Security :: Protecting Documents In Application?

Aug 28, 2010

There is an ASP.NET application www.example.com/APP. From within the application several documents - for example office documents DOCX, PDF, etc. - can be opend. They are accessed via some virtual directory as in
www.example.com/APP/VIRTUAL/letter.pdf.

Of course, the documents may only be accessed from within the application, after the user has been identified succssfully. Some documents may only be opened by some privileged users. It should be impossible to open letter.pdf by simply entering the above url into a browser

I am thinking about the following...

The name of the virtual directory is kept secret. After the user has successfully logged into the application, some secret is created. The secret contains the user's ID and some time information (valid from / until). Then, if a document is to be referenced from within the application, the url www.example.com/APP/<secret>/letter.pdf is referenced. In IIS the secret is checked. For this, some of my code is called, when serving a request. If successfull, the url is rewritten as www.example.com/APP/VIRTUAL/letter.pdf. I tried several components, such as the IIS URL Rewrite, IHttpModule, IHttpHandler. Unfortunately, I did not yet succeed.

Security :: Protecting A Folder Using Membership But No Login Control?

Jun 23, 2010

I have a business site that I want to use to show clients their projects I am working on. I don't want these projects to be visible to anyone but the clients, so I give them a user ID and password. I want to use asp.net membership to manage the login IDs and passwords, but I want to use jquery to submit the login form (it's lighter and leaner than the login control). Here is what I have: Page with an html form for login .js file with the jquery calls & code in it httpHandler to process the information from the formI have the user to entering their ID and password, I am using jquery.forms.js to process the form, which calls the httpHandler and passes the form values to the handler. I have the handler check to see if the user ID and password are correct, if not, it passes back a message to be displayed to the user. If the user is valid, then I have it passing back the role of the user, which also happens to be the name of the folder the client needs to view. I have the page redirecting via javascript to the client's folder once they are authenticated. I have the location of the client folder setup in my web.config.

The problem I'm having is the page just redirects back to the login page, with the return url included (?ReturnUrl=%2fCTS%2f2010+Design%2fLasmer%2findex.aspx). I want it to go to the client folder (Lasmer in this case) once the user has been authenticated. Shouldn't it send me to the folder's default page once it knows the user is authenticated? Do I have a problem in the way my web.config is wired up, and do I need anything in the client folder's web.config?Here is the code for the web.config:

Here is the code for the handler:

Protecting Content E.g Images?

Apr 14, 2010

I have images displayed in a website behind a username and password that is accessed by our customers. I have put in some simple measures to prevent users from copying these images. E.g placing an opaque image over the core image so that when users right click and save the image all they get is the opaque image.

I have concerns that customers could easily pass on their user credentials to competitors who can then freely view all the images.

VS 2013 / PDF Protecting / Stamping And Locking?

Jun 9, 2015

I have an ASPNET Application (C#) that runs on my company intranet. This application allows the users to attach PDF files against records.

I am trying to get that PDF uploaded in such a way that whenever the user initially uploads (the uploaded PDF will always be unlocked PDF), the user name would be stamped on the PDF file and the files is locked by my application so that the user cannot change the PDF again, even when having a PDF Writer. Whenever required the application should allow the user to unlock the PDF and then allow the user to edit the PDF.

Protecting The (location) Element On Web Config?

Oct 26, 2011

Now since i'm securing the site i've noticed that the location element does not get much attention.The only thing i have found is that you can use <location path="" allowOverride="false"> on machine.config .I'm not sure how this goes but if you need to use this one every page then i will have multiple problems.First if i have a page with the same name on another website there is trouble and also if i need to update pages again problem.What i'm not sure of is if the location element on machine.config i just used once and then magically every site you have will throw an exception if a hacker changes you web.config.I have doubts and it's confusing and if i play with the server web.config,well i don't wanna mess with that.

