Java Performance Training Course

Participants will gain insight into the specific use cases for selected concepts, the fundamental challenges associated with their implementation, and the role of application modeling. The course also covers essential knowledge of standard library functions within the Java language. Prerequisites include familiarity with the IDE used for developing Java applications (e.g., Eclipse, NetBeans). Please note that this training does not cover user interface development topics.

Even experienced Java developers do not always fully master the security services provided by Java, nor are they necessarily aware of the vulnerabilities relevant to web applications written in Java.

This course introduces the security components of Standard Java Edition, while also addressing security issues within Java Enterprise Edition (JEE) and web services. Before discussing specific services, we cover the foundations of cryptography and secure communication. Numerous exercises focus on declarative and programmatic security techniques in JEE, alongside discussions on both transport-layer and end-to-end security for web services. Through several practical exercises, participants get to experience these APIs and tools firsthand.

The course also examines and explains the most common and severe programming flaws in the Java language and platform, as well as web-related vulnerabilities. Beyond typical bugs made by Java developers, the security vulnerabilities covered include language-specific issues and problems arising from the runtime environment. All vulnerabilities and corresponding attacks are demonstrated through accessible exercises, followed by recommended coding guidelines and possible mitigation techniques.

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 how to avoid them
• Understand security concepts in web services
• Learn to utilize various security features of the Java development environment
