This document describes how to set up multi-factor authentication (MFA) for ServiceNow with AuthPoint as an identity provider. ServiceNow must already be configured and deployed before you set up MFA with AuthPoint.
ServiceNow can be configured to support MFA in several modes. For this integration, we set up SAML with AuthPoint.
ServiceNow Authentication Data Flow with AuthPoint
AuthPoint communicates with various cloud-based services and service providers with the SAML protocol. This diagram shows the data flow of an MFA transaction for ServiceNow.
Before You Begin
Before you begin these procedures, make sure that:
- End-users can log in to ServiceNow
- A token is assigned to a user in AuthPoint
- You have an AuthPoint identity provider (IdP) certificate (see Certificate Management)
To start, you must copy the metadata URL from the Certificate Management page in the AuthPoint management UI. After you have that, you can configure ServiceNow.
- Log in to WatchGuard Cloud.
- From the navigation menu, select Configure > AuthPoint. If you have a Service Provider account, you must select an account from Account Manager.
- Select Resources.
- Click Certificate.
- Next to AuthPoint certificate you will associate with your resource, click and select Copy Metadata URL. We recommend that you choose the certificate with the latest expiration date.
The AuthPoint metadata provides your resource, in this case ServiceNow, with information necessary to identify AuthPoint as a trusted identity provider.
- Log in to ServiceNow as the system administrator.
- In the filter navigator, search for plugins.
The Plugins page appears.
- In the search bar at the top of the Plugins page, search for com.snc.integration.sso.multi.
- For Integration - Multiple Provider Single Sign-On Enhanced UI and Integration - Multiple Provider Single Sign-On Installer, click Install > Activate.
- Go to the list of plugins and confirm that both Multiple Provider Single Sign-On integrations (Installer and Enhanced UI) have the Active status.
- In the filter navigator, search for Multi-Provider SSO.
- Select Administration > Properties.
- For Enable multiple provider SSO, select Yes.
- For user identification, type email. This replaces the default user_name value.
- Click Save.
- Select Multi-Provider SSO > Identity Providers > New.
- For the kind of SSO, select SAML.
The Import Identity Provider Metadata window appears.
- Select URL.
- In the Enter the URL text box, paste the metadata URL that you copied from AuthPoint.
- Click Import.
- Scroll down and select the Encryption And Signing tab.
- In the Signing/Encryption Key Alias text box, type saml2sp. Leave the default value for all other settings.
- Select the User Provisioning tab.
- Clear the Auto Provisioning User and Update User Record Upon Each Login check boxes.
- Select the Advanced tab.
- Select the Create AuthnContextClass check box. Leave the default values for all other settings.
- Click Generate Metadata.
- On the Service Provider Metadata page, find and copy the Service Provider entityID and Assertion Consumer Service values. You need these values to create a SAML resource in AuthPoint in the next section.
- Click the Additional Actions icon (hamburger menu) and select Copy sys_id. Paste the copied value in a note so you can reference it in a later step.
- Click Update.
- To create a new user, select User Administration > Users > New.
- In the Email text box, type the email address associated with your AuthPoint user account.
- Click Submit.
- Select the user you just created.
- Click the Additional Actions icon (hamburger menu) and select Configure > Form Design.
- From the Fields section, select and drag the SSO Source field to the User [sys_user] list.
- Click Save.
- Close the Form Design page and go back to the user configuration page.
- In the SSO Source text box, type sso: and then paste the sys_id value that you copied in Step 23. Do not add a space between sso: and the sys_id value.
- Click Update.
- From the navigation menu, select Multi-Provider SSO > Identity Providers.
- Select the identity provider name you created before.
- Click Test Connection.
- After a successful connection test, click Activate.
Before AuthPoint can receive authentication requests from ServiceNow, you must create a SAML resource in AuthPoint. You must also assign an access policy for the ServiceNow resource to the user group(s) that must authenticate to log in.
Add a SAML Resource in AuthPoint
From the AuthPoint management UI:
- From the navigation menu, select Resources.
- From the Choose a Resource Type drop-down list, select SAML. Click Add Resource.
- In the Name text box, type a name for this resource. In our example, we name the resource ServiceNow.
- From the Application Type drop-down list, select ServiceNow.
- In the Service Provider Entity ID text box, type https://yourdomain.service-now.com.
- In the Assertion Consumer Service text box, type https://yourdomain.service-now.com/navpage.do.
- From the User ID sent on redirection to service provider drop-down list, select Email.
- In the Logout URL text box, type https://yourdomain.service-now.com/navpage.do.
- From the Signature Method drop-down list, select SHA-256.
- From the AuthPoint Certificate drop-down list, select the certificate to associate with your resource. This must be the same certificate that you downloaded the metadata for in the previous section.
- Click Save.
Add an Access Policy to AuthPoint
You must have at least one user group in AuthPoint for authentication with ServiceNow, and you must assign an access policy for the ServiceNow resource to that group. If you already have a group, you do not have to add another group.
In the AuthPoint management UI:
- From the navigation menu, select Groups.
- To add a new group, click Add Group. If you already have a group that you want to use, select the group to edit it.
- In the Name text box, type a descriptive name for the group.
- (Optional) In the Description text box, type a description of the group.
- In the Access Policy section, click Add Policy.
- In the Add Policy dialog box, from the Resource drop-down list, select the resource you want to add an access policy for.
- (Optional) To require that users type their password before they authenticate for this resource, enable the Require Password Authentication toggle.
- Select the authentication options that users in this group can select from when they authenticate.
For SAML resources, if you select more than one authentication option, users must select one of the available options when they authenticate. For example, if you select OTP and Push, users can choose to type their OTP or approve a push to authenticate. You cannot require that they do both.
- Click Add.
- (Optional) Add one or more safe locations to your group. For more information about safe locations and detailed instructions to add them, see About Safe Locations.
- Click Save.
Add Users to AuthPoint
Before you assign users to a group, you must add the users to AuthPoint. There are two ways to add AuthPoint user accounts:
- Sync users from an external user database
- Add local AuthPoint users
Each user must be a member of a group. You must add at least one group before you can add users to AuthPoint.
To import users from Active Directory, Azure Active Directory, or an LDAP database, you must add an external identity in the AuthPoint management UI. External identities connect to user databases to get user account information and validate passwords.
- To sync users from Active Directory or an LDAP database, you must add an LDAP external identity
- To sync users from Azure Active Directory, you must add an Azure AD external identity
When you sync users from an external user database, you can sync any number of users and they are all added to AuthPoint at one time. Users synced from an external user database use the password defined for their user account as their AuthPoint password.
You can create local AuthPoint users on the Users page in the AuthPoint management UI. Because you can create only one user at a time, you most commonly do this when you want to create test users or to add only a small number of users.
Unlike users synced from an external user database, local AuthPoint users define and manage their own AuthPoint password. When you add a local user account, the user receives an email that prompts them to set their password.
To learn how to add local AuthPoint user accounts, see Add Local AuthPoint Users.
Test the Integration
To test AuthPoint MFA with ServiceNow, you can authenticate with a mobile token on your mobile device. For SAML resources, you can choose any method (push, QR code, or one-time password).
In this example, we show the push authentication method (users receive a push notification in the mobile app that they must approve to authenticate).
- In a web browser, go to the ServiceNow URL.
- Click Use external login.
- In the External login section, type your email address. Click Submit.
- Type your email address or AuthPoint user name. Click Next.
- If required, in the Password text box, type your password.
- For the authentication method, select Send Push.
- Approve the authentication request that is sent to your mobile device.
You are logged in to ServiceNow.
