Auditing Microsoft Entra ID (Azure Active Directory) configuration to identify risky authentication policies, overly permissive role assignments, stale accounts, conditional access gaps, and guest user risks using AzureAD PowerShell, Microsoft Graph API, and ScoutSuite.
When performing a security assessment of an Azure tenant's identity configuration
When compliance audits require review of authentication policies, MFA enforcement, and role assignments
When onboarding a new Azure tenant after merger or acquisition
When investigating suspicious sign-in activity or compromised accounts
When validating conditional access policies adequately protect against identity-based attacks
Do not use for on-premises Active Directory auditing (use PingCastle or BloodHound AD), for Azure resource-level RBAC auditing without identity context, or for real-time threat detection (use Microsoft Defender for Identity).
Prerequisites
Global Reader or Security Reader role in the target Microsoft Entra ID tenant
Microsoft Graph PowerShell SDK installed (Install-Module Microsoft.Graph)
Az CLI authenticated to the target tenant (az login --tenant TENANT_ID)
ScoutSuite with Azure provider configured for automated assessment
Access to Azure AD audit logs and sign-in logs (requires Azure AD Premium P1/P2)
Workflow
Step 1: Enumerate Tenant Configuration and Security Defaults
Assess the tenant's baseline identity security settings including security defaults and legacy authentication status.
# Connect to Microsoft Graph
Connect-MgGraph -Scopes "Directory.Read.All","Policy.Read.All","AuditLog.Read.All"
# Get tenant details
Get-MgOrganization | Select-Object DisplayName, Id, VerifiedDomains
# Check if Security Defaults are enabled
Get-MgPolicyIdentitySecurityDefaultEnforcementPolicy | Select-Object IsEnabled
# List authentication methods policies
Get-MgPolicyAuthenticationMethodPolicy | ConvertTo-Json -Depth 5
# Check legacy authentication status via Conditional Access
Get-MgIdentityConditionalAccessPolicy | Where-Object {
$_.Conditions.ClientAppTypes -contains "exchangeActiveSync" -or
$_.Conditions.ClientAppTypes -contains "other"
} | Select-Object DisplayName, State
Step 2: Audit Privileged Role Assignments
Review directory role assignments to identify over-privileged users, permanent admin accounts, and risky role configurations.
# List all Global Administrator assignments
az rest --method GET \
--url "https://graph.microsoft.com/v1.0/directoryRoles/filterByIds" \
--body '{"ids":["62e90394-69f5-4237-9190-012177145e10"]}' | \
az rest --method GET \
--url "https://graph.microsoft.com/v1.0/directoryRoles?filter=displayName eq 'Global Administrator'" \
--query -o tsv
az rest --method GET \
--url \
--query \
-o table
az ad user list --query -o table
az rest --method GET \
--url \
-o json
"value[0].id"
# List all privileged role assignments using Graph API
Find accounts that have not signed in recently, disabled accounts with active role assignments, and risky guest user configurations.
# Find users who haven't signed in for 90+ days
az ad user list --query "[?signInActivity.lastSignInDateTime < '2025-11-25T00:00:00Z'].{UPN:userPrincipalName, LastSignIn:signInActivity.lastSignInDateTime, Enabled:accountEnabled}" -o table
# List all guest users
az ad user list --filter "userType eq 'Guest'" \
--query "[].{UPN:userPrincipalName, DisplayName:displayName, CreatedDate:createdDateTime}" \
-o table
# Find guest users with privileged roles
az rest --method GET \
--url "https://graph.microsoft.com/v1.0/roleManagement/directory/roleAssignments?\$expand=principal" \
--query "value[?principal.userType=='Guest'].{Role:roleDefinitionId,Guest:principal.userPrincipalName}" \
-o table
# Check for accounts with disabled MFA
az rest --method GET \
--url "https://graph.microsoft.com/v1.0/reports/authenticationMethods/userRegistrationDetails" \
--query "value[?!isMfaRegistered].{UPN:userPrincipalName,MfaRegistered:isMfaRegistered}" \
-o table
Step 5: Analyze Sign-In Logs for Risky Activity
Review sign-in logs to identify anomalous authentication patterns, failed MFA challenges, and risky sign-in detections.
