Improve your Azure Multi-Factor Authentication Notifications

Improve your Azure Multi-Factor Authentication Notifications

Recently, Uber appeared to be hacked in what is called a MFA Fatigue attack. The attacker continuously sent MFA requests to an end user hoping they would accidentally approve one of them. Microsoft has several items to help prevent MFA fatigue attacks that you can configure and enable for your end users. Traditionally, MFA notifications are push notifications where a user can either accept or deny the request. Some improvements to this have been multiple number options where the end user must select one of four numbers that is presented on the screen they are logging into. The problem with this is that leaves a 1 in 4 chance an accidental selection may result in unauthorized access.

Configure Fraud Alerts

Fraud Alerts allow your users to report fraud if they receive a two-step verification request that they didn’t initiate and automatically block their account from sign-on.

Connect to Exchange Online PowerShell with an Azure Managed Identity

Connect to Exchange Online PowerShell with an Azure Managed Identity

Recently the Exchange Online Module v2 came out with support for connecting to Exchange Online via a managed identity. The module has several parameters:

  1. ManagedIdentity
  2. ManagedIdentityAccountId
  3. Organization

When using the ManagedIdentity parameter you must also call the Organization parameter which is the initial, or ‘.onmicrosoft’ domain.

What You Will Need

  • PowerShell
  • Az PowerShell Module (install-module az)
  • The Microsoft Graph SDK (install-module Microsoft.Graph

Create the Managed Identity, Permissions, and Runbook

Connect to Azure

First thing we must do is connect to Azure using the Az module. Open a PowerShell window and run

Connect-AzAccount

Create a Resource Group

After we are connected we need to create a Resource Group to house everything. In my example I will create a new Resource Group in the Central US region.

$rgname = "rg-exchangeautomation"
$location = "centralus"
New-AzResourceGroup -Name $rgname -Location $location

Create the Automation Account

Next, we need to create the Automation Account that runs … Continue...

Creating a Microsoft 365 Automated Off-boarding Process with SharePoint, Graph API, and PowerShell

Creating a Microsoft 365 Automated Off-boarding Process with SharePoint, Graph API, and PowerShell

In this write-up I will be creating a basic off-boarding automation that uses SharePoint as the front end, and PowerShell, the Graph API, and Azure Runbooks as the back-end. HR will input the users UPN or Email, offboard date/time, and a forwarding address to forward email to. Once the off-boarding datetime is within 1hr the automation will check the user in Azure AD to ensure its valid, the forwarding user is valid in Azure AD, document in SharePoint the users e-mail address, any and all licenses, and all group memberships. After that, it will proceed with the off-boarding where it will remove all licenses from the user, remove all group memberships, and forward email to our forwarding user. It will log everything back to SharePoint where one can review it.

Off-Boarding Stages

In Pending we have just submitted our user and the automation has not seen it, or it … Continue...

Getting Started with Bicep, an ARM DSL for Azure

Getting Started with Bicep, an ARM DSL for Azure

Note: This is one part of a several part blog series that goes through Azure Bicep

What is Azure Bicep

Bicep is a Domain Specific Language or DSL, for deploying Azure resources in a declarative manner. It ‘aims to drastically simplify the authoring experience with a cleaner syntax and better support for modularity and code re-use. Bicep is a transparent abstraction over ARM and ARM templates, which means anything that can be done in an ARM Template can be done in Bicep.’1

Bicep moves away from the JSON syntax used by ARM Templates to something similar to HCL in Terraform. The end result is a syntax that is easier to both read and write. Bicep code is converted into ARM Template code (JSON), and then the resulting ARM Template code (JSON) is used to deploy your Azure resources.

One of the key benefits to Bicep to another DSL like … Continue...

Text your Azure Infrastructure with Serverless Computing and PowerShell

Text your Azure Infrastructure with Serverless Computing and PowerShell

Due to COVID-19 and social distancing, I have found myself camping a lot more than in previous years. One problem that has brought with it is the high probability of being somewhere with no cell phone data service or poor cell phone data. Couple with my incredibly poor memory, I have often forgotten to turn off servers to save on cost in my dev or test environment until I’m out in the woods. Also, I wanted the ability to use Google Voice as well as Siri in my car or even at home, to turn off, turn on, or check the status of my servers in my Azure tenants. This has even come in handy when I didn’t have my phone on me and had to use the wife’s phone to turn on or off some servers in my tenant. (I set it to only accept messages from my phone … Continue...

