What does "SQL Injection" mean?
Table of Contents
SQL injection is a type of attack that targets databases through web applications. It happens when an attacker sends harmful commands to a database using input fields, like forms or search boxes. If the web application does not handle this input safely, the attacker can gain access to or manipulate the data stored in the database.
How It Works
In a typical scenario, a user might enter information into a website's form. If the application fails to check this information properly, an attacker can insert malicious code instead. This code can allow the attacker to retrieve sensitive data, modify records, or even delete important information.
Risks
SQL injection poses serious threats to data privacy and security. It can lead to loss of sensitive data, unauthorized access, and damage to the reputation of the affected organization. Businesses may face legal consequences and financial losses if their users’ data is compromised.
Prevention
To protect against SQL injection, developers should use safe coding practices. This includes validating and sanitizing user input, using prepared statements, and employing web application firewalls. These steps help ensure that any harmful commands do not reach the database.
