To configure Microsoft Defender Antivirus for session hosts, you need to have an Azure account, a host pool, and the FantasySports virtual machine (VM). Please verify that your VM is part of a host pool.
Steps to Configure Microsoft Defender Antivirus for session hosts
Step 1: Enable Microsoft Defender Antivirus
First, you need to make sure that Microsoft Defender Antivirus is enabled on your session hosts. You can do this through Group Policy, PowerShell, or by using the Set-MpPreference cmdlet.
Example:
PowerShell
Set-MpPreference -DisableRealtimeMonitoring $false
Step 2: Configure Antivirus Scan Preferences
Now you need to define AV scan preferences. These configurations include schedule scan, customizing scan settings, allow user to pause scan and others.
Example:
PowerShell
Set-MpPreference -ScanType QuickScan
This command sets a quick scan setting.
Step 3: Configure Antivirus Actions
Next, decide on the action that Microsoft Defender Antivirus will take when it detects malware. You can decide whether you want to clean, quarantine, remove, or allow the malware.
Example:
PowerShell
Set-MpPreference -ThreatDefaultAction Clean
The above command sets the default action to clean.
Step 4: Configure Real-time Protection Settings
Real-time protection is a feature that allows Microsoft Defender Antivirus to alert you when malware, spyware, or other potentially unwanted software attempts to install itself or run on your PC.
Example:
PowerShell
Set-MpPreference -EnableControlledFolderAccess Enabled
The above command enables Controlled Folder Access – a feature that protects valuable data from malicious apps and threats, such as ransomware.
Step 5: Optimizing Antivirus for session-based virtual desktop infrastructure
Due to the unique nature of session-based virtual desktop infrastructures (VDI), it is important to consider settings and configurations that optimize performance. These recommendations include, but are not limited to, limiting scheduled scans during specific hours, excluding specific pathways and processes from scans, and turning off unnecessary features for session hosts.
Example:
PowerShell
Set-MpPreference -ExclusionExtension “.log”,”.dat”
The above command sets the antivirus to exclude the files with .log and .dat extensions.
Conclusion
Proper configuration of Microsoft Defender Antivirus provides a seamless and secure experience for users on Azure Virtual Desktop infrastructures. Best practices for configuration involve enabling real-time monitoring, deciding on default actions upon detection of malware, scheduling recurrent quick scans, and optimizing the setting to suit your specific VDI environment.
Remember that the specific needs of your organization and the unique nature of the host environment ultimately dictate your configuration choices. Therefore, while these detailed steps provide a guide, they may not cover all aspects of your personalized configuration.
In preparing for the AZ-140 exam, understanding the configuration and operation of Microsoft Defender Antivirus is crucial. With diligent practice and understanding of concepts, you’re one step closer to acing the exam!
