Two-Factor Authentication (2FA/MFA) for BeyondTrust

---

BeyondTrust is a software and protocol which uses techniques to provide security to site-to-site connections. Also, it secures a point-to-point connection. You can enable two-factor authentication (2FA) for your BeyondTrust managed active directory to increase security level. When you enable 2FA, your users enter their username and password (first factor) as usual, The configured 2FA (OTP over SMS, Push Notifications, Google Authenticator etc) method prompts on for 2nd-step verification. After successfully signing in with both of the steps a user is granted access to the beyond trust account. This additional verification layer acts as a security measure and prevents unauthorized people from accessing the Beyond trust account by verifying your identity even if cyber attackers get to know your credentials.

Types of 2FA Authentication with RADIUS

The 2-factor authentication can be of two types depending on the clients.

• Clients that support RADIUS Challenge.
• Clients that do not support RADIUS Challenge.

miniOrange 2FA authentication for BeyonTrust Login

miniOrange accomplishes this by acting as a RADIUS server that accepts the username/password of the user entered as a RADIUS request and validates the user against the user store as Active Directory (AD). After the first level of authentication, miniOrange prompts the user with 2-factor authentication and either grants/revokes access based on the input by the user.

• Primary authentication initiates with the user submitting his Username and Password for BeyonTrust .
• User request acts as an authentication request to RADIUS Server(miniOrange).
• miniOrange RADIUS server passes user credentials to validate against the credentials stored in AD (Active Directory) / Database.
• Once the user's first level of authentication gets validated AD sends the confirmation to RADIUS Server.
• Now miniOrange RADIUS Server asks for a 2-factor authentication challenge to the user.
• Here user submits the response/code which he receives on his hardware/phone.
• User response is checked at miniOrange’s RADIUS Server side.
• On successful 2nd factor authentication the user is granted access to BeyondTrust .

  Palo Alto VPN	26 Vendor-Specific	25461	5
  SonicWall VPN	26 Vendor-Specific	8741	3
  Citrix VPN	26 Vendor-Specific	66	16

• Configure the following Policy details for the Radius Client.




Group Name:	Group for which the policy will apply.
Policy Name:	Any Identifier that specifies policy name.
Login Method	Login Method for the users associated with this policy.
Enable 2-Factor Authentication	Enables Second Factor during Login for users associated with this policy.
Enable Adaptive Authentication	Enables Adaptive Authentication for Login of users associated with this policy.

• After configuring the given above details, Click on Save button.
Note: You can follow this guide, if you want to configure Radius MFA using MSCHAPv2 protocol.

NOTE: For On-Premise version follow the below steps before testing the connectivity.



Only For On-Premise Version

Open Firewall Ports.

• In order to receive the RADIUS request, it is necessary to open UDP traffic on ports 1812 and 1813 for the machine where On-Premise IdP is deployed.
• If the hosting machine is a Windows Machine then you can follow this document.
• If the hosting machine is a Linux Machine then you can follow this document.

NOTE: If your machine is hosted on AWS, then enable the ports from the AWS panel.

2. Configure BeyondTrust Server

• Open your BeyondTrust Server Admin Dashboard
• Go to Users & Security > Security Providers.
• From + Add option under Security Providers select RADIUS.



• You can choose to allow access only to specified users on your RADIUS server by entering username separated by a line break.
• To edit gropu policies go to Users & Security > Group Policiess. page.
• If you allow all, you must also specify a default group policy.

Name:	miniOrange RADIUS
Selected modules:	Add the "RADIUS" module from the "Available modules" box
Selected policies:	Add the desired policies from the "Available policies" box

RADIUS server:	For on-premise version: IP of server where IDP(miniOrange) is installed For cloud version: Contact us at info@xecurify.com to get the IP
Port:	Specify the authentication port for your RADIUS server. This is typically port 1812.
Timeout (seconds):	An ideal value is 3-5 seconds, with the maximum value at three minutes.
Shared Secret:	Security Key that was configured in miniOrange IDP. In step 1 we configured this as "sharedsecret"

• Click on Save Changes button to save the RADIUS settings.

Creating User Groups (Recommended)

• AD user group
• miniOrange user group

• This step involves Importing the user group from the Active Directory and Provisioning them.
• Go to Provisioning. Switch to Setup Provisioning tab and select Active Directory from Dropdown menu.



• Select Group Provisioning/Deprovisioning tab, and toggle on Import Group option.
• Enter the Base DN for group sync and click Save.



• If you want to dynamically allocate users to the groups present in the miniOrange, then enable "Assign Users to groups"



• Now switch to Import Groups option and select Active Directory from which you want to import your users.
• Finally, click on Import button. Your group will be imported.




(The Active Directory Group Provisioning (Sync) setup is done. Now, whenever a user is created or modified in LDAP server and if the Assign Users to groups is enabled, then user group attribute from the LDAP server will be automatically synced and the user group will be assigned or changed accordingly in miniOrange.)

• Select Groups >> Manage Groups from left panel.
• Click on the Create Group button on the top.



• Enter an appropriate Group Name and click on Create Group.



• In this guide we have created a Group by name VPN_Group.
• Assign various members to the group using the Assign User option associated with the group in the groups list.



• Select the Users that are required to be assigned to this group. Then Select Assign to Group in Select Action Dropdown and click on Apply button.



• These groups will be helpful in adding multiple 2FA policies on the applications.

7. Setup MFA for BeyonTrust

• Here, we will configure a policy for the User Group that we created in this step and associate it with the BeyonTrust VPN Application.
• Click on Policies tab >> App Login Policy.



• Click on Add Policy tab.
• In Application section, select the RADIUS App that we configured earlier in Step 1.
• Select the required User Group in Group Name and enter the Policy name.
• In this guide, we will configure a Password Only policy for "VPN_Group", so that only the VPN_Group members can access VPN Services without a Second Factor.
• Once done with the policy settings, click on Save to Add Policy.

8. Test 2FA for BeyondTrust Login

• Connect to the URL you normally use to log in to your BeyondTrust .
• Enter your AD username & password and click on Connect.
• Now, you will be prompted for the 2-factor authentication code. Enter the code and click on Continue.
• After successful validation, you will be connected to BeyondTrust .
