Java Performance Training Course

This training equips participants with a deep understanding of specific Java features, the common challenges associated with their usage, and their role within application architectures. The curriculum also covers essential knowledge regarding the Java standard library functions. Participants are expected to have prior familiarity with an Integrated Development Environment (IDE) used for building Java applications, such as Eclipse or NetBeans. Please note that this course does not cover user interface development topics.

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

In addition to introducing the security components of the Standard Java Edition, this course addresses security issues within Java Enterprise Edition (JEE) and web services. Before diving into specific services, the course covers the foundations of cryptography and secure communication. Through various exercises, participants will explore declarative and programmatic security techniques in JEE, as well as both transport-layer and end-to-end security for web services. Practical exercises allow participants to experiment with the discussed APIs and tools firsthand.

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

Participants attending this course will

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