Description
Secure Code in Java and Spring Bootis 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 byAndrii Piatakha, a best-selling instructor on Udemy with over1,000,000 students worldwide. Andrii is known for his unique and proven methodology that perfectly blendsclear theoretical explanationswithdeep practical exercises. His teaching style helps students internalize complex security concepts through action, not just memorization.

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