About Application Security(Code Access Security). It dosn't show correct output

[Tony Johansson]

Hi

I have the program below which is from Microsoft Press exam 70-536
When I run this program I get this output
C:\>listpermissions.exe
System.Security.Permissions.FileIOPermission: True
System.Security.Permissions.EnvironmentPermission: True
System.Security.Permissions.FileDialogPermission: True
System.Security.Permissions.IsolatedStorageFilePermission: True
System.Security.Permissions.ReflectionPermission: True
System.Security.Permissions.UIPermission: True
System.Drawing.Printing.PrintingPermission: True

If I run the program in this way I got the same output.
C:\>\\127.0.0.1\c$\listpermissions.exe
System.Security.Permissions.FileIOPermission: True
System.Security.Permissions.EnvironmentPermission: True
System.Security.Permissions.FileDialogPermission: True
System.Security.Permissions.IsolatedStorageFilePermission: True
System.Security.Permissions.ReflectionPermission: True
System.Security.Permissions.UIPermission: True
System.Drawing.Printing.PrintingPermission: True

According to the book I should get false for some of them because when I run
by using 127.0.0.1 it being run from a shared folder, so it is running from
Internet zone
but as you saw I get the same output whether I run it like this
C:\>listpermissions.exe or this C:\>\\127.0.0.1\c$\listpermissions.exe
The permission that the Internet_zone has is
File Dialog
Isolated Storage
Security
User Interface
Printing

class Program
{
static void Main(string[] args)
{
writePermissionState(new
FileIOPermission(PermissionState.Unrestricted));
writePermissionState(new
EnvironmentPermission(EnvironmentPermissionAccess.Read, "USERNAME"));
writePermissionState(new
FileDialogPermission(FileDialogPermissionAccess.Open));
writePermissionState(new
IsolatedStorageFilePermission(PermissionState.Unrestricted));
writePermissionState(new
ReflectionPermission(ReflectionPermissionFlag.MemberAccess));
writePermissionState(new
UIPermission(UIPermissionWindow.SafeTopLevelWindows));
writePermissionState(new
PrintingPermission(PrintingPermissionLevel.SafePrinting));
Console.WriteLine("\nPress Enter key to continue");
Console.Read();
}

static private void writePermissionState(CodeAccessPermission p)
{
// Write True or False depending on whether the user has the
permission
Console.WriteLine(p.GetType().ToString() + ": " +
SecurityManager.IsGranted(p));
}
}

Does anyone has some suggestion why the output is the same it shouldn't be ?

are you sure 127..0.0.1 is in the internet zone on your pc instead of local
intranet?

are you sure 127..0.0.1 is in the internet zone on your pc instead of
local
intranet?

How do I check if it's in the Internet zone or the local internet ?
I mean to judge from the output it would be the local internet and not the
Internet zone.

So why do the book says that it would be the Internet zone ?
Is it possible to configure so 127.0.0.1 would be the Internet zone ?

Hello Tony,

How do I check if it's in the Internet zone or the local internet ?

the
Internet zone.

possible to configure so 127.0.0.1 would be the Internet zone ?
