Monitoring ISAPI

 

Monitoring ISAPI works for:

 

Native ISAPI extensions.

 

Native ISAPI

 

If you are working with native ISAPI you must use the NT Service API in your service as well as using the Monitor ISAPI method below.

 

To start monitoring ISAPI:

 

menu Launch menu instructionStep IIS menu instructionStep Monitor IIS and ISAPI... instructionStep shows the Monitor ISAPI dialog below

 

or use the shortcut

 

 b_f7  Monitor IIS and ISAPI

 

 

The monitor ISAPI dialog

 

Set the dll to monitor, the web root, the IIS process, an optional web browser to use and an optional url to launch, and click OK.

 

monitor-ISAPI

 

 

ISAPI DLL instructionStep type or Browse to set the ISAPI DLL that we're monitoring
 

IIS web instructionStep type or Browse to set the web root for the IIS website we're working with
 

IIS process to monitor instructionStep select the IIS process we're working with
 

Web Browser instructionStep select the web browser that you're going to use to load the web page
 

URL to open in browser instructionStep type the web page and arguments you want to load to cause the ISAPI to be loaded in IIS

 

OK instructionStepresets IIS, setups all the variables, copies DLLs and settings into the web root and starts the web browser to load the specified web page

 

menu IIS is a protected process and can only execute, read and write files in specific directories. That's why Thread Validator copies data to the web root so that it can be read, written or executed.

 

Data collection

 

Depending on your application, and what you want to validate, you may want to start collecting data as soon as injection has happened, or do it later.

 

If your program has a complex start-up procedure, initialising lots of data, it may be much faster not to collect data until the program has launched.

 

If it's the startup procedure you want to validate, obviously start collecting data immediately.

 

seeAlsoSee the section on controlling data collection for how to turn collection on and off after launch.
