Here's an issue with IIS 7. NET that I've been researching and getting nowhere with. Any help would be greatly appreciated. My question is: using ASP. How is it that I don't have to explicitly add write access for the application pool user in this case ApplicationPoolIdentity?
Please note that I understand this was probably done for the sake of convenience, since it would be a pain to grant a user access to every folder it needs to write to if you are running under Full Trust.
If you want to limit this access, you can always run the application under Medium Trust. On first glance this may look somewhat worrying, however the Users group has somewhat limited NTFS rights. The ApplicationPoolIdentity still needs to be able to read files from the windows system folders otherwise how else would the worker process be able to dynamically load essential DLL's.
If you take a look at the permissions in the Advanced Security Settings, you'll see the following:. That's the reason your site's ApplicationPoolIdentity can read and write to that folder. In a shared environment where you possibly have several hundred sites, each with their own application pool and Application Pool Identity, you would store the site folders in a folder or volume that has had the Users group removed and the permissions set such that only Administrators and the SYSTEM account have access with inheritance.
You should also ensure that any folders you create where you store potentially sensitive files or data have the Users group removed. So yes, on first glance it looks like the ApplicationPoolIdentity has more rights than it should, but it actually has no more rights than it's group membership dictates.
Find the worker process that is running with the Application Pool Identity you're interested in you will have to add the User Name column to the list of columns to display:. Right clicking on properties for the process and selecting the Security tab we see:. Open up your Users folder and see what application pool folders are there, right click, and check their rights for the application pool virtual account assigned. So that type of file storage access is automatically done and you should be able to write whatever you like there in the app pools user account folders without changing anything.
That's why virtual user accounts for each application pool were created. In the end I had to give the Windows Everyone group read access to that folder to get it to work properly. Learn more.

Do you know how to fix it?Whether you are running your site on your own server or in the cloudsecurity must be at the top of your priority list. If so, you will be happy to hear that IIS has a security feature called the application pool identity.
An application pool identity allows you to run an application pool under a unique account without having to create and manage domain or local accounts. The name of the application pool account corresponds to the name of the application pool. The image below shows an IIS worker process W3wp. Worker processes in IIS 6. Network Service is a built-in Windows identity.
It doesn't require a password and has only user privileges; that is, it is relatively low-privileged. Running as a low-privileged account is a good security practice because then a software bug can't be used by a malicious user to take over the whole system. However, a problem arose over time as more and more Windows system services started to run as Network Service. This is because services running as Network Service can tamper with other services that run under the same identity.
The Windows operating system provides a feature called "virtual accounts" that allows IIS to create a unique identity for each of its application pools. If you are running IIS 7. For every application pool you create, the Identity property of the new application pool is set to ApplicationPoolIdentity by default. The IIS Admin Process WAS will create a virtual account with the name of the new application pool and run the application pool's worker processes under this account by default.
To use this virtual account when running IIS 7. Here is how:. Open the Application Pools node underneath the machine node. Select the application pool you want to change to run under an automatically generated application pool identity. Select the Identity list item and click the ellipsis the button with the three dots. Select the Built-in account button, and then select the identity type ApplicationPoolIdentity from the combo box. To do the same step by using the command-line, you can call the appcmd command-line tool the following way:.
Whenever a new application pool is created, the IIS management process creates a security identifier SID that represents the name of the application pool itself.
From this point on, resources can be secured by using this identity. However, the identity is not a real user account; it will not show up as a user in the Windows User Management Console.
By doing this, the file or directory you selected will now also allow the DefaultAppPool identity access. The following example gives full access to the DefaultAppPool identity. On Windows 7 and Windows Server R2, and later versions of Windows, the default is to run application pools as the application pool identity. To make this happen, a new identity type with the name "AppPoolIdentity" was introduced. With every other identity type, the security identifier will only be injected into the access token of the process.
If the identifier is injected, content can still be ACLed for the ApplicationPoolIdentity, but the owner of the token is probably not unique. Using the Network Service account in a domain environment has a great benefit. Worker process running as Network Service access the network as the machine account. Machine accounts are generated when a machine is joined to a domain. They look like this:. The nice thing about this is that network resources like file shares or SQL Server databases can be ACLed to allow this machine account access.Ayala and Hazon, Kenya Iceland Complete, September 2007 Dear Maria, It's been a week since we came back home, and we still haven't recover from this great experience.
