Java 21 Training Course

This training enables participants to master the specific applications of selected Java features, address common implementation challenges, and understand the role of these elements within the application architecture. The curriculum also incorporates foundational knowledge of the Java standard library. Proficiency in a development environment IDE used for building Java applications (e.g., Eclipse, NetBeans) is required. This training does not cover user interface development.

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.
