Java Performance Training Course

This course equips participants with a deep understanding of selected Java features, the common challenges associated with them, and their role within the application architecture. It also covers essential knowledge of the Java standard library functions. Participants are expected to have prior experience with a Java development IDE (such as Eclipse or NetBeans) used for building applications. Note that this training does not cover user interface (UI) topics.

Even seasoned Java developers often lack a comprehensive grasp of the security services provided by Java and the various vulnerabilities that affect web applications built with it.

This course not only introduces the security components of the Standard Java Edition but also addresses security concerns within Java Enterprise Edition (JEE) and web services. The discussion begins with the fundamentals of cryptography and secure communication before diving into specific services. Various exercises cover both declarative and programmatic security techniques in JEE, as well as transport-layer and end-to-end security for web services. Participants engage in practical exercises to explore and apply the discussed APIs and tools firsthand.

The course also examines and explains the most common and severe programming flaws in the Java language and platform, along with web-related vulnerabilities. Beyond typical bugs made by Java programmers, the security vulnerabilities covered include language-specific issues and problems arising from the runtime environment. All vulnerabilities and associated attacks are demonstrated through accessible exercises, followed by recommended coding guidelines and mitigation techniques.

Participants attending this course will

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