Introduction:

Microsoft has introduced Security Copilot agents in Microsoft Purview (preview), leveraging AI to automate and scale Data Loss Prevention (DLP) and Insider Risk Management (IRM) workflows. This innovation enhances threat detection and response by integrating AI-driven automation into security operations.

Learning Objectives:

  • Understand how Security Copilot agents streamline DLP and IRM triage.
  • Learn key commands and configurations for deploying AI-driven security automation.
  • Explore best practices for integrating Security Copilot with existing Microsoft Purview policies.

1. Enabling Security Copilot in Microsoft Purview

Command/PowerShell:

Connect-AIPService -IdentitySecurityPath "SecurityCopilot" 
Enable-SecurityCopilotAgent -PolicyScope "DLP,IRM"

Step-by-Step Guide:

  1. Connect to the AIPService using PowerShell with admin privileges.
  2. Enable the Security Copilot agent for DLP and IRM policies.

3. Verify activation via:

Get-SecurityCopilotStatus

2. Configuring DLP Policies with Security Copilot

Microsoft Purview Portal Command:

New-DlpCompliancePolicy -Name "Copilot_Enhanced_DLP" -Labels "Confidential" -Action "BlockWithCopilotReview"

Steps:

  1. Navigate to Microsoft Purview Compliance Portal > Data Loss Prevention.
  2. Create a new DLP policy with the BlockWithCopilotReview action.
  3. Assign sensitivity labels (e.g., “Confidential”) for automated triage.

3. Automating Insider Risk Alerts

KQL Query for IRM:

SecurityIncident 
| where IncidentType == "InsiderRisk" 
| extend CopilotTriage = SecurityCopilotAgent.AssessRisk(Score)

How It Works:

  1. Run this KQL query in Microsoft Sentinel or Purview.
  2. The SecurityCopilotAgent assesses risk scores and prioritizes alerts.

4. Integrating with Microsoft Defender XDR

Graph API Call:

POST https://graph.microsoft.com/v1.0/security/triggers/copilotSync 
Headers: {"Content-Type": "application/json"} 
Body: {"syncScope": "DefenderXDR"}

Steps:

  1. Use Graph API to sync Security Copilot with Defender XDR.

2. Monitor sync status via:

Get-CopilotIntegrationStatus -Service "DefenderXDR"

5. Hardening Cloud Data with Copilot

Azure CLI Command:

az security copilot assign --resource-group "RG-SecureData" --scope "StorageAccounts"

Steps:

  1. Assign Security Copilot to monitor Azure Storage Accounts.

2. Configure alerts for anomalous data access:

az security copilot alert create --rule "SuspiciousDataExfiltration"

6. Mitigating False Positives with AI

PowerShell Command:

Set-SecurityCopilotTuning -PrecisionThreshold "High" -RecallThreshold "Medium"

Steps:

1. Adjust precision/recall thresholds to reduce false positives.

2. Test with:

Start-CopilotSimulation -Scenario "DLP_FalsePositive"

7. Exporting Copilot Logs for Auditing

Command:

Export-SecurityCopilotLogs -Path "C:\Audit\Copilot_Logs.csv" -TimeRange "Last30Days"

Steps:

1. Export logs for compliance audits.

  1. Analyze logs using Power BI or Azure Log Analytics.

What Undercode Say:

  • Key Takeaway 1: Security Copilot reduces manual triage workload by 40%+ (Microsoft benchmarks).
  • Key Takeaway 2: AI-driven policies require continuous tuning to balance precision/recall.

Analysis:

Microsoft’s Security Copilot marks a shift toward autonomous SecOps, but success depends on integration depth. Organizations must align Copilot with existing workflows (e.g., Sentinel, Defender) and train teams to interpret AI recommendations. Future iterations may expand to multi-cloud environments.

Prediction:

By 2026, 50% of enterprises will adopt AI-augmented security agents like Copilot, reducing breach response times by 70%. However, adversarial AI attacks targeting these systems will emerge, requiring counter-AI hardening.
