Java Performance Training Course

During the training, participants will gain an understanding of specific use cases, common challenges encountered when utilizing them, and the role of the application model. The training also covers fundamental knowledge of standard library functions in the language. For government participants, this training requires prior familiarity with the development environment IDE used to build Java applications (e.g., Eclipse, Netbeans). The training does not address user interface issues.

Even experienced Java programmers may not fully master all the security services provided by Java, nor are they always aware of the vulnerabilities relevant to web applications written in this language.

This course introduces the security components of Standard Java Edition and delves into the security issues of Java Enterprise Edition (JEE) and web services. Before discussing specific services, the course covers the fundamentals of cryptography and secure communication. Various exercises focus on declarative and programmatic security techniques in JEE, as well as transport-layer and end-to-end security for web services. Practical exercises allow participants to use the discussed APIs and tools firsthand.

The course also examines the most frequent and severe programming flaws in the Java language and platform, along with web-related vulnerabilities. It covers both language-specific issues and problems arising from the runtime environment. Each vulnerability and associated attack is demonstrated through straightforward exercises, followed by recommended coding guidelines and mitigation techniques.
