Azure AD Conditional Access Deep Dive

Understanding the Core Concepts

Conditional Access is a key component of Azure AD's security capabilities. It allows you to define specific rules and policies that determine whether a user or device is authorized to access protected resources.

Different policies cater to various risk levels – low, medium, and high.

Key Policy Types

• Least Privilege: Users and devices are granted only the minimum permissions required to perform their tasks.
• Conditional Access Policies: Define rules based on device, location, user risk, and application.
• Device Compliance: Ensures devices meet specific security requirements before granting access.
• User Risk: Adjusts access based on user behavior, device state, and location.

Key Configuration Elements

Azure AD Identity Policy: Defines what a user can do. Azure AD Conditional Access Policy: Determines whether access is granted or denied. Device Compliance Policy: Ensures device security configurations. User Risk Policy: Determines Access Based on user risk profile. Location Policy: Defines how access is granted based on the user’s location.

Example Scenario: Requiring MFA for Remote Access

A user is attempting to access a resource remotely. Conditional Access policy requires MFA authentication to verify the user's identity. This enhances security by reducing the risk of compromised credentials.

More Advanced Concepts

Attribute-Based Access Control (ABAC): A more granular control model that utilizes attributes (like user, device, location, and application) to define access rules.
