How can MSPs enhance security in Entra ID?

Written by Infini East | Mar 6, 2025 3:24:31 PM

MSPs can enhance security in Entra ID (formerly Azure AD) by implementing best practices around identity protection, access management, and governance. Here’s a comprehensive approach:

1. Enable Multifactor Authentication (MFA)

  • Use Conditional Access to enforce MFA for all users, especially admins.
  • Enable phishing-resistant MFA methods like FIDO2 security keys or Microsoft Authenticator’s number matching.

2. Implement Conditional Access Policies

  • Block access from risky sign-ins and unknown locations.
  • Require compliant devices for sensitive applications.
  • Enforce Just-In-Time (JIT) access for admins.

3. Use Entra ID Protection

  • Detect and respond to compromised identities.
  • Enable risk-based sign-in policies to block high-risk users.
  • Automate user risk remediation.

4. Secure Privileged Access with Entra ID PIM

  • Implement Privileged Identity Management (PIM) to provide Just-In-Time (JIT) admin access.
  • Require approval workflows for privileged role activation.
  • Enforce MFA for admin role activation.

5. Monitor & Audit with Entra ID Logs

  • Enable audit logs and integrate with SIEM solutions like Microsoft Sentinel.
  • Set up alerts for suspicious activities (e.g., mass password resets, impossible travel).
  • Regularly review access logs for anomalies.

6. Implement Least Privilege Access (Zero Trust)

  • Assign users only the roles they need (RBAC model).
  • Regularly review and remove unnecessary access.
  • Use Access Reviews for periodic role validation.

7. Secure Guest & External Access

  • Limit guest user permissions with external collaboration settings.
  • Require MFA for guest users.
  • Restrict external sharing of sensitive data.

8. Enable Passwordless Authentication

  • Implement Windows Hello for Business, FIDO2 security keys, or Passkeys.
  • Reduce password reliance to mitigate phishing risks.

9. Protect Against Legacy Authentication

  • Disable legacy authentication (e.g., SMTP, POP, IMAP).
  • Enforce Modern Authentication for all apps.

10. Use Defender for Identity & Microsoft Sentinel

  • Deploy Defender for Identity to detect identity-based threats.
  • Integrate Entra ID logs with Microsoft Sentinel for real-time threat hunting.

Key Takeaway for MSPs

By implementing Zero Trust principles, enforcing Conditional Access policies, and leveraging Microsoft’s security tools, MSPs can significantly reduce identity-related risks in Entra ID.
