Java 21 Training Course

Participants will gain a clear understanding of the specific applications of selected topics, the common challenges associated with their usage, and the role played by the application model. The training also covers fundamental knowledge of standard library functions. Attendees are expected to have prior experience with Java development environments (such as Eclipse or NetBeans). Please note that user interface design is not included in this course.

Even seasoned Java developers do not automatically master all the security services provided by Java, nor are they fully aware of the various vulnerabilities that impact Java-based web applications.

This course introduces the security components of Java Standard Edition (Java SE) and addresses security challenges within Java Enterprise Edition (Java EE) and web services. Before exploring specific services, the course covers the fundamentals of cryptography and secure communication. Through practical exercises, participants learn about declarative and programmatic security techniques in Java EE, as well as transport-layer and end-to-end security for web services. All concepts are reinforced through hands-on exercises where participants can experiment with the discussed APIs and tools.

The course also examines and explains the most common and severe programming flaws in the Java language and platform, along with web-related vulnerabilities. Beyond typical errors made by Java developers, the discussed security vulnerabilities encompass both language-specific issues and problems arising from the runtime environment. Each vulnerability and corresponding attack is demonstrated through easy-to-follow exercises, followed by recommended coding guidelines and mitigation strategies.

Participants attending this course will

• Understand fundamental concepts of security, IT security, and secure coding
• Learn about web vulnerabilities beyond the OWASP Top Ten and know how to prevent them
