Is SQL injection illegal?

Hackers can access the information as well as the system of different users through many ways and steal their information or damage their system, and this choice depends on the hackers, and they tend to choose one of the types of hacking methods according to their purpose in order to penetrate the systems, on the other hand, users are trying to increase the security of their system as much as possible to block the way for hackers, one of the steps that they should take, is trying to study articles which are related to security and hacking issues in order to gain mastery and increase awareness in this regard, in this article, we are going to review insert a malicious code into the SQL statement through web page input.

Is SQL injection illegal?
In general, any way in which different people can access the users’ information without their permission is illegal, and those who do so will be punished, in this type of attack, if the hackers can carry out the attack completely, they can access a lot of personal information, for instance, bank card information, important personal information, etc., all of which can make a lot of money for hackers, on the other hand, they will compromise user security, the interesting thing about this type of attack is that the users may not be aware of the fact that they have been hacked for a long time, and as a result, during this time, the hacker can continue to steal their important data, as well as accessing more important information day by day, this kind of hacking attack and has different types, among which, the following can be mentioned.

Examples of SQL injection:
- Retrieving hidden data:
Through this way, it is possible for the hacker to access a lot of information which the site owner did not want to share it with applicants, for example, imagine that you enter a site in order to buy a product, and different lists are displayed on the website, in this section, hackers enter a command asking the website to provide more information about the products which are not included in it.

- Subverting application logic:
Imagine that you see a program that allows users to log in by entering a password and username, in such a program, a hacker can enter the password and username which finally allows them to log in through the SQL comment sequence, in this type of attack, eventually, the hacker can modify the query to interfere with the purpose of the program, and replace their desired target instead of that, in order to reach their desired results.

-Retrieving data from other database tables:
In this type of attack, the hacker can finally use other tables exist in the database in order to retrieve the data by performing the desired actions and using the SQL injection vulnerability, to do this, hackers use the “UNION” keyword, and as we mentioned, through this type of request, they can access a lot of information, in fact, when hackers enter their request, they can access a lot of information.

- Examining the database:
In this method hackers need to have more information about the database and once they have access to the information in the database, they can access their desired information, in general, through this attack, it is possible for the hacker to obtain information about the columns of the database, in other words, they can retrieve data from various database tables.

- Blind SQL injection vulnerabilities:
Through this method of attack, hackers can gain information illegally .

In this method, in fact, no data is returned and that is why it is named like that, through this way, hackers can inject a new request into the site and access the information they want, the hackers can also examine the time that the information process takes through this method and according to this amount of time, they can check the correctness of the process.

In general, hackers use this method in order to gain a lot of information, so it is necessary for you as a user to protect your system against such attacks, in the following section we are going to mention some solutions available to increase system security .

What should we do against SQL injection attacks?
As you have noticed so far, in this method, malicious codes are sent to the system and databases through forms, and through this way, they access the information they want, as a result, one of the ways to increase security in order to protect your information against this type of attack is to increase the security of the forms, so that hackers cannot easily achieve their goal through this way.

- It is necessary to increase the speed and efficiency of the site during SQL attacks , so that it can defend the information in such cases in the best way possible, for gaining high level of security, you can use the query method and examine all the data carefully to close the way for hackers to infiltrate.

- Do not forget to update all the content in your system constantly, because in each version that is provided by one program, there are some bugs that the owners of the program will try to fix them in the next version, for example, newer versions may fix the problems that SQL Injection causes, as a result, with the help of updating process, you can provide more security and protect your data in the best way.

- In order for users to be able to make better use of the site, you may have to warn them and send them mesغیر مجاز می باشدes repeatedly, through which hackers can access vulnerabilities on the site, as a result, they use these vulnerabilities to gain access to information.

- while choosing your passwords, try to be careful and use the strongest ones, because if you do not use the right passwords, hackers can access your information as well as system easily, therefore it is necessary to use safe and strong passwords which contain at least 8 characters, including uppercase, lowercase letters, numbers and various elements, so that the hacker cannot guess the password easily, and they can finally access the whole system.

- Observe all the available security tips in the best way, so that you can bring the security to the highest level , at the same time, you should pay attention to the security of the hosts and observe the available tips, so that hackers cannot achieve their goals.

- Minimize user access as much as you can, and check that whether users have accessed to your databases or not regularly, and if you find out that users have accessed your information, you should try to take the necessary steps quickly and block the way for hackers in order not to let them enter your system and gain access to your information.

- Change the database prefix, so that hackers cannot achieve their goals by using hypothetical prefixes, which is one of the ways that can have a great effect on increasing the security of the site against such attacks.

- Use high security templates for your site, and through this method you can increase the security of your system and information.

- Get help from powerful and up-to-date antivirus so that they can alert you to viruses, so you can take the necessary security measures.

- Get help from white hat hackers, so that they can check the security level of your site and give you the necessary information about it.

Last word:
In general, any attempt by hackers and profiteers in order to gain access to the information and systems of different users is illegal, and various punishments exist for such people, in this article we tried to examine the illegality of SQL injection attacks , and we tried to mention the steps that you can take in order to increase the security of the site and database against such attacks, so that hackers cannot access your system as well as your important information.
