The course introduces security components of Standard Java Edition, which is preceded with the foundations of cryptography, providing a common baseline for understanding the purpose and the operation of the applicable components. The use of all components is presented through practical exercises, where participants can try out the discussed APIs and tools for themselves.
Finally, the course explains the most frequent and severe programming flaws of the Java language and platform. Besides the typical bugs committed by Java programmers, the introduced security vulnerabilities cover both language-specific issues and problems stemming from the runtime environment. All vulnerabilities and the relevant attacks are demonstrated through easy-to-understand exercises, followed by the recommended coding guidelines and the possible mitigation techniques.
