  • Managing VMware with PowerCLI: Essential PowerShell Commands

    Introduction VMware PowerCLI is a powerful tool that allows administrators to manage VMware environments using PowerShell. Whether you need to create virtual machines, check resource usage, or troubleshoot storage capacity, PowerCLI provides a streamlined approach to VMware management. Below is a guide to setting up PowerCLI and using essential commands for day-to-day VMware administration.


    Step 1: Install and Import VMware PowerCLI

    Before running VMware-related PowerShell commands, ensure that VMware PowerCLI is installed on your system.

    Install-Module -Name VMware.PowerCLI -Scope CurrentUser -Force

    After installation, import the module:

    Import-Module VMware.PowerCLI

    If you encounter SSL/TLS certificate warnings while connecting, configure PowerCLI to ignore invalid certificates:

    Set-PowerCLIConfiguration -InvalidCertificateAction Ignore -Confirm:$false

    Step 2: Connect to vCenter Server

    To manage your VMware environment, you need to authenticate with vCenter:

    Connect-VIServer -Server <Your-VCenter-Server> -User <Your-Admin-User> -Password '<Your-Password>'

    Once connected, you can retrieve information about your virtual infrastructure.


    Step 3: List VMware Hosts

    To view all available VMware hosts:

    Get-VMHost

    This provides a list of all ESXi hosts, their connection status, and available resources.


    Step 4: Retrieve Virtual Machines

    To get a list of all VMs in the environment:

    Get-VM

    For details of a specific VM:

    Get-VM -Name <VM-Name>

    Step 5: Checking vSAN Datastore Usage

    One common challenge in VMware environments is monitoring vSAN datastore usage. To check storage space:

    Get-VsanSpaceUsage -Cluster <Your-Cluster-Name>

    To calculate the percentage of used space, run:

    $vsanUsage = Get-VsanSpaceUsage -Cluster <Your-Cluster-Name>
    $usedPercentage = 100 - (($vsanUsage.FreeSpaceGB / $vsanUsage.CapacityGB) * 100)
    "vSAN Datastore is currently {0:N2}% full" -f $usedPercentage

    Step 6: Creating a New Virtual Machine

    If you need to create a new VM:

    New-VM -Name <VM-Name> -VMHost <Host-Name> -Datastore <Datastore-Name> -DiskGB 50 -MemoryGB 4 -NumCPU 2

    This command creates a VM with 50GB disk, 4GB RAM, and 2 CPUs.


    Step 7: Cloning an Existing Virtual Machine

    To create a clone of an existing VM:

    New-VM -Name <New-VM-Name> -VM <Source-VM-Name> -Datastore <Datastore-Name> -VMHost <Target-Host>

    Step 8: Managing VM Power States

    To power on a VM:

    Start-VM -VM <VM-Name>

    To shut down a VM:

    Stop-VM -VM <VM-Name> -Confirm:$false

    To restart a VM:

    Restart-VM -VM <VM-Name> -Confirm:$false

    Step 9: Deleting a Virtual Machine

    If a VM is no longer needed, you can remove it permanently:

    Remove-VM -VM <VM-Name> -DeletePermanently -Confirm:$false

    Step 10: Checking for Leftover Files in vSAN

    Even after deleting a VM, some files may remain in the datastore. You can check for orphaned files:

    Get-Datastore -Name <Datastore-Name> | Get-ChildItem -Recurse | Where-Object { $_.Name -like "*<VM-Name>*" }

    To manually remove leftover files:

    Remove-Item -Path "vmstore:\<Datastore-Name>\FolderName\<VM-Name>.vmdk" -Confirm:$false

    Final Thoughts

    Using PowerCLI to manage VMware environments improves efficiency and automation. Whether you need to monitor vSAN usage, create new VMs, or automate backups, PowerCLI provides a flexible solution. Keep this guide handy for reference as you work with VMware environments.

  • How to Investigate and Secure a Compromised Microsoft 365 Account After a Phishing Attack

    Introduction

    Phishing attacks are one of the most common cybersecurity threats that IT administrators face. A single click on a malicious email link can lead to credential theft, data exfiltration, or malware infections.

    This guide provides a step-by-step approach to investigating and securing a potentially compromised account in Microsoft 365 using PowerShell and the Microsoft Security Portal.


    🔹 Immediate Response: Disconnect & Secure the Affected Computer

    Before investigating, act fast to prevent further damage:

    1️⃣ Shut down the compromised computer immediately.
    2️⃣ Disconnect from the network (unplug Ethernet, disable Wi-Fi).
    3️⃣ Reset the password for the affected user.
    4️⃣ Revoke all active sessions to log out any potential attacker.

    PowerShell Command to Revoke Sessions:

    powershellCopyEditRevoke-AzureADUserAllRefreshToken -ObjectId "[email protected]"
    

    Reset MFA to Prevent Unauthorized Re-Login:

    powershellCopyEditReset-MsolStrongAuthenticationMethodByUpn -UserPrincipalName "[email protected]"
    

    🔹 Step 1: Check for Unauthorized Sign-ins in Azure AD

    Use Azure AD Sign-in Logs to check for suspicious login attempts.

