Even seasoned programmers do not necessarily master the various security services offered by their development platforms, nor are they always aware of the different vulnerabilities that are relevant to 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 explored 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.

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 client-side vulnerabilities and secure coding practices
• Learn to use various security features of the Java development environment

Developers

This course equips PHP developers with the vital skills needed to shield their applications from modern Internet-based threats. It explores web vulnerabilities through practical PHP examples, extending beyond the OWASP Top Ten to cover a wide array of risks including various injection attacks, script injections, weaknesses in PHP session handling, insecure direct object references, file upload issues, and more. PHP-specific vulnerabilities are categorized into standard vulnerability types such as inadequate or incorrect input validation, flawed error and exception handling, misuse of security features, and time- or state-related problems. Specific attack vectors discussed include open_basedir circumvention, denial-of-service via magic floats, and hash table collision attacks. In each scenario, participants will learn the key techniques and functions required to mitigate these risks.

A significant emphasis is placed on client-side security, addressing issues related to JavaScript, Ajax, and HTML5. The course introduces essential PHP security extensions, such as hash, mcrypt, and OpenSSL for cryptographic purposes, as well as Ctype, ext/filter, and HTML Purifier for robust input validation. Best practices for hardening are provided with respect to PHP configuration (php.ini settings), Apache, and general server administration. Additionally, the course offers an overview of various security testing tools and methodologies available to developers and testers, including security scanners, penetration testing frameworks, exploit packs, sniffers, proxy servers, fuzzing tools, and static source code analyzers.

Both the explanation of vulnerabilities and the discussion of configuration practices are reinforced by hands-on exercises. These activities demonstrate the impact of successful attacks, illustrate how to implement mitigation strategies, and guide participants through the use of various extensions and tools.

Participants attending this course will

• Grasp fundamental concepts of security, IT security, and secure coding
