You can implement security in the following ways.

Using the Dreamweaver Login Wizard

ColdFusion installs a Login Wizard command in the Dreamweaver Commands menu that generates a skeleton set of pages for managing user authentication and authorization.
The wizard asks you to select how to authenticate the login information. Select one of the following options:

  • Simple Specify a single user ID and password in the wizard. All users must enter this information to log in. Use this option for testing, or use the generated files as a template where you can replace the authentication code with more complex code. For example, to verify the ID and password against a database.
  • NT domain Specify an NT domain in the wizard, and the wizard generates code that queries the domain.
  • LDAP Specify the LDAP server and port, the user name and password required to access the login data, and the distinguished name to use to start the search for the user name. The wizard generates the code to query the LDAP server with the user ID and password.
    The wizard asks you to select one of the following options for displaying the request for login information:
  • Browser Dialog Box
  • ColdFusion Login Form

Structure code generated by the Login Wizard

The wizard generates or modifies the following files in the directory or site that you specify:

  • Application. cfc  If this file does not exist, the wizard creates it with a single  onRequestStart  method; it does not specify an application name or any other methods. If the file exists, but does not have an  onRequestStart  method, it adds the method. If Application.cfc and the  onRequestStart  method exist, the wizard inserts the required code at the beginning of the method. The resulting  onRequestStart  method has a  cfincludetag that specifies mm_wizard_application_include.cfm; it also has a simple form with a logout button, which appears at the top of each page in the application.

Note:

If the wizard creates the Application.cfc file, change the file to specify the application name. For more information on Application.cfc, see Designing and Optimizing a ColdFusion Application.

  • mm_wizard_application_include. cfm  The Login Wizard uses the information specified in the wizard fields to set several CFC method arguments. It then uses them to invoke the performlogin method of the master login CFC, mm_wizard.authenticate.
  • mm_wizard_authenticate. cfc This CFC contains all of the user authentication and login logic. The CFC consists of the following methods:
    • The ntauth , ldapauth , and simpleauth authentication methods check the user's name and ID against the valid login information, and return information about whether the user is authenticated. For the details of how they authenticate the user and the specific return values, see the methods.
    • The performLogin method is the master login method. It contains the  cflogin  tag, which displays the login form and calls the required authentication method. If the authentication method's return argument indicates a valid user, the method logs the user in.
    • The logout method logs out a user. If you specified Browser Dialog Box as the login page type, it also calls the closeBrowser method to close the browser window. This behavior is necessary because the browser continues to send the old login credentials after the user logs out, and the  cflogin  tag will automatically use them and log the user in again.
    • The closeBrowser method closes the browser window or tells the user to close the browser window to complete the logout , depending on the browser type.
  • mm_wizard_login. cfm  This file contains a ColdFusion login form. The wizard generates this file for all options, but does not use it if you specify Browser Dialog login.
  • index.cfm or mm_wizard_index. cfm  The wizard generates an index. cfm page if the directory does not have one; otherwise, creates an mm_wizard_index. cfm page. These pages let you test the generated login code before you implement your application, or without using any of your standard application pages. To test your login, open the index. cfm page in your browser.

Modifying the login code for your application

The Login Wizard creates a basic framework for authenticating a user. Customize this framework to meet the needs of your application. Typical security-related changes include the following:

  • Providing user-specific role information in the  cflogin  tag
  • Authenticating users against a database

Providing user-specific role information

The Login Wizard sets all users in a single role. In mm_wizard_authenticate.cfc, the performlogin method is hard-coded to set the role to "user." The authentication routines handle roles differently. (For the details, see the mm_wizard_authenticate.cfc code.) If your application uses roles for authorization, change the authentication method to get and return valid role information, and change the performlogin method to use the information in the roles attribute of its cfloginuser tag.

