Microsoft has introduced the Microsoft Entra Conditional Access optimization agent in preview, designed to strengthen security by ensuring all users are protected under optimal policies. This agent evaluates and recommends policy adjustments based on Zero Trust principles and Microsoft’s security insights.
Key Features:
- Multi-Factor Authentication (MFA) Enforcement: Recommends policies to enforce MFA where necessary.
- Device-Based Controls: Evaluates device compliance, app protection policies, and domain-joined devices.
- Legacy Authentication Blocking: Identifies and blocks outdated authentication methods.
- Policy Consolidation: Analyzes existing policies to suggest merging similar ones for better efficiency.
Learn more in the official documentation: Microsoft Entra Conditional Access Optimization Agent.
You Should Know:
1. Enforcing MFA via PowerShell
To enable MFA for users in Azure AD, use:
Connect-MgGraph -Scopes "Policy.ReadWrite.ConditionalAccess"
New-MgIdentityConditionalAccessPolicy -DisplayName "Require MFA for All Users" -State "enabled" -Conditions @{
Applications = @{IncludeApplications = "All"}
Users = @{IncludeUsers = "All"}
ClientAppTypes = @("Browser", "MobileAppsAndDesktopClients")
} -GrantControls @{
BuiltInControls = @("mfa")
Operator = "OR"
}
2. Blocking Legacy Authentication
Legacy protocols (e.g., IMAP, SMTP) are vulnerable. Block them using:
New-MgIdentityConditionalAccessPolicy -DisplayName "Block Legacy Auth" -State "enabled" -Conditions @{
ClientAppTypes = @("ExchangeActiveSync", "Other")
Applications = @{IncludeApplications = "All"}
} -GrantControls @{
BuiltInControls = @("Block")
}
3. Checking Device Compliance in Intune
Verify device compliance status with:
Get-MgDeviceManagementManagedDevice -Filter "complianceState eq 'compliant'"
4. Auditing Conditional Access Policies
List all existing policies:
Get-MgIdentityConditionalAccessPolicy | Select-Object DisplayName, State, Conditions
5. Linux Command for Monitoring Azure AD Sign-Ins
Use `curl` to check risky sign-ins via Microsoft Graph API:
curl -s -H "Authorization: Bearer $(az account get-access-token --query accessToken -o tsv)" \ "https://graph.microsoft.com/v1.0/identityProtection/riskDetections" | jq '.value[] | select(.riskLevel == "high")'
What Undercode Say:
The Microsoft Entra Conditional Access optimization agent is a critical step toward automated Zero Trust policy enforcement. Key takeaways:
– MFA is non-negotiable—enforce it via PowerShell or Azure Portal.
– Legacy auth must be blocked—attackers exploit outdated protocols.
– Device compliance checks ensure only trusted devices access resources.
– Policy consolidation reduces complexity and misconfigurations.
For deeper security, integrate with Microsoft Defender for Identity and Azure Sentinel for real-time threat detection.
Expected Output:
A hardened Azure AD environment with:
✔ MFA enforced globally.
✔ Legacy authentication disabled.
✔ Compliant-only device access.
✔ Consolidated Conditional Access policies.
