As business applications move to cloud-hosted solutions, users experience password fatigue due to multiple logons for different applications.

Single sign-on (SSO) technologies aim to unify identities across systems, reducing the number of different credentials users need to remember or input to access resources.

SSO is convenient for users, but it presents new security challenges, such as allowing attackers to gain access to multiple resources if a user's primary password is compromised.

If sensitive information is stored in cloud-hosted services, it's essential to secure access by implementing two-factor authentication and zero-trust policies.

You can get an Azure subscription using your Office 365 account. Simply visit Azure.com and enter your Office 365 username and password.

To get started, you'll need to type in your details in the 'About you' screen. This is a crucial step in the process.

Once you're done, click on Sign up at the bottom of the page. This will complete the initial setup.

If you have an Azure Account, you can also use it to get an Office 365 subscription. Any account with Global Admin or Billing Admin permissions in Azure AD can be used to sign up.

To get an Office 365 subscription, open the Office 365 product page and select a plan. Then, type in your Azure account credentials and sign in.

After signing in, click on Try now on the Checkout page and click continue on the order receipt. This will complete the purchase.

If you're new to Active Directory, you're in luck because there's a free video course available to help you get started.

The course covers the essentials of Active Directory, which is a fundamental component of Microsoft 365.

One of the key benefits of using PowerShell is that it can automate tasks, such as assigning licenses or configuring mailbox settings.

PowerShell is the preferred language for managing and configuring many Microsoft products.

To take advantage of this free video course, you can visit the provided link.

This course will give you a solid foundation in Active Directory and help you understand how to use PowerShell to manage your Microsoft 365 environment.

Configuring Azure AD Connect is a crucial step in setting up Azure O365. You'll need to log in to the Office Admin portal as the tenant administrator and open the Sync users from your Windows Server Active Directory setup action.

To install the Microsoft Azure Active Directory Module for Windows PowerShell, run Install-Module MSOnline on a computer joined to your AD domain. This will allow you to install Azure AD Connect and configure directory synchronization.

The Azure AD Connect tool requires a Custom installation to perform a Custom installation of Azure Active Directory Connect. On the "User sign-in" page, select Do not configure as the "Sign On method". On the "Identifying Users" page, select mS-DS-ConsistencyGuid from the "Source Anchor" drop-down.

Here's a summary of the steps to enable directory synchronization:

When setting up Microsoft 365, it's essential to understand what services are included. Microsoft 365 services include Exchange Online, Exchange Online Protection, Delve, Skype for Business Online, Microsoft Teams, SharePoint, OneDrive, Project Online, Portal and shared, Microsoft Entra ID, Microsoft Entra Connect, and Office.

Here's a list of the applications included with Microsoft 365:

Note that some services, like Microsoft 365 Apps for enterprise client downloads, On-premises Identity Provider Sign-In, and Microsoft 365 (operated by 21 Vianet) service in China, are not included with ExpressRoute for Microsoft 365.

To prepare your tenant for federation, you'll need to add custom domains to Microsoft 365. This is a crucial step, as you cannot federate your "onmicrosoft.com" domain. Additionally, the custom domain you add cannot be set as the default domain.

You'll need to create the Microsoft 365 application in Duo, enable AD federation to Microsoft 365 using Duo SSO, and verify SSO. This process can be repeated for each additional domain you want to federate.

Before you start, make sure you've installed the Microsoft Azure Active Directory Module for Windows PowerShell on a domain-joined computer. You'll also need to install the Azure AD Connect tool.

Here's a list of steps to prepare your tenant for federation:

It's also essential to note that once you federate a given Microsoft 365 domain with an external identity provider, like Duo SSO, you may no longer create new users in that domain from the Entra ID or Microsoft/Office 365 consoles. You'll need to create the users in your source Active Directory and have Azure AD Connect sync them from the on-premises directory into the cloud.

To connect to SharePoint Online, you can download and install the SharePoint Online Management Shell module from Microsoft's site or install it from the PowerShell Gallery using the Install-Module command.

You can connect a PowerShell session to SharePoint Online using the Connect-SPOService cmdlet, specifying the tenant admin SharePoint URL, which includes your tenant name followed by "-admin.sharepoint.com".

