The SQL injection attack refers to an attack against a website or web application in which structured query language (SQL) code is added to an input field of a web form with the aim of accessing an account or modifying the data accounts.
When we talk about SQL injection attacks we are referring to a method that takes advantage of errors that exist in web applications. They are basically vulnerabilities that allow a possible intruder to inject malicious code to carry out their attacks and compromise the security and privacy of users.
The most common is the request for a username and password on a web page. Since many websites only monitor the entry of usernames and passwords, a hacker can use the data entry boxes to submit their own requests, that is, inject SQL into the database. In this way, hackers can create, read, update, modify or delete the data stored in the database, usually to access confidential information, such as social security numbers, credit card details or other information.
Keep in mind that in most cases SQL injection happens on websites. Therefore, it does not affect user devices. This makes security measures necessary on the part of those responsible for those pages. It is important that those responsible for web sites or applications have their services properly updated. It is vital to correct the possible vulnerabilities and therefore the importance of staying informed of vulnerabilities that appear and thus it is possible to prevent hackers from accessing the content.
And although this provides us with a strong barrier to security, there are still tools that can help us protect and improve the security of web pages and, in which case they are ours, provide better protection to users who enter it, thereby It will give a better name to the web page since users will feel safe and confident when entering it.
