Design Patterns (GoF) for Java Training Course

Participants in this training will gain an in-depth understanding of specific programming concepts, the common challenges encountered when utilizing them, and their role within the application architecture. The course also covers essential knowledge of the Java Standard Library functions. To succeed, attendees should be familiar with a Java development environment IDE used to build applications (e.g., Eclipse, Netbeans). Please note that this training does not cover user interface design issues.

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

This course, in addition to introducing the security components of Standard Java Edition, addresses security issues within Java Enterprise Edition (JEE) and web services. The discussion of specific services begins with the foundations of cryptography and secure communication. Various exercises focus on declarative and programmatic security techniques in JEE, while both transport-layer and end-to-end security for web services are examined. The application of all components is demonstrated through several practical exercises, allowing participants to experiment with the discussed APIs and tools firsthand.

The course also reviews and explains the most common and severe programming flaws in the Java language and platform, as well as web-related vulnerabilities. Beyond typical errors made by Java programmers, the introduced security vulnerabilities cover both language-specific issues and problems arising from the runtime environment. All vulnerabilities and associated attacks are demonstrated through easy-to-understand exercises, followed by recommended coding guidelines and potential mitigation techniques.
