feat: Add Microsoft Sentinel accelerator with UEBA, analytics, and data connectors (#1280) by sedmonds22 · Pull Request #1281 · Azure/missionlz

sedmonds22 · 2026-02-26T15:40:09Z

Summary

Adds optional Microsoft Sentinel integration to Mission Landing Zone that provisions security monitoring infrastructure alongside the core MLZ deployment, reducing manual post-deployment configuration and accelerating time-to-security-value.

Closes #1280

Changes

Core Sentinel Infrastructure

Sentinel Enablement - Deploy Microsoft Sentinel solution on the Operations Log Analytics workspace with configurable opt-in parameters
Entity Behavior Analytics (UEBA) - Configure entity sync and behavioral analytics for advanced threat detection
UEBA Data Sources - Connect SigninLogs, AuditLogs, and AzureActivity to feed user/entity behavioral insights
Anomaly Detection - Enable built-in Sentinel anomaly rules

Data Connectors

Microsoft Entra ID - SignInLogs, AuditLogs, NonInteractiveUserSignInLogs, ServicePrincipalSignInLogs, ManagedIdentitySignInLogs, ProvisioningLogs, ADFSSignInLogs, UserRiskEvents, RiskyUsers, RiskyServicePrincipals, and alerts
Azure Activity - Subscription-level Azure resource operations and administrative events

Security Content

90+ Analytic Rules - Pre-configured detection rules for identity threats, Azure infrastructure monitoring, Conditional Access changes, and more
4 Workbooks - Azure Activity, Entra ID Audit Logs, Entra ID Sign-ins, and Azure Service Health visualization dashboards
Content Packages - Azure Activity and Microsoft Entra ID solution packages

New Bicep Modules

\sentinel-settings.bicep\ - UEBA, entity behavior, and anomaly configuration
\sentinel-connectors.bicep\ - Data connector deployment (Entra ID, Azure Activity)
\sentinel-content.bicep\ - Content package deployment
\sentinel-analytic-rules.bicep\ - Analytic rule deployment from manifest
\sentinel-workbooks.bicep\ / \sentinel-workbooks-rg.bicep\ - Workbook deployment

New Parameters

Parameter	Default	Description
\deploySentinel\	\alse\	Enable Microsoft Sentinel deployment
\deploySentinelDataConnectors\	\alse\	Deploy Entra ID and Azure Activity connectors
\deploySentinelContent\	\alse\	Deploy analytic rules and workbooks

Backward Compatibility

All Sentinel features are opt-in with parameters defaulting to \alse. Existing MLZ deployments are unaffected when Sentinel parameters are not specified.

Testing

Bicep validation passes (\�z bicep build)
Deployment tested with Sentinel enabled
Deployment tested with Sentinel disabled (backward compatibility)
Analytic rules deploy successfully
Data connectors configure correctly
Workbooks render properly

…tent (#1280) - Add Sentinel settings, connectors, content, workbooks, and analytic rules modules - Support Azure Activity and Entra ID data connectors - Include Content Hub solutions and workbook templates - Add comprehensive Sentinel parameters to mlz.bicep Closes #1280

…, Hardcoded sentinel settings

Copilot

Pull request overview

Adds an opt-in Microsoft Sentinel “accelerator” layer to Mission Landing Zone (MLZ), intended to provision Sentinel settings (UEBA/anomalies), data connectors, analytic rules, and workbooks on top of the Operations Log Analytics workspace during deployment.

Changes:

Introduces new Sentinel-focused Bicep modules to configure Sentinel settings, data connectors, content packages, analytic rules, and workbooks.
Wires a new modules/sentinel.bicep deployment into src/mlz.bicep behind the existing deploySentinel flag.
Adds a large set of Sentinel analytic rule definitions plus a generated manifest used by a deployment script.
