Secure Coding Practices: Building Robust and Secure Applications

🔐 Input Validation: The First Line of Defense

Always validate user inputs to prevent injection attacks (e.g., SQLi, XSS). Use whitelists instead of blacklists for stricter control.

🛡️ Avoid Common Vulnerabilities

• SQL Injection: Use parameterized queries or ORM frameworks.
• Cross-Site Scripting (XSS): Sanitize output and use Content Security Policy (CSP).
• Buffer Overflows: Avoid unsafe functions like strcpy in C/C++.

⚙️ Secure Configuration Management

• Disable debug mode in production.
• Use environment variables for sensitive data (e.g., API keys).
• Limit permissions for services and users.

🔒 Data Encryption: Protecting Sensitive Information

Encrypt data at rest and in transit using strong algorithms (e.g., AES-256, TLS 1.3).

🧑‍💻 Authentication & Authorization

Implement multi-factor authentication (MFA) and role-based access control (RBAC).

🌐 Secure Communication

Use HTTPS for all external communications. Avoid insecure protocols like FTP or HTTP.
