This section describes how to monitor all incoming/outgoing http requests on both client or web server side. The purpose of this testing is to verify if there is unnecessary or suspicious http request sending in the background.
Most of Web security testing tools (i.e. AppScan, BurpSuite, ZAP) act as Http Proxy. This will require changes of proxy on client side application or browser. The testing techniques listed below is primary focused on how we can monitor Http requests without changes of client side which will be more close to production usage scenario.
1. Monitor all incoming and outgoing http requests to the Web Server to inspect any suspicious requests.
2. Monitor http traffic without changes of end user Browser proxy or client-side application.
How to Test
There is situation that we would like to monitor all http incoming requests on web server side but we can't change configuration on browser or application client side. In this scenario, we can setup reverse proxy on web server side to monitor all incoming/outgoing requests on web server side.
For windows platform, Fiddler is recommended. It provides not only monitor but can also edit/reply the http requests. Refer the refernece for how to configure fiddler as reverse Proxy.
For Linux platform, Charles Web Debugging Proxy may be used.
TCP-level Network Traffic Capture
This technique monitor all the network traffic at TCP-level. TCPDump or WireShark tools can be used. However, these tools don't allow us edit the captured traffic and send modified http requests for testing.
