Introduction to Secure Coding

Welcome to the introduction to secure coding tutorial! In this guide, we will cover the basics of secure coding practices to help you write more secure software.

What is Secure Coding?

Secure coding is the practice of writing code that is resistant to attacks and vulnerabilities. It involves understanding common security threats and applying best practices to prevent them.

Common Security Threats

Here are some of the most common security threats to be aware of:

• Injection Attacks: These occur when malicious data is inserted into a query or command, leading to unauthorized access or data corruption.
• Cross-Site Scripting (XSS): This vulnerability allows attackers to inject malicious scripts into web pages viewed by other users.
• SQL Injection: This attack targets SQL databases by inserting malicious SQL code into a query.

Best Practices for Secure Coding

To write secure code, follow these best practices:

• Input Validation: Always validate user input to ensure it meets expected formats and values.
• Use Prepared Statements: Prevent SQL injection by using prepared statements with parameterized queries.
• Implement Proper Access Controls: Ensure that your application enforces strong access controls to protect sensitive data.
• Use Secure APIs: When using APIs, always use secure versions (e.g., HTTPS) and validate the data returned.
