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.

Employees are a valuable asset of an enterprise and the cornerstone of its development. With the development of science and technology, there are more and more Internet offices, and employees can work through computers and mobile phones, which significantly improves office efficiency. At the same time, the disadvantages of Internet collaborative work are also highlighted in the process of the rapid development of enterprises. The flow of personnel is a common occurrence, but due to the popularity of Internet collaborative office, employees can obtain internal information anytime and anywhere, which poses an increasing threat to the internal information and core data of enterprises. In some resignation cases, we can see that some employees delete their own historical documents after resignation, which leads to business failure and delays work progress. In case of departing employees who steal the internal core secrets of the enterprise, take away the key technologies of the enterprise or resell information for competitors to obtain higher benefits, the enterprise will be hit hard and seriously affect the development of the enterprise. In order to protect the information security of enterprises, we have made a lot of efforts. Today, we analyze two aspects: people and information, hoping to help enterprises pay attention to the hidden dangers of information security brought by personnel mobility and protect the security of assets. Responsibility supervision Background investigation: Job seekers need background investigation, which can be carried out after both parties agree. The main purpose of the investigation is to screen out employees with bad reputation records or threats to enterprises and do preliminary prevention work. Signing Agreement: Enterprises can sign Confidentiality Agreement or Non-Competition Agreement when hiring employees, specify confidentiality content, responsible subject, confidentiality period, confidentiality obligation and liability for breach of contract, and strengthen employees' sense of responsibility. On-the-job training: Carry out "confidential knowledge training" for new employees entering the company, and create clear and comprehensive strategies to accurately outline which information, data, and documents are the property of the company, emphasize the importance of information security, clarify the consequences of data leakage, and strengthen employees' sense of confidentiality. Safe exit: Employees who leave the company are required to hand over all access rights to information and equipment to the company. In case of termination of work in HR's on-the-job employee platform, the IT department should quickly intervene and quickly cut off the equipment that may be used for authentication or allow the departing employee to connect. Similar security measures should be taken for the third-party organizations, partners, or suppliers that the company cooperates with, and quick measures are the basis for the company to avoid heavy losses. Data protection We can take responsibility for supervision for people and enterprises, and at the same time, we can also carry out protection measures for enterprises' own data and information. Permission setting: E-mail, data documents, and other forms of Internet leakage account for a large proportion of data leakage incidents. In this respect, enterprises can divide the data types, grades, and employee permissions, and manage the access, download, edit, copy, delete, and other fine settings in terms of permissions. Here, we can refer to the scientific design of identity authentication, user grouping, file outgoing monitoring, etc. File backup: In the era of big data, small groups, enterprises, companies, and large groups all produce a large amount of data in the process of development. Backup is the most direct protection for enterprises to deal with data loss and external attacks. In other words, there are traces of backup files. Security of office environment: the emergence of mobile office software is both convenient and risky for employees. For employees who carry office equipment or need to use office equipment outside the company to work, enterprises should strengthen the encryption protection of sensitive data and monitor the data flow.

Enterprises rely on safe and reliable information access methods to meet today's rapidly developing market demand. Accordingly, sharing data internally and externally is essential for any organization. FTP is one of the earliest and still used data sharing methods. Although IT teams and business users are familiar with this, FTP lacks much vital security, compliance, and workflow requirements in modern organizations, especially in data security. The following are four different FTP vulnerabilities that are vulnerable to hackers: 1. Anonymous authentication Anonymous authentication is an FTP vulnerability, which allows users to use FTP username or log in anonymously. In many cases, users will provide their email address as a password. However, the user's login credentials and the commands used are unencrypted, visible, and easy to access. At the same time, any data sent via FTP or hosted on an anonymous FTP server will not be protected. Once, the FBI found that hackers actively used FTP to target medical and dental industries and access protected health information. 2. Directory traversal attack A directory traversal attack exploits insufficient security validation or sanitization of user-supplied file names, such that characters representing "traverse to parent directory" are passed through to the operating system's file system API. 3. Cross-site scripting Cross-site scripting is a type of security vulnerability that can be found in some web applications. XSS attacks enable attackers to inject client-side scripts into web pages viewed by other users. A cross-site scripting vulnerability may be used by attackers to bypass access controls such as the same-origin policy. Attackers can use XXS to send malicious scripts to unsuspecting users. The end user's browser cannot know that the script is not trusted and execute the script. Because the malicious script thinks that the script comes from a trusted source, it can access any data, session token, or other sensitive information stored on the user's local terminal that is reserved by the browser and used with the site. 4. Malware attack based on Dridex It was discovered for the first time in 2014 that Dridex malware has been re-invented and introduced in unexpected ways after the UK became the target of bank attacks. Internet users targeted by Dridex malware will open Word or Excel email attachments, which will cause macros to download the malware and infect computers, thus exposing users to bank theft. In the latest version of Dridex malware, hackers use FTP sites and credentials to avoid being detected by e-mail gateway and network policy of trusted FTP. Updating FTP credentials regularly can help prevent Dridex-based attacks. As far as the FTP server itself is concerned, it can no longer meet the system functions required by the big data business in the information age. From the point of view of security, transfer efficiency, and compliance, the FTP server itself cannot be expanded and it is very likely to bring high-cost loss. In the big data market, managed file transfer software came into being and was promised to meet the above business requirements. Large file transfer technology provides higher control and security than FTP, which usually has the following features: - In-depth report - The global visibility of all data transfer activities - End-to-end security, encrypting data in transit and at rest - Performance indicators, monitoring, and support for compliance requirements - Workflow automation Raysync - large file transfer software - 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 assisting enterprises to store, backup, migrate and synchronize their files in an orderly manner. 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.

