Today, I will talk to you about several common ways to invade the database, which may not be well understood by many people. in order to make you understand better, the editor has summarized the following contents for you. I hope you can gain something according to this article.

With the rapid development of the Internet, more and more enterprises take the Internet as a high-speed train to make their enterprises develop better and stronger. With the increase of business volume, the database pressure of an enterprise also follows.

There are many tasks in the enterprise's security protection of data assets, including data backup security, data storage security, data desensitization and encryption. Most of the people with usability-based business security views do not fully understand the importance of database security, and according to forward-looking statistics, more and more enterprise information security leaders began to include database security segments in their memo list.

There are many ways to invade a site. A website from development to online operation, need to go through a lot of links and a lot of personnel. Any weakness of any link or personnel may be exploited, resulting in huge losses.

Next, this article will give you a list of the ten common security issues in the database.

1. Error induced statement of SQL. A wrong induced SQL execution statement may cause the application server to execute the command, thus compromising the security of the database. 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 a system, and the security level is the top priority. Encryption keys are usually stored on the company's disk drive, and when the key is lost, your company's system will be hacked.

3. The enterprise's database was stolen. The database of an enterprise is usually threatened by two aspects, one is an aboveboard attack from the outside, and the other is that there is a "mole" inside the enterprise, and steal the database of one's own enterprise. for example, if Ctrip's website was paralyzed on a large scale a few years ago, it may have been done by a mole. 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 permissions between administrators and ordinary users are managed separately, so that the "mole" will face more challenges if they want to steal data from the database. If you can limit access to user accounts, it will be more difficult for hackers to control the entire database.

5. Incorrect operation behavior in the database. We know that vulnerabilities can often lead to data being hacked or deleted, so as developers, we have to check the database for dangerous situations all the time. Therefore, programmers need to use tracking information / logs to query and solve problems.

6. The data was accidentally leaked. 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 not solve all problems. In practical work, many companies value that search engines play a great role in promoting the improvement of business. We know that index can improve search efficiency, but search engine optimization (SEO) can have an effect on it only when the database is sorted. But testing these functional lines can improve performance, but testing cannot predict all the problems that will occur in the database. Therefore, after the database supporting facilities are complete, it is necessary to conduct a comprehensive inspection of the database to find out the advantages and disadvantages.

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

9. There are weaknesses in the system. In the process of attacking the database system, hackers generally do not immediately control the entire database system. They usually choose the weak repudiation in the system framework to break through, attack, and then 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 case, we can see how important it is to strengthen the maintenance of the database. Therefore, it is important to strengthen the maintenance of your company's data at all times.

Although database security incidents continue to occur, a certain number of security officials still believe that enterprise security protection has carried out multiple defenses from the physical layer, network layer, computing host layer, application layer, and so on, and the network boundary is strictly controlled. External threat intelligence and internal situation awareness systems can perfectly cooperate, business data has long been protected layer by layer, security threats can not be used to produce database security incidents. Contrary to the facts, it is precisely because of this illusion that events are more likely to occur, and as a result, accidents may occur frequently.

Database is the core part of the enterprise, and all the important information of the enterprise is in the database. Therefore, it is everyone's unshirkable responsibility to do a good job in the security protection of the database. Only when hidden dangers are found and eliminated can hackers be shut out.

After reading the above, do you have any further understanding of several common ways to invade the database? If you want to know more knowledge or related content, please follow the industry information channel, thank you for your support.
