Java 21 Training Course

Participants will acquire a comprehensive understanding of specific issue resolutions, fundamental challenges associated with application models, and the underlying mechanisms of the language standard library. Instruction assumes familiarity with integrated development environments (IDEs) for Java, such as Eclipse or NetBeans. The curriculum is designed to address technical requirements for government software development and does not cover user interface design.

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.
