How to Improve the Security of Big Data Transfer?
Facing the challenges and threats related to the security of big data transmission, the industry has conducted targeted practices and investigations on security protection technologies. This article focuses on three aspects of the development of big data security technology: platform security, data security, and privacy protection. Technologies related to platform security, data security, and privacy protection are improving, allowing us to solve big data security issues and challenges. However, to respond to new methods of cyber attacks, protect new data applications, and meet increased privacy protection requirements, higher standards and functions will be required. In terms of platform technology, centralized security configuration management and security mechanism deployment can meet the security requirements of the current platform. However, vulnerability scanning and attack monitoring technologies for big data platforms are relatively weak. In terms of technologies for defending platforms from network attacks, current big data platforms still use traditional network security measures to defend against attacks. This is not enough for the big data environment. In the big data environment, the extensible defense boundary is vulnerable to attack methods that cover up the intrusion. Besides, the industry pays little attention to potential attack methods that may come from the big data platform itself. Once new vulnerabilities appear, the scope of the attack will be huge. In terms of data security, data security monitoring and anti-sabotage technologies are relatively mature, but data sharing security, unstructured database security protection, and data violation traceability technologies need to be improved. Currently, there are technical solutions for data leakage: technology can automatically identify sensitive data to prevent leakage; the introduction of artificial intelligence and machine learning makes the prevention of violations move toward intelligence; the development of database protection technology also provides a powerful way to prevent data leakage Guarantee. The ciphertext calculation technology and the data leakage tracking technology have not yet been developed to the extent that they can meet the needs of practical applications, and it is still difficult to solve the confidentiality assurance problem of data processing and the problems related to tracking data flow. Specifically, the ciphertext calculation technology is still in the theoretical stage, and the calculation efficiency does not meet the requirements of practical applications. Digital watermarking technology cannot meet the needs of large-scale and fast-updated big data applications; data lineage tracking technology requires further application testing and has not yet reached the mature stage of industrial applications. Digital watermarking technology cannot meet the needs of large-scale and fast-updated big data applications; data lineage tracking technology requires further application testing and has not yet reached the mature stage of industrial applications. Digital watermarking technology cannot meet the needs of large-scale and fast-updated big data applications; data lineage tracking technology requires further application testing and has not yet reached the mature stage of industrial applications. In terms of privacy protection, technological development clearly cannot meet the urgent need for privacy protection. The protection of personal information requires the establishment of a guarantee system based on legal, technical, and economic methods. Currently, the widespread use of data desensitization technology poses challenges to multi-source data aggregation and may lead to failure. So far, there are few practical application case studies for emerging technologies such as anonymization algorithms, and there are other common problems with this technology, such as low computational efficiency and high overhead. In terms of computing, continuous improvement is needed to meet the requirements of protecting privacy in a big data environment. As mentioned earlier, the conflict between big data applications and personal information protection is not just a technical issue. Without technical barriers, privacy protection still requires legislation, strong law enforcement, and regulations to collect personal information for big data applications. Establish a personal information protection system that includes government supervision, corporate responsibility, social supervision, and self-discipline of netizens.
Powerful Storage Function Does Raysync Large File Transfer System Own
As a solution provider for large file transmission, Raysync has a self-developed ultra-high-speed transmission protocol, which can easily meet the extremely fast transmission requirements of TB-level large files and massive small files, and provide professional large file transmission and transmission management services for major enterprises. What designs have been made for file storage in Raysync? What storage methods does Raysync support at present? Today we give answers to these two questions. Let's first clarify the three concepts of object storage, file storage, and block storage: Object storage: A strategy of managing and manipulating data storage as different units . These objects are stored in a separate warehouse and are not affected by files in other folders. Get each piece of data and designate it as an object. The data is stored in a separate warehouse, instead of a file in a folder, and is bound with the associated metadata and unique identifier to form a storage pool. File storage: Data is stored as a piece of information in a folder to help organize data among other data. This is also called layered storage, which imitates the storage mode of paper documents. When you need to access data, your computer system needs to know the path to find data. Block storage: Split a file into individual data blocks, and then store these blocks as separate data. Each piece of data has a different address, so there is no need to store them in a file structure. Among the above three storages, object storage adds comprehensive metadata to files, eliminates the hierarchical file structure used in file storage, and places all contents in a flat address space called a storage pool. Object storage has no archive hierarchy, and the source data is completely customizable, so compared with file or block storage, the restrictions are much less and the resources are optimized; At the same time, data can be added forever, and unlimited scalability greatly reduces the storage cost of data; Faster data retrieval and better data analysis promote the wide application of object storage. The use case of the object storage: Providing rich media: Define workflow by using industry-leading solutions to manage unstructured data. Reduce the cost of rich media distributed globally. Managing distributed content: Optimizing the value of data throughout its life cycle and providing competitive storage services. Embrace the Internet of Things : Effectively manage machine-to-machine data, support artificial intelligence and analysis, and reduce the cost and time of the design process. Storage methods supported by Raysync: As an enterprise-level large file transmission software, Raysync has provided high-performance, safe, and stable large file transmission and transmission management services for 2W+ enterprises in IT, finance, film and television, biological genes, manufacturing, and many other fields. As shown in the above table, Raysync has a powerful file storage function, supports more than ten mainstream object storage services, and can meet the diverse storage needs of enterprises.

