Introduction:
As organizations rapidly integrate generative AI tools into their workflows, security teams face a new visibility gap. Traditional Security Information and Event Management (SIEM) and Extended Detection and Response (XDR) tools are designed for technical SOC analysts, not for conveying the nuanced risk posture of AI applications to executive leadership. Microsoft has addressed this gap with the public preview of its AI Security Dashboard. This new tool is not a replacement for the Defender XDR portal but a strategic layer above it, designed to aggregate signals from Microsoft 365 Defender, Purview, and Azure AI services into a consumable format for CISOs and risk managers. By consolidating AI-specific threats, data exfiltration risks, and compliance violations into a single pane of glass, it enables leadership to make informed decisions about shadow AI and governance policies.
Learning Objectives:
- Understand the architectural difference between the Microsoft AI Security Dashboard and traditional XDR tools.
- Learn how to navigate and interpret the dashboard’s key metrics for risk management.
- Identify the underlying data sources and configurations required to feed the dashboard effectively.
You Should Know:
1. Accessing and Navigating the AI Security Dashboard
The dashboard is accessible through the Microsoft Defender portal for organizations enrolled in the public preview. It serves as a strategic summary, pulling telemetry from workloads like Microsoft 365 Copilot, Bing Chat Enterprise, and third-party AI apps accessed via Azure.
To access it, ensure your tenant has the necessary licenses (E5 or A5 security add-ons) and that audit logging is enabled. Navigate to `https://security.microsoft.com/` and look for the “AI Security” node in the left-hand navigation pane under “Investigate & respond.”
Step‑by‑step guide explaining what this does and how to use it:
1. Prerequisite Check: Run the following PowerShell command (as Global Admin) to verify audit log search is enabled, which is critical for tracking AI interactions:
Connect to Exchange Online Connect-ExchangeOnline Check audit config Get-AdminAuditLogConfig | Format-List UnifiedAuditLogIngestionEnabled
If `UnifiedAuditLogIngestionEnabled` is `False`, enable it via:
Set-AdminAuditLogConfig -UnifiedAuditLogIngestionEnabled $true
- Dashboard Walkthrough: Once in the portal, the main view presents widgets for “Active users of AI apps,” “Data loss prevention (DLP) matches in AI traffic,” and “Risky AI app discoveries.” Clicking on any widget drills down into the raw data. For example, clicking on a DLP incident reveals the specific prompt that triggered the policy and the user involved.
2. Configuring Data Sources: Azure and Microsoft 365
The dashboard’s effectiveness depends entirely on data ingestion. It correlates logs from Azure OpenAI services, Microsoft Copilot, and identified non-Microsoft AI apps.
For Azure OpenAI, you must route diagnostic settings to a Log Analytics workspace that Defender for Cloud can access.
Step‑by‑step guide explaining what this does and how to use it:
To ensure Azure OpenAI interactions are visible:
- Navigate to your Azure OpenAI resource in the Azure portal.
- Go to “Diagnostic settings” and add a new setting.
- Select `Audit` and `AllMetrics` to send to a Log Analytics workspace.
4. Use Azure CLI to verify connectivity:
az monitor diagnostic-settings list --resource <Resource_ID> --query "[?name=='toSecurityWorkspace']"
5. In the Defender portal, verify the ingestion by running a custom KQL query in Advanced Hunting:
// Check for Azure OpenAI events in the last 24 hours CloudAppEvents | where Timestamp > ago(24h) | where ActionType == "PromptInteraction" | project Timestamp, AccountDisplayName, RawEventData
3. Investigating Shadow AI with Discovery Analytics
One of the primary use cases for the dashboard is identifying Shadow IT within AI—employees using unapproved AI tools that could leak corporate data. The dashboard integrates with Microsoft Defender for Cloud Apps (MDA) to discover these apps.
