What Is Database Encryption

The necessity of database encryption large database management system platform is typically Windows NT and Unix, these operating system security level is usually C1, C2 level. They have user registration, user identification, Arbitrary access control (DAC), audit and other security functions. Although the DBMS on the basis of the OS added a number of security measures, such as access control based on permissions, but the OS and DBMS on the database file itself is still lack of effective protection measures, experienced online hackers will "bypass", directly using the OS tools to steal or tamper with the database files ...

Data encryption, database encryption technology Status quo and future trends? Can the product solutions in this area meet the needs of industry and enterprise users? Firewall is not a problem all of the anti-intrusion network security technology represented by the firewall is not equal to all information security. In the vast majority of information systems, the core data and data are stored in the way of the database, no encrypted database is like a locked file cabinet, for those with ulterior motives, plagiarism, tampering is a breeze. Therefore, the security of database should not be neglected. Database encryption system is to enhance the common relational database ...

End-to-end encryption policies must take into account everything from input to output and storage. Encryption technology is divided into five categories: file-level or folder-level encryption, volume or partition encryption, media-level encryption, field-level encryption and communication content encryption. They can be defined further by the encryption key storage mechanism. Let's take a look at the grim forecast: According to the US Privacy information exchange, One-third of the U.S. people will encounter the loss or leakage of personally identifiable information from companies that store data electronically this year. Whether that number is not exactly right, anyway the public knows the data leaks ...

There is no doubt that people who understand the technology of data encryption should be able to protect the security of the source of technology. 　　Because of the direct use of data, so that data even if the security crisis lost, was stolen, encryption protection can still guarantee the real content of the data security. But the flexibility of data encryption is the place where people have been criticized. From the initial information encryption is not convenient to transparent encryption, from the beginning of a single encryption to the current Multimode encryption, encryption technology is also constantly improving to cope with the increasingly rich demand for encryption. and the development of data encryption technology is not only this, in order to deal with the more ...

Research on privacy protection mechanism of cloud database based on decomposition and encryption lie 0, Chen Yue, Tan Peng, Yanggang, Li Wenjun According to the demand of the tenant for the data privacy protection under the Cloud database service mode, a cloud database privacy protection mechanism based on decomposition and encryption is proposed. The tenant defines the privacy constraint according to its privacy requirement, the Trusted Data Privacy protection module of the cloud service provider platform completes the least encryption attribute decomposition according to the privacy constraint, and realizes the data privacy protection by encrypting the data value of some attributes in the decomposition result, thus establishing the decomposition and encryption based on ...

, as cloud technology and large data gradually permeate business and personal life and work, it is easy for people to save and access data anytime, at the same time, the cloud technology is increasing the efficiency of the data security risk, how to ensure that the data security cloud is also a modern information technology development in the "normal" problem, 　　Especially enterprise application data security needs are imminent. However, the problem is grim, but smart software developers are "no fight unprepared", has already prepared the law of protection. such as invoicing industry's Nova-the wisdom of business invoicing, for the modern information by ...

Data encryption and decryption are very important in the security field. For programmers, storing user passwords in ciphertext in a database is important to intruders who plagiarize users ' privacy. There are a variety of front-end encryption algorithm can be used for data encryption, decryption, I recommend a simple database-level data encryption, decryption solution. Take the MySQL database as an example, it built the corresponding cryptographic functions (Aes_encrypt ()) and decryption functions (Aes_decrypt ()). Inserts encrypted data into the table insert in ...

The concept of blockchain to technology has been around for a long time, but with the heat of the past two years, it has gradually become known by the market and many technicians.

Cloudera recently released a news article on the Rhino project and data at-rest encryption in Apache Hadoop. The Rhino project is a project co-founded by Cloudera, Intel and Hadoop communities. This project aims to provide a comprehensive security framework for data protection. There are two aspects of data encryption in Hadoop: static data, persistent data on the hard disk, data transfer, transfer of data from one process or system to another process or system ...

Certification (authentication) means that the user must provide proof of who he is, an employee, an agent of an organization, a software process (such as a stock trading system or a software process for a Web ordering system). The standard method of authentication is to figure out who he is, what characteristics he has, and what he knows to identify his things. For example, the system stores his fingerprints, and when he accesses the network, he must provide his fingerprints on an electronic fingerprint connected to the network (which prevents him from using fake fingerprints or other electronic information spoofing systems) and allows him to access the system only if the fingerprint matches.