What causes the slow transfer of large files? How to solve this problem?
The increase of data is the inevitable development of science and technology, and the big data brought by the progress of the times is both an opportunity and a challenge. For the problem of slow transmission of big files, we should think: Is the big data itself or the improper way to deal with the data the root cause of enterprises falling into the dilemma of big data? 1. The challenges brought by big data to file transfer 1) Large Amount of Data How big is the amount of data? Now, the files basically start at GB level, and TB and PB files can be said to be the most frequently encountered file transmission units in the office of medium and large enterprises. 2) Low Transfer Efficiency The amount of data increases, the existing network bandwidth is limited, and the network is congested. If we encounter the situation of weak network, long-distance, trans-provincial and trans-national, the transmission speed of large files is simply terrible, and the trans-national transmission of 10GB files may take several tens of hours. 3) High Risk Network security threats have caused the cost of data leakage to soar. Exposure of sensitive data in the process of data transmission and enterprise interaction; The cloud storage associated with file transfer status and the operation of office workers all have potential risks of data leakage. 2. The Solutions 1) Improve the work efficiency via a large file transfer tool Professional file transfer tool software has perfect countermeasures on packet loss, latency, and transmission efficiency of large file transfer, which can greatly improve work efficiency. For example, Raysync, which is equipped with Raysync high-speed transmission protocol and intelligent compression technology, can meet the high-speed transmission requirements of ultra-remote, cross-border large files, and massive small files, and at the same time make full use of the existing bandwidth of the network to effectively reduce the impact of network latency and packet loss. 2) Select one of the most ideal transfer modes Point-to-point, multi-point mutual transmission, data cloud transmission, one-to-many data distribution, and other modes are often needed in enterprise offices, but there are few large file transmission tools that can really meet the above requirements. Raysync supports providing multiple modes of transmission according to different transmission initiators, and enterprises can intelligently choose according to actual needs. 3) Strengthen storage function and pay attention to software compatibility To solve the problem of file storage in the process of large file transmission, Raysync supports the mainstream cloud platform operating systems such as Alibaba Cloud, Amazon Cloud, Huawei Cloud, etc., and provides special SDK integration products, which can be quickly integrated and deployed with the existing systems of enterprises, and easily build an automated file transmission network for network environments and heterogeneous systems within or between enterprises. 4) Bank-standard security protection and global central control In order to ensure the security of data transmission and prevent data leakage, cracking, monitoring, and other security issues, Raysync strengthens the security control of internal data communication, adopts AES-256 encryption technology of online banking, and uses SSL encryption transmission in the transmission process to effectively ensure data security. At the same time, Raysync adopts the setting of access rights and OS rights, thus achieving stricter access control. 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 File Encryption Software?
File encryption software is a free or paid tool that can encode your information so that it remains safe when it is on the move when it is at rest or both. Protecting sensitive data is essential for any organization, and file encryption software is heavy work. File encryption software uses one of several complex algorithms to scramble the contents of your files, making them unusable and unreadable until they are decrypted using the appropriate key provided by the sender. There are three main parts that determine the security of the encryption method: the appropriate degree of the encryption system used for the data to be sent, the strength and complexity of the scrambling algorithm, and the key length. The length of the public-private key is 128 and 256 bits, while the public key is 2048 bits. Why do organizations need to encrypt files? The data is encrypted to prevent unauthorized parties from accessing information they shouldn’t. Obviously, financial conglomerates and healthcare organizations that deal with sensitive banking or private healthcare information separately should protect the data transmitted through their systems, while companies in various industries encrypt mobile and static data. Encryption is only part of the puzzle, but companies can get multiple benefits by using file encryption software: Better data protection. File encryption software should not be the only security measure on your network security roster, but it can add other layers of your existing data protection to other layers, such as secure networks, connections, employee training, and business practices. Send safely. An effective file encryption software solution helps to ensure that the files on any device are protected during the entire operation, whether they are stationary or in motion. Interceptions. Although data theft is the most famous type of destruction, interception and tampering are another threat that file encryption can defend against. Bonus: The best file encryption software will confirm that your data has not changed. Follow compliance guidelines. Many regulations include file encryption expectations, and file encryption software can help you meet that expectation. Why should I use file encryption software? File encryption, compliance, and network security: triple threats. For good reasons, compliance with regulations and requirements is increasingly dependent on encryption. Better encryption software and data security measures can avoid some of the biggest data leaks and fines this year. Well-known regulations including PCI DSS, GDPR, and HIPAA all emphasize that encryption is a key technical strategy to ensure data security. Almost everything related to compliance can be linked to network security. Compliance requirements usually outline the minimum conditions considered the safe-a