This article mainly explains "what are the common security problems in the database". Interested friends might as well take a look. The method introduced in this paper is simple, fast and practical. Let's let the editor take you to learn what are the common security problems in the database.

1. Error induced statement of SQL

Incorrect inducement of sql execution statements may cause the application server to execute commands, thereby compromising database security. In view of this problem, the best way is to use a firewall to protect the database network from intrusion.

two。 Improper key management

The key is the key of the system, and the security level is the most important. Encryption keys are usually stored on the company's disk drive. When the key is lost, your company's system will be attacked by hackers.

3. The database of the enterprise was stolen.

The database of an enterprise is usually threatened by two aspects: one is the aboveboard attack from the outside, and the other is that there are "ghosts" inside the enterprise, which steal the database of the enterprise. For example: a few years ago, Ctrip website was paralyzed on a large scale, which may be done by undercover. The best way to prevent the database from being stolen is to encrypt the database and keep it strictly confidential.

4. Administrator and ordinary user permissions are separated

The separation of permissions between administrators and ordinary users makes it more challenging for "informants" to steal data from databases. If you can limit the number of user accounts, hackers will face greater challenges if they want to control the entire database.

5. Wrong operation behavior in database

We know that leaks often cause data to be hacked or deleted, so as developers, we must check the database for dangers at all times. Therefore, programmers need to use tracking information / logs to query and solve problems.

6. Accidental data disclosure

Because the database is connected to the network, many hackers attack the database through these network interfaces, so it is necessary to use SSL encryption method.

7. Search engine optimization can't solve all problems.

In practice, many companies attach great importance to search engines, which greatly promote the development of business. We know that indexing can improve search efficiency, but search engine optimization (SEO) can affect it only when the database is sorted. However, these functional line tests can improve performance, but the tests cannot predict all the problems that will occur in the database. Therefore, after the completion of the database facility, it is necessary to conduct a comprehensive review of the database to identify its pros and cons.

8. Uninstall unknown applications

Research shows that in the case of these hackers attacking data, there will be a feature, that is, the data is abused. For example, hackers can use other applications in the computer to control the computer and hack into the database. Therefore, uninstall unnecessary and unknown application tools from your computer.

9. There are weaknesses in the system.

In the process of attacking the database system, the hacker usually does not immediately control the entire database system. They usually choose weak reply in the system framework to break through, attack and gain control of the entire database system.

10. The database is not effectively maintained

Compared with many of us who read in textbooks when we were at school, in 2003, a computer virus quickly occupied 90% of the world's computers in two minutes, paralyzing 312 million of the world's computers. This macro virus called "SQL Slammer" attacks port 1434 through a vulnerability in the SQL Server database and infects SQL Server in memory, and then infects a large number of infected SQL Server, resulting in SQL Server not working properly. From this situation, we can see the importance of strengthening database maintenance. Therefore, it is very important to always strengthen the maintenance of the company's data.

At this point, I believe you have a deeper understanding of "what are the common security problems in the database?" you might as well do it in practice. Here is the website, more related content can enter the relevant channels to inquire, follow us, continue to learn!
