178: Deploy MDM based policies for EDR/AV

Overview​

Deploying MDM-based policies for Endpoint Detection and Response (EDR) and Antivirus (AV) on macOS devices using Microsoft Intune involves several steps. Here's a detailed overview:

Steps to Deploy MDM-Based Policies for EDR/AV on macOS​

  1. Prerequisites and System Requirements:

    • Ensure you have the necessary licenses for Microsoft Defender for Endpoint.
    • Verify that macOS devices meet the system requirements¹.

  2. Create System Configuration Profiles:

    • In the Intune admin center, navigate to Devices > Configuration profiles.
    • Create profiles for system extensions, network extensions, full disk access, and other necessary configurations.

  3. Approve System Extensions:

    • Go to Devices > Configuration profiles and create a new profile.
    • Select macOS as the platform and Extensions as the profile type.
    • Add the required system extensions.

  4. Deploy Microsoft Defender for Endpoint:

    • Download the onboarding package from the Microsoft Defender Security Center.
    • Deploy the package using Intune by creating a new app and assigning it to the relevant device groups.

  5. Configure EDR Policies:

    • In the Intune admin center, go to Endpoint security > Endpoint detection and response.
    • Create and configure EDR policies, including onboarding packages and other settings.

Benefits​

  • Enhanced Security: Provides advanced threat detection and response capabilities, improving overall security posture.
  • Centralized Management: Simplifies the management of security policies across all macOS devices from a single console.
  • Compliance: Helps ensure devices comply with organizational security policies and regulatory requirements.

Drawbacks​

  • Complexity: Initial setup and configuration can be complex and time-consuming.
  • Resource Intensive: May require significant system resources, potentially impacting device performance.
  • User Experience: Users might experience interruptions during the deployment and configuration process.

Impact on End Users​

  • Performance: Users might notice a slight decrease in performance due to the additional security processes running in the background.
  • Notifications: Users will receive notifications related to security events and updates.
  • Access Restrictions: Some applications or actions might be restricted based on the security policies applied.

Tying to Zero Trust​

Deploying MDM-based policies for EDR/AV on macOS devices aligns with the Zero Trust security model by ensuring that:

  • Continuous Verification: Every access request is continuously verified, regardless of where the request originates.
  • Least Privilege Access: Users and devices are granted the minimum level of access necessary to perform their tasks.
  • Assume Breach: The system is designed with the assumption that a breach has already occurred, ensuring robust detection and response mechanisms.
