Security :: Create A .NET Application Backdoor Entry?
May 12, 2010
I am wanting to from now on create a backdoor entry for every web application I build so that if need be I can shut it down.I had a nasty recent experience of a client not paying the bill, however the application was on his server, so when I used my backdoor access to alter a hidden record in one of my database tables to stop it from running, they had full control of the server and were able to look through ther SQL log and see what queries had been run at that time and then alter the record and prevent access to the table...
The only way I can think of that will be full-proof no matter where application is (providing there is web access), is to have ONE webservice running on my server with all apps listed, with a secure interface and the ability for me to turn off any application. Then every day, once a day, each of my client's applications (no matter which server they are on) communicates with this web service to see if it is allowed to run by referencing a GUID. This once a day check would be compiled into the main app DLL.

I'm working on logging for all the updates in my web application. I.e, When some one is logged into application or some one changed any thing application, I'm logging everything in log table. But, I just want to know whether I can create log entry when I click on Logoff and I'm using Login Membership control.

I have a web application. This application needs to perform a search on folders located on 2 different machines. I can use impersonation for this. But -
a. I don't want to use network service account
b. I want to impersonate just the search part of the code.
c. Specifying encrypted user name / password in web.config is one option. But this would be the last option.
Can I use a custom service account for the application pool for this? If yes, then how to impersonate a specific part of code using this?

Let's say I'm currently authenticated in an application (namely: applicationA) and I click a link that will take me to another application (namely: applicationB). Is it correct that in order to bypass authentication of applicationB, I'll just create a ticket for that application telling the web server that I'm already authenticated?

I have an application which is installed on local pc and is using SQL db. It is a client management system where I want to add capability to register new clients and give them access to my web site which is sharing the same SQL database with local application.
At the moment clients can register on the web site and I have ASP.NET authorisation system set up with aspnetdb_user, aspnetdb_membership and etc tables. But sometimes it happens that I need to register clients on my local application on PC and ideally would like that registration to create online account for the client as well. Then I want to be able to send him user id and password by email and let him know that he has been registered in my database and online account is ready for him as well.
Basically I want to have full synchronization between asp.net membership service and local application through SQL db. As I said both online and local apps are shareing the same SQL database. what would be the best practice to implement it.

Suppose that you have a big Data Entry Web Application Like Microsoft CRM, what is the strategies and technologies that you follow to build a website like it?
I don't want to use any Dynamic Web Page Generation software, because it have a lot of limitations..
Also I don't want to design every page and repeat everything

While converting a desktop application to a web app, I've run across my ignorance when attempting to implement a multi-column data entry form using CSS. I'm resolved to avoid using tables for this type of thing, and while I found a good reference to laying out a data entry form, I can find nothing that applies to multiple-column layouts like this one:

I've been required to create an entry form to capture details relating to a travel booking. A user should be able to make a booking entering details related to the booking specifically the details of the persons that would be making the trip. This would involve a sort of parent-children relationship between the booking and the persons.
This would be relatively easy for me to achieve using web forms but then how can I easily achieve this is MVC using a single view? Do I have to create a sort of multistep form?

I already have 2 web applications running. both of them are using membership and accessing the same database but their application names are different. so basically in my aspnet_Users table, i have users with different applicationIDs and in my aspnet_Applications table I have 2 records in there. so i have 2 separate login locations
..app1login.aspx
..app2login.aspx
What my the business wants is to only have a single point of entry. so they want something like this
..applogin.aspx
and by verifying the username and password pair, my code should be able to route to the appropriate app and bypass its login form. (don't be concerned about the duplicate username between applications, it's been taken cared of)
so I'd like to solicit suggestions from you how should I implement this without modifying my existing setup? and where should I place this login web form in my website? this is the current site structure:
www.site.com/app1
www.site.com/app2

We are using membership provider for LDAP authentication. It is working as it should.
But what all configuration settings I have to do so that
all the future requests to this application run under the security context of the Logged in user account not through the some default user set in IIS.
We need to have this working because all the permissions on the database are based on the logged in user.
We are using form authentication for LDAP authentication. And having impersonation = true in web.config.

My website security is configured with "Windows Integrated Security" only (anonymous is disabled).
I also want to set a specific account to run the w3wp.exe process using the
Application Pool Identity to a domain account.
Running directly from the server works without any problem but from remote computers I always get the authenticaion window then the 401.1 error (after 3 attempts).
It seems that its the combination of "Windows Integrated Security" along with the "Application Pool Identity" that causes the problem. When I disable one of the two it works properly.
My server is Windows Server 2003 R2, running IIS 6.0.

Here is 2 web applications: 1 is asp.net, another is J2EE base webapplication.Both them are using same AD ( e.g. DomainTest ) as authentication source.Question here:1. User log in the asp.net application ( form based log in DomainTest, not IE prompt authencation dialog ), on the left navigation ( link to J2EE web application), just click this link, SSO to J2EE application.I think should transfer identity token from asp.net to J2EE, but don't know how, and for JSP, how to modify it to use token tranferd from asp.net ?

I have a C# 4.0 WinForm application that creates new Membership users using Membership.CreateUser(). I've created 1,000+ users. I run into problems when I access those same users from my Web application specifically MembershipUser.GetPassword(). I'm able to get the user in the Web app but when I try to get the password using MembershipUser.GetPassword() I get the "Unable to Validate data" error everytime. If I use the MembershipUser.GetPassword() method in the WinForm application it works fine. I'm using the same MachineKey in both applications.
WinForm App.config:
[Code]....
WebApp Web.config:

Error:
