Secure Coding Testing - OWASP Top 10

Introduction

Secure coding testing involves evaluating the security aspects of software applications to identify vulnerabilities and weaknesses. This lesson focuses on the importance of secure coding practices and testing as outlined in the OWASP Top 10, which is a list of the most critical web application security risks.

Key Concepts

Testing Process

The testing process for secure coding typically follows these steps:

1. Identify security requirements based on OWASP Top 10.
2. Conduct static analysis to detect potential vulnerabilities.
3. Perform dynamic analysis through penetration testing.
4. Review findings and prioritize vulnerabilities.
5. Implement fixes and validate through regression testing.

Best Practices

Implementing secure coding practices can greatly reduce vulnerabilities:

• Validate and sanitize user inputs.
• Use prepared statements for database queries.
• Implement proper error handling and logging.
• Regularly update dependencies and libraries.
• Conduct regular security audits and code reviews.

Code Example: Preventing SQL Injection

                // Using prepared statements to prevent SQL injection
                const mysql = require('mysql');
                const connection = mysql.createConnection({...});

                const userId = req.body.userId;
                const query = 'SELECT * FROM users WHERE id = ?';

                connection.query(query, [userId], (error, results) => {
                    if (error) throw error;
                    // handle results
                });