Deploy and Manage Azure Infrastructure Using Terraform, Remote State, and Azure DevOps Pipelines (YAML)

Deploy and Manage Azure Infrastructure Using Terraform, Remote State, and Azure DevOps Pipelines (YAML)

Overview

In this article, I will be showing you how to create an Azure DevOps CI/CD (continuous integration / continuous deployment) Pipeline that will deploy and manage an Azure environment using Terraform. Terraform is a tool for building, changing, and versioning infrastructure safely and efficiently.

Configuration files (In our case, it will be named ‘Main.tf’) describe to Terraform how you want your environment constructed. “Terraform generates an execution plan describing what it will do to reach the desired state, and then executes it to build the described infrastructure. As the configuration changes, Terraform can determine what changed and create incremental execution plans which can be applied.”1

By creating an entire CI/CD pipeline, we can automate our infrastructure-as-code (IaC) deployment. When we have made a change to our Terraform code (adding something, removing something, changing something), the Pipeline will automatically log in to our Azure environment, add any new … Continue...

Configure Autopilot Hybrid Azure-AD and ADDS Domain Join

Configure Autopilot Hybrid Azure-AD and ADDS Domain Join

Prerequisites

Hybrid Azure AD join requires devices to have access to the following Microsoft resources from inside your organization’s network. These addresses must be accessed using the SYSTEM context. If you are using Auto Pilot this will be accessed during the enrollment status part:

  • https://enterpriseregistration.windows.net
  • https://login.microsoftonline.com
  • https://device.login.microsoftonline.com
  • https://autologon.microsoftazuread-sso.com (If you use or plan to use seamless SSO)

To verify if the device is able to access the above Microsoft resources under the system account, you can use Test Device Registration Connectivity script.

Backup and Restore your Intune Configuration using PowerShell

Backup and Restore your Intune Configuration using PowerShell

I found this fantastic PowerShell module from jseerden that queries Microsoft Graph, and allows for cross-tenant Backup & Restore of your Intune Configuration. The Intune Configuration is backed up as JSON files in a given directory. The module allows an administrator to backup, restore and even compare different Intune backup sets.

Pre-Requisites

The module requires a total of 3 modules to be present, you can install them by running the following commands in an administrative PowerShell prompt:

AzureAD Module

  1. AzureAD (Install-Module -Name AzureAD)

MSGraphFunction Module

  1. MSGraphFunction (Install-Module -Name MSGraphFunctions)

IntuneBackupandRestore Module

The IntuneBackupandRestore PowerShell module is hosted on the PowerShell Gallery. You can install it by running the following command in an administrative PowerShell prompt:

Install-Module -Name IntuneBackupAndRestore

Connect to Microsoft Graph

Next, we will connect to Microsoft Graph using the “Microsoft Intune PowerShell” application in AzureAD, so you don’t need to create your own … Continue...

Office 365 Email Address Policies with Azure Automation

Office 365 Email Address Policies with Azure Automation

Email address policies (EAP) define the rules that create email addresses for recipients. By setting up policies you can guarantee your users will have certain email address that follow the rules you have set in place. Unfortunately, in Office 365 Exchange Online there are no email address policies you can set for your users. In a larger organization where multiple people may be creating and editing users in Exchange Online, it’s possible that not all your users are following the address scheme you or your company has implemented. In this article I will leverage PowerShell and Azure RunBooks to make sure all of my users adhere to my companies EAP.

Setting up the Azure Automation Resources

In the next section I will go over what Azure resources we will be creating and what each one is responsible for. You can skip ahead to the configuration script below which will create … Continue...

Sync Office 365 / AzureAD down to ADDS

Sync Office 365 / AzureAD down to ADDS

I recently found myself needing to build out an on premise Active Directory environment and populate it from objects found in Office 365 (AzureAD). The local Active Directory would then be configured as the identity source and would sync up to AzureAD using Azure AD Connect. Unfortunately, Azure AD Connect is currently a one way sync from your on premise Active Directory Domain Services environment to AzureAD and wont sync objects down. AADConnect does have the ability to match our AzureAD objects to their corresponding Active Directory objects but, if an attribute like City, Phone Number, Department, Title, etc. is present in your existing AzureAD and not in ADDS, the attribute may remain in AzureAD but not replicate down to ADDS. So we will want to copy over as many attributes from AzureAD to our local Active Directory as possible in preparation for the Azure AD Connect sync. We will … Continue...
