What is Conditional Access?

Conditional Access is a tool in Azure Active Directory that is used to make decisions that include user and device Id entity to enforce organizational policies. It’s an if-then statement.

Common signals

Common signals that Conditional Access can take in to account when making a policy decision include the following signals:

  • User or group membership
    • Policies can be targeted to specific users and groups giving administrators fine-grained control over access.
  • IP Location information
    • Organizations can create trusted IP address ranges that can be used when making policy decisions.
    • Administrators can specify entire countries IP ranges to block or allow traffic from.
  • Device
    • Users with devices of specific platforms or marked with a specific state can be used when enforcing Conditional Access policies.
  • Application
    • Users attempting to access specific applications can trigger different Conditional Access policies.
  • Real-time and calculated risk detection
    • Signals integration with Azure AD Identity Protection allows Conditional Access policies to identify risky sign-in behavior. Policies can then force users to perform password changes or multi-factor authentication to reduce their risk level or be blocked from access until an administrator takes manual action.
  • Microsoft Cloud App Security (MCAS)
    • Enables user application access and sessions to be monitored and controlled in real time, increasing visibility and control over access to and activities performed within your cloud environment.

Common decisions

  • Block access
    • Most restrictive decision
  • Grant access
    • Least restrictive decision, can still require one or more of the following options:
      • Require multi-factor authentication
      • Require device to be marked as compliant
      • Require Hybrid Azure AD joined device
      • Require approved client app
      • Require app protection policy (preview)

Commonly applied policies

Many organizations have common access concerns that Conditional Access policies can help with such as:

  • Requiring multi-factor authentication for users with administrative roles
  • Requiring multi-factor authentication for Azure management tasks
  • Blocking sign-ins for users attempting to use legacy authentication protocols
  • Requiring trusted locations for Azure Multi-Factor Authentication registration
  • Blocking or granting access from specific locations
  • Blocking risky sign-in behaviors
  • Requiring organization-managed devices for specific applications