    PowerShell Command to Retrieve Sign-in Logs:

    powershellCopyEditConnect-AzureAD
    Get-AzureADAuditSignInLogs -Filter "status/errorCode ne '0'"
    

    Alternative:

    🔍 Red Flags:

    🚩 Logins from unexpected locations or devices
    🚩 Multiple failed MFA attempts
    🚩 Impossible travel scenarios (e.g., two logins from different continents within minutes)


    🔹 Step 2: Investigate Phishing Emails Across the Organization

    If an attacker sent phishing emails to multiple employees, run a Compliance Search to identify all affected mailboxes.

    PowerShell Command to Search All Mailboxes for Suspicious Emails:

    powershellCopyEditNew-ComplianceSearch -Name "CompanyPhishingScan" -ExchangeLocation All -ContentMatchQuery 'has:attachment OR has:link'
    Start-ComplianceSearch -Identity "CompanyPhishingScan"
    

    Check Results:

    powershellCopyEditGet-ComplianceSearch -Name "CompanyPhishingScan" | Select Name, Status, Items
    

    If Phishing Emails Are Found, Remove Them:

    powershellCopyEditNew-ComplianceSearchAction -SearchName "CompanyPhishingScan" -Purge -PurgeType SoftDelete
    

    🚨 Use HardDelete only if emails must be permanently removed.


    🔹 Step 3: Check & Remove Hidden Forwarding Rules

    Attackers often set up automatic forwarding to steal emails.

    Check for Forwarding Rules:

    powershellCopyEditGet-Mailbox -Identity "[email protected]" | Select ForwardingAddress, ForwardingSmtpAddress
    

    Disable Auto-Forwarding if Found:

    powershellCopyEditSet-Mailbox -Identity "[email protected]" -ForwardingAddress $null -ForwardingSmtpAddress $null
    

    🔹 Step 4: Scan the Compromised Computer Before Reconnecting

    Since a phishing link was clicked, scan the system for malware before reconnecting to the network.

    Offline Windows Defender Scan:

    powershellCopyEditStart-MpScan -ScanType FullScan
    

    If Threats Are Found, Remove Them:

    powershellCopyEditRemove-MpThreat -AllThreats
    

    For a Deep Rootkit Scan, Use Windows Defender Offline:

    powershellCopyEditStart-MpWDOScan
    

    ✅ This will restart the system and scan before Windows boots.


    🔹 Step 5: Implement Long-Term Protection Measures

    Enable Safe Links & Safe Attachments in Microsoft Defender

    • Safe Links: Blocks phishing links before users click them.
    • Safe Attachments: Scans email attachments for malware before delivery.

    Enable Safe Links Policy:

    powershellCopyEditSet-SafeLinksPolicy -Identity "Default" -EnableSafeLinks $true -TrackClicks $true
    

    Enable Safe Attachments Policy:

    powershellCopyEditSet-MalwareFilterPolicy -Identity "Default" -EnableSafeAttachmentsForMail $true
    

    ✅ Educate Users on Phishing Awareness

    🔹 Enable the “Report Message” button in Outlook so employees can easily flag suspicious emails.
    🔹 Train employees to recognize phishing emails:
    ✔ Unexpected links
    ✔ Urgent language
    ✔ Sender impersonation


    🚀 Final Wrap-Up: Is the Account and System Secure?

    Account fully secured: No unauthorized logins, MFA reset, all active sessions revoked.
    Email threats removed: No phishing emails remain in any mailbox.
    PC scanned and clean: No malware detected before reconnecting.
    Long-term protections enabled: Safe Links, Safe Attachments, user education.

    By following these steps, IT admins can quickly contain and prevent phishing incidents in Microsoft 365! 🚀

    Conditional Access Support – Controls access based on risk level

    💡 Common Use Cases

    🔹 Access legacy web apps from any device
    🔹 Provide secure extranet access for partners
    🔹 Replace traditional VPNs for application access
    🔹 Enable remote access to intranet apps


    🔹 How Does Azure App Proxy Work?

    Azure App Proxy consists of two main components:

    1. Application Proxy Service (Cloud-based)
      • Runs in Azure
      • Authenticates users via Entra ID
      • Sends requests to the on-premises connector
    2. Application Proxy Connector (On-Premises Agent)
      • Installed inside the corporate network
      • Forwards authenticated requests to internal applications
      • Uses outbound traffic only (no firewall holes needed)

    📌 Architecture Flow

    1️⃣ User accesses app-protected URL
    2️⃣ Azure App Proxy authenticates the user via Entra ID
    3️⃣ Request is forwarded to the on-premises App Proxy Connector
    4️⃣ Connector retrieves the response & sends it back via Azure Proxy


    🔹 Prerequisites

    Before deploying Azure App Proxy, ensure:
    Microsoft Entra ID (Azure AD) P1 or P2 license
    An on-premises Windows Server (2016+) to install the connector
    Outbound internet access on the connector server
    Domain-joined or cloud-hybrid environment (if using SSO)
    App must use HTTP/HTTPS (No TCP/UDP apps)


    🛠️ Deploying Azure App Proxy

    🔹 Step 1: Install Application Proxy Connector

    📌 Run the following PowerShell command on your Windows Server:

    powershellCopyEditInvoke-WebRequest -Uri https://aka.ms/aadappproxy -OutFile "AADAppProxyInstaller.exe"
    Start-Process "AADAppProxyInstaller.exe" -ArgumentList "/quiet" -Wait
    

    👉 Sign in with Global Admin credentials to register the connector.