Authenticating users against a database

If you use a database to maintain user IDs and passwords, create your login framework by specifying simple authentication, and modify the code to use the database. The following instructions describe a simple way to change the code to use a database. They do not include all the cleanup work (particularly, removing the hard-coded user name and password) needed for a well-formatted application. 
Replace the following code:

<cfif sUserName eq uUserName AND sPassword eq uPassword> 
<cfset retargs.authenticated="YES"> 
<cfelse> 
<cfset retargs.authenticated="NO"> 
</cfif> 
<cfreturn retargs>

With code like the following:

<cfquery name="loginQuery" dataSource="#Application.DB#" > 
SELECT * 
FROM Users 
WHERE UserName = <cfqueryparam value="#uUserName#" CFSEQLType= 
'CF_SQL_VARCHAR'AND password = <cfqueryparam value="#uPassword#" 
CFSEQLType='CF_SQL_VARCHAR'> 
</cfquery> 

<cfif loginQuery.recordcount gt 0> 
<cfset retargs.authenticated="YES"> 
<cfset retargs.roles=loginQuery.roles> 
<cfelse> 
<cfset retargs.authenticated="NO"> 
</cfif> 
<cfreturn retargs>
Note:

For greater security, consider using a hashed password. Do not store the password directly in the database; instead, use the hash function to create a secure password fingerprint, and store it in the database. When the user provides a password, use the Hash function on the submitted string and compare it with the value in the database.

Web server based authentication user security example

The following example shows how to implement user security using web-server-based basic authentication and two roles,  user  and administrator. 
This example has two ColdFusion pages:

  1. The Application.cfc page logs the user into the ColdFusion security system and assigns the user to specific roles based on the user's ID.This page also includes the one-button form and logic for logging out a user, which appears at the top of each page.
  2. The securitytest.cfm page is a sample application page. It displays the logged-in user's roles.
    This simple example does not provide a user log-out interface. Test the security behavior by adding your own pages to the same directory as the Application.cfc page.

Example: Application.cfc

The Application.cfc page consists of the following:

<cfcomponent> 
<cfset This.name = "Orders"> 
<cffunction name="OnRequestStart"> 
<cfargument name = "request" required="true"/> 
<cflogin> 
<cfif IsDefined("cflogin")> 
<cfif cflogin.name eq "admin"> 
<cfset roles = "user,admin"> 
<cfelse> 
<cfset roles = "user"> 
</cfif> 
<cfloginuser name = "#cflogin.name#" password = "#cflogin.password#" 
roles = "#roles#" /> 
<cfelse> 
<!--- This should never happen. ---> 
<h4>Authentication data is missing.</h4> 
Try to reload the page or contact the site administrator. 
<cfabort> 
</cfif> 
</cflogin> 
</cffunction> 
</cfcomponent>

Reviewing the code

The Application.cfc  onRequestStart  method executes before the code in each ColdFusion page in an application. For more information on the Application.cfc page and when it is executed, see Designing and Optimizing a ColdFusion Application.The following table describes the CFML code in Application.cfc and its function:

Code

Description

<cfcomponent> 
<cfset This.name = "Orders"> 
<cffunction name="OnRequestStart"> 
<cfargument name = "request" required="true"/>

Identifies the application and starts the onRequestStart method that runs at the starts of each request. The login information on this page only applies to this application.

<cflogin> 
<cfif IsDefined("cflogin")> 
<cfif cflogin.name eq "admin"> 
<cfset roles = "user,admin"> 
<cfelse> 
<cfset roles = "user"> 
</cfif>

Executes if there is no logged-in user.Makes sure that the user is correctly logged in by the web server. (Otherwise, there would be no cflogin variable.)Sets a roles variable based on the user's ID. Assigns users named "admin" to the admin role. Assigns all other users to the users role.

<cfloginuser name = "#cflogin.name#" password = "#cflogin.password#" roles = "#roles#" />

Logs the user into the ColdFusion security system and specifies the user's password, name, and roles. Gets the password and name directly from the cflogin structure.

<cfelse> 
<!--- This should never happen. ---> 
<h4>Authentication data is missing.</h4> 
Try to reload the page or contact the site administrator. 
<cfabort>

This code should never run, but if the user somehow got to this page without logging in to the web server, this message would display and ColdFusion would stop processing the request.

