Design Patterns (GoF) for Java Training Course

In this training, participants will gain a clear understanding of the specific applications of various concepts, the fundamental challenges often encountered when working with them, and the role of application models. The course also covers essential knowledge of the Java standard library functions. Attendees are expected to have prior experience with an Integrated Development Environment (IDE) used for building Java applications, such as Eclipse or NetBeans. Please note that this training does not cover user interface development topics.

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

In addition to introducing the security components of 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. Participants will explore declarative and programmatic security techniques in JEE through various exercises, while also examining both transport-layer and end-to-end security for web services. Practical exercises allow participants to apply these APIs and tools, providing hands-on experience with all discussed components.

The course also covers and explains the most common and severe programming flaws associated with the Java language and platform, as well as web-related vulnerabilities. Beyond typical bugs committed by Java developers, the security vulnerabilities addressed include both language-specific issues and problems arising from the runtime environment. All vulnerabilities and corresponding attacks are demonstrated through clear, understandable exercises, followed by recommended coding guidelines and potential 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
• Understand the security concepts of web services
• Learn to utilize various security features within the Java development environment
