SQL injection attacks involve inserting malicious SQL code into queries to manipulate databases, allowing attackers to access or alter data unauthorizedly. These attacks exploit vulnerabilities in web applications that do not properly sanitize user inputs.
Challenges
- Data Compromise: Attackers can retrieve, modify, or delete sensitive data, leading to breaches.
- Unauthorized Access: SQL injection can grant attackers administrative access to databases.
- Application Disruption: Malicious queries can disrupt the normal functioning of applications.
Protection Strategies
- Input Validation: Implement strict input validation to ensure only expected data is processed.
- Parameterized Queries: Use parameterized queries or prepared statements to prevent injection.
- Regular Security Testing: Conduct regular code reviews and security testing to identify and remediate vulnerabilities.
