1. The Burp Proxy (The Core)

The Proxy is the most famous part of Burp. It sits between the Client (Browser) and the Server. When you click a button on a website, Burp "pauses" the request. You can then change the data (like prices or user IDs) before letting it reach the server.

2. Key Components of Burp Suite

Tool Name Function
RepeaterManually modify and re-send individual web requests to test server responses.
IntruderAutomate customized attacks (like Brute Forcing passwords or Fuzzing).
DecoderEncode or Decode data (Base64, URL, Hex) instantly.
ScannerAutomated vulnerability scanner (Professional version only) for SQLi, XSS, etc.

3. Typical Security Testing Workflow

  • Intercept: Capture a request using the Proxy.
  • Analyze: Review parameters, cookies, and headers for weaknesses.
  • Manipulate: Send the request to Repeater to try different payloads.
  • Exploit: Use Intruder if you need to test thousands of variations quickly.
