Windows Defender Application Control – Intune Management Extension as Trusted Installer to prevent unwanted software installations

In the ever-evolving realm of digital threats, organizations face an increasingly complex landscape of security challenges. To effectively counter these risks, robust endpoint security solutions have become a necessity. Acknowledging this need, Microsoft is consistently working to enhance its security offerings. A notable stride in this direction is the introduction of the Intune Management Extension Trusted Installer for Windows Defender Application Control. This groundbreaking tool, managed through Microsoft Intune, equips organizations with heightened security capabilities and efficient management features. This article delves into the essence of the Intune Management Extension Trusted Installer, its mechanics, setup process, and the indispensable role it plays in fortifying an organization’s security infrastructure.

### Unveiling Intune Management Extension Trusted Installer

The Intune Management Extension Trusted Installer emerges as a fresh addition aimed at complementing the functionality of Windows Defender Application Control (WDAC) – a security solution that establishes application control policies, guarding endpoints against malicious and unauthorized software. The challenge lies in the intricate task of configuring and managing these policies across a sizable fleet of devices. Here’s where the Intune Management Extension Trusted Installer steps in, simplifying the management and deployment of WDAC policies.

### How It Works

The modus operandi of the Intune Management Extension Trusted Installer revolves around harnessing the capabilities of Microsoft Intune to streamline the process of deploying and managing WDAC policies. Here’s a succinct breakdown of its operational mechanism:

1. **Policy Creation:** Administrators craft WDAC policies within the Microsoft Endpoint Manager admin center, outlining the rules and constraints dictating the permissible applications on managed devices.

2. **Policy Distribution:** Once the policies are formulated, the Intune Management Extension Trusted Installer ensures their secure dissemination to the designated devices within the organization. This distribution exploits the robustness of Microsoft Intune’s cloud-based management infrastructure, guaranteeing a seamless and scalable process.

3. **Endpoint Evaluation:** At regular intervals, the Intune Management Extension Trusted Installer assesses the integrity of WDAC policies on the endpoints. It verifies the policies’ unaltered state, assuring ongoing compliance.

4. **Policy Enforcement:** When an endpoint undergoes a power cycle or restart, the Intune Management Extension Trusted Installer enforces the WDAC policies. This enforcement actively governs the execution of applications, thwarting any unauthorized or malicious software attempts and fortifying the organization’s overall security stance.

### Setting Up Intune Management Extension Trusted Installer

The process of configuring the Intune Management Extension Trusted Installer involves the following steps:

1. Access the Microsoft Intune admin center portal and navigate to “Endpoint security > Application control.”

2. On the “Managed Installer” tab, click “Add.”

3. Review the provided information and click “Add.”

4. Confirm the choice in the dialog box and click “Yes.”

5. Return to the “Application control” tab, and click “Create Policy.”

6. On the “Basics” page, assign a distinctive name to the policy for differentiation.

7. Proceed to the “Configuration settings” page, providing the necessary information.

8. Assign the policy to the designated device group and finalize the profile creation.

With the Intune Management Extension established as a managed installer and the Application Control policy applied, the setup concludes.

In conclusion, the Intune Management Extension Trusted Installer emerges as a pivotal advancement in the realm of endpoint security. Through its integration with Windows Defender Application Control, it streamlines the administration of security policies, empowering organizations to efficiently manage their security postures. By enhancing the ability to control application execution and safeguarding against unauthorized software, this tool exemplifies Microsoft’s commitment to equipping organizations with potent security solutions. As the digital landscape continues to evolve, embracing innovative tools like the Intune Management Extension Trusted Installer becomes a strategic imperative to navigate the dynamic challenges of cybersecurity.
