Java Performance Training Course

This training empowers participants to understand the specific applications of selected concepts, the fundamental challenges encountered when using them, and the role of the application model. The course also covers essential knowledge regarding the language's standard library functions. Attendees must be familiar with the Integrated Development Environment (IDE) used for building Java applications, such as Eclipse or NetBeans. Please note that this training does not cover user interface (UI) development.

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

In addition to introducing the security components of Standard Java Edition, this course addresses security challenges within Java Enterprise Edition (JEE) and web services. The discussion of specific services is grounded in the fundamentals of cryptography and secure communication. Through a series of practical exercises, participants explore declarative and programmatic security techniques in JEE, as well as transport-layer and end-to-end security for web services. This approach allows participants to apply the discussed APIs and tools hands-on.

The course also examines and explains the most common and severe programming flaws in the Java language and platform, alongside web-related vulnerabilities. Beyond typical errors made by Java programmers, the covered security vulnerabilities address both language-specific issues and problems arising from the runtime environment. These vulnerabilities and their associated attacks are demonstrated through accessible exercises, followed by recommended coding guidelines and mitigation strategies.

Participants attending this course will

• Grasp the fundamental concepts of security, IT security, and secure coding.
• Learn about web vulnerabilities beyond the OWASP Top Ten and understand how to prevent them.
• Comprehend the security concepts underlying web services.
