Is It Possible To Prevent File Access Outside The Website Folder While Keeping Full Trust
Jan 4, 2011
Setting the .Net trust level to Medium on a site will ensure that no code can access files outside the application directory.
I have an ASP.Net site that must run in Full Trust. I have configured my website in IIS to use its own Application Pool Identity [URL].
Currently it is possible for scripts/code in this app to read files outside of the application directory. This occurs because by default, accounts that are a member of the BUILTINusers group are able to read most files on the system, including c: and c:windows. It appears that Applicaion Pool Identity accounts are also members of BUILTINusers.
Is it possible to prevent file access outside the website folder while keeping Full Trust?
I am getting security exceptions since I am using ajax control tool kit I am falling into security exceptions. So I want to set full trust to the folder on my serverso when I use the below command I am getting ERROR: Invalid Label Or Name error. ( I am typing this command from my local machine)
I've been told by my host that I need to enable FullTrust in my webmatrix website because I keep getting an error. (BUT, I have used a different host, and everything on my site works perfectly with them without modification). Anyway, I used the code my host suppllies in their KB, but that just generates a different error. So I looked up full trust on google and used about 5 different code samples to enable full trust but they all generate errors! even the ones on MSDN. And googling "Full Trust WebMatrix" doesn't really bring anything helpful either.
How can I successfully add full trust to a web.config file that is made using WebMatrix?

I'm trying to do what I thought was a simple HttpWebRequest (the code is deep inside a dll so I can't give a small code snippet, but it should be relatively simple), but I'm getting a security exception:
System.Security.SecurityException: Request for the permission of type 'System.Net.WebPermission, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.
I've checked and everything is running with Full trust, and have tried setting this in the web.config. But I've no idea what could be creating the error.

Currently I have written the Activex Control for RFID USB reader and calling that one in ASP.NET web application. The Activex Control is working fine when I will give the full trust permission for particular IIS URL in
1. Open Control Panel > Administrative Tools > .NET Framework 2.0 Configuration
4. Create a new code group, I named mine MyProject_FullTrust_Zone
5. Choose the URL condition type and specify the path on the network where the apps will be deployed.
6. Choose Use Existing permission set, and set it to Full Trust.
Alternative way of giving permission for an Activex Control is
1. Open Visual Studio Command Prompt
2. Run the command caspol -machine -addgroup 1. -site <ip address> FullTrust Doing this it works fine.
Whenever my web site will open, it will ask the user to give permission for the Activex Control using Allow or Cancel Button in browser. This type of functionality I have seen some web site which takes input from the user to allow the ActiveX Control.

I want to read some information from an xml file and store it ready in memory so that it can go out with every page response without being reloaded from the xml on every request.
What is the best way of doing this?
It looks to me like there are 2 options. Either create a class with static fields that the information is stored in. Or create a class with public fields that the info is stored in and create an instance of that class at application level.
Is that correct, are both of those options viable? or will I not be able to access the fields in the second method without creating an instance of the class in the code that responds to the page request(basically if you create an instance of a class at application level can you use that instance from within code anywhere in your website as long as it is public)?
