Multi-Factor Authentication (MFA) for Amazon Workspaces
As many organizations are now shifting towards remote work and hybrid-work, there is a need to find various ways to enable remote working. VDI solution is one of their choices. AWS WorkSpaces can provide a quick win VDI solution but it still needs to spend efforts to set up some authentications and security settings. Easy access also brings up a set of challenges associated with security concerns to stop your data from being accessed by unauthorized users protecting it from various sorts of cyberattacks.
Some SME companies, may not have their own RADIUS (Remote Authentication Dial-In User Service) server and OTP (one-time password) server to enable MFA. Easy access also brings up a set of challenges associated with security concerns to stop your data from being accessed by unauthorized users protecting it from various sorts of cyberattacks. So here the miniOrange Two-Factor Authentication solution comes into the frame. When you enable MFA for AWS Workspaces, your users enter their username and password (first factor) as usual, and they have to enter an authentication code (the second factor) which will be shared on your virtual or hardware MFA solution to get access to AWS Workspace Client.
miniOrange provides 15+ authentication methods for Two-Factor Authentication (MFA) or Multi-factor Authentication (MFA) for various use cases like AWS. It allows IAM users and organizations to set up certain authentication and settings which includes password restrictions, restricting sign-in methods, Google or Microsoft Authenticator, Authy 2-Factor authentication app & miniOrange Authenticator app. You can follow this detailed guide to setup MFA over AWS Workspaces.
Types of MFA Authentication with RADIUS
The 2-factor authentication can be of two types depending on the VPN clients.
VPN Clients that support RADIUS Challenge.
VPN Clients that do not support RADIUS Challenge.
miniOrange MFA authentication for Amazon (AWS) WorkSpaces Client Login
miniOrange accomplishes this by acting as a RADIUS server that accepts the username/password of the user entered as a RADIUS request and validates the user against the user store as Active Directory (AD). After the first level of authentication, miniOrange prompts the user with 2-factor authentication and either grants/revokes access based on the input by the user.
Primary authentication initiates with the user submitting his Username and Password for Amazon (AWS) WorkSpaces.
User request acts as an authentication request to RADIUS Server(miniOrange).
miniOrange RADIUS server passes user credentials to validate against the credentials stored in AD (Active Directory) / Database.
Once the user's first level of authentication gets validated AD sends the confirmation to RADIUS Server.
Now miniOrange RADIUS Server asks for a 2-factor authentication challenge to the user.
Here user submits the response/code which he receives on his hardware/phone.
User response is checked at miniOrange’s RADIUS Server side.
On successful 2nd factor authentication the user is granted access to AWS Workspaces login.
What are different MFA methods for Amazon (AWS) WorkSpaces supported by miniOrange?

4. Configure Your User Directory (Optional)
miniOrange provides user authentication from various external sources, which can be Directories (like ADFS, Microsoft Active Directory, Azure AD, OpenLDAP, Google, AWS Cognito etc), Identity Providers (like Okta, Shibboleth, Ping, OneLogin, KeyCloak), Databases (like MySQL, Maria DB, PostgreSQL) and many more. You can configure your existing directory/user store or add users in miniOrange.
Configure your existing directories such as Microsoft Active Directory, Azure, OpenLDAP, etc.
Click on External Directories >> Add Directory in the left menu of the dashboard.
Select Directory type as AD/LDAP.
STORE LDAP CONFIGURATION IN MINIORANGE: Choose this option if you want to keep your configuration in miniOrange. If active directory is behind a firewall, you will need to open the firewall to allow incoming requests to your AD.

Enter LDAP Display Name and LDAP Identifier name.
Select Directory Type as Active Directory.
Enter the LDAP Server URL or IP Address against LDAP Server URL field.
Click on Test Connection button to verify if you have made a successful connection with your LDAP server.
In Active Directory, go to the properties of user containers/OU's and search for Distinguished Name attribute.
Enter the valid Bind account Password.
Click on Test Bind Account Credentials button to verify your LDAP Bind credentials for LDAP connection.
Search Base is the location in the directory where the search for a user begins. You will get this from the same place you got your Distinguished name.
Select a suitable Search filter from the drop down menu. To use custom Search Filter select "Write your Custom Filter" option and customize it accordingly.
You can also configure following options while setting up AD. Enable Activate LDAP in order to authenticate users from AD/LDAP. Click on the Save button to add user store.
Here's the list of the attributes and what it does when we enable it. You can enable/disable accordingly.
