SQL-Injection
SQL Injection is a type of cyber attack that targets databases used by websites and other applications. It happens when hackers use special commands to manipulate the data in the database. This can allow them to access sensitive information or even take control of the entire system.
Here’s how it works: when a user enters data into a form on a website, that data is sent to the database to be included in a query. A query is just a request for specific information from the database. Hackers can exploit vulnerabilities in the website’s code to insert additional commands into the query. When the query runs, those commands can do things that the website’s developers never intended.
For example, a hacker might use SQL Injection to add a new user account with administrative privileges, or to steal passwords or other sensitive information from the database. They can also modify or delete data, which can be very dangerous if the database is used for critical functions like banking or healthcare.
The best way to protect against SQL Injection is to make sure your website’s code is secure. This means using secure coding practices and regularly testing your website for vulnerabilities. You can also use security tools like firewalls and intrusion detection systems to help protect against attacks. By taking these steps, you can help ensure that your website and its users are safe from cyber attacks.
