Azure Identity Protection

Azure Active Directory (Azure AD) Identity Protection helps organizations identify, assess, and respond to identity-based security risks. It leverages machine learning, Microsoft threat intelligence, and behavioral analytics to detect suspicious behavior that may indicate compromised accounts or malicious activity.

Identity Protection Policies

1. User Risk Policy

Purpose
Manages risks related to user accounts that are suspected of being compromised.

How It Works

• Assesses user risk levels based on indicators such as leaked credentials or abnormal behavior.

• Automatically applies remediation steps to accounts identified as risky.

Actions

• Require password reset: Users marked with high risk must reset their passwords before continuing access.

Best Practices

• Assign the policy to all users, excluding service accounts or emergency accounts if required.

• Regularly review risky users and investigate alerts to resolve issues promptly.

2. Sign-In Risk Policy

Purpose
Protects against risks associated with individual authentication attempts.

How It Works

• Detects risky sign-ins using signals such as:

  • Impossible travel (logins from geographically distant locations in a short time).

  • Sign-ins from unfamiliar devices or locations.

  • Access attempts from known malicious IP addresses or automated tools.

• Applies Conditional Access controls based on the detected risk level.

Actions

• Require multi factor authentication (MFA): Adds an extra verification step for risky sign-ins.

• Block access: Completely denies access for high-risk sign-in attempts.

Best Practices

• Require MFA for medium- and high-risk sign-ins.

• Continuously monitor sign-in data to identify patterns and fine-tune policy settings.

3. MFA Registration Policy

Purpose
Ensures that all users are enrolled in multifactor authentication.

How It Works

• Prompts users to complete MFA registration during their next sign-in.

• Enforces MFA enrollment to improve overall account security.

Actions

• Requires users who are not registered for MFA to complete the setup process.

Best Practices

• Apply this policy to all users, with special attention to privileged roles such as administrators.

• Use it alongside Conditional Access policies to consistently enforce MFA across the organization.
