Java Performance Training Course

Participants in this training will gain insight into the specific applications of selected topics, the fundamental challenges associated with their usage, and the significance of application models. The course also covers essential knowledge regarding the standard library functions of the language. It is assumed that participants have prior knowledge of the Integrated Development Environment (IDE) used for constructing Java applications (such as Eclipse or NetBeans). Please note that this training does not cover user interface design issues.

Even seasoned Java developers do not necessarily master every security service offered by Java, nor are they always aware of the various vulnerabilities relevant to web applications written in Java.

The course, while introducing the security components of Standard Java Edition, also addresses security issues concerning Java Enterprise Edition (JEE) and web services. Before discussing specific services, the course covers the foundations of cryptography and secure communication. Various exercises focus on declarative and programmatic security techniques in JEE, alongside discussions on both transport-layer and end-to-end security for web services. Participants can apply these concepts through practical exercises, allowing them to test out the discussed APIs and tools themselves.

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

Participants attending this course will

• Understand basic concepts of security, IT security, and secure coding
• Learn about web vulnerabilities beyond the OWASP Top Ten and know how to avoid them
• Understand the security concepts of web services
