How can SQL injection be prevented?

There are some interesting topics these days that have attracted a lot of users, one of which is hacking. Hackers are always trying to use new methods to access other users' information. One of the dangerous ways hackers may steal users' information is  SQL injection, which is one of the most popular attacks among hackers. As we have mentioned before, hackers are always trying to find new methods to achieve their goals. As a result, they know many ways to infiltrate other systems without the permission of their owners, but there are several ways that they are very interested in. This injection is one of these ways.

As different hackers try to gain access to users' information, users are becoming more and more concerned about the security of their systems. For example, one of the concerns of users is how they can prevent various hacking attacks. In this article, we will take a look at one of the concerns among users and mention the ways to prevent  SQL injection attacks.

What is this injection?

This attack is one of the most well-known software and  security vulnerabilities, SQL, which stands for Structured Query Language, is the most commonly used language for interacting with databases, as you know, important information is stored in databases, which may include bank card information, username, passwords, etc., all of which are of great importance, this data is secured when it is transferred to a database or vice versa by using arguments, but the important point is that hackers can gain access to important information from places where your application communicates with an SQL reasoning database, in fact, through this attack, hackers can retrieve data that is not visible to the user and use this information to achieve their goals.

This type of attack is one of the most common ones among hackers, and they use this attack to cause a lot of harm to the users' system. Through this method, they can also access other people's information. They modify or delete it, there have been many reports to date about damage to various systems through this method, and sometimes hackers use it to  hack web servers. In this method, hackers insert malicious code into the SQL statement through the web page entry.

How can this injection be prevented?

To avoid the danger of  SQL injection, you need to learn how to prevent these attacks from happening and do your best to withstand these types of attacks. In general,  increasing security in computer systems  can be an easy task if your awareness level is very high. You act carefully, for example, about these types of attacks that can cause serious damage to different users' systems. It can be said that, if you know secure encryption methods and if you can do them, you can prevent these attacks from happening, to  protect your information against such attacks, you need to perform the following steps.

- In the first step, like all attacks you want to stand against, you should try to find weaknesses from which hackers can carry out their attack. You must discover vulnerabilities. Several tools can help you discover existing vulnerabilities, including Dynamic Analysis Tools (DAST) and  Static Analysis Tools  (SAST) dynamic analysis tools act like a white hat hacker and examine everything from a hacker's point of view so that they can finally find the weaknesses in it, and as we mentioned before, the static analysis tools can also help a lot to find vulnerabilities, this is the main step you need to take to prevent these attacks from infiltrating your system, and if you do this step carefully and discover all the vulnerabilities, you can go through the next steps, to find vulnerabilities, you should look for areas where your  application  is connected to a database.

- In the next step, you must repair all vulnerable points and then remove all of them. One of the most important things you can do to prevent this type of attack and other attacks is to do all the safety tips that help you  increase the security of your system  so that the level of security of your system increases and different hackers cannot steal your information easily.

Other tips to prevent SQL injection attacks:

Increase the security  of all forms that exist in the system. As you know, hackers implement their goals by entering malicious code in the forms transmitted to the system and the database, so it is necessary to secure all of them.

- one of the key points to  increase security  in these types of attacks and prevent them from happening is that all content and applications in the system should be updated regularly, this point should be taken into consideration because it can generally increase system security. It is effective against all attacks carried out by hackers. For example, it is possible that by updating,  SQL Injection  problems have been fixed in newer versions so that the hackers cannot penetrate the system through this attack and steal the users information.

- You should be careful while choosing your password because you have to use the strongest available passwords, because if you do not use the right passwords, hackers can easily gain access to your information as well as your system; therefore, it is necessary to use strong passwords that have at least eight characters, and the characters include uppercase, lowercase letters, numbers, and various elements so that the hacker cannot easily guess the password and finally access the system.

- Another point that should be taken into consideration to prevent this type of attack is restricting users' access as much as possible so that they cannot steal your information due to the limited permissions you give them.

- Site speed is very important when  SQL attacks  occur, and if the site speed is low, it is not possible to defend well against this attack.

- We have already mentioned that to find vulnerabilities, you can get help from tools that act like white hat hackers and report all vulnerabilities to you now. We must tell you that you can get help from  white hat hackers  and red hat hackers because they can help you find all the vulnerabilities and eliminate them as soon as possible.

Using different types of antivirus software programs can also help you  increase the security of your system. There are different versions of antivirus, and it is necessary to examine their different features to choose the best and most appropriate one according to your goal.

Try to minimize the messages you give to different users about the problems that occur on your site. These messages can show the weaknesses in your system to the hackers, so they will use them to infiltrate your system and access your essential information.

Last word:

In general, one of the attacks that are very common among hackers, and they use it to infiltrate various systems is  SQL Injection, which is necessary for all users to know how to prevent this type of attack from making them aware of this type of attack as well as the ways which they can use to prevent them from happening, so in this article, we have tried to tell you the important steps you need to take to prevent this attack, so if you pay attention to the points which we have mentioned above, they can help you a lot in the field of  increasing the security  of your system against SQL Injection attacks, because this type of attack is so popular among hackers, so it is necessary to know it better and take the necessary steps to not let hackers infiltrate your system through this type of attack.
