Security :: Use Login Control And In 3-tier Architecture?

Jan 19, 2010

I am creating the web site (storing the employee Info) in this I am using 3-tire architecture ASP 2.0. But I am confusing that how to use the login control in this and how it wills validate the username and password with table store in my database. In this I have two table (fk_tbluser and tblemployee). In fk_tbluser all named user will store (username and password) and in the tblemployee(employee no and password) table I am storing the password of employee login.

When Named user will login in the portal it has to pass the Admin in the username and password which stored in the fk_tbluser table.

E.G: username : admin
password : admin password which stored in the fk_tbluser table.

When employee will login in the portal it has to pass the employeeno as username and password which stored in the tblemployee table.

E.G: username: 000001
password : employee(000001) password which stored in the tblemployee

Security :: PrincipalPermission With N-Tier Application?

Jul 6, 2006

I am writing a new application which has been seperated into layers (UI, Logic, Data Access). Right now all the layers are self contained in my application...which may be broken out at a later date. Also these layers have a seperate namespace as well such as BusinessLogicLayer, DataAccessLayer, etc... On my methods within the Business Logic and Data Access, I am wanting to use the Principal Permission Attribute.

For example I have a class called State & StateCollection which holds U.S. State information such as name and FIPS code. One method called GetStates() demands that a user have a certain role.

''' <summary>
''' Gets all states and their associated information
''' </summary>
''' <returns>A collection of states</returns>
<PrincipalPermission(SecurityAction.Demand, Role:="modifyPropects")> _
Public Shared Function GetStates() As StateCollection
Dim dbConn As DataAccessLayer.DataAccessBase = DataAccessLayer.DataAccessBaseHelper.GetDataAccessLayer
Dim dt As Data.DataTable = dbConn.SelectStates()
Dim stCol As New StateCollection


When I try to call this method from the UI the principal permission attribute specified in the business logic layer is ignored, and the states list is displayed. However if I do this instead:

If HttpContext.Current.User.IsInRole("modifyPropects") and throw an exception it works. Thus, I know roles are getting assigned as this type of check does function.

Architecture :: Developing A Simple System Notification Mechanism

Nov 22, 2010

I'm looking for a simple way of developing "System Notification" in an ASP.NET website, which will consist of two parts: Part 1 - The administrator with go to a special page and enter 3 elements for the notification:

Notification Text (e.g. "System will be down for maintenance next Sunday 11/26/2010 from 1:00 AM to 1:30 AM Pacific Time) Starting date/time when the notification should be displayed (e.g. 11/23/2010 6:00 AM) Ending date/time when the notification should be displayed (e.g. 11/26/2010 1:30 AM) Part 2 - Once the user logs into the website within the above timeframe, the system notification message will appear on the home page. What would be a good architectural location for this?

- A table?
- An html page?
- Part of web.config file?
- A new notification.config file?
- Where else?

Security :: Sharing Login Between Three Websites (application)?

Jul 5, 2010

I have a scenario with three applications:

1) Portal: where user executes login

2) Site1: after login at "Portal" user is able to use Site1

3) Site2: after login at "Portal" user is able to use Site2

I just need to execute a validation in Site1 and Site2, to validate if they (users) did login at Portal1.

Something like (in site1 main page page_load).

if (notFromPortal)
//redirect to Denied.apx

How can I do this in a simple way? With cookies? Does somebody have a url with sample?

My security requirements are almost zero. I just wanna prevent that user put a url from Site2 in browser and see a Site2 page.

Security :: Application Using AD Form Authentication - Login Not Responding

Aug 23, 2010

I've encountered a problem with intranet ASP.NET Application using AD Form Authentcation. The login and authorization is built using this KB It works fine on DEV but not in UAT and PROD.

Basically, the problem is:1. In DEV, users see login page and they enter domain user name and password and login process happens with no issue.

2. But in PROD and UAT, the same application when the users see the login page (first time) and they submit the login form no response. The login button does nothing. The user closes the browser and come back to login page and it works second time. Strange, this doesn't happen in DEV.