    Verify that the connector is running:

    powershellCopyEditGet-Service | Where-Object { $_.DisplayName -match "Application Proxy Connector" }
    

    🔹 Step 2: Register the Application in Azure

    1️⃣ Sign into the Azure Portal
    2️⃣ Go to Microsoft Entra IDEnterprise Applications
    3️⃣ Click New ApplicationOn-premises Application
    4️⃣ Set External URL (e.g., https://app.jetmariano.us)
    5️⃣ Set Internal URL (e.g., http://internal-app-server.local)
    6️⃣ Choose Pre-authentication method:
    Azure AD (Recommended) – Uses SSO & Conditional Access
    Passthrough – No authentication (use only if required)


    🔹 Step 3: Configure Single Sign-On (SSO) (Optional)

    If using SSO with Kerberos, configure:

    powershellCopyEditSet-WebApplicationProxyApplication -Name "InternalApp" -BackendApplicationUrl "http://internal-app.local" -ExternalApplicationUrl "https://app.jetmariano.us" -ConnectorGroupID "ConnectorGroup1" -SSOType "KerberosConstrainedDelegation"
    

    ✅ This allows seamless authentication without repeated login prompts.


    🔹 Step 4: Test & Secure the Application

    🔹 Access your external URL and verify that it works.
    🔹 Enable Conditional Access for added security.
    🔹 Restrict access based on device compliance, location, MFA, etc.


    🔒 Best Practices for Azure App Proxy

    Use Azure AD Pre-authentication – Avoid exposing internal apps
    Enable Conditional Access – Enforce MFA & compliance policies
    Monitor access logs – Track login attempts & potential threats
    Use HTTPS for internal apps – Encrypt traffic end-to-end
    Scale with multiple connectors – Ensure redundancy & load balancing

  • Fixing MFA Lockout Issues & Bypass Methods in Azure AD

    Introduction

    Multi-Factor Authentication (MFA) is a crucial security measure in Microsoft Entra ID (formerly Azure AD) to protect against unauthorized access. However, users and administrators often encounter MFA lockout issues, preventing legitimate users from accessing their accounts. This can be due to device loss, incorrect configurations, or a lack of backup authentication methods.

    In this blog, we will cover: ✅ Why MFA lockout happens
    ✅ How to reset MFA for users
    ✅ Bypass methods for emergency access
    ✅ Best practices to prevent future issues


    🔍 Why Does MFA Lockout Happen?

    MFA lockouts typically occur due to:

    • Device Change – User loses access to their phone or resets their device
    • Authenticator App Issues – User gets a new phone and doesn’t migrate the Authenticator app
    • Phone Number Change – SMS authentication fails due to a new phone number
    • Policy Restrictions – Conditional Access or legacy MFA settings prevent login
    • MFA Throttling – Too many failed attempts lock out the user

    🛠️ How to Reset MFA for a User

    If a user is locked out, an Azure AD admin can reset their MFA settings. Here’s how:

    🔹 Reset MFA via Microsoft Entra Admin Center

    1. Sign in to Microsoft Entra Admin Center as an administrator.
    2. Navigate to Users > All users
    3. Search for the affected user and select them
    4. Click Authentication methods > Require Re-register MFA
    5. Have the user sign in again and set up MFA from scratch

    🔹 Reset MFA Using PowerShell

    Admins can reset MFA via PowerShell with Microsoft Graph PowerShell.

    1️⃣ Connect to Microsoft Graph

    powershellCopyEditConnect-MgGraph -Scopes "User.ReadWrite.All"
    

    2️⃣ Find the user needing an MFA reset

    powershellCopyEditGet-MgUser -UserId [email protected] | Select-Object DisplayName,UserPrincipalName,Id
    

    3️⃣ Reset MFA settings for the user

    powershellCopyEditRevoke-MgUserAuthenticationMethod -UserId [email protected]
    

    4️⃣ Confirm the user is cleared of previous MFA methods

    powershellCopyEditGet-MgUserAuthenticationMethod -UserId [email protected]
    

    The user will now be prompted to re-enroll in MFA at their next login.


    🚨 Emergency MFA Bypass Methods

    In cases where users are locked out and immediate access is required, temporary workarounds can help.

    1️⃣ Use a Temporary Access Pass (TAP)

    A Temporary Access Pass (TAP) allows a user to log in without MFA for a limited time.

    Enable TAP:

    1. Go to Microsoft Entra Admin Center
    2. Navigate to Users > Authentication Methods
    3. Enable Temporary Access Pass policy

    Issue a TAP for the user:

    powershellCopyEditNew-MgUserAuthenticationTemporaryAccessPassMethod -UserId [email protected] -LifetimeInMinutes 30 -IsUsableOnce $true
    

    The user can now sign in using the TAP and reset their MFA.


    2️⃣ Add a Backup Authentication Method

    If a user still has access to another sign-in method, add an additional MFA option.

