Dear all,
On my Web Pen test, I have seen one application that relies on the NTLM
Auth for the authorization. The thing is I have seen many people rely on
the NTLM Authentication to segregate access at the file level but not at
the business logic level.
So yesterday, I have seen one application that uses NTLM authorization
to segregate user access at the business logic layer.
What I mean by that is that instead of using cookies and session ID,
Say that test.ASP has menu A, B and C.
User X can access Menu A, B and C on and the test.ASP
And
User Y can access Menu A, B on the test.ASP by using NTLM Authentication
for the authorization.
I would have thought that this provides more secure environment compared
to the form authentication by cookies, etc. As for accessing the pages
it will do challenge response thingy... However, I think the down side
for this app is that it will be traffic intensive and it is not good
design for traffic intensive application especially when the bandwidth
is an issue.
Any Thought About this particular design?
