SQL Injection
SQL injection is a security vulnerability that occurs when an attacker inserts or manipulates malicious SQL code into input fields or queries, allowing unauthorized access to or manipulation of a database. It exploits improper input validation and can lead to data theft, corruption, or deletion. This is a critical issue in web applications that interact with SQL databases.
Developers should learn about SQL injection to prevent security breaches in applications that use SQL databases, such as e-commerce sites or user management systems. Understanding it is essential for implementing secure coding practices, like parameterized queries and input sanitization, to protect sensitive data from attackers. It's a fundamental skill for roles involving database security or web development.
