Java Performance Training Course

Participants will learn the specific applications of selected topics, the common challenges associated with their use, and the importance of application models. The course also covers fundamental knowledge of the Java standard library functions. Prior experience with a Java IDE (such as Eclipse or NetBeans) is required. Note that this training does not cover user interface development.

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

Alongside introducing the security components of Standard Java Edition, this course addresses security issues in Java Enterprise Edition (JEE) and web services. Discussions on specific services are grounded in the foundations of cryptography and secure communication. Through various exercises, the course covers declarative and programmatic security techniques in JEE, as well as both transport-layer and end-to-end security for web services. The use of all components is demonstrated through practical exercises, allowing participants to experiment with the discussed APIs and tools firsthand.

The course also examines and explains the most frequent and severe programming flaws in the Java language and platform, as well as web-related vulnerabilities. In addition to typical bugs committed by Java programmers, the security vulnerabilities introduced 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 potential mitigation techniques.

Participants attending this course will

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