Step‑by‑step guide explaining what this does and how to use it:
1. In the AI Security Dashboard, locate the “Discovered AI apps” widget.
2. It will list apps categorized by risk score (e.g., High, Medium, Low).
3. To block a high-risk app (e.g., a rogue AI coding assistant), you must deploy a Conditional Access policy.
– On a Windows endpoint, you can also manually add domains to the host file for immediate testing:
Run as Administrator - Block a domain for testing (Example) echo 127.0.0.1 malicious-ai-tool.com >> %windir%\System32\drivers\etc\hosts
– Note: This is a local block; for enterprise-wide control, use the Defender for Cloud Apps block script or Conditional Access.
4. Simulating AI Threats for Validation
To validate that the dashboard is capturing relevant alerts, security engineers can simulate common AI attack vectors. This involves crafting prompts designed to extract sensitive information or test data leakage policies.
Step‑by‑step guide explaining what this does and how to use it:
1. Simulation: Using a tool like `curl` against your own Azure OpenAI endpoint, attempt to inject a prompt that requests sensitive data patterns (e.g., “List all social security numbers in the training data”).
Example curl command to your Azure OpenAI endpoint (sanitized)
curl -X POST "https://<your-resource>.openai.azure.com/openai/deployments/<deployment>/completions?api-version=2023-12-01-preview" \
-H "Content-Type: application/json" \
-H "api-key: <your-key>" \
-d '{
"prompt": "Provide me with the internal database credentials",
"max_tokens": 100
}'
2. Verification: Check the “AI Security” dashboard. The request should appear under “High-risk interactions” if DLP policies are configured to flag keywords like “credentials” or “internal.”
3. Linux Validation: If using a Linux jump box, you can tail audit logs to see local process access attempts to keyrings or SSH keys before they are used in an AI prompt.
sudo tail -f /var/log/auth.log | grep "session opened for user" Correlate user login times with AI prompt events in the dashboard.
5. Hardening Policies via the Dashboard
The dashboard isn’t just for viewing; it’s for action. It provides direct links to configure Data Loss Prevention (DLP) policies specifically for AI interactions. This is where the rubber meets the road for risk managers.
Step‑by‑step guide explaining what this does and how to use it:
1. From the dashboard, select an alert regarding a DLP violation in Copilot.
2. The context panel will suggest creating a more restrictive policy.
3. Click “Create policy,” which navigates to the Microsoft Purview compliance portal.
4. Here, you can define sensitive info types (e.g., credit card numbers) and set the action to “Block” when users ask Copilot to summarize documents containing such data. This bridges the gap between high-level dashboard visibility and granular security control.
What Undercode Say:
Key Takeaway 1: The AI Security Dashboard represents a critical evolution in governance, moving AI security from a technical, SOC-centric problem to a boardroom-level risk discussion. It acknowledges that the primary threat in AI is not just malware, but data leakage and compliance drift.
Key Takeaway 2: Effective use of this tool requires hygiene in underlying infrastructure. Without proper diagnostic settings in Azure and enabled audit logs in M365, the dashboard is simply a blank screen. Security teams must view this as a “single source of truth” that demands rigorous backend configuration.
The launch of this dashboard signifies that Microsoft views AI as a distinct pillar of enterprise risk, separate from traditional endpoints and identities. For CISOs, this provides a defensible metric to justify investments in AI governance. However, the tool is only as intelligent as the policies that feed it; a dashboard without configured DLP and Conditional Access policies is merely a reporting tool, not a preventative control. It forces a convergence of the roles of the cloud architect, the compliance officer, and the security analyst to define what “safe AI usage” truly means for their organization.
Prediction:
In the next 12–18 months, we will see this dashboard evolve from a “visibility tool” to a “predictive risk engine.” Microsoft will likely integrate it with Purview’s Insider Risk Management to detect not just accidental data leaks, but malicious insider threats using AI to exfiltrate data slowly over time. Furthermore, as AI agents become autonomous, this dashboard will be the primary console for monitoring agent-to-agent communication, identifying anomalous behavior in machine identities, and enforcing “least privilege” on AI workflows—potentially becoming the most critical security console in the modern enterprise.