    Via Admin Portal:

    1. Go to Users in Entra Admin Center
    2. Select the user > Authentication methods
    3. Click Add method and enter an alternate phone number or security key

    Via PowerShell:

    powershellCopyEditNew-MgUserAuthenticationPhoneMethod -UserId [email protected] -PhoneNumber "+1234567890" -PhoneType Mobile -SmsSignInState Enabled
    

    Now, the user can verify via SMS instead.


    3️⃣ Disable MFA Temporarily

    Warning: This is a security risk and should only be used as a last resort.

    Disable MFA for a user via PowerShell

    powershellCopyEditSet-MsolUser -UserPrincipalName [email protected] -StrongAuthenticationRequirements @()
    

    OR disable MFA for an entire tenant (not recommended):

    powershellCopyEditSet-MsolCompanySettings -PreventPerUserMFA $true
    

    Re-enable MFA as soon as possible.


    ✅ Best Practices to Prevent MFA Lockouts

    🔹 Enable Multiple Authentication Methods – Users should register both phone and Authenticator app.
    🔹 Use Temporary Access Passes (TAP) – Helps in cases of device loss.
    🔹 Educate Users on MFA Backup Codes – Encourage users to save backup codes.
    🔹 Enable Admin Recovery Options – Allow trusted admins to reset MFA.
    🔹 Monitor MFA Logs – Use Azure Sign-In Logs to track MFA failures:

    powershellCopyEditGet-MgAuditLogSignIn -Filter "status/errorCode eq 500121"
    

    📌 Conclusion

    MFA is essential for securing accounts, but lockouts can frustrate users and disrupt productivity. By using TAP, PowerShell resets, and backup methods, admins can quickly restore access while keeping security intact.

    🚀 What’s next? Consider automating MFA resets with Microsoft Graph API or setting up self-service MFA reset policies for users.

  • Azure Single Sign-On (SSO): What It Is and How to Implement It

    Introduction to Azure SSO

    Azure Single Sign-On (SSO) is an identity authentication mechanism that allows users to log in once and gain access to multiple applications without needing to re-enter credentials. It integrates with Azure Active Directory (Azure AD) and supports modern authentication protocols like SAML, OpenID Connect (OIDC), and OAuth 2.0.

    Organizations use Azure SSO to improve security, user experience, and IT efficiency while reducing password fatigue and helpdesk requests for password resets.


    🔹 Why Use Azure SSO?

    Improves Security – Reduces password-based attacks by enforcing authentication policies.
    Enhances User Experience – Eliminates the need for multiple logins across cloud apps.
    Reduces IT Workload – Minimizes helpdesk tickets for password resets.
    Centralized Access Control – Manages authentication and access policies in one place.
    Supports Hybrid Environments – Works with cloud and on-premises apps.


    🔹 How Azure SSO Works

    Azure SSO uses Azure AD as the identity provider (IdP) to authenticate users. The authentication flow varies based on the authentication protocol used:

    1️⃣ SAML-based SSO – Azure AD sends a SAML token to authenticate the user.
    2️⃣ OAuth 2.0 / OpenID Connect (OIDC) – The user is authenticated via an authorization token.
    3️⃣ Password-based SSO – Azure AD stores credentials and auto-fills login fields for legacy apps.
    4️⃣ Linked-based SSO – Redirects users to a third-party identity provider for authentication.


    🔹 Implementing Azure SSO Using PowerShell

    Step 1: Prerequisites

    Before configuring SSO, ensure:
    ✅ You have Global Admin or Application Administrator role in Azure AD.
    ✅ The application supports SAML, OAuth, or OIDC.
    Azure AD Premium P1/P2 is available for Conditional Access policies (optional).
    ✅ You have PowerShell with AzureAD Module installed.

    To install the AzureAD module, run:

    powershellCopyEditInstall-Module AzureAD -Force -AllowClobber
    

    Connect to Azure AD:

    powershellCopyEditConnect-AzureAD
    

    Step 2: Register an Application in Azure AD

    To enable SSO, register the app in Azure AD.

    Using PowerShell

    1️⃣ Create the App Registration:

    powershellCopyEdit$AppName = "MyAzureSSOApp"
    $App = New-AzureADApplication -DisplayName $AppName
    $AppId = $App.AppId
    

    2️⃣ Create a Service Principal for the App:

    powershellCopyEditNew-AzureADServicePrincipal -AppId $AppId
    

    3️⃣ Assign Required Permissions (Example: Graph API)

    powershellCopyEdit$Permission = "User.Read.All"
    $AppRole = Get-AzureADServicePrincipal -Filter "AppId eq '$AppId'"
    New-AzureADServiceAppRoleAssignment -ObjectId $AppRole.ObjectId -PrincipalId $AppRole.ObjectId -ResourceId $AppRole.ObjectId -Id $Permission
    

    Step 3: Configure SSO for a SAML-based App

    1️⃣ Enable SAML SSO

    • Go to Azure AD > Enterprise Applications > Select App > Single sign-on
    • Choose SAML
    • Set Identifier (Entity ID) and Reply URL (Assertion Consumer Service URL) provided by the app.
    • Download Azure AD Federation Metadata XML and provide it to the app vendor.

