Even seasoned developers do not necessarily master all the security services provided by their development platforms, nor are they always fully aware of the vulnerabilities that could affect their projects. This course is designed for developers working with both Java and PHP, equipping them with the essential skills needed to make their applications resilient against modern internet-based attacks.

Participants will navigate the layers of Java security architecture, addressing access control, authentication, authorization, secure communication, and various cryptographic functions. The course also introduces key APIs for securing PHP code, such as OpenSSL for cryptography and HTML Purifier for input validation. Server-side best practices for hardening and configuring the operating system, web container, file system, SQL server, and PHP itself are covered, with a special emphasis on client-side security issues related to JavaScript, Ajax, and HTML5.

General web vulnerabilities are discussed using examples aligned with the OWASP Top Ten, including various injection attacks, script injections, session handling attacks, insecure direct object references, file upload issues, and more. The course introduces language-specific problems in Java and PHP, as well as issues arising from the runtime environment, categorizing them into standard vulnerability types such as missing or improper input validation, incorrect use of security features, flawed error and exception handling, time- and state-related problems, code quality issues, and mobile code-related vulnerabilities.

Participants will have the opportunity to experiment with the discussed APIs, tools, and configuration effects. Each introduction to vulnerabilities is supported by hands-on exercises that demonstrate the consequences of successful attacks, show how to fix bugs, apply mitigation techniques, and introduce the use of various extensions and tools.

Participants attending this course will

• Understand fundamental concepts of security, IT security, and secure coding
• Learn about web vulnerabilities beyond the OWASP Top Ten and how to avoid them
• Learn about client-side vulnerabilities and secure coding practices
• Learn to utilize various security features within the Java development environment

Developers

This course equips PHP developers with the essential skills needed to fortify applications against modern internet-based threats. The curriculum explores web vulnerabilities through PHP-centric examples that extend beyond the OWASP Top Ten, addressing various injection attacks, script injections, session handling flaws, insecure direct object references, file upload issues, and more. PHP-related vulnerabilities are categorized into standard types such as inadequate or missing input validation, incorrect error and exception handling, misuse of security features, and time- and state-related problems. For the latter, we examine attacks like open_basedir circumvention, denial-of-service via magic floats, and hash table collision attacks. In every scenario, participants will learn critical techniques and functions to mitigate these risks.

A significant emphasis is placed on client-side security, addressing issues related to JavaScript, Ajax, and HTML5. Several PHP security extensions are introduced, including hash, mcrypt, and OpenSSL for cryptography, as well as Ctype, ext/filter, and HTML Purifier for input validation. Comprehensive hardening practices are provided for PHP configuration (php.ini settings), Apache, and server infrastructure in general. Additionally, the course offers an overview of diverse security testing tools and techniques available to developers and testers, such as security scanners, penetration testing and exploit kits, sniffers, proxy servers, fuzzing tools, and static source code analyzers.

Both the exploration of vulnerabilities and configuration best practices are reinforced with hands-on exercises. These exercises demonstrate the impact of successful attacks, show 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
• Explore web vulnerabilities beyond the OWASP Top Ten and learn how to prevent them
• Understand client-side vulnerabilities and secure coding practices
• Gain practical knowledge of cryptography
• Learn to utilize various PHP security features
• Identify common coding errors and learn how to avoid them
• Stay updated on recent vulnerabilities within the PHP framework
• Acquire practical experience using security testing tools
• Receive resources and further reading materials on secure coding practices
