Introduction to Authentication Journeys in ForgeRock AM

Authentication journeys in ForgeRock AM are visual representations of the steps a user goes through to authenticate themselves. These journeys are defined using authentication trees, which are powerful and flexible tools for managing user interactions during the login process. In this post, we’ll dive into creating and optimizing these journeys to ensure they are both user-friendly and secure.

Setting Up Your Environment

Before diving into authentication journeys, ensure your ForgeRock AM environment is up and running. You need to have access to the ForgeRock AM admin console and be familiar with basic configuration tasks. For this example, I’ll assume you’re working with ForgeRock AM 7.2.

Creating a Basic Authentication Tree

Let’s start by creating a simple authentication tree that requires a username and password. This will serve as the foundation for more complex journeys.

Step 1: Access the Admin Console

Navigate to your ForgeRock AM admin console and log in with administrative credentials.

Step 2: Create a New Authentication Tree

  1. Go to Realms > [Your Realm] > Authentication > Trees.
  2. Click New Tree.
  3. Enter a name for your tree, e.g., BasicAuthTree.
  4. Select Username Password Node as the root node.
  5. Configure the node by setting the Service property to frRest.
  6. Save the tree.

Step 3: Test the Authentication Tree

  1. Go to Realms > [Your Realm] > Applications > Agents > Web.
  2. Create a new web agent and configure it to use your newly created tree.
  3. Deploy the agent to your web application.
  4. Access your web application and attempt to log in using valid credentials.

If everything is set up correctly, you should be able to log in successfully.

Enhancing the Journey with Multi-Factor Authentication (MFA)

Multi-factor authentication adds an extra layer of security by requiring users to provide two or more verification factors. Let’s enhance our basic journey to include MFA using SMS.

Step 1: Add an SMS Node

  1. Open your authentication tree (BasicAuthTree) in the admin console.
  2. Add a new node after the Username Password Node.
  3. Select SMS Node.
  4. Configure the node by setting the Phone Attribute to the attribute where user phone numbers are stored, e.g., telephoneNumber.
  5. Save the tree.

Step 2: Configure SMS Provider

ForgeRock AM supports various SMS providers. For this example, let’s use Twilio.

  1. Go to Realms > [Your Realm] > Services > SMS Service.
  2. Add a new SMS provider and configure it with your Twilio credentials.
  3. Test the SMS configuration by sending a test message.

Step 3: Test MFA

  1. Access your web application and log in using valid credentials.
  2. After entering the username and password, you should receive an SMS with a one-time passcode (OTP).
  3. Enter the OTP to complete the login process.

Common Pitfalls When Configuring Authentication Trees

Configuring authentication trees can be tricky, especially when dealing with multiple factors and conditions. Here are some common pitfalls to avoid.

Incorrect Configuration of Nodes

One of the most common issues is incorrect configuration of nodes. Always double-check properties such as Service, Phone Attribute, and any other required fields.

Example of Incorrect Configuration:

{
  "nodeType": "UsernamePasswordNode",
  "configuration": {
    "service": "frInvalidService" // Incorrect service name
  }
}

Correct Configuration:

{
  "nodeType": "UsernamePasswordNode",
  "configuration": {
    "service": "frRest" // Correct service name
  }
}

Misconfigured Conditions

Conditions in authentication trees determine the flow based on certain criteria. Misconfigured conditions can lead to unexpected behavior.

Example of Incorrect Condition:

{
  "condition": {
    "type": "script",
    "value": "return false;" // Always returns false
  }
}

Correct Condition:

{
  "condition": {
    "type": "script",
    "value": "return true;" // Returns true for testing purposes
  }
}

Missing Error Handling

Error handling is crucial for providing meaningful feedback to users. Ensure that your authentication tree includes error handling nodes to manage exceptions gracefully.

Example of Missing Error Handling:

{
  "nodeType": "UsernamePasswordNode",
  "configuration": {
    "service": "frRest"
  }
  // No error handling node
}

Correct Configuration with Error Handling:

{
  "nodeType": "UsernamePasswordNode",
  "configuration": {
    "service": "frRest"
  },
  "onException": {
    "nodeType": "ScriptedDecisionNode",
    "configuration": {
      "script": "return Action.send(500, 'Internal Server Error');"
    }
  }
}

Securing Authentication Journeys Against Phishing Attacks

🚨 Security Warning: ## Securing Authentication Journeys Against Phishing Attacks

Phishing attacks remain a significant threat to authentication systems. Here are some strategies to secure your authentication journeys.

Use Strong Password Policies

Enforce strong password policies to reduce the risk of weak passwords being compromised.

  1. Go to Realms > [Your Realm] > Services > Password Policy.
  2. Configure policies such as minimum length, complexity requirements, and password history.

Implement Account Lockout Mechanisms

Account lockout mechanisms prevent brute-force attacks by locking accounts after a certain number of failed login attempts.

  1. Go to Realms > [Your Realm] > Services > Account Lockout Policy.
  2. Configure settings such as maximum failed attempts and lockout duration.

Use Secure Communication Protocols

Ensure that all communication between the client and server uses secure protocols like HTTPS.

  1. Configure your web application to enforce HTTPS.
  2. Use SSL/TLS certificates to secure data in transit.

Monitor and Log Authentication Attempts

Regularly monitor and log authentication attempts to detect suspicious activity.

  1. Enable logging in ForgeRock AM.
  2. Set up alerts for unusual patterns, such as multiple failed login attempts from different IP addresses.

Advanced Features: Conditional Logic and Custom Scripts

ForgeRock AM provides advanced features such as conditional logic and custom scripts to tailor authentication journeys to specific requirements.

Using Conditional Logic

Conditional logic allows you to create dynamic authentication journeys based on user attributes or other conditions.

Example: Conditional Logic for MFA

{
  "condition": {
    "type": "script",
    "value": "return user.getAttribute('role') === 'admin';"
  },
  "true": {
    "nodeType": "SMSNode",
    "configuration": {
      "phoneAttribute": "telephoneNumber"
    }
  },
  "false": {
    "nodeType": "SuccessNode"
  }
}

Writing Custom Scripts

Custom scripts provide the flexibility to implement complex logic that may not be covered by built-in nodes.

Example: Custom Script for User Verification

// Custom script to verify user attributes
function verifyUser(user) {
  if (user.getAttribute('status') !== 'active') {
    return false;
  }
  if (user.getAttribute('lastLogin') < new Date().getTime() - 30 * 24 * 60 * 60 * 1000) { // 30 days ago
    return false;
  }
  return true;
}

if (!verifyUser(user)) {
  return Action.send(403, 'Access Denied');
} else {
  return Action.goToNext();
}

Best Practices for Managing Authentication Journeys

Here are some best practices to ensure your authentication journeys are efficient and secure.

Keep Authentication Trees Simple

Complex authentication trees can lead to maintenance challenges. Keep your trees simple and modular.

Regularly Update Authentication Trees

Authentication requirements change over time. Regularly review and update your authentication trees to reflect current security standards.

Test Thoroughly

Thoroughly test your authentication journeys in a staging environment before deploying them to production.

Document Your Configuration

Document your authentication tree configurations and any custom scripts used. This documentation will be invaluable for troubleshooting and future maintenance.