blueprint for compliance that an organization can follow to achieve a strong cybersecurity stance. Prevent data leakage: develop the right data encryption strategy By encrypting information in mobile and stationary states, you are taking a critical step towards improving network security. The recent encryption failures and fines-in some cases even new guidelines have been proposed-are led by small businesses and large multinational conglomerates. Security Researcher Violation When security researchers discovered insecure Amazon S3 buckets containing personal data of nearly 3 million users, the Berlin-based app TVSmiles was compromised. This violation made Germany lean towards new personal data protection guidelines and showed that even relatively small databases can contain massive amounts of data-all of which are mature if they are not protected. Bad results in healthcare Hospitals, clinics, and public health organizations collect and store large amounts of very sensitive personal data, which makes them the main targets of hacker attempts. Two recent events include: A U.S. health insurance company was hit by the second-largest HIPAA violation penalty for violating safety regulations. After investigation, the Office of Civil Rights determined that the company had “failed to implement sufficient hardware, software, and procedural mechanisms to record and analyze information system-related activities.” Human error led to data breaches, and Public Health Wales posted more than 18,000 online Personal information of a Covid-positive Welsh resident and kept it for 18 hours. Unrest due to data breach EasyJet confirmed in the spring of 2020 that the personal data of 9 million customers had been leaked. They also revealed that customer data is not the main target-just an unlocked space leading to Crown Jewelry. Although the reason for the EasyJet data breach has not been disclosed, it is clear that their network security is lacking in key areas. Takeaway How can file encryption software help? By ensuring that the data you are transmitting or storing is safe and only accessible by parties with the appropriate decryption key. In some of the above cases, file encryption software will be an additional layer of security to prevent data leakage and meet the software requirements outlined in requirements such as HIPAA and GDPR. The best file encryption software The best file encryption software for your organization depends on your unique requirements. However, during the search, please keep the following in mind: What requirements or regulations does your organization comply with? Do these stipulate certain standards that you must meet? If your data is public, what are the risks? How sensitive is it? Some personal data protection requires a distinction between low-risk data and high-risk data. If your data is leaked, it may adversely affect the fine. Does your trading partner rely on a specific encryption standard or format? If you choose the same method, will it speed up or simplify file transfers? Are you exchanging large files or large amounts of data? Some file encryption software will have automation features that can speed up your process , and some software options can handle large files better than others. A flexible, jack-of-all-trades software solution is Managed File Transfer , which can encrypt and automate all file transfers. Most MFT solutions will encrypt files on the move and encrypt them with the encryption standard of your choice, including leading technologies such as Open PGP, AES, SSL, and SSH.

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.
The History of Large File Transfer
The first file is exchanged via removable media. In the mid-1980s, asynchronous modems took over where the dual synchronization stopped. Then, in the 1990s, the Internet changed the game of using persistent connections to transfer files between enterprises via HTTP, FTP, and SMTP. In the following years, a large number of B2B managed file transfer solutions emerged, which helped organizations meet the increasing security, compliance, and operational requirements of mobile information. Despite all these changes, business-to-business file transfers are still basically the same as in the 1970s. The transportation channels and agreement portfolio have changed, but the process and methods are the same. In 2015, B2B data exchange belonged exclusively to technical users who performed file-based batches, and the pricing of professional file transfer software solutions reflected this. For example, when two companies want to automate data exchange, the IT departments of both companies need to discuss data format, transmission protocol, encryption, transmission confirmation, and error/exception handling. Considering that the automatic file transfer function is not the highest priority of most corporate IT departments, it can be a long and frustrating process for business users who delay or lose waiting for IT revenue. This process can take several weeks to automate the data exchange with a company, and it must be repeated for hundreds or even thousands of customers/suppliers again and again. Because of this, the B2B file transfer and integration market has become very mature. What is a "secure, managed" file transfer? It is important to exclude some term definitions. File transfer is a general term that applies to the act of transferring data through a computer network, private or public, and therefore the Internet. Hosted file transfer is designed to facilitate file transfer, it is a software or service used to provide secure internal, external, and temporary data transfer over the network. Secure file transfer is another term, which is usually an integral part of file transfer software; the secure part usually refers to a specific function. Historically, programmers wrote scripts to automate batch FTP functions. This works fine within a limited range, and if the configuration is rarely changed. However, when an organization exchanges data with many customers and partners, and when passwords, libraries, and IP addresses are constantly changing, relying on scripts can quickly become troublesome. Using hosted file transfer products can help your business avoid data leakage. You will get restrictions on allowed senders and recipients, centralized recording of data transmission, secure encryption of data, and functions that integrate with data loss prevention products.
How to Make File Transfer More Secure?
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.
