Block Edge Browser Native Messaging Feature using Intune Security Policy to Avoid Backdoor Attacks #msintune
Intune Security Policy to Avoid Backdoor Attacks while using Edge Browser Native Messaging Feature
00:00 - 00:12: Introduction
The video starts with an intro graphic for "Daily the Intune Tips."
The speaker introduces the topic for the day: a browser security feature called "Native Messaging."
00:12 - 00:26: What You Will Learn
The speaker outlines the video's goals: to understand the good and bad aspects of Native Messaging and how to control it using Microsoft Intune to improve security.
00:26 - 01:09: Explaining "Good" Native Messaging (The Use Case)
00:26: The speaker presents a common scenario: a browser extension for a password manager (in Chrome or Microsoft Edge).
00:35: He explains that this extension needs to connect to the "native" Windows application of the password manager to retrieve details.
00:49: Native Messaging is defined as the technology that allows this communication between a browser extension and a local application on your computer.
01:09 - 01:40: Explaining "Bad" Native Messaging (The Security Risk)
01:18: The video shows a "Good vs. Bad" comparison graphic, highlighting that while useful for things like password managers and antivirus, there's a downside.
01:26: The speaker explains that malware extensions can also use this same Native Messaging technology to perform malicious actions on the computer.
01:40 - 02:25: The Solution: How to Block Native Messaging with Intune
01:40: The speaker poses the question of how to prevent this misuse and introduces the solution: using a Microsoft Intune settings catalog policy.
01:49: The screen shows the Intune "Settings picker" interface.
01:56: The speaker demonstrates the navigation path: Go to Settings Catalog, search for the Microsoft Edge browser category, and find the Native Messaging subcategory.
02:07: He points out the specific policy: "Allow user-level native messaging hosts." The video shows how to set this policy to "Disabled."
02:14: The speaker quickly goes through the final steps of creating the profile: assigning it to a group of devices and creating the policy.
02:26 - 02:29: Conclusion
The speaker signs off, hoping the tip was helpful.
In this Intune tip, we'll explore the Native Messaging feature in web browsers like Google Chrome and Microsoft Edge. Learn about its legitimate uses, such as enabling communication between browser extensions (like password managers) and native applications on your computer.
We'll also discuss the potential security risks, as malware can exploit this technology to perform malicious actions.
Most importantly, we'll walk you through a step-by-step guide on how to enhance your browser security by using Microsoft Intune to control and disable user-level native messaging.
Stay ahead of security threats and learn how to manage your devices effectively with our daily Intune tips!

Imagine your web browser, like Google Chrome or Microsoft Edge, needs to talk to a software on your computer. For example, your password manager extension needs to connect to the main password manager application.
Native Messaging is the technology that allows this communication. It creates a bridge between your browser extension and a local application on your machine. This is very useful for applications that need to do more than a simple web page can, like managing passwords or protecting your computer from viruses.
On one side, it is very helpful. Legitimate and trusted applications use it to provide important services and security features directly in your browser.
But, on the other side, it can be a security risk. If you accidentally install a malicious extension, it could use Native Messaging to communicate with malware on your computer. This can happen without needing special administrator permissions. This malware can then steal your data, like passwords and personal files, or gain more control over your computer. This is a backdoor that we need to close.
By setting up this policy, we tell Microsoft Edge to only allow native messaging from applications that have been installed by an administrator. This is a key step in "security hardening." It means we are making the browser stronger against attacks.
