Java Performance Training Course

In this training, participants will learn the specific use cases for selected Java features, understand the common challenges encountered when using them, and grasp their role within the application model. The course also covers fundamental knowledge of standard library functions. Attendees are expected to have prior experience with an Integrated Development Environment (IDE) such as Eclipse or NetBeans for building Java applications. Please note that this training does not cover user interface development.

Even seasoned Java developers do not necessarily master the full range of security services provided by Java, nor are they always aware of the various vulnerabilities that can affect web applications built with Java.

In addition to introducing the security components of the Standard Java Edition, this course addresses security concerns within Java Enterprise Edition (JEE) and web services. The discussion of specific services begins with the fundamentals of cryptography and secure communication. A variety of exercises cover both declarative and programmatic security techniques in JEE, while the course examines transport-layer and end-to-end security for web services. Through several practical exercises, participants gain hands-on experience with the discussed APIs and tools.

The course also reviews and explains common and severe programming flaws in the Java language and platform, as well as web-related vulnerabilities. Beyond typical errors made by Java developers, the covered security vulnerabilities include both language-specific issues and problems arising from the runtime environment. All vulnerabilities and their corresponding attacks are demonstrated through easy-to-understand exercises, followed by recommended coding guidelines and possible mitigation techniques.

Participants attending this course will

• Understand fundamental concepts of security, IT security, and secure coding
• Learn about web vulnerabilities beyond the OWASP Top Ten and know how to avoid them
• Understand the security concepts underlying web services
• Learn to utilize various security features within the Java development environment