</cfif> 
</cflogin> 
</cffunction> 
</cfcomponent>

Ends the if/else block.Ends the cflogin tag body.Ends the onRequestStart method.Ends the Application component.

Example: securitytest.cfm

The securitytest.cfm page shows how any application page uses ColdFusion user authorization features. The web server ensures the existence of an authenticated user, and the Application.cfc page ensures that the user is assigned to roles the page content appears. The securitytest.cfm page uses the IsUserInAnyRole and GetAuthUser functions to control the information that is displayed.
The securitytest.cfm page consists of the following:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> 
<html> 
<head> 
<title>Basic authentication security test page</title> 
</head> 

<body> 
<cfoutput> 
<h2>Welcome #GetAuthUser()#!</h2> 
</cfoutput> 

ALL Logged-in Users see this message.<br> 
<br> 
<cfscript> 
if (IsUserInRole("admin")) 
WriteOutput("Users in the admin role see this message.<br><br>"); 
if (IsUserInRole("user")) 
WriteOutput("Everyone in the user role sees this message.<br><br>"); 
</cfscript> 

</body> 
</html>

Reviewing the code

The following table describes the securitytest.cfm page CFML code and its function:

Code

Description

<cfoutput> 
<h2>Welcome #GetAuthUser()#!</h2> 
</cfoutput>

User is already logged in by Application.cfc. Displays a welcome message that includes the user's login ID.

ALL Logged-in Users see this message.<br> 
<br>

Displays this message in all cases. The page does not display until a user is logged in.

<cfscript> 
if (IsUserInRole("admin")) 
WriteOutput("Users in the admin role see this message.<br><br>"); 
if (IsUserInRole("user")) 
WriteOutput("Everyone in the user role sees this message.<br><br>"); 
</cfscript>

Tests whether the user belongs to each of the valid roles. If the user is in a role, displays a message with the role name.The user sees one message per role to which the user belongs.

Application-based user security example

The following example shows how to implement user security by authenticating users and then allowing users to see or use only the resources that they are authorized to access.
This example has three ColdFusion pages:

  • The Application.cfc page contains the authentication logic that checks whether a user is logged in, requests the login page if the user is not logged in, and authenticates the data from the login page. If the user is authenticated, it logs the user in.This page also includes the one-button form and logic for logging out a user, which appears at the top of each page.
  • The loginform.cfm page displays the login form. The code on this page could also be included in Application.cfc.
  • The securitytest.cfm page is a sample application page. It displays the logged-in user's roles.
    Test the security behavior by adding your own pages to the same directory as the Application.cfc page.
    The example gets user information from the LoginInfo table of the cfdocexamples database that is installed with ColdFusion. You can replace this database with any database containing UserID, Password, and Roles fields. The sample database contains the following data:

UserID

Password

Roles

BobZ

Ads10

Employee,Sales

JaniceF

Qwer12

Contractor,Documentation

RandalQ

ImMe

Employee,Human Resources,Manager

Because spaces are meaningful in roles strings, do not follow the comma separators in the Roles fields with spaces.

Example: Application.cfc

The Application.cfc page consists of the following:

<cfcomponent> 
<cfset This.name = "Orders"> 
<cfset This.Sessionmanagement="True"> 
<cfset This.loginstorage="session">

<form action="#CGI.script_name#?#CGI.query_string#" method="Post"> 
<table> 
<tr>

Reviewing the code

The following table describes the loginform.cfm page CFML code and its function:

Code

Description

<H2>Please Log In</H2> 
<cfoutput> 
<form action="#CGI.script_name#?#CGI.query_string#" method="Post"> 
<table> 
<tr> 
<td>user name:</td> 
<td><input type="text" name="j_username"></td>

<td>password:</td> 
<td><input type="password" name="j_password"></td> 
</tr> 
</table> 
<br> 
<input type="submit" value="Log In"> 
</form> 
</cfoutput>

Displays the login form. Constructs the form action attribute from CGI variables, with a ? character preceding the query string variable. This technique works because loginform.cfm is accessed by a cfinclude tag on Application.cfc, so the CGI variables are those for the originally requested page.'The form requests a user ID and password and posts the user's input to the page specified by the newurl variable.Uses the field names j_username and j_password. ColdFusion automatically puts form fields with these values in the cflogin.name and cflogin.password variables inside the cflogin tag.

