Disadvantages of decentralized database

1. blockchain is not broken. Blockchain itself is a kind of decentralized database, which can be accessed but not tampered with. Therefore, it is a very secure data chain

2. Chongqing jinwowo network: decentralization, which is different from the traditional way of centralization. There is no center, or everyone is the center; Distributed ledger database means that the recording method is not only to store the ledger data in each node, but also to share and the data of the whole ledger synchronously. At the same time, blockchain also has the characteristics of disintermediation and information transparency.

3. Xu's view is very clear. Decentralization does not mean deregulation, which mainly refers to the intermediate process. The essence of blockchain is to omit the intermediate procrastination process and allow users to trade one-to-one. But that doesn't mean it can't be regulated. On the contrary, as an advanced database management technology, blockchain is characterized by easy data storage, which is more convenient for the third party to supervise and control, but the third party does not affect the transaction.

4. Database is the soul of all software now. To put it bluntly, to do software is to read and write database. Software without database is almost worthless

5. Shanyan massive object storage MOS is designed to provide massive unstructured data storage solutions. It adopts decentralized and distributed technology architecture, supports 10 billion level files and EB level capacity storage, and has the ability of efficient data retrieval, intelligent labeling and analysis. It can easily cope with the storage challenges in the era of big data and cloud, and provides intelligent decision-making for enterprise development.

Do you have a secret

are you worried about the security of computer data

have you ever thought that computer theft and loss will also cause data leakage

have you ever thought that computer maintenance personnel can steal confidential information when they repair your computer

have you ever thought that the internal staff of an enterprise can easily divulge secrets by means of mobile storage devices (such as USB flash disk), mail, file transfer, upload, etc

private information or technical data are stored in the computer in electronic form and transmitted through the network or removable media, so the security is difficult to be guaranteed. Once the information is leaked, it may cause incalculable losses to indivials or enterprises. Therefore, data encryption is the most effective way to solve the problem of information leakage

The

k / 3 data security platform is a series of information security software procts based on the concept of automatic protection, which can automatically, dynamically and transparently encrypt the data stored on the computer, with high encryption intensity and high security level, and can effectively improve the security and confidentiality of the intranet

With the development of information technology, in order to improve the efficiency of information processing, more and more enterprises turn documents into electronic documents, and even store more than 90% of their confidential information in the enterprise intranet in the form of electronic documents. At the same time, enterprises also use ERP, CRM, OA and other database related electronic information management solutions. The use of these new management means brings higher proction efficiency to enterprises, but also brings new challenges to the information security management of enterprises. Although the enterprise has adopted anti-virus software, firewall, intrusion detection, identity authentication and other means, it is still unable to prevent the electronic information from leaking out from the enterprise in various ways. Most of the current network security technology starting point is to solve the problem of external protection, internal protection is very weak. In the face of increasingly serious information security threats, the original security solutions of enterprises are graally inadequate

1 almost every enterprise will encounter the problem of "reasonable" tax avoidance; Once the leak, the enterprise will enter a very passive state

2 almost every high-tech enterprise should protect its technological secrets; Once divulged, enterprises will lose their core competitiveness and instry leadership

3 almost every enterprise has to protect the commercial privacy of bidding documents, contracts and quotations. Once the secrets are leaked, the enterprise will lose customers

Information security threats

2.1 according to pollemont Research Institute, the average loss of enterprises in data intrusion is increasing year by year. The average loss of data intrusion to enterprises is 6.6 million US dollars, and the loss of some companies is even as high as 32 million US dollars. The biggest loss of data intrusion is the loss of business. According to it, of last year's average loss of $202 per record, $139 (69%) refers to lost business

2.2 according to the results of the special network security survey concted by FBI and CSI on 484 companies, more than 70% of the security threats come from within the company. In terms of the amount of losses, the losses caused by internal staff leakage are 16 times of those caused by hackers and 12 times of those caused by viruses

2.3 according to the investigation of China National Information Security Evaluation Center, the real threats to information security are mainly caused by internal information leakage and internal crimes, rather than viruses and foreign hackers

3. Common ways of leakage

3.1 hackers leak information by ing information through installing malicious software (such as Trojan horse program)

3.2 when the computer is infected with virus, it will automatically send out the secret

3.3 data leakage caused by computer theft and loss

3.4 internal personnel information through mobile storage devices, or leak information in the form of e-mail, file upload, etc

3.5 the third party maintenance personnel steal information by taking advantage of their work, resulting in leakage

4. Encrypt confidential information, and thoroughly solve security risks

4.1 all confidential information should not flow out of the enterprise at will

4.2 all confidential information should be circulated transparently within the enterprise to eliminate security risks without affecting normal business operation

4.3 all confidential information can be set with various security levels and used according to authorization

4.4 there is only one controllable and unique security exit for confidential information

5.3 infinitely scalable secret level management mechanism

flexible "department" + "secret level" management mechanism, fully controlling the flow of confidential information, truly realizing any fine-grained control

the security platform compares the "department" and "secret level" authorization of the personnel with the "department" and "secret level" attributes of the file. Only when the Department is consistent and the "secret level" authorization of the personnel is greater than or equal to the "secret level" attribute of the file, can the encrypted file be opened normally

when the administrative structure of an enterprise changes, the "department" and "secret level" can be added or inserted at will, and the relevant authorization can be inherited automatically without special processing of encrypted files, which can easily cope with future expansion

when the file needs to be used by other departments within the enterprise temporarily, the "department" and "secret level" attributes in the file can be changed to new "department" and "secret level" through OA approval process or in the client of the security platform

when some personnel in the enterprise need to work across departments, they can be granted corresponding "department" and "secret level" operation permissions to specific personnel through the security platform console