    2️⃣ Configure User Attributes & Claims

    powershellCopyEditSet-AzureADServicePrincipal -ObjectId $AppRole.ObjectId -Saml2TokenIssuerName "https://login.microsoftonline.com/{tenant_id}/v2.0"
    

    3️⃣ Assign Users or Groups to the App

    powershellCopyEdit$User = Get-AzureADUser -ObjectId "[email protected]"
    Add-AzureADUserAppRoleAssignment -ObjectId $User.ObjectId -PrincipalId $AppRole.ObjectId -ResourceId $AppRole.ObjectId
    

    🔹 Best Practices for Azure SSO

    Use Conditional Access Policies – Require MFA for risky sign-ins.
    Enforce Role-Based Access Control (RBAC) – Assign least privilege access.
    Use Azure AD Identity Protection – Detect and mitigate suspicious activities.
    Regularly Review Application Permissions – Ensure only necessary apps have access.
    Enable SSO Logging and Monitoring – Track authentication attempts in Azure AD Sign-in Logs.


    🔹 Testing & Troubleshooting SSO

    After setup, test SSO via MyApps (https://myapps.microsoft.com) or direct application login.

    Common Fixes:

    🔹 Incorrect Reply URL? Ensure the correct Assertion Consumer Service (ACS) URL is set.
    🔹 User Not Assigned? Assign users or groups to the application.
    🔹 Invalid SAML Assertion? Check SAML response in Azure AD Sign-in Logs.
    🔹 SSO Failing for On-Prem Apps? Ensure Azure AD Connect is properly configured.


    🔹 Conclusion

    Azure SSO simplifies authentication, enhances security, and streamlines user access to applications. With Azure AD and PowerShell, you can automate SSO setup, manage user permissions, and enforce security best practices.

    🚀 Next Steps:
    Test your SSO setup and monitor sign-in logs.

    🔹 PowerShell with Admin Rights
    🔹 Global Administrator or Privileged Authentication Admin Role


    🔹 Step 1: Connect to Microsoft Entra ID (Azure AD)

    powershellCopyEditInstall-Module -Name AzureAD -Force
    Import-Module AzureAD
    Connect-AzureAD
    

    📌 This will prompt for admin credentials to authenticate.


    🔹 Step 2: Identify Recently Disabled Users

    powershellCopyEdit$DisabledUsers = Get-AzureADUser -All $true | Where-Object { $_.AccountEnabled -eq $false } |
        Select-Object DisplayName, UserPrincipalName, ObjectId
    

    📌 Finds all disabled user accounts.


    🔹 Step 3: Check MFA Enrollment Status

    powershellCopyEditforeach ($User in $DisabledUsers) {
        $MFAStatus = Get-MsolUser -UserPrincipalName $User.UserPrincipalName | Select-Object -ExpandProperty StrongAuthenticationMethods
        if ($MFAStatus -eq $null) {
            Write-Host "MFA not enabled for $($User.DisplayName). Enforcing MFA before re-enabling..." -ForegroundColor Yellow
            # Proceed to enforce MFA
        } else {
            Write-Host "MFA already enabled for $($User.DisplayName). Ready to re-enable." -ForegroundColor Green
        }
    }
    

    📌 This script checks if MFA is enabled before proceeding.


    🔹 Step 4: Enforce MFA Enrollment for Users Without MFA

    powershellCopyEditforeach ($User in $DisabledUsers) {
        $MFAStatus = Get-MsolUser -UserPrincipalName $User.UserPrincipalName | Select-Object -ExpandProperty StrongAuthenticationMethods
        if ($MFAStatus -eq $null) {
            Write-Host "Forcing MFA registration for $($User.DisplayName)..."
            Set-MsolUser -UserPrincipalName $User.UserPrincipalName -StrongAuthenticationRequirements @(@{State="Enabled"; })
            
            # Send notification email to user
            $Subject = "MFA Enrollment Required Before Account Re-Enablement"
            $Body = "Hello $($User.DisplayName),`n`nYour account is being re-enabled, but MFA is required before accessing your account. Please complete MFA enrollment immediately."
            Send-MailMessage -To $User.UserPrincipalName -From "[email protected]" -Subject $Subject -Body $Body -SmtpServer "smtp.office365.com" -Credential (Get-Credential)
            
            Write-Host "MFA enforced and email notification sent to $($User.DisplayName)." -ForegroundColor Cyan
        }
    }
    

    📌 This forces MFA enrollment and notifies the user via email.


    🔹 Step 5: Re-Enable the User Account

    powershellCopyEditforeach ($User in $DisabledUsers) {
        $MFAStatus = Get-MsolUser -UserPrincipalName $User.UserPrincipalName | Select-Object -ExpandProperty StrongAuthenticationMethods
        if ($MFAStatus -ne $null) {
            Write-Host "Re-enabling account for $($User.DisplayName)..." -ForegroundColor Green
            Set-AzureADUser -ObjectId $User.ObjectId -AccountEnabled $true
    
            # Notify the user
            $Subject = "Your Account Has Been Re-Enabled"
            $Body = "Hello $($User.DisplayName),`n`nYour account has been successfully re-enabled. You may now log in using MFA."
            Send-MailMessage -To $User.UserPrincipalName -From "[email protected]" -Subject $Subject -Body $Body -SmtpServer "smtp.office365.com" -Credential (Get-Credential)
    
            Write-Host "Account re-enabled and email sent to $($User.DisplayName)." -ForegroundColor Cyan
        }
    }

  • What is SAML and How to Configure It?

