secure web server asp.net

I have a graphical user interface for my company product. I want to secure the data being sent back and forth between client and server.

Is SSL one of the options? if yes, Please can some1 tell me the steps on how to implement it in my application code.

Do i need to buy the certificate or can i make it.. which is the best choice?

Any help is appreciated. thanks..

I am logging in using FormsAuthenticationTicket as follows:

Session["userName"] = UserName.Text;
                    Session["password"] = Password.Text;
                    Session["domain"] = Domain.Text;
                    string role = "Administrators";

                    // Create the authentication ticket
                    FormsAuthenticationTicket authTicket = new FormsAuthenticationTicket(1,                          // version
                                                   UserName.Text,           // user name
                                                   DateTime.Now,               // creation
                                                   DateTime.Now.AddMinutes(60),// Expiration
                                                   false,                      // Persistent 
                                                   role);         // User data

                    // Now encrypt the ticket.
                    string encryptedTicket = FormsAuthentication.Encrypt(authTicket);
                    // Create a cookie and add the encrypted ticket to the
                    // cookie as data.
                    HttpCookie authCookie =
                                 new HttpCookie(FormsAuthentication.FormsCookieName,
                                                encryptedTicket);

                    // Add the cookie to the outgoing cookies collection.
                    Response.Cookies.Add(authCookie);

                    // Redirect the user to the originally requested page 
                    Response.Redirect(FormsAuthentication.GetRedirectUrl(UserName.Text, false));

I am not sure how secure this is?? any suggestions.

SSL is indeed a possibility. Have a look at: http://support.microsoft.com/kb/813829

You do possibly need to alter code though (see link above).

Is SSL one of the options?

It is the only sensible one

if yes, Please can some1 tell me the steps on how to implement it in my application code.

Assuming you are dealing with a browser (as opposed to your own client applications that then communicates with the server via HTTP). You don't go near your application code with SSL (other than making sure your URIs are https ones).

You just install an SSL cert on the server.

Do i need to buy the certificate or can i make it.. which is the best choice?

You can produce a self-signed cert, but this will generate scary warnings about trust in the user's browser. If the users are technically savvy or you have the resources to install the cert (and mark it as trusted) on all the clients before hand, this is fine. Otherwise you probably should buy one.

Using authentication in your .net code will not secure the communication "on the wire." SSL is THE option of securing web traffic between a browser and the web server. You will need to purchase a secure certificate and configure your web server (not your ASP.NET application) to use the certificate.
