**Course Title:** Testing Frameworks: Principles and Practices **Section Title:** Security Testing **Topic:** Implement security tests to identify vulnerabilities in a sample application. (Lab topic) **Lab Overview:** In this hands-on lab, we will walk you through the process of implementing security tests to identify vulnerabilities in a sample application. We will use a combination of tools and techniques to demonstrate how security testing can be incorporated into your testing workflow. By the end of this lab, you will have a better understanding of how to identify and exploit common security vulnerabilities, and how to use security testing tools to improve the security posture of your application. **Lab Objectives:** * Understand how to use security testing tools to identify vulnerabilities in an application * Learn how to implement security tests for common security vulnerabilities such as SQL injection and cross-site scripting (XSS) * Understand how to use tools such as OWASP ZAP and Burp Suite to identify security vulnerabilities * Learn how to write security tests using a testing framework such as JUnit or NUnit **Lab Environment:** For this lab, you will need to have the following tools installed on your system: * A sample application (provided below) * OWASP ZAP (https://www.zaproxy.org/) * Burp Suite (https://portswigger.net/burp/) * JUnit or NUnit (depending on your preferred testing framework) * A Java or .NET development environment (depending on the sample application) **Sample Application:** For this lab, we will be using a sample application called "Vulnerable App" (https://github.com/OWASP/Goat). This application is designed to be intentionally vulnerable to a variety of security threats, and is a great tool for learning about security testing. **Lab Steps:** **Step 1: Setting up the Sample Application** Download and install the Vulnerable App on your system. Follow the instructions provided with the application to get it up and running. **Step 2: Setting up OWASP ZAP and Burp Suite** Download and install OWASP ZAP and Burp Suite on your system. Follow the instructions provided with the tools to get them up and running. **Step 3: Identifying Security Vulnerabilities with OWASP ZAP** Launch OWASP ZAP and configure it to scan the Vulnerable App. Follow the instructions provided with OWASP ZAP to identify security vulnerabilities such as SQL injection and XSS. **Step 4: Implementing Security Tests for SQL Injection** Using your preferred testing framework (JUnit or NUnit), write a security test to identify SQL injection vulnerabilities in the Vulnerable App. Use the test to demonstrate how SQL injection attacks can be exploited. **Step 5: Implementing Security Tests for Cross-Site Scripting (XSS)** Using your preferred testing framework (JUnit or NUnit), write a security test to identify XSS vulnerabilities in the Vulnerable App. Use the test to demonstrate how XSS attacks can be exploited. **Step 6: Using Burp Suite to Identify Security Vulnerabilities** Launch Burp Suite and configure it to scan the Vulnerable App. Follow the instructions provided with Burp Suite to identify security vulnerabilities such as authentication and authorization issues. **Step 7: Writing Security Tests for Authentication and Authorization Issues** Using your preferred testing framework (JUnit or NUnit), write a security test to identify authentication and authorization issues in the Vulnerable App. Use the test to demonstrate how these issues can be exploited. **Lab Conclusion:** By the end of this lab, you should have a better understanding of how to implement security tests to identify vulnerabilities in a sample application. You should also have practical experience using tools such as OWASP ZAP and Burp Suite to identify security vulnerabilities, and writing security tests using a testing framework such as JUnit or NUnit. **Additional Resources:** If you would like to learn more about security testing and its importance, we recommend checking out the following resources: * OWASP Security Testing Guide (https://owasp.org/www-project-security-testing-guide/) * OWASP ZAP User Guide (https://www.zaproxy.org/docs/) * Burp Suite User Guide (https://portswigger.net/burp/userguide) **Leave a comment or ask for help:** If you have any questions or need help with the lab, please leave a comment below. We will do our best to respond promptly and assist you with any issues you may be experiencing. **Next Topic:** In the next topic, we will cover "Writing maintainable and scalable tests." This topic will provide you with tips and best practices for writing tests that are easy to maintain and scale as your application grows.