3. Further, on DEV by changing the LDAP path to PROD or UAT, the users can still login the first time. It's only the PROd and UAT that seems to be a problem. Not sure whether it's IIS setting or domain policy or something else.....

Not sure what's causing this issue. The only difference that I can see between DEV and UAT/PROD is:

1. DEV has no load balance but UAT and PROD has.

2. In DEV application is installed under Default Website and on PROD/UAT it's under new website.

The IIS settings has been setup as per given KB. I

Security :: Structuring An Application That Will Feature Login Page?

Jul 23, 2010

I have a site I am working on, that will have a home page with a login control. I would expect that after logging in, access is permitted to only certain areas of the website. I would imagine that the properties set by the login control will determine which pages can be viewed. Does this make sense? I know that many other websites have this type of structure, just not sure how it is organized.

Security :: Login Form Rejecting Valid Login With Forms Based Security And Membership Service

Jan 21, 2010

I've set up a system with forms based authentication and using the asp:Login control. When I put in an invalid password I get the approriate invalid password message. However when I put in a valid password, it does nothing...just returns to the login page again. I'm triple checked the login info. There is no error message, and the invalid attempts counter doesn't increment. When I put a break point in the Login_LoggedIn event of the Login form, it hits it, but User.Identity.IsAuthenticated is false. I'm not 100% sure it should be true at this point, as I'm pretty new to .NET but it seems kind of odd.

My user database is stored in a sqlserver 2005 db that already existed. I've added a new connection for it.In the authorization I have

Recommended Tier Framework For Web Application?

trying to switch to better coding practises, I am totally confused about which path to choose. For the past year I was just coding through classic asp coding methodology. Now I know about things as

3 tier custom 3 tier with Strongly typed data sets N tier applications Custom entity objects and so on

Can someone recommend me an approach for designing web applications from these? Some book or tutorial reference with simple CRUD application that would help me. I am currently stuck with strongly typed data sets as I cant find CRUD tutorials with that approach. I would like to just choose the right approach and build on it.

Which Of The Two Design Patterns Should I Implement In A 3-tier .Net Application

Sep 22, 2010

I'm trying to decide which of the two factory patterns I should use in my Asp.Net applications:

1 : All DAL providers derive from same abstract base class DepartmentsProvider, which defines public interface of the class ( all the necessary CRUD methods for which derived classes (providers ) provide a concrete implementation ). BLL layer instantiates correct provider by calling DepartmentsProvider.Instance:

public abstract class DepartmentsProvider
static private DepartmentsProvider _instance = null;
/// <summary>[code]....

In first case we implement new provider by deriving from DepartmentsProvider class, while in second case new provider is implemented by deriving from DBProviderFactory. What are pros and cons of each implementation?

DataSource Controls :: Should The SqlDataAdapter Be Used With An N-tier Application

Dec 3, 2009

I have an app that has logical layers. These are typical Business Object , Business Logic, and Data Access Layers done with C#. I also have SqlDataAdapters for my Grid View and Details Views. This makes me wonder if I am truly using my layers the way they should be used. The SqlDataAdapters specify the stored procedures to use for the update, select and delete commands in the aspx file.

Would the SqlDataAdapters inherently by pass the logical layers? Are the logical layers do any thing with the SQLDataAdapter in place? Should I use the ObjectDataSource when working with Logical Layers?

Web Config - Where Should Connection Strings Be Stored In A N-tier Application

Sep 29, 2010

I have an ASP.NET project which is pretty n-tier, by namespace, but I need to separate into three projects: Data Layer, Middle Tier and Front End.

I am doing this because...

A) It seems the right thing to do, and

B) I am having all sorts of problems running unit tests for ASP.NET hosted assemblies.

Anyway, my question is, where do you keep your config info?

Right now, for example, my middle tier classes (which uses Linq to SQL) automatically pull their connection string information from the web.config when instantiating a new data context.

If my data layer is in another project can/should it be using the web.config for configuration info?

If so, how will a unit test, (typically in a separate assembly) provide soch configuration info?
