Java Performance Training Course

In this training, participants will learn the specific applications of selected advanced concepts, understand common challenges associated with their usage, and grasp the role of application modeling. The course also covers essential knowledge of the Java Standard Library functions. Attendees are expected to have familiarity with an integrated development environment (IDE) for building Java applications, such as Eclipse or Netbeans. Please note that this training does not cover user interface development.

Even seasoned Java developers often do not fully master the full spectrum of security services provided by Java, nor are they always aware of the diverse vulnerabilities that impact web applications built with Java.

In addition to introducing the security components of Standard Java Edition, this course addresses the security challenges associated with Java Enterprise Edition (JEE) and web services. The discussion begins with the foundational principles of cryptography and secure communication before diving into specific services. Through a series of exercises, participants explore both declarative and programmatic security techniques within JEE, as well as transport-layer and end-to-end security for web services. The practical application of these components is demonstrated through hands-on exercises, allowing participants to experiment with the relevant APIs and tools firsthand.

The course also examines and explains the most common and critical programming flaws in the Java language and platform, alongside web-related vulnerabilities. Beyond typical errors made by Java developers, the covered security vulnerabilities encompass both language-specific issues and problems arising from the runtime environment. All identified vulnerabilities and their corresponding attacks are illustrated through accessible exercises, followed by recommended coding guidelines and effective mitigation strategies.

Participants attending this course will

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