More and more enterprises gradually realize that the amount of data generated by enterprises is increasing year by year, especially for enterprises with overseas business, which have customers in Japan, India, the United States, Southeast Asia, and other places. It is very difficult to transmit these data to the mainland for computing services. The amount of data is too large, and the amount of data contained in a project ranges from several hundred GB to several hundred TB. In terms of network transmission, the bandwidth utilization rate of transnational large file transmission is very low, because the current network transmission protocol is TCP transmission protocol, which is a stable and reliable transmission protocol. It is necessary to ensure that the data is transmitted without packet loss and the file is intact. Therefore, when the latency and packet loss appear together, it will choose to reduce the speed to ensure the quality. The farther the transmission distance is, the greater the probability of latency and packet loss. Therefore, in order to reduce the packet loss and ensure transmission quality and stability, the speed will be reduced. Raysync solves the problem of file transmission. Under the condition of high latency and packet loss, Raysync can improve the packet rate through self-developed protocols, control the congestion on the network, improve the transmission efficiency, and ensure the reliability and stability of the transmitted data. The bandwidth of Shenzhen is 100 megabytes, and files are transmitted from Shenzhen to Los Angeles, USA. Without Raysync, the bandwidth speed of 100 megabytes can only be less than 1 megabyte . If Raysync velocity is used at both ends, it can reach 92 megahertz. Raysync abandons the original TCP protocol during transmission, and takes over data packets and traffic packets through its own transmission protocol, thus improving transmission efficiency. As an expert in the field of large file transfer, Raysync will build an interactive bridge for the Internet, big data, artificial intelligence, and the real economy based on the self-develop high-speed transfer protocol.

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. Raysync is a professional service provider of enterprise-level file transmission, and it is also the first enterprise in China to provide commercial high-performance file transmission products. Raysync provides customers with high-performance, stable, and safe data transmission services in IT, film and television, biological gene, manufacturing, and many other industries.

In fact, today's business is increasingly driven by data. In order for your organization to be successful, it is important not only to send, but also receive, and access large amounts of data securely. However, the more you transfer, the greater the possibility of file security issues. So what would you do? As the saying goes, the best offense is a good defense. Although in many ways, the right communication solution can help. how should we better ensure the security of file transfer? Knowledge is the key. With the boom in the use of private chat applications, sharing data with a finger tap has become second nature. We quickly share GIFs, pictures, music, videos, documents, and sometimes sensitive data; usually not verifying the content or intended recipients, or worse, considering the consequences of sending the wrong content to the wrong individual. First, you need to be trained on the risks of transferring data. All your employees play an indispensable role in the security of the organization. Therefore, every employee must know why it is vital that every file is kept in the right hands. Transferring data on a private peer-to-peer network is a more secure option. Sending and receiving files peer-to-peer keeps sensitive data on your network. By avoiding middlemen, you can avoid potential error handling and malicious external threats. In addition, Raysync is faster than cloud sharing. Just drag and drop the file into the chat window, as long as you have a stable internet connection, and voila. No additional login. No upload and retrieval. No need to increase bandwidth. This means being able to enable and disable features for individuals, user groups, or all users. Importantly, it also means taking advantage of these functions. In this way, you can rest assured that your employees can use the platform efficiently and appropriately. You might think that a separate file transfer solution can provide you with better security. But it is still limited to one function. In fact, your file transfer is not the only aspect of internal communications you need to protect. Your text and group chats, voice, and video calls also need to be protected. If they happen on different platforms, the possibility of carelessness, error, and impropriety will only increase. Simplifying all communications on one platform is a better way to ensure that data stays in good condition, no matter how the data is transmitted. Protecting your data in today's hyper-connected world is no easy task. Although you cannot keep you alert for a second, your team must always pay attention and remain alert. But by paying attention to these tips, you can better protect file transfers while protecting your team communication.

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
