Description

The Java language and the Runtime Environment (JRE) was designed to be free from the most problematic common security vulnerabilities experienced in other languages, like C/C++. Yet, software developers and architects should not only know how to use the various security features of the Java environment (positive security), but should also be aware of the numerous vulnerabilities that are still relevant for Java development (negative security).

The introduction of security services is preceded with a brief overview of the foundations of cryptography, providing a common baseline for understanding the purpose and the operation of the applicable components. The use of these components is presented through several practical exercises, where participants can try out the discussed APIs for themselves.

The course also goes through and explains the most frequent and severe programming flaws of the Java language and platform, covering both the typical bugs committed by Java programmers and the language- and environment-specific issues. All vulnerabilities and the relevant attacks are demonstrated through easy-to-understand exercises, followed by the recommended coding guidelines and the possible mitigation techniques.

Participants attending this course will

- Understand basic concepts of security, IT security and secure coding
- Learn Web vulnerabilities beyond OWASP Top Ten and know how to avoid them
- Learn to use various security features of the Java development environment
- Have a practical understanding of cryptography
- Learn about typical coding mistakes and how to avoid them

Description

Beyond solid knowledge in using Java components, even for experienced Java programmers it is essential to have a deep knowledge in web-related vulnerabilities both on server and client side, the different vulnerabilities that are relevant for web applications written in Java, and the consequences of the various risks.

General web-based vulnerabilities are demonstrated through presenting the relevant attacks, while the recommended coding techniques and mitigation methods are explained in the context of Java with the most important aim to avoid the associated problems. In addition, a special focus is given to client-side security tackling security issues of JavaScript, Ajax and HTML5.

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.

This course targets developers using both Java and PHP, providing them essential skills necessary to make their applications resistant to contemporary attacks through the Internet.

Levels of Java security architecture are walked through by tackling access control, authentication and authorization, secure communication and various cryptographic functions. Various APIs are also introduced that can be used to secure your code in PHP, like OpenSSL for cryptography or HTML Purifier for input validation. On server side, the best practices are given for hardening and configuring the operating system, the web container, the file system, the SQL server and the PHP itself, while a special focus is given to client-side security through security issues of JavaScript, Ajax and HTML5.

General web vulnerabilities are discussed by examples aligned to the OWASP Top Ten, showing various injection attacks, script injections, attacks against session handling, insecure direct object references, issues with file uploads, and many others. The various Java- and PHP-specific language problems and issues stemming from the runtime environment are introduced grouped into the standard vulnerability types of missing or improper input validation, improper use of security features, incorrect error and exception handling, time- and state-related problems, code quality issues and mobile code-related vulnerabilities.
