Java Performance Training Course

Participants will gain an understanding of the specific applications of key concepts, the fundamental challenges associated with their implementation, and their role within the application architecture. The curriculum also covers essential knowledge of the standard library functions. Attendees are expected to have prior familiarity with the IDE environment used for developing Java applications (e.g., Eclipse, NetBeans). Please note that this course does not cover user interface design topics.

Even seasoned Java developers do not necessarily master all the security services provided by Java, nor are they always aware of the various vulnerabilities relevant to web applications built with Java.

In addition to introducing the security components of the Standard Java Edition, this course addresses security issues within the Java Enterprise Edition (JEE) and web services. The discussion of specific services begins with the fundamentals of cryptography and secure communication. Various exercises cover declarative and programmatic security techniques in JEE, as well as both transport-layer and end-to-end security for web services. The use of all components is illustrated through several practical exercises, allowing participants to explore the discussed APIs and tools themselves.

The course also reviews and explains the most frequent and severe programming flaws of the Java language and platform, as well as web-related vulnerabilities. Beyond the 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 relevant attacks are demonstrated through easy-to-understand exercises, followed by recommended coding guidelines and possible mitigation techniques.

Participants attending this course will

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