SSO Configurations for Amazon Web Services (AWS)

This document provides a step-by-step guide for setting up SSO Configuration to configure AWS IAM Identity center, allowing users to sign in to Amazon Web Services (AWS) using their OneIdP credentials and securely access these services.

Pre-requisites

1. The Custom Domain for which you are authorising, should be verified through OneIdP. 

2. Users belonging to custom domain should be added to Scalefusion Dashboard and migrated to OneIdP.

3. IT Admins should have access to Amazon Web Service’s (Service Providers') admin console.

4. Users should be added to AWS portal

Create SSO Configuration for AWS

1. Sign in to Scalefusion Dashboard and navigate to OneIdP > SSO Configuration 

2. Click on New SSO Configuration button on top right.
   

   

3. This opens the SSO Configuration wizard with following tabs on the left panel:

   1. Application Basics

   2. SSO Scope Management

   3. Permissions

   4. SSO Settings

   5. Conditional Access

   6. User Facing Messages
      Navigate to each tab and enter required details. You can navigate to next tab only after you have entered complete details in the current section. All are explained in detail below.
      
      
      

Application Basics 

Configure basic application details by entering the following:

• Select Application Type: Select Amazon Web Services as application type from the drop-down. 

• Enter Application Name: Enter a name for your App which will be an identifier for your configuration. The name must be at-least 5 characters long. The maximum allowed length is 128 characters.

• Select Hosting Type: This will be pre-selected as Cloud 

• Select Domains: All the custom domains you have configured and verified using OneIdP, will be listed here. Select the domain(s) which you want to be SAML SSO enabled.

• Enter Login URL: Provide URL that you use to sign in to that service. In case of AWS, it will be pre-populated as https://aws.amazon.com
  
  Once you have entered all details click Next
  
  

SSO Scope Management

With SSO scope management you can configure the procedure for managing the users who will be accessing this application. It basically allows how SAML settings for the users are going to be managed. Following are the settings:

User assignment 

SSO Configuration would allow only assigned users to access the app. Choose one from the following options:

1. Allow all users imported to Scalefusion to access the application: All users (belonging to the domain) imported to Scalefusion and migrated to OneIdP will be allowed to access the application.

2. Allow only assigned users to access the application: Only the user(s) whom you have assigned the SSO configuration, will be allowed to access the application. With this option, after SSO configuration is created, you need to manually select and assign the users.

   1. Revoke access for all users once when the configuration is saved: If this is checked, the access is revoked from the users who are currently assigned with the configuration. As a result, it will invalidate all user sessions and logout users from their current running session.
      
      
      

Enforcement Rules 

From here, you can configure and enforce users that at what point of time SSO Configuration should invalidate the current session and logout users. Following options can be selected:

1. Immediately on User Assignment and post grace period if applied: Once SSO configuration is assigned to user

2. Immediately on User Un-Assignment: When user is unassigned the SSO configuration

3. Immediately on Deleting this configuration: When SSO configuration is deleted from Scalefusion Dashboard

   Users will not get logged out in case of Amazon Web Services

   
   

   

Permissions

Here, you do not need to grant any additional permissions. Click Next to go to the next step.

SSO Settings

This section allows admins to configure the Service Provider (AWS) settings and obtain the SSO URLs which will be added on the AWS portal.

1. Enter the Service Provider details on Scalefusion Dashboard, as provided in the web-console of your service provider SSO/SAML section

   1. Service Provider Entity ID: If your service provider has given you an Entity ID, also known as an audience or identifier, please enter it here. Otherwise, leave it blank to have it automatically decoded from the incoming request.

   2. Service Provider ACS URL: If your service provider has provided an ACS URL, sometimes also called a destination or recipient, then please enter it here, else leave it blank to auto-decode it from the incoming request
      

      

      
      
      

   3. SAML Subject Name Id Format & Value: Most service providers accept Email as the SAML Subject NameID as the user identifier. Change this only if your service provider wants a different value. Here, select the following:  

      1. Select Service Provider Name Id Format: Select email_address from the drop-down

      2. Select OneIdP User Value: Select Username from the drop-down
         
         

   4. Session Duration: Configure the duration (in days) after which the user will be asked to re-authorize. Make sure to select a value potentially higher than your Service providers' session value. It can be anywhere from 5 to 90 days.
      

