MDE Kit: A PowerShell Module for Microsoft Defender for Endpoint

MDE Kit

MDE Kit’s objective is to help automate and empower your investigation, detection, prevention, and response capabilities leveraging the MDE API. MDE Kit leverages many of the available Microsoft Defender for Endpoint (MDE) APIs to take response actions on machines as well as create reports related to TVM data, alert data, antivirus data, and machine data. More details about each function can be found below. Learn more about this project at my blog: MDEKit PowerShell Module

Get-MdeKitHelp

This function will provide a brief description of MDEKit as well as a list of available functions. To learn more about each function, simply enter “Get-Help (function name)”.

Get-SecureConfigAssessment

Get-SecureConfigAssessment leverages the Export secure configuration assessment per device API. Like all of the other “Get” functions in this module, you can run this without any parameters to get all security configuration assessment data per device. Or you can specify any of the parameters found in the Properties table of the above documentation. For example, if you wish to only return configuration data where the impact level is 9 or 10, you can enter “Get-SecureConfigAssessment -ConfigurationImpact 9,10”. Additionally, you can use the -Path or -P parameter to send output to a CSV file locally. You can also specify the -Quiet or -Q parameter if you wish to omit output to the PowerShell console.

Get-SoftwareInventoryAssessment

Get-SoftwareInventoryAssessment leverages the Export software inventory assessment per device API. Like all of the other “Get” functions in this module, you can run this without any parameters to get all software inventory assessment data per device. Or you can specify any of the parameters found in the Properties table of the above documentation. For example, if you wish to only return software inventory data where the software vendor is Microsoft, you can enter “Get-SoftwareInventoryAssessment -SoftwareVendor ‘Microsoft'”. Additionally, you can use the -Path or -P parameter to send output to a CSV file locally. You can also specify the -Quiet or -Q parameter if you wish to omit output to the PowerShell console.

Get-NonCpeSoftwareInventoryAssessment

Get-NonCpeSoftwareInventoryAssessment leverages the Export non product code software inventory assessment per device API. Like all of the other “Get” functions in this module, you can run this without any parameters to get all of the non-CPE software inventory data per device. Or you can specify any of the parameters found in the Properties table of the above documentation. For example, if you wish to only return non-CPE software inventory data where the vendor is Microsoft and the OS platform is Windows 11, you can enter “Get-NonCpeSoftwareInventoryAssessment -SoftwareVendor ‘Microsoft’ -OsPlatform ‘Windows11′”. Additionally, you can use the -Path or -P parameter to send output to a CSV file locally. You can also specify the -Quiet or -Q parameter if you wish to omit output to the PowerShell console.

Get-SoftwareVulnerabilitiesAssessment

Get-SoftwareVulnerabilitiesAssessment leverages the Export software vulnerabilities assessment per device API. Like all of the other “Get” functions in this module, you can run this without any parameters to get all of the software vulnerability assessment data. Or you can specify any of the parameters found in the Properties table of the above documentation. For example, if you wish to only return software vulnerabilities where the severity level is high and where the exploitability level is exploit verified, you can enter “Get-SoftwareVulnerabilitiesAssessment -VulnerabilitySeverityLevel ‘high’ -ExploitabilityLevel ‘ExploitIsVerified'”. Additionally, you can use the -Path or -P parameter to send output to a CSV file locally. You can also specify the -Quiet or -Q parameter if you wish to omit output to the PowerShell console.

Get-Machines

Get-Machines leverages the List Machines API. Like all of the other “Get” functions in this module, you can run this without any parameters to get all of the machine data. Or you can specify any of the parameters found in the Properties table of the above documentation. For example, if you wish to only return machines in the Domain Controllers device group, you can enter “Get-Machines -RbacGroupName ‘Domain Controllers'”. Additionally, you can use the -Path or -P parameter to send output to a CSV file locally. You can also specify the -Quiet or -Q parameter if you wish to omit output to the PowerShell console.

Get-Alerts

Get-Alerts leverages the List Alerts API. Like all of the other “Get” functions in this module, you can run this without any parameters to get all of the alert data. Or you can specify any of the parameters found in the Properties table of the above documentation. For example, if you wish to only return alerts related to a user named Darth Vader, you can enter “Get-Alerts -RelatedUser ‘Darth Vader'”. Additionally, you can use the -Path or -P parameter to send output to a CSV file locally. You can also specify the -Quiet or -Q parameter if you wish to omit output to the PowerShell console.

Get-AvInfo

Get-AvInfo leverages the Export device antivirus health report API. Like all of the other “Get” functions in this module, you can run this without any parameters to get all of the AV data. Or you can specify any of the parameters found in the Properties table of the above documentation. For example, if you wish to only return AV info where the platform version is unknown or not up to date, you can enter “Get-AvInfo -AvIsPlatformUpToDate ‘False’,’Unknown'”. Additionally, you can use the -Path or -P parameter to send output to a CSV file locally. You can also specify the -Quiet or -Q parameter if you wish to omit output to the PowerShell console.

Get-Recommendations

Get-Recommendations leverages the List All Recommendations API. Like all of the other “Get” functions in this module, you can run this without any parameters to get all of the TVM recommendation data. Or you can specify any of the parameters found in the Properties table of the above documentation. For example, if you wish to only return recommendations with a severity score of 10 and a remediation type of “uninstall”, you can enter “Get-Recommendations -SeverityScore 10 -RemediationType ‘Uninstall'”. Additionally, you can use the -Path or -P parameter to send output to a CSV file locally. You can also specify the -Quiet or -Q parameter if you wish to omit output to the PowerShell console.

Get-Vulnerabilities

Get-Vulnerabilities leverages the List All Vulnerabilities API. Like all of the other “Get” functions in this module, you can run this without any parameters to get all of the TVM vulnerabilities data. Or you can specify any of the parameters found in the Properties table of the above documentation. For example, if you wish to only return vulnerabilities for a specific CVE, you can enter “Get-Vulnerabilities -id ‘CVE-2023-20955′”. Additionally, you can use the -Path or -P parameter to send output to a CSV file locally. You can also specify the -Quiet or -Q parameter if you wish to omit output to the PowerShell console.

Show-MachineActionsMenu

Show-MachineActionsMenu leverages many of the response action APIs made available by MDE. These actions include:

• Collect investigation packages

• Isolate or unisolated machines

• Run live response

• Restrict or unrestricted applications

• Run antivirus scans

• Offboard machines

• Stop and quarantine files

• Cancel pending machine action

  Essentially this function is one which I previously wrote and blogged about and have reused in this module. To learn the ins and outs of this function, you can read that blog here: Taking Actions on MDE Devices with PowerShell
