Web Security: Common Vulnerabilities And Their Mitigation - Types of SQL injection

The video tutorial explains different types of SQL injection attacks: inband, blind, and out of band. Inband SQL injection uses the same communication channel for attack and data retrieval, with subtypes like error-based and union-based. Blind SQL injection involves no direct data transfer, relying on server response to infer database structure, and includes Boolean-based and time-based methods. Out of band SQL injection depends on specific database features to send data to an attacker, such as DNS requests.

What is the significance of Boolean-based SQL injection?

How does time-based SQL injection work and what does it rely on?

What are out-of-band SQL injection attacks and why are they less common?
