Intune RBAC & Windows Hello for Business

Not every admin should have the same power. Learn how Intune role-based access control limits who can do what, and how Windows Hello for Business replaces passwords with biometrics and PINs.

Who can do what in Intune?

Simple explanation

Think of Intune RBAC like hotel staff keys.

The general manager’s key opens every room, the restaurant, and the safe. A housekeeper’s key opens guest rooms but not the safe. A receptionist can check guests in but can’t enter rooms. Everyone has the access they need β€” and nothing more.

Intune works the same way. The IT director gets full access. The helpdesk gets β€œread device info + remote actions.” The app team gets β€œmanage apps only.” Nobody gets more access than their job requires.

Built-in Intune roles

Chen Wei at Meridian Bank has a team of 15 IT staff. He doesn’t want every team member to have the power to wipe 10,000 devices. Here are the built-in roles he uses:

RoleWhat They Can DoWho Gets It
Intune AdministratorEverything in IntuneChen Wei (IT Security Lead) only
Helpdesk OperatorView device/user info, perform remote actions (lock, sync, restart), reset passcodesHelpdesk team (5 staff)
Application ManagerManage apps: add, assign, update, delete. Can’t touch device policies.App deployment team (2 staff)
Endpoint Security ManagerManage security baselines, compliance policies, conditional access integrationSecurity team (3 staff)
Read Only OperatorView everything, change nothingAuditors, junior staff
Policy and Profile ManagerCreate and manage config profiles and compliance policiesDevice config team (2 staff)
School AdministratorManage devices and apps for education tenantsNot used at Meridian

Custom roles

If built-in roles don’t fit, you can create custom roles:

  1. Intune admin center β†’ Tenant administration β†’ Roles β†’ Create role
  2. Pick a name and description
  3. Select specific permissions (e.g., β€œRemote tasks: wipe = Yes, Remote tasks: retire = No”)
  4. Assign the role to a group with a scope group (limits which devices they manage)
Exam tip: scope tags and scope groups

RBAC in Intune has two scope concepts β€” don’t confuse them:

  • Scope groups = which users/devices the admin can manage (e.g., β€œonly devices in the Finance department”)
  • Scope tags = which Intune objects (policies, profiles, apps) the admin can see (e.g., β€œonly policies tagged β€˜Finance’”)

Together, they create fine-grained access: an admin might only manage Finance department devices AND only see Finance-tagged policies. This is especially useful in large orgs like Meridian Bank where different teams manage different business units.

Windows Hello for Business

What is it?

Simple explanation

Windows Hello for Business replaces your password with your face, fingerprint, or a PIN that never leaves your device.

Instead of typing a password that could be stolen, phished, or guessed, you unlock your device with something only you have (biometrics) or something tied to your specific device (a hardware-backed PIN). Even if someone sees your PIN, it only works on YOUR device.

Configuring Hello for Business with Intune

Chen Wei enables Hello for Business across all Meridian Bank devices:

  1. Intune admin center β†’ Devices β†’ Enrollment β†’ Windows Hello for Business

  2. Configure the tenant-wide settings:

    • Enable: Yes
    • Minimum PIN length: 6 (Chen Wei sets 8 for banking compliance)
    • Maximum PIN length: 127
    • Lowercase letters in PIN: Required
    • Uppercase letters in PIN: Required
    • Special characters in PIN: Allowed
    • PIN expiration: Not configured (Microsoft recommends against PIN expiration)
    • Use biometrics: Yes
    • Use TPM: Required
    • Allow phone sign-in: No (Chen Wei blocks this for security)
  3. Alternatively, create a device configuration profile or identity protection policy for group-specific settings

Deep dive: Hello for Business deployment models

There are several deployment models, and the exam may test awareness of them:

  • Cloud-only β€” simplest. Entra ID + Intune. No on-prem infrastructure. Best for cloud-native orgs like CloudForge.
  • Hybrid key trust β€” uses Entra ID + on-prem AD + Entra Connect. The on-prem DC validates the key. Common during migration.
  • Hybrid certificate trust β€” adds PKI (certificate authority). The on-prem DC validates a certificate. More complex, needed for RDP scenarios.
  • On-premises key trust β€” purely on-prem AD with Windows Server 2016+. No cloud dependency.

For the exam, focus on: cloud-only is simplest, hybrid key trust is most common during migration, all models require TPM 1.2 or later.

Question

What's the difference between scope tags and scope groups in Intune RBAC?

Click or press Enter to reveal answer

Answer

Scope groups control WHICH devices/users an admin can manage. Scope tags control WHICH Intune objects (policies, profiles, apps) an admin can see. Together, they limit both the targets and the tools an admin can access.

Question

What makes Windows Hello for Business resistant to phishing?

Click or press Enter to reveal answer

Answer

It uses asymmetric key pairs where the private key is stored in the device's TPM and never transmitted during authentication. Even if an attacker intercepts the authentication flow, they can't replay or steal the credential.

Question

Which built-in Intune role should you assign to helpdesk staff?

Click or press Enter to reveal answer

Answer

Helpdesk Operator β€” it allows viewing device/user information and performing remote actions (lock, sync, restart, passcode reset) without the ability to modify policies, profiles, or app assignments.

Question

Does Microsoft recommend setting PIN expiration for Windows Hello for Business?

Click or press Enter to reveal answer

Answer

No. Microsoft recommends against PIN expiration. Since the PIN is hardware-backed (TPM) and only works on the specific device, it doesn't have the same risks as traditional passwords. Forcing rotation provides minimal security benefit.
