Secure Code in Java and Spring Boot: Build Resilient Apps

Secure Code in Java and Spring Boot is the ultimate guide for developers who want to write production-ready, secure applications using industry-standard tools and best practices. Security is no longer optional - it's a critical part of every developer's skill set. This course gives you the deep, practical knowledge you need to write code that defends itself.

You’ll learn how to protect your Java and Spring Boot applications from the most dangerous vulnerabilities: SQL injection, XSS, CSRF, insecure deserialization, misconfigured authentication, broken access control, and more. You'll go far beyond theory—each topic is backed by hands-on examples and real-world scenarios.

What makes this course different?

This course is designed by Andrii Piatakha, a best-selling instructor on Udemy with over 1,000,000 students worldwide. Andrii is known for his unique and proven methodology that perfectly blends clear theoretical explanations with deep practical exercises. His teaching style helps students internalize complex security concepts through action, not just memorization.

You won’t just learn how to avoid insecure code - you’ll learn how to write secure, efficient, and maintainable Java and Spring Boot applications that are ready for production and compliant with modern security standards like OWASP Top 10.

You will learn how to:

• Implement strong authentication and role-based access control with Spring Security

• Protect APIs with JWT, OAuth2, and secure token handling

• Prevent SQL injection using JPA, Hibernate, and parameterized queries

• Avoid Cross-Site Scripting (XSS) and Cross-Site Request Forgery (CSRF)

• Use encryption and hashing (e.g. AES, bcrypt) the right way

• Secure microservices communication and configuration

• Validate and sanitize user input effectively

• Handle secure file uploads and prevent injection attacks

• Store credentials and secrets safely

• Apply Secure Development Lifecycle (SDLC) practices

• Use automated tools to detect vulnerabilities in your code and dependencies
