Description
SQL injections are one of the most common and dangerous vulnerabilities found in web applications, even though they have been well documented for decades. This paper explores the effectiveness of common prevention techniques against SQL injection attacks, including input validation, parameterized queries, and prepared statements. To demonstrate, a vulnerable web environment was created using Damn Vulnerable Web Application (DVWA) to simulate attacks and observe how each defense method withstands different injection attempts. The results will show the strengths and weaknesses of each approach when tested against real-world attack patterns. In addition to testing, this research highlights the relevance of SQL injections in today’s cybersecurity environment, shown by their inclusion in the OWASP Top 10 [4]. By demonstrating how easily unsecured applications can become victims of attacks and how effective proper countermeasures can be, this paper highlights the importance of implementing secure coding practices in modern web development.
