How is Burp and ZAP used in Penetration Testing?

Depending on the different features each of these tools provide, they are used differently for penetration testing, along with their similarities of course. In this section, we will take a closer look at Burp versus ZAP for penetration testing.

How is Burp Suite Pro used in Penetration Testing?

Burp Suite Pro allows penetration testers to intercept and modify requests and responses between the browser and server using intercepting proxy. This feature is essential for identifying vulnerabilities such as SQL injection and cross-site scripting (XSS), as it allows testers to manipulate parameters and payloads. Penetration testers can set up a proxy to install a certificate and configure the browser to use the proxy. Then, testers interact with the application using the browser, and the proxy intercepts the requests made by the browser. Testers can then select the intercepted requests to review and attempt to manually test, such as by tampering with or modifying the requests.

Burp Suite Pro also provides a suite of tools for manual testing, including an HTTP editor, repeater, and intruder, which can be used to perform targeted attacks against specific components of the application.

Burp Suite Pro’s scanner uses a combination of passive and active techniques to identify potential vulnerabilities. The scanner can also be customized to use specific scan policies and exclude certain areas of the application from testing. This helps penetration testers stick to the scope of the test. Burp provides an API and supports the development of plugins, which can be used to extend the tool's functionality and automate certain tasks. This can be particularly useful for repetitive tasks, such as scanning multiple applications with the same scan policy.

While Burp Suite Pro does have a scanner included, it still requires the tester to manually verify the results. Burp Suite Pro has some advantages over other tools, including OWASP ZAP. For example, it has an invisible proxy feature, which is niche but not found in Zap. The tool has better capabilities for scanning, and can sometimes find more classes of vulnerabilities than OWASP ZAP. Additionally, Burp’s session handling is better than ZAP.

How is OWASP ZAP used in Penetration Testing?

OWASP ZAP allows testers to quickly identify security vulnerabilities in web applications. It also provides advanced features for experienced testers to conduct in-depth security testing of web applications.

In penetration testing, ZAP can be used to intercept HTTP/HTTPS requests between a web browser and the web server, much like Burp Suite Pro. It allows testers to analyze and modify the requests and responses and identify any security vulnerabilities.

ZAP's automated scanner has a wide range of settings, allowing testers to customize the scans according to specific requirements. It also provides advanced features such as active and passive scanning modes, fuzz testing, and spidering, which can help testers find and exploit security vulnerabilities more effectively. Additionally, ZAP is highly extensible, with a range of add-ons available that can extend its functionality, making it a highly versatile tool for penetration testing.

ZAP includes fuzzing capability, which involves sending large amounts of random or semi-random data to an application in an attempt to trigger unexpected behavior or vulnerabilities. ZAP can be configured to fuzz specific parameters or request fields, and includes a number of built-in fuzzing payloads that can be customized or extended by the tester. Another useful feature of ZAP is its ability to generate reports that summarize the results of a penetration test. These reports can be customized to include specific information or exclude certain details, and can be exported in various formats for sharing with other team members or clients.

However, ZAP does have its limitations. For instance, it has poor loading optimization when loading session files and can be memory-hungry. Additionally, ZAP's user interface can be unintuitive, and there is less community support compared to Burp Suite Pro.

Conclusion

Both Burp Suite Pro and OWASP ZAP are powerful tools that offer a wide range of features for penetration testing. While Burp Suite Pro is a commercial tool with advanced scanning capabilities, it can be expensive for small businesses and individuals. On the other hand, OWASP ZAP is a free and open-source tool that provides a comprehensive suite of scanning and reporting capabilities.

Ultimately, the choice between Burp Suite Pro and OWASP ZAP comes down to individual preferences and requirements. For those who require a highly advanced and customizable tool with premium support and training, Burp Suite Pro is an excellent choice. However, for those who are on a budget and require a comprehensive and free tool, OWASP ZAP is a great option.

It is important to note that neither of these is a magic solution for finding all possible security vulnerabilities. Penetration testers still need to have a good understanding of web application security, testing methodologies, and the ability to think creatively in order to maximize the effectiveness of these tools.
