  26. Question 16. Explain Impersonation?

    Answer :

    At times users access a resource as though they were someone else. This is known as impersonation. For example, if a web page has no access controls, then any user can access that web page. HTML pages, ASP pages, and components in version 3.0 and earlier can be accessed through two accounts named IUSR_machinename and IWAM_machinename. Both the accounts are set up during IIS installation, and are automatically added to all the folders in every web site on the server.

    Anonymous access to a resource in IIS makes the task of identifying a user extremely difficult. But there is no need to authenticate a user in the case of IIS. When IIS receives a request for a web page or other resource that has permission for anonymous access, IIS treats the IUSR_machinename account as the user’s account, to access the resources. If the resource requested by the user is an ASP page that uses a COM or COM+ component, that component is executed using the IWAM_machinename account.
