I have a website running on iis 5.1 with asp.net 2.0. Where in the windows registry can I change the requirtements for some the security features? For example, I do not want to enforce strong passwords and I do not want to use the secret question and answer features.

View 1 RepliesMy issue today is that i have a MySQL Database and am using the security framework provided by the ASP.NET Membership and Role Providers...I override the default methods with my own MySQL.
Now the issue comes in when i someone would like to have their password reset. My application is running entirely on an Intranet so i cannot have their passwords emailed to them. Is there a way i can have this information displayed in any way so that the user can use it to Log Reset, Create Accounts or Recover their lost passwords on an intranet without the administrators intervention?
Recently i had an approach as follows. In my web.config<system.net><mailSettings><smtp deliveryMethod="pickupDirectoryLocation" and my location was a folder on C drive as c:/SavedPasswords. Now i understand this was such a big security threat and thats why i am looking for a better option.
I would have that folder created using my System.IO and then the Mail is dropped into that folder. Then after the process is successful, i tell the user to check into that location and Read its content.
Then there is a global variable that is set to true...meaning that the folder at c:/ has been created. then there is a Method in a certain class that once it sees this variable True, it reads the readers c:/ and deletes that folder "save" if it exists;
I have a small database, with a very small number of users. The passwords were stored as clear as the database was so small and held no sensitive data. The database is now to be expanded and passwords are required to be encrypted. I can change the Password Format in the web.config, but is there a way to change the existing passwords from clear to encrypted?

How to enforce logon hours validation
View 10 Repliescurrently im trying to implement a quiz system on my website in which system will auto mark student's ans. if the student's ans is wrong, system will prompt an incorrect answer, highlight the errors and count the number of errors.
Im using asp.net C#.
I simply want to know how to manually check if the value a user has provided for the answer to their security question matches their current answer on record. I want to use the build in support of the membership and membershipuser objects.
I see that via the passwordrecovery control that the actual answer can be returned. However I am currently not using this control and it would take a good bit to integrate it as it does not meet our user's requirements.
In a worst case scenario, getting the actual answer (like the passwordrecovery control does) and manually checking it in our application would be acceptable.
A best case scenario is some sort of API where I can pass in the user name and the answer to their security question that was provided and simply get an indication of whether answer was correct or not.
I'm using asp.net's built-in membership provider with security question-and-answer enabled for password recovery against a SQL Server 2005 db. For some users, this works fine and they're able to receive their passwords. For others, and it's not clear what separates the two groups, the security answer is never properly processed. It doesn't matter if the answer is correct or incorrect, the page merely reloads without confirming or denying the request.As for events, VerifyingAnswer is being triggered, but not AnswerLookupError (if answer is incorrect) or SendingMail (if answer is correct). I ran a SQL trace during one instance, and the aspnet_Membership_GetUserByName stored procedure is being called, but nothing else gets called after. I would expect that aspnet_Membership_GetPassword would be called, which passes the security answer as a parameter, but it isn't.

There are three ways of resetting and changing passwords explained at
Microsoft ASP.NET site[URL]
Step 1: Helping Users Recover Lost Passwords
Step 2: Changing Passwords
Step 3: Allowing Administrators to Change Users' Passwords
In step 1 and step 2 end user passwords are sent by an email.
In Step 3: functionality is explained where administror changing the password and sending through email msg. refer "I encourage those readers interested in this functionality to become more familiar with the code and try extending the functionality to include sending an email to the user whose password was changed.

Is Sending passwords by emial secure enough or best security password at all? I have implemented functionality where Admin sending passwords to end users by changing once in 3 months. End users expressed their views that sending passwords by email is not secure. When there is security threat in sending passwords by email, Microsoft security experts should not emailing passwords in above mentioned article, which is still up to date.
I am making application in asp.net and I wanted to implement security features in my application I want help from you experts with good logic on implementing security Field Level, Button Level and different DIV section level security. Where I wanted like read only, addition, edit and delete and also I can make Groups and then assign user in that so that group security I can give. Customize security for some users.I am ready to use some DLL or Active X which give me above.
Before I was using database for security logic where in I was putting some codes in comma format and was looking that for specific control on form load but it have disadvantage that when some user have access to database that can alter make problem.
I have these settings.. in my webconfig..

So i dont need to use Q and A for password retrevial ( I use email password recovery), but I would like to use Q and A as and Admin, just as that higher level of secuirty.How can I turn off the encryption of the answer of the Q and A, or decrypt it in a report or something ???

How should i do it?
Mine is an asp.net website on c#.
I have to perform an action and want to authorize and authenticate before performing that action because it is very crititcal.
I can provide normal user and password. but besides that how can i ensure that its secure ??
Any more levels of security features i can provide.
how can i implement RSA ?? in such a scenario?
So as the title suggested, I'm currently trying to compare the hashed answer in my database against the answer typed in the textfield by the user in the form.
I thought of hashing the answer in the textfield typed by the user first, and after that compare this newly hashed answer to the one in the database (which is already hashed). But when I typed in the SAME answer (before hashing) and hashed it to get the hashed value, by right the 2 hashes (in web form and database) should match? Somehow, it didn't. And I can't seem to get security answer right anymore (even though I typed the SAME security answer).

I'm dealing with a scenario where a legitimate user doesn't have a clue about his password, secret question or the answer. So, I was trying to create an admin tool that would help me in situations like these where the admin should be able to type in username and reset the password without having to know/enter answer to secret question. I understand that I need to make some changes to the web.config for this to work. I thought I made all the changes but my ResetPassword() requests are still not working.
Here's my web.config settings for the provider.

I have an asp.net page where I have used FormsAuthentication.HashPasswordForStoringInConfigFile. Encrypted password is saved in database. I have created a forgotPassword page. Where I need to send user his password. How can I decrypt it and send it to user. if SHA1 can not be decryoted what other option should I use to encrypt the passwords?
View 5 RepliesI want the login password to not be sent in plaintext (due to the risk of hijacking). I know that this can be achieved in principle using MD5 or the like, but is there a common implementation for use with Asp.Net? Of course, it's crucial that the resulting hash (?) isn't easy to decrypt. When I read various posts on this matter, some people say it's just to do a reverse on the encrypted string, so that in effect, this is totally useless.

View 5 RepliesI need to store passwords provided by the user. Yes, passwords. I could not use Hashes because I need to supply the password to another external service for authentication, and therefore I need to have the password.
What is the best and most secure way to store the passwords? As the external data provides private data it is of course very important that the password in my MS SQL DB is stored as safe as possible.