    Introduction to SAML

    Security Assertion Markup Language (SAML) is an XML-based authentication standard used for Single Sign-On (SSO). It allows users to log in once and access multiple applications without entering credentials repeatedly.

    Why Use SAML?

    • Enhanced Security: SAML enables authentication via an identity provider (IdP) rather than storing credentials in multiple applications.
    • SSO Capabilities: Users only log in once to access different apps.
    • Interoperability: Works across various identity providers and service providers.

    How SAML Works

    1. User Requests Access: The user tries to access an application (Service Provider – SP).
    2. Redirect to Identity Provider (IdP): The user is redirected to the IdP for authentication.
    3. Authentication & Assertion: The IdP verifies credentials and sends a SAML assertion (authentication token) back.
    4. User Gains Access: The SP validates the assertion and grants access.

    How to Configure SAML Authentication in Entra ID

    To set up SAML-based authentication in Entra ID, follow these steps:

    Step 1: Register an Enterprise Application

    1. Go to Microsoft Entra ID in the Azure Portal.
    2. Navigate to Enterprise Applications > New Application.
    3. Select Non-gallery application and provide a name for your app.
    4. Click Create.

    Step 2: Configure Single Sign-On (SSO)

    1. In the newly created app, go to Single sign-on.
    2. Choose SAML as the authentication method.
    3. Configure the Basic SAML Configuration:
      • Identifier (Entity ID): https://yourapp.com
      • Reply URL (Assertion Consumer Service URL): https://yourapp.com/sso/callback
      • Sign-on URL: https://yourapp.com/login
    4. Click Save.

    Step 3: Download & Share SAML Metadata

    • Download the Federation Metadata XML from the SAML Signing Certificate section.
    • Provide this XML file to the Service Provider (SP) to complete the integration.

    Step 4: Assign Users to the Application

    1. Go to Users and Groups in the Enterprise Application.
    2. Assign users who should have access to the app.

    Step 5: Test SSO

    1. Click on Test SSO in the SAML settings.
    2. Ensure authentication is successful and users can log in.

    Configuring SAML in Entra ID Using PowerShell

    You can automate the setup using PowerShell with the Microsoft Graph API.

    Step 1: Connect to Microsoft Graph
    powershellCopyEditConnect-MgGraph -Scopes "Application.ReadWrite.All", "AppRoleAssignment.ReadWrite.All"
    
    Step 2: Register an Enterprise Application
    powershellCopyEdit$enterpriseApp = New-MgServicePrincipal -AppId "00000003-0000-0000-c000-000000000000"
    
    Step 3: Configure SAML SSO
    powershellCopyEdit$sp = Get-MgServicePrincipal -Filter "DisplayName eq 'YourAppName'"
    
    # Set SAML properties
    Update-MgServicePrincipal -ServicePrincipalId $sp.Id -PreferredTokenSigningKeyThumbprint "YourThumbprint"
    
    Step 4: Assign Users
    powershellCopyEdit$user = Get-MgUser -UserPrincipalName "[email protected]"
    New-MgUserAppRoleAssignment -UserId $user.Id -ResourceId $sp.Id -AppRoleId "Role ID"
    

    Conclusion

    SAML authentication provides a secure and efficient way for users to authenticate with multiple applications using a single sign-on (SSO) process. Configuring SAML in Microsoft Entra ID enhances security, simplifies user access, and integrates seamlessly with cloud-based applications.

  • Why Automating User MFA Reporting in Entra ID is Essential for Your Organization

    In today’s rapidly evolving cybersecurity landscape, Multi-Factor Authentication (MFA) plays a pivotal role in securing user access to critical systems and data. While Azure Active Directory (now Entra ID) provides a robust and comprehensive MFA solution, ensuring that users are using the right authentication methods and tracking that data can be time-consuming without proper automation.

    In this blog, we’ll explore what it means to identify users with phone-based MFA in Entra ID, why it’s important to automate this process, and how using PowerShell can significantly streamline the task.


    Understanding Phone-based MFA in Entra ID

    Phone-based MFA refers to the method of using a mobile phone or a phone number to authenticate users trying to access applications, services, or systems in Entra ID. This typically involves one of two methods:

    • Phone App Notification: The user receives a push notification to their phone and must approve or deny the login attempt.
    • Phone App OTP (One-Time Password): The user receives a temporary code (OTP) on their phone, which they must enter to complete the authentication.

    While these are robust forms of authentication, not every user within an organization will necessarily have phone-based MFA set up. Additionally, some users may be using alternate authentication methods, such as hardware tokens or biometrics, while others may have not configured any form of MFA at all.

