Java Performance Training Course

During this training, participants will learn the specific applications of key concepts, the common challenges associated with them, and their role within the application architecture. The course also covers essential knowledge of the Java Standard Library functions. Participants are expected to be familiar with the Integrated Development Environment (IDE) used to build Java applications, such as Eclipse or NetBeans. Please note that user interface (UI) development is not covered in this training.

Even seasoned Java developers often struggle to fully master the diverse security services provided by Java, and they are frequently unaware of the various vulnerabilities that impact web applications built with Java.

Beyond 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 of specific services is grounded in the fundamental principles of cryptography and secure communication. Participants will engage in various exercises covering declarative and programmatic security techniques in JEE, while also exploring transport-layer and end-to-end security for web services. Through practical exercises, attendees can apply the discussed APIs and tools, gaining hands-on experience with each component.

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. In addition to typical errors made by Java developers, the identified security vulnerabilities encompass both language-specific issues and problems arising from the runtime environment. All vulnerabilities and corresponding attacks are demonstrated through easy-to-understand exercises, followed by recommended coding guidelines and effective mitigation techniques.

Participants attending this course will

• Grasp the core concepts of security, IT security, and secure coding
