Hi all.
I am new to ASP.NET and its security framework.
Have used Site Server for security purposes in the past.
2 concerns I have while implementing our ASP.Net site using Forms
Authentication.
1. I find strange that the the actual credential authentication is
decoupled from
the authentication ticket (cookie) creation (and redirection). That is,
it is possible
to call FormsAuthentication.RedirecFromLoginPage and allow
access without really having to call FormsAuthentication.Authenticate to
verify
credentials. Seems to me like a less secure system than if the 2 steps
were coupled.
Again, being new to this, this just gives me an uneasy feeling. Unless
there is something
that I'm failing to see. Maybe there is another way to enforce that the
authentication cookie
creation doesn't happen unless the credentials have been verified first
against the credential
store.
2. The other thing I find strange (again I'm a newbie) is why by default,
only aspx content is
protected with forms authentication. If I have other files (like htm
or gif) in my secure
content folder, these are not protected. I have to go map the file's
extensions to use the
asp.net dll before they can become protected. Seems contrary to the
'lock everything
first and open up as needed' security premise. Is this because of
performance issues?
Is there a way to have all files be secured by default? Something such
as mapping *.*
to the aspnet.dll in the web mappings so everything is protected.
Again, maybe there
is something I am failing to see.
Any comments to help set me straight would be appreciated.
thanks in advance.