Example: securitytest.cfm

The securitytest.cfm page shows how any application page can use ColdFusion user authorization features. Application.cfc ensures the existence of an authenticated user before the page content appears. The securitytest.cfm page uses the IsUserInAnyRole and GetAuthUser functions to control the information that is displayed.
The securitytest.cfm page consists of the following:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> 
<html>

Reviewing the code

The following table describes the securitytest.cfm page CFML code and its function:

Code

Description

<cfoutput> 
<h2>Welcome #GetAuthUser()#!</h2> 
</cfoutput>

Displays a welcome message that includes the user's login ID.

ALL Logged-in Users see this message.<br>

if (IsUserInRole("Employee")) 
WriteOutput("Employees see this message.<br><br>"); 
if (IsUserInRole("Contractor")) 
WriteOutput("Contractors see this message.<br><br>"); 
</cfscript>

Tests whether the user belongs to each of the valid roles. If the user is in a role, displays a message with the role name.Users see one message per role that they belong.

Using an LDAP directory for security information

LDAP directories are often used to store security information. The following example of a  cflogin  tag checks an LDAP directory to authenticate the user and retrieve the user's roles.
For more information on using LDAP directories with ColdFusion, see Managing LDAP Directories.

<!--- This filter will look for groups for containing the user's ID. ---> 
<cfset userfilter = "(&(objectClass=groupOfUniqueNames)(uniqueMember=#LDAP_username#))">

Starts the cflogin tag body. Sets several variables to the values used as attributes in the cfldap tag. Sets prefix and suffix values used to create a distinquished name (dn) for binding to the LDAP server.

Creates the user's bind  dn  by concatenating the prefix and suffix with  cflogin .name. This variable is used for authenticating the user to the LDAP server.Sets the filter used to search the directory and retrieve the user's group memberships. The group membership represents the user's roles within the organization.

<cftry> 
<cfldap action="QUERY" 
name="auth" 
attributes="cn" 
referral="yes"

scope="SUBTREE" 
server="#LDAP_server#" 
port="#LDAP_port#" 
filter="#userfilter#" 
username="#LDAP_username#" 
password="#cflogin.password#" 
>

In a cftry block, uses the user's concatenated dn to authenticate to the LDAP server and retrieve the common name (cn) attribute for groups to which the user is a member. If the authentication fails the LDAP server returns an error.

Note: The LDAP permissions must allow an authenticated user to read and search groups in order for the query to return results.

<cfcatch type="any"> 
<cfif FindNoCase("Invalid credentials", cfcatch.detail)> 
<cfoutput>

<script>alert("Unknown error for user: #cflogin.name# #cfcatch.detail#")</script> 
</cfoutput> 
<cfabort> 
</cfif> 
</cfcatch> 
</cftry>

Catches any exceptions. Tests to see if the error information includes the string "invalid credentials", which indicates that either the dn or password is invalid. If so, displays a dialog box with an error message indicating the problem. Otherwise, displays a general error message.If an error is caught, the cfabort tag ends processing of the request after displaying the error description.End of cfcatch and cftry blocks.

<cfloginuser name="#cflogin.name#" password="#cflogin.password#" 
roles="#valueList(auth.cn)#"> 
</cfif> 
</cfif> 
</cflogin>

If the authorization query returns a valid record, logs in the user. Uses the valueList function to create a comma-separated list of the users retrieved group memberships, and passes them in the cfloginuser roles attribute.Ends the initial isDefined("cflogin") cfif block .Ends the cflogin tag body
