Combined Java, PHP and Web Application Security

 

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, 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.