So i also tried to encrypt the location element but i cannot find an example(can you encrypt it?).I can encrypt authorization and authentication but i will not go inside the location element.Just the standard authorization and authentication nodes.How can i secure the web.config location element so no hacker can change the allow,deny,etc.

C# - Protecting Variable Inside Of Markup : Hyperlink Navigation Property

Mar 2, 2011

I have an asp.net repeater control with a series of asp:hyperlink's

<asp:HyperLink runat="server" ID="name" NavigationUrl="~/Pages/display.aspx?fileid={0}&user={1}" />

and then on the OnItemDataBound method:

fullname.NavigationUrl=string.Format(name.NavigationUrl, user.fileid, user.userid);

So that gives me a series of URLs in the repeater:

[URL]

OK, so with a simple proxy tool someone can replace either of the parameters with some OTHER number to get access to what they shouldn't see.

server-side validation and authentication aside, is there a better method other than passing parameters when trying to create a dynamic URL within a repeater?

Configuration :: Hiding And Protecting Static XML Files - Embedded Resource?

Nov 3, 2010

Does precompilation have any effect on XML files? i.e. can I obscure/protect xml files using precompilation? I assume that it has no effect as they aren't code.

If I use XML files as Embedded Resources, they appear in the DLL in a text editor as normal text. If the dll is edited and saved using a text editor, will it still work if it is unsigned?

Protecting Personally Identifiable Data In SQL Server 2008 Environment

Jan 18, 2011

I've read up on SQL Server 2008's encryption function, but I'm not convinced that's the route I want to go. My problem ultimately boils down to the fact that we're either using symmetric keys or assymetric keys encrypted by a symmetric key. Thus it seems like a SQL injection attack could lead to a data leak. I realize permissions should prevent that, permissions should also prevent the leaking in the first place.

It seems to me the better method would be to asymmetrically encrypt the data in the web application. Then store the private key offline and have a fat client that they can run the few times a year they need to access the restricted data so the data could be decrypted on the client. This way, if the server get compromised, we don't leak old data although depending on what they do we may leak future data. I think the big disadvantage is this would require re-writing the web application and creating a new fat application (to pull the restricted data). Due to the recent problem, I can probably get the time allocated, so now would be the proper time to make the recommendation.

Security :: Custom Access Denied Page For Role Based Security?

Oct 27, 2010

I have implemented role based security in my asp.net 2.0 vb.net application using windows authentication and the windowstokenroleprovider and limiting access to certain pages using the location tag to specific active directory groups.

The issue is that when a user tries to access a page they are not authorized to view it brings up a login prompt and when it does not pass it takes them to the default page that tells them they are not authorized to view the page. I am wondering if there is a way to throw up a custom page that tells them they are not athorized to view the page that I can incorporate into the site itself with the header and so forth? if this page could come up in lieu of the sign in box popping up as well.

Security :: SiteMap - Different Security Trimming For The Same Page?

Mar 3, 2011

I have a site map with a node and two inner nodes. The inner nodes have the same url but a different querystring parameter. I want the users with role "User" to see only the second of these links in their menu.

This is my siteMap:

[Code]....

This is the configuration of the web.config:

[Code]....

As a result, the users with role "User" can see only the second link (Search) which is fine, but they get an Access Denied when they navigate to it which is logic since they don't have access to that page, but it's not really fine for me.

Jan 11, 2011

I am using Visual Studio 2008 Express and created a login page using the ASP.net web site Adminstration tool security to generate users and passwords.

After login, a new page appears. I have a button to go back to the login page to allow a user to relogin. When I try loging in again as a different user or the same, I get an error saying the resource that I am looing for was not available.

I have a button on the page after login (one this one page will occur) and I am using on on click event to do the following:

FormsAuthentication.Initialize()
FormsAuthentication.SignOut()
Response.Redirect("~/Login.Aspx")

After clicking on this button, the Login page appears again. How can I release everyting to allow it to work like when I first open the application.

This is the error message I get:

Description:

The resource cannot be found.
