Security :: Restrict Users From Tempering The View-state Value?
Mar 3, 2011
We deployed our usercontrols (gridView, textboxes & button) on sharepoint 2010 site, & everything works fine.
Now testing team are able to alter the viewstate value of controls through Fiddler and changed it with some junk characters, now after submitting
the form to server, it throws Invalid JASON Primitive (server 500 error)
In web.config file, by default EnableViewStateMac is true.
Is it any way to restrict the users or any way to stop the postback if some one alters the viewstate.

I am trying to create a diary site which will allow users to enter rich texts (text, picture and video links...) and the outcome for each page will be an html file being saved under each users profile folder.If I create html files for every user entry, then these pages can be accessible if the path and file name is known for them... I am trying to have some secured html pages so that only the owner of those pages can have access to them after logging in.

I am using the membership provider and am reasonably comfortable that all of my web pages are safe.Some of the pages contain hyperlinks to documents (pdf, xls, etc.) stored in a folder under the root of the web site. I have disabled the ability of users to anonymously list folder contents, but I don't see a way to keep anonymous users from accessing the documents if they know the specific URL for that document. Example; if the document contains a spreadsheet of current sales, I don't want an ex-employee (who captured the URL while working here) to be able to bring up the current document.asswording the documents isn't a good choice because there are hundreds and we'd like to avoid changing them all every time someone leaves, or weekly, or whenever...Is there a way to restrict access to all contents of a web folder to people who have been authenticated?

I have a doubt in creatig user through CreateUserWiward or ASP.NET Configuration. As we know by the way of this we can create user and login the same user into the system alltime. But my question is where the created user is from or where it is stored and how long the users are to be pereserced in that area.
Also Is there any possiblity to view the users other than though ASP.NEt configuration, One more doubt is there any way to interact the same with Database by using CreateUserWiard and Login Control.

Quick question: is it possible to retrive a users certificate store i.e. list all of the client's Personal Certificates?
Just to be clear, I am talking about the certificates installed on the clients machine, not the servers. I have managed to list the server's certificates, but so far have been unsuccesful with the above.

I have an asp.net application. There is a folder in the project that users upload images and files to that folder.
I want to restrict users, that each user sees only his files. How can I do this?
Because files are uploaded in folder, users may access them by browsing file urls.

I'm writing a simple Intranet application using windows authentication. I want to restrict access to Safe/UCantSeeMe.aspx. I am aware of the AuthorizeAttribute, but this only works on methods. I also found a good post on doing this with the MVC pattern, but I'm not using MVC. This can be done with roles in forms based security. I read on MSDN that using windows based security means roles are based on groups, but it doesn't go into any detail. how can I restrict access to Safe/UCantSeeMe.aspx?

First of all, thank you for the attention.
I am having some trouble, I am very new to asp.net, and the last problem I had, I spent about 59 hours trying to solve, Now I have a new one !
:D well, I guess this is part of the learning process...
Well, in Visual Studio 2010, I clicked New Website. @ C# language, ... The template it gives is pretty nice, it creates a database MDF file, and a login/register setup ready to go !...
You guys can see it live AT CLICK HERE ...
Everything is working, well at least here at the local machine...
There are 2 pages in there, Default.aspX, and About.aspx ... I want to allow ONLY logged in users to view those 2 pages... I tryed a few things, added my account to a role called ADMIN,
In the web.cong I changed Allow"*" to allow"ADMIN" ... still didn't work.. Also, I was trying to avoid using roles for now, and I was trying to find a way to do this for individual pages in the same directory as well... If possible with out touching the web.config file...
