Java Performance Training Course

Participants will gain insight into the specific applications of selected concepts, understand the fundamental challenges associated with their use, and explore the role of the application model. The training also covers essential knowledge of the Java Standard Library functions. It is assumed that participants are familiar with an IDE used for building Java applications (e.g., Eclipse, NetBeans). Note: This course does not cover user interface issues.

Even seasoned Java developers often do not fully master the diverse security services provided by Java, nor are they always aware of the various vulnerabilities relevant to Java-based web applications.

This course introduces the security components of Standard Java Edition while addressing security challenges in Java Enterprise Edition (JEE) and web services. The discussion begins with the fundamentals of cryptography and secure communication. Participants will explore declarative and programmatic security techniques in JEE through practical exercises, and examine both transport-layer and end-to-end security for web services. All components are demonstrated via hands-on exercises, allowing participants to experiment with the discussed APIs and tools firsthand.

The curriculum also covers the most common and critical programming flaws and web-related vulnerabilities in the Java language and platform. Beyond typical errors made by Java developers, the course addresses security vulnerabilities stemming from both language-specific issues and the runtime environment. These vulnerabilities and associated attacks are illustrated through accessible exercises, followed by recommended coding guidelines and mitigation strategies.
