Threat Management
Threat Management is a comprehensive approach to identifying, assessing, and mitigating security threats across the Windows ecosystem. It combines built‑in Windows capabilities, Microsoft Defender suite, and Azure services to provide end‑to‑end protection for devices, identities, data, and applications.
Key Capabilities
- Threat & Vulnerability Management (TVM) – Continuous discovery of vulnerabilities and misconfigurations.
- Endpoint Detection and Response (EDR) – Real‑time behavioral monitoring and automated remediation.
- Attack Surface Reduction (ASR) – Rules that block risky actions before they execute.
- Secure Score – A unified score that reflects your security posture.
- Automation & Orchestration – Integration with Microsoft Sentinel and Power Automate for automated playbooks.
Getting Started
- Enable Microsoft Defender for Endpoint on all devices.
- Configure Microsoft Defender for Cloud to protect workloads.
- Deploy ASR rules via Group Policy or Intune.
- Enable Secure Score and set baseline goals.
- Integrate alerts with Azure Sentinel for centralized monitoring.
Sample PowerShell Script – Deploy ASR Rules
# Requires admin rights
Import-Module Defender
$asrRules = @(
"D4F940AB-401B-4EFc-AADC-AD5F3C50688F", # Block executable content from email and web
"3B576869-A4EC-4529-852F-5EFA6AF2D3C8" # Block credential stealing from LSASS
)
foreach ($rule in $asrRules) {
Set-MpPreference -AttackSurfaceReductionRules_Ids $rule -AttackSurfaceReductionRules_Actions 1
}
Write-Host "ASR rules deployed successfully."
