This article will explain in detail the usefulness of the authorization function usually provided by the database management system. The editor thinks it is very practical, so I share it with you as a reference. I hope you can get something after reading this article.

Database management systems usually provide authorization functions to control the permissions of different users to access data, which is mainly to achieve the security of the database. Database security protection technologies include: database encryption (core data storage encryption), database firewall (anti-loophole, anti-attack), data desensitization (sensitive data anonymization) and so on.

Under the Web environment, the security of the database is particularly important. The guarantee of the security of the database is the shield of the security of the network website. In order to achieve the security of the database, the usual method is that the database management system provides authorization function to control the permissions of different users to access data.

Some methods to ensure the Security of Database

1. Security management of users

The first thing to ensure is the security of the permissions of database users, users must go through identity authentication when accessing the database, and for non-supervised users, limited permissions and special passwords must be set.

2. Define the view

Defining different views for different users can limit the scope of access for users. Through the view mechanism, the data that needs to be kept secret is hidden from the users who do not have the right to access the data, which can provide a certain degree of security protection to the database.

3. Data encryption

The hidden danger of data security is everywhere, so the encryption of data is an effective measure to protect database security.

Data encryption is the most widely used, cheapest and relatively reliable method. Data encryption is an effective means to protect data from theft or modification in the process of storage and transmission.

4. Start transaction management and fault recovery

Transaction management and fault recovery are mainly to deal with natural factors that occur in the system, and to ensure the consistency and integrity of data and transactions.

The main measures of fault recovery are log recording and data replication; the results of every step of the transaction operation are recorded in the system log file, and the important data are replicated. In the event of a failure, the transaction recovery is accurately completed by using the data copy according to the log file.

5. Database backup and recovery

The database system must take necessary measures to ensure that the database can be restored in the event of a failure.

Data backup needs to be carefully planned, a strategy is developed and tested before implementation, and the backup plan needs to be constantly adjusted.

6. Audit tracking mechanism

The audit tracking mechanism means that the system sets up the corresponding log records, especially the records of data updates, deletions and modifications, so that it can be verified in the future and ensure the security of the system.

7. Strengthen server security

In the three-tier architecture of Web database, the data is stored in the database server, most of the transaction processing and business logic processing are carried out in the application server, and the operation request to the database is put forward by the application server.

Therefore, strengthening the security of the database is the effective protection around.
