By searching on the Internet, I found a few posts mentioning that Tamper Protection could help us to solve this issue. Tamper Protectionįirst, let’s have a look at Tamper Protection. How can we prevent users from adding exclusions? We can? Right? We will go over different possibilities in Microsoft Defender for Endpoint to do so. Indeed, we want to prevent that users help themselves to install suspicious software and we don’t want attackers that would have gained sufficient privileges to add exclusions so that they can install and run their malicious payloads. By default, standard users can’t change, add or remove exclusions. Therefore, it is a best practice to keep them as limited as possible and to review them periodically.īecause these are protection gaps, you don’t want users from adding exclusions locally on their laptop. Indeed, the more exclusions there are, the larger the attack surface is. Although they can be useful to benefit from the protection capabilities while preventing any impact on end users and business flows, they represent a protection gap.

These features include cloud-delivered and real-time protection with behavioral, heuristic and machine learning-based protection.īecause some business applications might be blocked by these capabilities, there is the possibility to create specific exclusions for files, processes and processed-opened files from Microsoft Defender Antivirus scans, real-time protection and monitoring. Microsoft Defender Antivirus comes with different features that can be configured using Microsoft Endpoint Manager (MEM)/Intune, Group Policy, PowerShell, etc.

What capabilities in Microsoft Defender Antivirus can help us? However, after doing some research and tests in a lab environment, I discovered that it might not be as easy as I thought.

I first thought it was going to be pretty easy by pushing some settings via Microsoft Endpoint Manager. A few weeks ago, I got a question from a client to check how they could prevent administrators, including local administrators on their device, to add exclusions in Microsoft Defender Antivirus.
