Which attack involves inserting SQL commands into an input field?

The correct response identifies SQL Injection as the attack that involves inserting SQL commands into an input field. This type of attack takes advantage of vulnerabilities in an application's software. Specifically, SQL Injection occurs when an attacker is able to manipulate the input field to inject malicious SQL statements into a query, allowing them to interact with the database in unauthorized ways.

When the input is not properly sanitized, an attacker can modify database queries, potentially gaining access to sensitive information, executing administrative operations, or even deleting data. This attack highlights the importance of implementing robust input validation and using parameterized queries to prevent the execution of unintended commands.

Understanding SQL Injection is critical for anyone working in cybersecurity, as it emphasizes the need for secure coding practices to mitigate risks associated with database interactions.