2. OneIdP SSO URL: Copy this URL from Scalefusion Dashboard and paste it on Amazon Web Services console by following the steps below:

   1. Login to AWS portal and search for IAM Identity Center. In the search results, click on IAM Identity Center
      
      

   2. On the IAM Identity Center Setup page, click on Confirm Identity Source / Go to Settings
      
      

   3. This opens Settings page. On Settings page, click on Actions drop-down and select Change Identity Source
      

      

      
      

   4. On the next page, make sure External Service Provider is selected. Click Next to go to next page
      
      

   5. This will open Configure External Identity Provider page. Scroll down to go to Identity Provider metadata section. Under this section, enter the following:

      1. IdP sign-in URL: Copy the OneIdP SSO URL from Scalefusion Dashboard and paste it here

      2. IdP issuer URL: Copy the OneIdP SSO URL from Scalefusion Dashboard and paste it here

      3. IdP Certificate: Download OneIdP Verification Certificate from Scalefusion Dashboard (SSO Settings page) and upload it here. Click Next to go to next page
         

         You can either provide IdP sign-in and issuer URL, upload IdP Certificate or download metadata file from Scalefusion Dashboard (SSO Settings page) and upload it under IdP SAML metadata

         
         
         
         

   6. On the next page, review and confirm all the details. After reviewing, enter ACCEPT in the last field and click on Change Identity Source
      
      

3. Now, on Scalefusion Dashboard, click Next in SSO Settings

Conditional Access

From this section you can define the additional conditions on the basis of which users will be allowed/disallowed from accessing the application on device. This is divided into following sections:

1. Conditional Access Settings

2. Access Exceptions

Conditional Access Settings

Device Policy

1. For Android, iOS/iPad OS, Windows & macOS, Linux, Chrome OS: Choose one from the following two conditions:

   1. Only if the device is managed by Scalefusion: The application will be accessible only on devices managed (enrolled) by Scalefusion.
      

   2. If the device is managed by Scalefusion or an OTP using Scalefusion Authenticator app from a managed device: The application is accessible if any of the following conditions is met:

      1. Device is managed by Scalefusion: If device is managed you will not be asked to enter OTP for authentication, or

      2. If device is unmanaged, OTP is required for authentication. OTP can be taken from Authenticator app installed on a Scalefusion managed device.

   3. Allow users to access by setting up MFA using third party authenticator app or OTP sent on email: This option is activated only when Multi-factor Authentication is enabled in Directory Settings.
      Note: The left side panel is for configuring Device Policy on Android & iOS/iPad OS and right side is for Windows & macOS and Linux, ChromeOS below them. Hence, you can configure separate device policies based on platform.
      
      
      

Browser Policy

From here, you can select one or more browsers and specify minimum versions on which you want to allow the access to the application. Following are the options:

• All Browsers

• Google Chrome with minimum version 

• Microsoft Edge with minimum version

• Safari with minimum version

• Mozilla Firefox with minimum version

Important Points on Browser Policy:

1. By default all browsers are allowed.

2. Only major versions are validated. For eg. if you mention browser version: 23.5.8.10 then the respective browser with minimum major version(23) will be allowed. After configuring Device Policy and Browser Policy, click Next
   

Access Exceptions

From this section you can configure the exceptions where the users are allowed to access the applications even if the conditions are not met. In general, these exceptions will be useful or addresses scenarios where :

1. IT Admins have setup Android Enterprise using Google Workspace Or

2. IT Admins have setup Apple User Enrollment with ABM/ASM federated to Google Workspace

Following are the exceptions that can be configured:

1. Enrollment Exceptions

   1. Allow users to access the application till they enroll their first device: Allows users to access the application till they enroll at-least one device. This option is helpful in conditions where the enrollment steps requires them to authenticate with the service provider. With this, you can also configure the following:

      1. Maximum sessions allowed per user: Configure no. of sessions that should be exempted. It can range from 1 to 3. Ideally 1 session per user is recommended.

      2. Configure the OS where the exceptions are applied: Select the platform(s) on which this exemption would be allowed to users. 

2. User Exceptions
   Here you can add the users who are always exempted from the conditions and will never be asked to manage their device. Enter comma separated email addresses of users or click on Add Users on the right and in the new window, select the users who should be exempted.
   Note: These users still need to sign in with their OneDirectory credentials if they fall under the SSO Scope, however the conditions will not be enforced.
   
   
   

User Facing Messages

User Facing Messages helps admins configure messages that end users may be shown when they are unable to access the application if any of the compliance conditions are not met. You can configure messages under following:

• Configure Instructions for a Non-Compliant Device: This message is shown when the device is not compliant and needs to be enrolled to Scalefusion

• Configure Instructions for a Non-Compliant Browser: Shown when the browser is not compliant as per configurations 

• Configure a Message to be displayed when Access is Denied: Any other cases where access to application is denied.

There are some pre-configured messages displayed on Dashboard which you can edit as per requirement.

After configuring user facing messages, click on Save

The SSO configuration is created and listed on SSO Configuration page as a separate card with the name you have defined. You can create multiple SSO configurations in the same manner.

The next document explains how the configurations can be managed and other actions you can perform through SSO configurations.
