Security :: Forms Authentication And Authorization?
Feb 16, 2010
I'm using Visual studio 2005 with C# on .NET framework 2.0.. I am implementing forms authentication in this project but the problem is when I'm on registration form ( outside login) and try to open any window on that form using java script (window. open) it redirects me to login page. How should i tackle this problem??
I'm using Forms authentication in ASP.NET MVC website and I store user account login name in AuthCookie like this: FormsAuthentication.SetAuthCookie(account.Login, false); I want to ask if there is a possibility that user on client side will somehow manage to change his login name in AuthCookie and thus he will be for example impersonated as someone with higher privileges and authorized to do more actions than he is normally supposed to have. Also is it better to save in this cookie user account login name or user account ID number?
What is the authentication mode available in ASP.NET? How do you set authentication mode in the ASP.NET application? How do you provide secured communication in ASP.NET? List out the difference between windows authentication and form authentication. ?
I have an old website running fine in Classic ASP with large customer base registered onto the site. The current site allows users to have their own user name(unique) registered against an ID assigned to them. They can change the User name later as well provided it is still Unique in the database(Database is SQLServer2005).
The Problem: Now i want to move the website to .NET and want to use the .NET Membership. I know how to create the database structure in SQL Server through aspnet_regsql script but my problem is how should i import the existing username and passwords as the password stored in MembershipDB is Hashed (salt). Also i might want to allow admins to impersonate as users later.
I have a web application that requires two separate authentication and authorization.
In the root webconfig i configure the security for authenticating and authorizing public users
I also need authentication and authorization for the back end. That is the administrator who will manage the web application.
For this i have a subdirectory "admin" that will contain all the functionality for the back end. In the "admin" subdirectory i have a second web.config and i tried to add all the security for the administrator but it does not let me
Is it possible to have to separate authorization and authentication for a single web application. All the details will be save in microsoft's sql tables generate (for example aspnet... tables)
I've just started a small ASP.NET web application. In this project, I need to authenticate the users with Active Driectory. I managed to authenticate the users successfully with Active Directory. But with Authorization with Custom Role Provider, I'm so confused.You see, the user name and password are stored in AD. So, my approach is that after the LoggedIn event of the Login Control, I check if UserName is not yet stored in the Users table yet, then I will store the UserName there. Eventually, I have all the UserName of the AD users store in the Users table so I can assign Roles to the users.
Let's say I assigned UserA to RoleOne. After he logs in successfully, I do some query to look for his Roles.
Where do I keep the Role ticket? In the Cookie or in the session? How does the authorization of ASP.NET role provider work? I want to store the authentication ticket like ASP.NET role prover does too.
In my asp.net website in VS-2005 with SQL-Server 2005 as db, I need to implement role-based Authentication/Authorization.
I am familiar to the practises used in role-based authentication..as I have previously worked on projects that used this method. However, my project lead used to design the database. Now I have an existing website where authentication has been set to anonymous by setting 'allow users="?"' in the authentication tags in web.config.
If I use the createUserWizard control and use the Membership.creatUser(.....) method in code behind will the asp.net security tables, like users, roles, userinrole etc get created on its own?
I am trying to implement a simple role based authorization using forms authentication in ASP.net. It works perfectly fine in my local system but fails when I deploy in production (shared hosting). Whenever I try to log in, rather than taking me to the default page in specified directory it throws me back to the login page. I suspect that there is some issues with the configuration but not sure where the problem is. The code is provided below:
Web.config (Member directory):
Works fine in local machine but shared hosting is not taking the authenticated user to the pages inside the secured folders. What can be the issue?
I am using ASP.NET MVC 3 and am trying to do something that should be really straight forward...
My application uses Forms authentication and that is working perfectly for controllers/actions. For example if I decorate either a controller or an action with the attribute below only members of the administrators group can view them:
However I have a folder under the default Scripts folder called Admin. I only want members of the Administrators group to be able to access scripts within this directory so I created a new web.config in the directory with the following inside:
However no matter whether a user is a member of the Administrators group or not they receive a 302 Found message and are then redirected to the login page.
If I change the web.config to allow user="*" then it works. It also works if I add an allow users="Username" for a specific user I am testing with.
