Secure Web Application Development Using Python

The rapid growth of web technologies has increased the demand for secure web applications. As online services expand, protecting user data and preventing cyber-attacks has become a major concern for developers. Python has become one of the most popular programming languages for web development because of its simplicity, scalability, and strong framework support. This research focuses on secure web application development using Python, especially with the Django framework. Django includes built-in security features that protect against SQL injection, cross-site scripting (XSS), cross-site request forgery (CSRF), and authentication vulnerabilities. The study explores secure design principles, system architecture, and development techniques that contribute to building secure web systems. Additionally, it looks at security tools and practices like Object Relational Mapping (ORM), authentication modules, encrypted communication, and secure deployment strategies. The results show that Python-based frameworks allow developers to create scalable, secure, and efficient web applications while making development easier. The proposed architecture combines secure coding practices with modern web technologies to improve data protection and system reliability.
