Configure MFA Between Okta and the Firewall

Multi-factor authentication allows you to protect company assets by using multiple factors to verify the identity of users before allowing them to access network resources.
To enable multi-factor authentication (MFA) between the firewall and the Okta identity management service:

Configure Okta

Log in to the Okta Admin Portal to create your user accounts, define your Okta MFA policy, and obtain the token information required to configure MFA with Okta on the firewall.
  1. Create your Okta Admin user account.
    1. Submit your email address and name, then click
      Get Started
    2. Click the link in the confirmation email and use the included temporary password to log in to the Okta Admin Portal.
    3. Create a new password that includes at least 8 characters, one lowercase letter, one uppercase letter, a number, and does not include any part of your username.
    4. Select a password reminder question and enter the answer.
    5. Select a security image, then
      Create My Account

    5. Assign
      the Okta Verify application you added in Step 2.
    6. After the application has been
      , click
    7. Repeat this process for all groups that will use the Okta Verify application for MFA.
  4. Add users and assign them to a group.
    1. From the Okta Dashboard, select

    2. Enter the user’s
      First Name

        View Certificate
        Copy to File
      • Firefox
        Privacy & Security
        View Certificates
      • Internet Explorer
        Internet Options
    2. Use the Certificate Export Wizard to export all certificates in the chain and select
      Base-64 encoded X.509
      as the format.

Configure the firewall to integrate with Okta

As a prerequisite, confirm that you have mapped all users that you want to authenticate using Okta.
  1. Import all certificates in the certificate chain on the firewall and add the imported CA certificates (root and intermediate) to a Certificate Profile.
  2. Add a
    Multi Factor Authentication Server Profile
    for Okta.
    1. Select
      Server Profiles
      Multi Factor Authentication
    2. Add
      an MFA server profile.
    3. Enter a
      Profile Name
    4. Select the
      Certificate Profile
      you created in Step 1 in Configure the firewall to integrate with Okta.
    5. Select
      Okta Adaptive
      as the
      MFA Vendor
    6. Enter the
      API Host
      , and
      from Step 4 in Configure the firewall to integrate with Okta.
  3. Configure Authentication Portal using
    Redirect Mode
    to redirect users to the MFA vendor’s challenge.
  4. Enable response pages on the Interface Management Profile to redirect users to the response page challenge.
  5. Create an Authentication Profile and add the MFA vendor as a
    (see Configure Multi-Factor Authentication, Step 3.)
  6. Enable User-ID on the source zone to require identified users to respond to the challenge using your MFA vendor.
  7. Create an Authentication Enforcement Object to use the MFA vendor and create an Authentication policy rule (see Configure Authentication Policy, Steps 4 and 5).
  8. Commit
    your changes.

Verify MFA with Okta

  1. Verify your users received their enrollment emails, have activated their accounts, and have downloaded the Okta Verify app on their devices.
  2. Go to a website that will prompt the response page challenge.
    If you are using a self-signed certificate instead of a PKI-assigned certificate from your organization, a security warning displays that users must click through to access the challenge.
  3. Log in to the response page using your Okta credentials.
  4. Confirm the device receives the challenge push notification.
  5. Confirm users can successfully access the page after authenticating the challenge by accepting the push notification on their devices.