I am writing two ASP.NET apps. One is a web service that provides xml data and the other is a web client that will use the service to display and manipulate data. I would like for the web service to do the membership authentication and authorization. Is there any way to simply point the login controls in my client application to the web service instead of to a database. I assume I would have to provide the necesarry methods in my web service interface, which would then use the membership provider database I created and pass the results back through to the client.
Is this possible? I have seen many articles on security provisioin from a web service but none has really been what I am looking for. I was hoping that, since my service and my client are both written in ASP.NET, there might be some built functionality that would benefit me.

I've been through the sample application in Steven Sanderson's "Pro ASP.NET MVC2 Framework". I've learned a lot and am now trying my hand at some of the concepts.So, I'm trying to make the Forms Authentication and Authorization work using Ninject DI. I believe I have the concepts correct (maybe) however, I'm having troubles with creating the correct interface for the FormsAuthentication ASP.NET class. Since the code is in ASP.NET and not MVC I do not have access to the class in order to build the interface.I want to use the built in Forms classes to take advantage of the authorization filters, etc.So, my question is this:1. Are there any examples out there that encapsulate Forms Authentication/Authorization?2. Is this a fools errand?. Are there better solutions than the built-in Forms solutions that still offer the authorization filters, etc?
Our team has recently implemented a role permission based authorization so that we can have granular control. This is similar to what Rockford Lhotka suggests herehttp://www.lhotka.net/weblog/PermissionbasedAuthorizationVsRolebasedAuthorization.aspx I have also read about the Claims based authorization which to me looks very similar to what we have. Can some one put in simple terms what the advantages of claims based authorization are.
Iam using forms authentication in asp.net Application,i want to make pages accessible depending upon roles defined in database. for eg there are three rolesdefined in database salary admin, manager, Clerk. i want a page salary.aspx can be accessed only by salary admin and not any other roles.
I have the usual requirement of implementing Authentication and Authorization. I used to implement it using custom code where I have Users, Roles, Role_Pages, User_Pages, and User_Roles. So this way we can give a certain user roles (that group multiple pages) and/or directly define access to certain pages. All that with the ability to specify fine grained permissions like the ability to Add/Edit/Delete records in those pages.
My question: How easy is it to implement this using Forms Authentication and what advantage does that give over implementing a custom solution. I am also concerned with knowing if there would be any advantage when it comes to securing from session hijacking and against spoofing where an attacker could replay requests and impersonate legit users. Would Forms Authentication have any advantage there, or is it only SSL that can secure against that (which makes both approaches equal in that regard).
I am new in Asp.net MVC but i really like it. I always prefer flexible authentication systems, on the other hand security is very important issue too. So i looked for some sipmle way to store current loged "user id/user name" in server side. I think that "HttpRuntime.Cache" can be a answer. So i write simple test project Of course this code is is not complete.
I am building an intranet website. And I am still unsure of how to implement the security of the website. I am using ASP.NET MVC 3.
Anyone in the company can access the website. It is a recognition system where you can nominate an employee for an award. Currently I am not using any type of authentication. I have a roles table that contains roles and an association table that specifies which user contain what roles, these roles are mainly administrator-type roles. If a user does belong in these roles then he/she can still access various parts of the website.
Would I need to use the built-in membership for this? Or would I need to create a custom membership for this? We don't use a login page. If the user does not have roles to access a view then he/she is redirected to another page.
We use IIS to do our authentication. Is this the same as Windows authentication? I have the roles table used for authorisation.
I've just run into one of the problems of using the integrated dev server (Cassini) in VS and would like to see if there are any solutions.We're using asp.net authentication to secure the site. However, Cassini runs in integrated pipeline mode, meaning that requests for all files go through the asp.net isapi. The result of this is that it's securing files that would otherwise not be secured in a production environment (.htm .js .css etc..).
Now I understand that we can run the project on a local IIS instance, but we would like to avoid this if possible. But, because of the problem above, this is looking like the only solution.Does anybody have any ideas about how to get Cassini working with authentication that can be easily moved to a production environment when ready. (I'd also like to avoid having a different development web.config that specifically allows access to these files).
