**Course Title:** Security Best Practices in Software Development **Section Title:** Security Testing Techniques **Topic:** Conduct a penetration test on a sample web application. (Lab topic) **Objective:** In this lab, you will learn to conduct a penetration test on a sample web application, identify vulnerabilities, and exploit them using various tools and techniques. This hands-on experience will help you understand the importance of security testing in software development. **Pre-requisites:** * Familiarity with penetration testing concepts and tools * Understanding of web application security fundamentals * Completed previous lab exercises (Static Application Security Testing (SAST) vs. Dynamic Application Security Testing (DAST) and Introduction to security testing methodologies) **Lab Environment:** For this lab, we will be using a sample web application called "DVWA" (Damn Vulnerable Web Application). DVWA is a deliberately vulnerable web application designed for training purposes. You can download and install it on your local machine or use a pre-installed version in a virtual lab environment. **Lab Objective:** Conduct a penetration test on the DVWA web application and identify vulnerabilities in the following areas: 1. SQL Injection 2. Cross-Site Scripting (XSS) 3. Cross-Site Request Forgery (CSRF) 4. Authentication and Authorization **Lab Steps:** **Step 1: Reconnaissance** * Launch the DVWA application and explore the website. * Identify the entry points, such as login forms, search bars, and URL parameters. * Use tools like Burp Suite or ZAP to intercept and analyze HTTP requests and responses. **Step 2: SQL Injection** * Use Burp Suite or ZAP to fuzz the login form and detect potential SQL injection vulnerabilities. * Use tools like SQLmap to inject malicious SQL queries and extract sensitive data. * Analyze the database schema and identify sensitive data. **Step 3: Cross-Site Scripting (XSS)** * Use Burp Suite or ZAP to fuzz the search bar and detect potential XSS vulnerabilities. * Use tools like BeEF (Browser Exploitation Framework) to inject malicious JavaScript code and take control of the user's browser. * Analyze the application's input validation and sanitization mechanisms. **Step 4: Cross-Site Request Forgery (CSRF)** * Use Burp Suite or ZAP to detect potential CSRF vulnerabilities in the application's forms and actions. * Use tools like OWASP's CSRFTester to test and exploit CSRF vulnerabilities. * Analyze the application's CSRF protection mechanisms. **Step 5: Authentication and Authorization** * Use Burp Suite or ZAP to analyze the application's authentication and authorization mechanisms. * Use tools like Hydra or Medusa to brute-force login credentials. * Analyze the application's password policies and storage mechanisms. **Step 6: Reporting and Exploitation** * Document all the vulnerabilities identified during the penetration test. * Provide recommendations for remediating the identified vulnerabilities. * Exploit the vulnerabilities using various tools and techniques to demonstrate their impact. **Lab Resources:** * DVWA web application: [https://github.com/digininja/DVWA](https://github.com/digininja/DVWA) * Burp Suite: [https://portswigger.net/burp](https://portswigger.net/burp) * ZAP: [https://www.zaproxy.org/](https://www.zaproxy.org/) * SQLmap: [http://sqlmap.org/](http://sqlmap.org/) * BeEF: [http://beefproject.com/](http://beefproject.com/) * OWASP's CSRFTester: [https://github.com/OWASP/CSRFTester](https://github.com/OWASP/CSRFTester) * Hydra: [https://github.com/vanhauser-thc/thc-hydra](https://github.com/vanhauser-thc/thc-hydra) * Medusa: [https://github.com/jmk-foofus/medusa](https://github.com/jmk-foofus/medusa) **Conclusion:** In this lab, you have conducted a penetration test on a sample web application and identified vulnerabilities in various areas. You have used various tools and techniques to exploit these vulnerabilities and demonstrate their impact. This hands-on experience has highlighted the importance of security testing in software development and the need for continuous vulnerability assessment and remediation. **What's Next?** In the next topic, we will explore "Understanding firewalls, intrusion detection systems (IDS), and intrusion prevention systems (IPS)" from the Network Security Fundamentals section. **Call to Action:** * Leave a comment below if you have any questions or need help with the lab exercise. * Share your experience with the lab exercise and any challenges you faced. * Ask for feedback from your peers and instructors. Remember to stay tuned for the next topic and continue your journey in learning Security Best Practices in Software Development.