    Based on my experience, phone-based MFA can cause issues with cross-tenant synchronization. Specifically, users who have phone-based MFA set up may face challenges in being provisioned to other tenants. The “NotInScope” and “NotEffectivelyEntitled” errors are often encountered during cross-tenant sync, preventing the proper provisioning of these users. This can cause delays and disrupt workflows, highlighting the importance of understanding and monitoring the MFA configurations of users across tenants.

    Why Track Active Users with Phone-based MFA?

    Ensuring that the right users are utilizing MFA, especially phone-based methods, is a key component of maintaining a secure environment. Here are a few reasons why tracking active users with phone-based MFA is crucial for your organization:

    1. Enhanced Security: With the rise of phishing attacks and data breaches, enforcing MFA provides an additional layer of security, ensuring that even if a user’s password is compromised, unauthorized access is still blocked. Phone-based MFA is one of the most secure forms of two-factor authentication.
    2. Compliance: Many organizations are bound by regulatory requirements, such as GDPR or HIPAA, that mandate MFA for accessing sensitive data. By ensuring that active users have MFA set up, especially phone-based methods, you can stay compliant with industry standards.
    3. User Experience: Simplified user access can lead to fewer friction points in daily workflows. With phone-based MFA, users can easily authenticate themselves without needing complicated hardware setups. Tracking and reporting on these users ensures that your organization stays on top of who’s set up and using MFA.
    4. Auditing and Reporting: Having visibility into the MFA status of your users is important for security auditing. Automated reporting ensures you’re not missing any critical configurations, and it can highlight any gaps that need addressing.
    5. Efficiency: Manual checks for MFA statuses and configurations can be tedious, especially for larger organizations with hundreds or thousands of users. By automating this process, you free up time for other essential tasks.

    Automating the MFA Reporting Process in Entra ID

    Manual auditing of MFA configurations can be error-prone, especially when done across large environments with multiple users. Automating the process not only improves accuracy but also ensures that the task is completed consistently.

    PowerShell provides a simple yet powerful solution for automating the reporting of active users who have phone-based MFA enabled in Entra ID. Here is how you can automate this process using PowerShell:

    Using the AzureAD Module:

    powershellCopy# Connect to Azure AD
    Connect-AzureAD
    
    # Get the list of active users with phone-based MFA enabled
    $usersWithPhoneMFA = Get-AzureADUser -All $true | 
        Where-Object {
            $_.AccountEnabled -eq $true -and
            (Get-AzureADUserMFA -ObjectId $_.ObjectId).Methods |
            Where-Object { $_.MethodType -eq "PhoneAppNotification" -or $_.MethodType -eq "PhoneAppOTP" }
        }
    
    # Display the users
    $usersWithPhoneMFA | Select DisplayName, UserPrincipalName
    

    Using the MSOnline Module:

    powershellCopy# Connect to MSOnline Connect-MsolService # Get the list of active users with phone-based MFA enabled $usersWithPhoneMFA = Get-MsolUser -All | Where-Object { $_.BlockCredential -eq $false -and ( $_.StrongAuthenticationMethods.MethodType -eq "PhoneAppNotification" -or $_.StrongAuthenticationMethods.MethodType -eq "PhoneAppOTP" ) } # Display the users $usersWithPhoneMFA | Select DisplayName, UserPrincipalName


    Why Automate This Process?

    Automating the reporting of active users with phone-based MFA brings a multitude of benefits:

    • Time-Saving: Automation allows you to quickly run reports and receive accurate information, which can otherwise take hours when done manually.
    • Real-Time Visibility: With automation, you get updated data at any time, helping you respond to potential security risks in real-time.
    • Scalability: Whether you have 10 or 10,000 users, automation ensures that the process scales to match your organization’s size without increasing the workload.
    • Accuracy: The automation removes the risk of human error, ensuring that the right users are being reported and that configurations are accurate.

    Conclusion

    Tracking active users with phone-based MFA is essential to maintaining security and compliance within your organization. By automating this process with PowerShell, you can save valuable time, improve reporting accuracy, and make better, data-driven decisions regarding your organization’s security posture.

    Automating these tasks also prepares your organization to scale efficiently and ensures that all users are adhering to the security standards you’ve set.

    If you haven’t yet automated your MFA reporting process, consider implementing a PowerShell solution and integrate it into your IT operations today. It’s a small investment that will yield significant improvements in both security and efficiency.

    Azure AD (now Entra ID) manages user access and authentication:

    1️⃣ Create a new Azure AD Tenant:

    powershellCopyEditNew-AzADServicePrincipal -DisplayName "CompanyAD"
    

    2️⃣ Add users & assign roles:

    powershellCopyEditNew-AzADUser -DisplayName "Admin User" -UserPrincipalName "[email protected]" -PasswordProfile (New-Object -TypeName Microsoft.Open.AzureAD.Model.PasswordProfile -Property @{Password = "SecurePass123!"})
    

    3️⃣ Enable Multi-Factor Authentication (MFA):

    powershellCopyEditSet-MsolUser -UserPrincipalName "[email protected]" -StrongAuthenticationRequirements @(New-Object -TypeName Microsoft.Online.Administration.StrongAuthenticationRequirement -Property @{RelyingParty = "*"; State = "Enabled"})
    

    Why? Azure AD ensures secure authentication, integrates with SSO, and supports Conditional Access to prevent unauthorized logins.


