View Web traffic with Burp Suite
Burp Suite is a powerful tool that allows you to view and modify web traffic. With Burp Suite, you can intercept and analyze HTTP and HTTPS traffic between your web browser and the web server, enabling you to identify and fix vulnerabilities in your web applications.
Here are the steps to view web traffic with Burp Suite:
- Set up Burp Suite as a proxy
The first step is to set up Burp Suite as a proxy. This involves configuring your web browser to use Burp Suite as a proxy server. To do this, open Burp Suite and go to the “Proxy” tab. Click on the “Options” tab, and then on the “Proxy listeners” sub-tab. Click on the “Add” button, and select the interface and port that you want to use as the proxy.
Next, configure your web browser to use Burp Suite as a proxy server. The process for doing this will vary depending on the browser you are using. In general, you will need to go to your browser’s settings, find the proxy settings, and enter the IP address and port number of the Burp Suite proxy.
- Intercept web traffic
Once Burp Suite is set up as a proxy, you can start intercepting web traffic. To do this, go to the “Proxy” tab in Burp Suite, and click on the “Intercept” sub-tab. Then, click on the “Intercept is on” button to start intercepting traffic.
When you visit a website in your browser, the traffic will be intercepted by Burp Suite. You can view the intercepted traffic in the “Proxy” tab, under the “Intercept” sub-tab.
- Analyze web traffic
Burp Suite allows you to analyze web traffic in a variety of ways. For example, you can view the raw request and response data, as well as the headers and cookies. You can also view the traffic in a variety of formats, such as text, HTML, and JSON.
You can use Burp Suite to identify vulnerabilities in your web application by looking for common attack patterns, such as SQL injection, cross-site scripting (XSS), and CSRF attacks. You can also use Burp Suite to test the effectiveness of your web application’s security controls, such as authentication and access controls.
- Modify web traffic
Burp Suite also allows you to modify web traffic, which can be helpful in testing your web application’s resilience to attacks. For example, you can modify the request headers or cookies to simulate an attack, and then observe how the application responds.
To modify web traffic, simply select the request or response in the “Proxy” tab, and then right-click and select “Send to Repeater”. This will open the request in the Repeater tool, where you can make modifications and resend the request.