# Get risky sign-ins from last 7 days
az rest --method GET \
--url "https://graph.microsoft.com/v1.0/auditLogs/signIns?\$filter=riskLevelDuringSignIn ne 'none' and createdDateTime ge 2026-02-16T00:00:00Z" \
--query "value[*].{User:userPrincipalName,Risk:riskLevelDuringSignIn,IP:ipAddress,App:appDisplayName,Status:status.errorCode}" \
-o table
# Get sign-ins from unfamiliar locations
az rest --method GET \
--url "https://graph.microsoft.com/v1.0/auditLogs/signIns?\$filter=riskEventTypes_v2/any(r:r eq 'unfamiliarFeatures')" \
--query "value[*].{User:userPrincipalName,Location:location.city,IP:ipAddress}" \
-o table
# Check for legacy authentication sign-ins
az rest --method GET \
--url "https://graph.microsoft.com/v1.0/auditLogs/signIns?\$filter=clientAppUsed ne 'Browser' and clientAppUsed ne 'Mobile Apps and Desktop clients'" \
--query "value[*].{User:userPrincipalName,ClientApp:clientAppUsed,Status:status.errorCode}" \
-o table
Step 6: Run ScoutSuite Automated Assessment
Execute ScoutSuite for comprehensive automated checks across the Azure tenant configuration.
# Run ScoutSuite against Azure
python3 -m ScoutSuite azure --cli \
--report-dir ./scoutsuite-azure-report \
--all-subscriptions
# Review the generated HTML report
open ./scoutsuite-azure-report/azure-report.html
Key Concepts
Term
Definition
Microsoft Entra ID
Microsoft's cloud identity and access management service, formerly Azure Active Directory, providing authentication and authorization
Conditional Access
Policy engine that evaluates signals (user, device, location, risk) to enforce access controls like MFA, device compliance, or block access
Security Defaults
Microsoft's baseline identity protection settings that enforce MFA registration, block legacy auth, and protect privileged actions
Privileged Identity Management
Azure AD Premium P2 feature enabling just-in-time privileged access with approval workflows and time-bound role activation
Legacy Authentication
Older authentication protocols (POP3, IMAP, SMTP, ActiveSync) that do not support MFA and are commonly exploited for credential attacks
Risky Sign-In
Microsoft Entra Identity Protection detection of sign-in anomalies including impossible travel, unfamiliar locations, and malware-linked IPs
Tools & Systems
Microsoft Graph API: Primary programmatic interface for querying Entra ID configuration, policies, roles, and audit logs
Microsoft Graph PowerShell SDK: PowerShell module for Entra ID management and security auditing tasks
ScoutSuite: Multi-cloud auditing tool with Azure provider support for IAM, storage, networking, and identity checks
AzureADRecon: Community tool for comprehensive Azure AD reconnaissance and security assessment reporting
Microsoft Defender for Identity: Cloud-based security solution for detecting identity-based threats and compromised credentials
Context: After acquiring a company, the security team needs to assess the Azure tenant identity posture before integrating it with the corporate Entra ID.
Approach:
Enumerate all Global Administrators and check for personal accounts in admin roles
Review conditional access policies to verify MFA is enforced for all users, not just admins
Identify guest users with privileged access that may indicate third-party vendor over-permissioning
Check for stale accounts (no sign-in for 90+ days) that could be targets for credential attacks
Review sign-in logs for legacy authentication usage that bypasses MFA
Verify Security Defaults or equivalent CA policies block legacy auth protocols
Produce a risk report with prioritized remediation steps before tenant integration
Pitfalls: Azure AD Premium P2 is required for risky sign-in detections and PIM. If the acquired tenant uses a lower license tier, many identity protection features will be unavailable. Guest users from partner tenants may have implicit access through dynamic groups that are not visible in standard role assignment queries.