    🌐 Step 3: Set Up Azure Virtual Network (VNet)

    Azure VNets allow private, secure communication between resources (like AWS VPC).

    powershellCopyEditNew-AzVirtualNetwork -Name "CompanyVNet" -ResourceGroupName "CompanyResources" -Location "EastUS" -AddressPrefix "10.0.0.0/16"
    

    Add a subnet for workloads:

    powershellCopyEditAdd-AzVirtualNetworkSubnetConfig -Name "WebSubnet" -VirtualNetwork (Get-AzVirtualNetwork -Name "CompanyVNet") -AddressPrefix "10.0.1.0/24"
    

    Why? A VNet is required to connect virtual machines, databases, and cloud apps securely.


    💻 Step 4: Deploy Virtual Machines (VMs) for Workloads

    To host applications, databases, or remote desktops, deploy Azure Virtual Machines:

    powershellCopyEditNew-AzVM -ResourceGroupName "CompanyResources" -Name "CompanyWebServer" -Location "EastUS" -VirtualNetworkName "CompanyVNet" -SubnetName "WebSubnet" -Image "Win2022Datacenter" -Size "Standard_B2ms"
    

    Why? VMs are essential for compute power, running legacy applications, or supporting cloud-based workloads.


    💾 Step 5: Create Azure Storage Accounts for Business Data

    Azure Storage Accounts allow businesses to store and manage files, backups, and logs:

    powershellCopyEditNew-AzStorageAccount -ResourceGroupName "CompanyResources" -AccountName "companyfiles" -Location "EastUS" -SkuName "Standard_LRS"
    

    Why? Storage accounts support blobs, file shares, queues, and tables, making it ideal for structured and unstructured data.


    🚀 Step 6: Implement Network Security (NSGs & Firewalls)

    To secure Azure workloads, configure Network Security Groups (NSGs) and Azure Firewall:

    1️⃣ Create an NSG and apply security rules:

    powershellCopyEditNew-AzNetworkSecurityGroup -ResourceGroupName "CompanyResources" -Location "EastUS" -Name "CompanyNSG"
    Add-AzNetworkSecurityRuleConfig -NetworkSecurityGroupName "CompanyNSG" -Name "AllowWeb" -Direction Inbound -Priority 100 -Access Allow -SourceAddressPrefix "*" -SourcePortRange "*" -DestinationAddressPrefix "*" -DestinationPortRange "80,443" -Protocol Tcp
    

    2️⃣ Deploy Azure Firewall:

    powershellCopyEditNew-AzFirewall -Name "CompanyFirewall" -ResourceGroupName "CompanyResources" -Location "EastUS" -Sku "Standard"
    

    Why? NSGs protect workloads from cyber threats, while Azure Firewall enables advanced network security policies.


    📊 Step 7: Enable Monitoring & Security

    Monitor performance, security, and alerts using Azure Monitor and Defender for Cloud.

  • How to Quickly Identify and Stop Phishing, Spam, and Malware Emails Using PowerShell

    Phishing, spam, and malware-laden emails are still a major threat to organizations, even with security tools like Microsoft Defender for Office 365 in place. Attackers evolve their techniques to bypass filters, making it critical for IT professionals to quickly analyze and block these threats.

    In this blog, we’ll explore how to quickly determine if an email is malicious and use PowerShell to identify, investigate, and stop phishing attempts in Microsoft Exchange Online.


    🔹 1. How to Identify a Suspicious Email Quickly

    Before using PowerShell, here are quick ways to spot a malicious email:

    Check the sender’s email domain → Look for spoofed domains (e.g., @microsft-support.com instead of @microsoft.com).
    Hover over links (DO NOT CLICK) → If URLs contain random characters or redirect to unknown domains, they are likely phishing.
    Look for urgency or threats → Phrases like “Your account will be locked in 24 hours!” are red flags.
    Check for spelling errors & odd formatting → Professional companies don’t send typo-ridden emails.
    Check email headers for anomalies → Fake “From” addresses or mismatched domains are common in phishing emails.

    🚨 Automate these checks with PowerShell!


    🔹 2. Investigating Suspicious Emails Using PowerShell

    🔍 Find Emails by Subject, Sender, or Date

    To search for phishing emails across mailboxes:

    powershellCopyEditSearch-Mailbox -Identity "[email protected]" -SearchQuery 'Subject:"Urgent Security Notice"' -TargetMailbox [email protected] -TargetFolder PhishingReports
    

    👉 What this does:

    • Searches all mailboxes for emails with “Urgent Security Notice” in the subject.
    • Moves them to the PhishingReports folder in the [email protected] mailbox for further analysis.

    📧 Check Email Headers for Spoofing & Authentication Failures

    To inspect email headers and verify SPF, DKIM, and DMARC:

    powershellCopyEditGet-MessageTrace -SenderAddress "[email protected]" -StartDate (Get-Date).AddDays(-3) -EndDate (Get-Date)
    

    👉 What this does:

    • Traces emails sent from [email protected] in the last 3 days.
    • Helps identify whether attackers are spoofing legitimate domains.

    🛑 Identify Users Who Clicked on a Phishing Email
