Defender Antivirus Policy Modification

This guide will provide background information on modifying an existing set of Windows Defender settings.

Defender Antivirus

Microsoft Defender Antivirus is a built-in antivirus for Windows OS that protects against all types of malware. It works with Microsoft Defender for Endpoint to provide protection on the device and in the cloud. It is deployable through Intune MDM, which allows a deep configuration scope of scan type, enforcement levels, and duration as well as the ability to restrict end user interference with the security controls which will harden the systems from tampering incidents.