The credential object is used to continue using your credentials, and you can also try connecting without specifying the -Credential parameter if you receive an error message that the website does not support SharePoint Online credentials.

LegacyAuthProtocolsEnabled should be set to "true", and RequireAcceptingAccountMatchInvitedAcount should be set to "false" to use a PSCredential object, and any changes to these values should be verified for security or third-party integrations that might be affected.

Security and Authentication is a crucial aspect of Azure O365. Azure MFA provides better insights into the number and types of authentications done in a specific period of time.

Admins can generate various generic and specific reports for better control. These reports can be exported to Excel sheets and can be used for diagnosing and analyzing frauds, account blocks, and MFA Server status.

Azure MFA offers customization options such as specifying the phone number for authentication calls and customizing voice greetings. This flexibility allows businesses to tailor the MFA experience to their specific needs.

Here are the different types of authentication methods available in Azure MFA:

Multi-factor authentication is an additional security mechanism that requires another form of authentication beyond your account password. At a minimum, administrator accounts should have multi-factor authentication enabled as these are elevated accounts that require extra security.

Duo Authentication is a robust security mechanism that provides an additional layer of protection beyond your account password. It's an essential feature for securing regular user accounts and protecting against stolen credentials.

The Duo authenticator app generates an OTP or sends a push notification that can be used for authenticating applications and other devices. This app is installed on your smartphone and provides an additional form of authentication.

Successful verification of your primary credentials by Active Directory redirects back to Duo, where you'll complete two-factor authentication and then return to Microsoft 365 to complete the login process.

You can also log into Microsoft 365 using Duo Central, a cloud-hosted portal that allows users to access all of their applications in one spot. To use Duo Central, you'll need to add Microsoft 365 as an application tile and then log in to Duo Central to initiate the authentication process.

The Duo Universal Prompt provides a simplified and accessible Duo login experience for web-based applications, offering a redesigned visual interface with security and usability enhancements. This prompt is already updated for the Microsoft 365 application hosted in Duo's service, so you don't need to take any action to update the application itself.

If you created your Microsoft 365 application before March 2024, you can activate the Universal Prompt experience for users from the Duo Admin Panel. However, if you created your application after March 2024, the Universal Prompt is activated by default.

To enable AD Federation to Microsoft 365 using Duo SSO, you'll need to follow a series of steps, including installing the Microsoft Azure Active Directory Module for Windows PowerShell and running a PowerShell script to federate your domain to Duo Single Sign-On. This process may take two hours or more, so be sure to plan accordingly.

Once you've federated your domain, you can verify SSO by navigating to https://login.microsoftonline.com and entering your Microsoft 365 email address that matches your federated custom domain. This will redirect you to Duo Single Sign-On to begin authentication.

Here's a summary of the Duo authentication process:

By using Duo authentication, you can provide an additional layer of security for your Microsoft 365 users and protect against stolen credentials.

Service accounts can be a challenge when it comes to authentication, especially if you're using devices that don't support modern authentication.

You can use the WS-Trust setting to allow service accounts to continue sending e-mail, but you'll need to create Duo user accounts for them.

Service accounts are often used for devices like copiers, printers, or scanners that can't handle modern authentication methods.

To set up WS-Trust, you'll need to follow the instructions in the Create the Microsoft 365 Application in Duo section.

To create an app password, navigate to https://aka.ms/mfasetup and select the App Passwords menu.

You'll then need to select the Create button and give the app password a name to indicate its purpose.

The app password will be displayed after clicking Next, and you should save it in a password credential manager as you won't be able to retrieve it.

You can use the new app password to create a new PSCredential object, which will replace your regular account password.

This allows applications that don't support multi-factor authentication to use app passwords, adding an extra layer of security without requiring constant second-factor authentication.

Here's a step-by-step summary of the process:

To connect to the Security Center, use the Connect-IPPSSession cmdlet with your credential object. This will allow you to create compliance cases, search the admin audit log, and create retention policies.

You'll need to specify the correct connection URI depending on your tenant type. For example, if you're connecting to an Office 365 Germany tenant, use "https://ps.compliance.protection.outlook.de/PowerShell-LiveID" as the -ConnectionUri parameter value.

Once connected, you can verify a successful connection by running a command like Get-AdminAuditLogConfig. This will help you verify your tenant configuration settings.
