To quickly secure a Microsoft 365/Entra tenant, follow these five steps:
- Sign in as admin at setup.cloud.microsoft.
- Navigate to All guides → Deploy CA policies.
3. Select the Zero Trust category.
4. Select all policies and deploy.
5. Enable policies after verifying in report-only mode.
This deploys 14 Conditional Access (CA) policies to enforce Zero Trust principles.

You Should Know:
1. Verify Conditional Access Policies via PowerShell
Use Microsoft Graph PowerShell to check deployed policies:
Connect-MgGraph -Scopes "Policy.Read.All" Get-MgIdentityConditionalAccessPolicy | Select-Object DisplayName, State
2. Enable Policies in Bulk
To enable all report-only policies:
$policies = Get-MgIdentityConditionalAccessPolicy -Filter "state eq 'disabled'"
foreach ($policy in $policies) {
Update-MgIdentityConditionalAccessPolicy -ConditionalAccessPolicyId $policy.Id -State "enabled"
}
3. Monitor CA Policy Impact
Check Azure AD sign-in logs for policy effects:
Get-MgAuditLogSignIn -Filter "conditionalAccessStatus eq 'success'" -Top 100
4. Break Glass Account Setup
Exclude emergency accounts from CA policies:
New-MgUser -DisplayName "BreakGlassAdmin" -UserPrincipalName "[email protected]" -PasswordProfile @{ForceChangePasswordNextSignIn=$false}
5. Enforce FIDO2 for Break Glass
Require hardware keys for emergency access:
Set-MgUserAuthenticationMethod -UserId "[email protected]" -MethodType "fido2"
6. Enable Logging for Break Glass Usage
Set up Azure Monitor alerts:
New-AzAlertRule -Name "BreakGlassAccessAlert" -Location "Global" -ResourceGroup "Security" -Condition "AzureActivity | where OperationName == 'Sign-in activity' and Identity contains '[email protected]'" -ActionGroup "/subscriptions/xxx/resourceGroups/yyy/providers/microsoft.insights/actionGroups/zzz"
What Undercode Say:
Securing Microsoft 365/Entra requires automation, monitoring, and strict access controls. The Zero Trust policies deployed via `setup.cloud.microsoft` provide a strong baseline, but manual verification via PowerShell and Azure AD logs is crucial.
- Always exclude break-glass accounts from Conditional Access.
- Enforce FIDO2 keys for emergency logins.
- Monitor sign-ins for anomalies.
- Leverage Microsoft Graph API for policy automation.
For deeper security, integrate Microsoft Sentinel for SIEM capabilities:
New-AzSentinelAlertRule -WorkspaceName "SecOps" -DisplayName "CA Policy Bypass Attempt" -Query "SigninLogs | where ConditionalAccessPolicies !has 'Success'" -Severity "High"
Prediction:
Microsoft will expand default Zero Trust deployments with AI-driven policy recommendations, reducing manual configuration. Expect more automated compliance enforcement in Entra ID.
Expected Output:
- Deployed 14 CA policies in report-only mode.
- Verified policies via PowerShell & Azure AD logs.
- Secured break-glass accounts with FIDO2.
- Enabled real-time monitoring for emergency access.
