. At the same time, due to the progress of network detection technology, the proliferation of hackers, malicious software, and millions of network users, the basic security mechanism of FTP has long been unable to prevent. Risks associated with file transfer using FTP: 1. The native FTP does not encrypt data; 2. When logging in, the user name and password are transmitted in clear text and are easy to identify; 3. FTP scripts and batch files save user ID and password publicly, which is vulnerable to hacker attacks; 4. FTP is used alone, it does not meet the compliance requirements; 5. When using FTP connection, the transmitted data may be "copied" to the remote computer, and may not even reach the intended destination. This possibility will expose your data to third parties and hackers; 6. Regular FTP itself does not maintain file transfer records. Isn't it time you replaced your FTP server? It's time to make a change. First, check how FTP is applied in the enterprise. Secondly, determine how your enterprise manages and protects everyone's file transfer. Finally, determine whether your enterprise can use a secure file transfer solution software Raysync can provide you with a reference for purchase), and then evaluate the software to see how it meets your business needs.

The amount of data is growing explosively. Not only that, but the capacity of a single file is also increasing. These documents, audio, video, drawings, and other materials may be the carriers of important business data for enterprises, especially for film and television production, life science research. For data-intensive industries such as production and manufacturing, the high-speed and secure transfer and management of data is of paramount importance. Usually, we use email, GoogleDrive, FTP to transfer, but when the file is large, reaching the GB level, the file transfer of the above scheme becomes extremely slow, unreliable, or even inoperable.

In the Internet age, big data movement is an inevitable problem faced by enterprises. You can choose traditional FTP, network disk, and other methods to transmit, which may be advantageous for small files. But for large file data, transmission speed trouble may appear. The slowness and unreliable data greatly affect the work efficiency of enterprises. The transnational transfer is even worse. The traditional network transmission method is extremely slow and has a large packet loss rate. After the transfer is interrupted, it needs to be retransmitted. It is extremely unstable in terms of data reliability and transmission speed. The time cost of using the hard disk delivery method is too large, which is unacceptable for efficiency-conscious companies. Therefore, the birth of transferring software effectively solves the problem of large file transfer for many enterprises! The main advantages of large file transfer software are as follows: 1. The transmission data is reliable, and the transmitted data is multi-layered at the transfer level to ensure the consistency of the transfer data; 2. Support interrupted resumable transmission, even if the transfer process is interrupted, it can resume seamlessly; 3. In terms of transfer speed, even cross-border long-distance transmission can maximize the use of bandwidth and maximize the transmission speed. According to actual test results, the transmission speed of big data can be increased by more than 100 times, and the maximum speed of a single connection can support 1Gbps; 4. The multi-channel design of the transfer protocol can save the transmission delay caused by the TCP three-way handshake to establish a connection when the user transmits data, and the real-time performance can be increased by up to 1 times; 5. The transfer performance is proportional to the bandwidth and has nothing to do with the transmission distance, and the packet loss rate has little impact; 6. Data security adopts encryption algorithm, and both the transmission process and data landing are encrypted; 7. Open multi-terminal SDK, easy and quick integration, etc. These are the advantages of large file transfers. I think each method has merits and the key lies in your transfer needs. Properly evaluate the needs of the transfer in order to choose the most efficient large file transfer solution.

FTP) is a common protocol in the file transfer process. Many companies build FTP servers to provide file download services. Here are two transfer modes for FTP. FTP differs from other services in that it uses two ports and one data port. And a command port . Usually, port 21 is the command port and port 20 is the data port. When the concept of active/passive mode is mixed in, the data port may not be 20. Active Mode The working principle of the active mode: FTP client uses N port to connect to port 21 of the FTP server, sends a user name and password to log in, and after successful login to list or read data, the client opens the N+1 port. Send the PORT command to the FTP server, tell the server-client to adopt the active mode and open the port; After receiving the PORT active mode command and port number, the FTP server connects through the server's 20 port and the client's open port to send data. Passive Mode The working principle of the passive mode: the FTP client uses N to connect to port 21 of the FTP server, and sends a user name and password to log in. After successful login, if you want to list or read data, send a PASV command to the FTP server. Open a port locally , and then tell the client the open port. The client then connects to the open port of the server through the N+1 port for data transmission. Active Mode VS Passive Mode The difference between the two is that when establishing a data movement connection, the main mode connection initiator is server-side, and the port 20 connects to the client's N+1 port to establish the data connection; the passive mode connection initiator is the client, and the client uses Port number +1 to connect to a high-order part of the server. Differences IN Network Settings Scenario: The FTP client and server are on different networks, and a firewall is required between the two networks. The client's FTP software sets the port segment opened in active mode, and the corresponding port segment can be opened on the client's firewall. There is a common problem: only port 21 is opened on the server-side, and no port is opened on the client machine. The passive mode adopted by the FTP client connection results in that the client can log in successfully, but cannot list and read data. It is because the server does not open the random port in passive mode. In passive mode, the open ports on the server-side are random, but the firewall must not be fully open. The solution is to open some random high-level ports in the passive mode of the FTP server configuration , and then set the rules in the firewall, open the corresponding port number on the server-side.
