SQL Injection

👉 Overview

👀 What ?

SQL Injection is a code injection technique used to attack data-driven applications. Attackers use SQL Injection vulnerabilities to bypass application security measures.

🧐 Why ?

SQL Injection is widely used in data breaches to gain unauthorized access to sensitive data, such as customer information, personal details, and financial transactions. Being aware of SQL Injection can help individuals and organizations protect their data and maintain trust with their users.

⛏️ How ?

To prevent SQL Injection, use parameterized queries or prepared statements. Ensure that your application has least privilege access rights, and use web application firewalls.

⏳ When ?

SQL Injection has been a common threat since the early days of the internet. As long as databases continue to be a key component of web technology, the threat from SQL Injection will remain.

⚙️ Technical Explanations

In an SQL Injection attack, the attacker submits a database SQL command which is included in the user's query. The malicious data then produces database query results or actions that should never have been executed.
