Which is an example of a SQL injection attack?
A SQLI is a type of attack by which cybercriminals exploit software vulnerabilities in web applications for the purpose of stealing, deleting, or modifying data, or gaining administrative control over the systems running the affected applications.
How are filters used to prevent SQL injection?
In some situations, an application that is vulnerable to SQL injection (SQLi) may implement various input filters that prevent you from exploiting the flaw without restrictions. For example, the application may remove or sanitize certain characters or may block common SQL keywords.
When to use the union keyword in SQL injection?
SQL injection UNION attacks. When an application is vulnerable to SQL injection and the results of the query are returned within the application’s responses, the UNION keyword can be used to retrieve data from other tables within the database. This results in an SQL injection UNION attack.
