Experienced programmers do not always fully master the security features available in their development platforms, nor are they always aware of the vulnerabilities relevant to their specific 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 threats.

The course explores the layers of the Java security architecture by addressing access control, authentication, authorization, secure communication, and various cryptographic functions. It also introduces several APIs available in PHP to help secure code, such as OpenSSL for cryptographic purposes and HTML Purifier for input validation. On the server side, it outlines best practices for hardening and configuring the operating system, web containers, file systems, SQL servers, and PHP itself, while placing special emphasis on client-side security issues related to JavaScript, Ajax, and HTML5.

General web vulnerabilities are discussed through examples aligned with the OWASP Top Ten, covering various injection attacks, script injections, session handling attacks, insecure direct object references, file upload issues, and more. The course also introduces Java- and PHP-specific language problems and issues arising from the runtime environment, categorized 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 have the opportunity to experiment with the discussed APIs, tools, and configuration effects. The introduction of vulnerabilities is supported by numerous hands-on exercises that demonstrate the consequences of successful attacks, show how to correct bugs, apply mitigation techniques, and introduce the use of various extensions and tools.

Participants attending this course will

• Understand the fundamental concepts of security, IT security, and secure coding
• Learn about web vulnerabilities beyond the OWASP Top Ten and know how to avoid them
• Understand client-side vulnerabilities and secure coding practices
• Learn to utilize various security features within the Java development environment
• Gain a practical understanding of cryptography
• Learn to use various security features of PHP
• Understand the security concepts of Web services
• Acquire practical knowledge in using security testing tools
• Learn about typical coding mistakes and how to avoid them
• Be informed about recent vulnerabilities in Java and PHP frameworks and libraries
• Receive resources and further readings on secure coding practices

This course equips PHP developers with the vital skills needed to shield applications from modern internet-based threats. It explores web vulnerabilities through practical PHP examples that extend beyond the OWASP Top Ten, addressing diverse injection attacks, script injection, weaknesses in PHP session handling, insecure direct object references, file upload issues, and more. PHP-specific vulnerabilities are categorized into standard types such as missing or flawed input validation, incorrect error and exception handling, misuse of security features, and time- and state-related issues. For the latter category, we examine attacks like open_basedir circumvention, denial-of-service via magic floats, and hash table collision attacks. Throughout, participants learn the essential techniques and functions required to mitigate these risks.

Special attention is given to client-side security, addressing issues in JavaScript, Ajax, and HTML5. The course introduces key PHP security extensions, including hash, mcrypt, and OpenSSL for cryptography, as well as Ctype, ext/filter, and HTML Purifier for input validation. We cover best hardening practices related to PHP configuration (php.ini settings), Apache, and general server setup. Additionally, an overview of various security testing tools and techniques is provided, enabling developers and testers to utilize security scanners, penetration testing frameworks, exploit packs, sniffers, proxy servers, fuzzing tools, and static source code analyzers.

Both the introduction of vulnerabilities and configuration practices are reinforced by hands-on exercises. These exercises demonstrate the impact of successful attacks, illustrate the application of mitigation techniques, and guide participants through the use of various extensions and tools.

Participants attending this course will

• Comprehend 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 adhere to secure coding practices
• Gain a practical understanding of cryptography
• Learn to utilize various PHP security features
• Identify common coding mistakes and discover how to avoid them
• Stay informed about recent vulnerabilities affecting the PHP framework
• Acquire practical experience with security testing tools
• Access resources and further reading on secure coding practices

Developers

A vast array of proven and reliable patterns are readily accessible to all. Often, the process simply involves adapting the terminology and applying these patterns to specific technologies. This approach can save hundreds of hours that would otherwise be dedicated to design and testing efforts. Training Objectives This course has two primary aims: first, it enables you to leverage widely recognized patterns; second, it empowers you to create and reuse patterns tailored to your organization. It assists you in estimating how patterns can reduce costs, systematize the design process, and generate a code framework based on your patterns. Target Audience Software designers, business analysts, project managers, programmers and developers as well as operational managers and software division managers. Course Style The course focuses on use cases and their relationship with a specific pattern. Most of the examples are explained in UML and in simple Java examples (the language can change if the course is booked as a closed course). It guides you through the sources of the patterns as well as showing you how to catalogue and describe patterns which can be reused across your organization.
