Even experienced Java programmers are not mastering by all means the various security services offered by Java, and are likewise not aware of the different vulnerabilities that are relevant for web applications written in Java.

The course – besides introducing security components of Standard Java Edition – deals with security issues of Java Enterprise Edition (JEE) and web services. Discussion of specific services is preceded with the foundations of cryptography and secure communication. Various exercises deal with declarative and programmatic security techniques in JEE, while both transport-layer and end-to-end security of web services is discussed. The use of all components is presented through several practical exercises, where participants can try out the discussed APIs and tools for themselves.

The course also goes through and explains the most frequent and severe programming flaws of the Java language and platform and web-related vulnerabilities. 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.

Even experienced programmers do not master by all means the various security services offered by their development platforms, and are likewise not aware of the different vulnerabilities that are relevant for their developments. 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.

Participants can try out the discussed APIs, tools and the effects of configurations for themselves, while the introduction of vulnerabilities are all supported by a number of hands-on exercises demonstrating the consequences of successful attacks, showing how to correct the bugs and apply mitigation techniques, and introducing the use of various extensions and tools.

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.
