Client VPN has visibility into the group membership of authenticated users. For example, heavy internet video streaming traffic would go out directly to the internet across the users own network.įor more granular access control, I can configure SAML group-specific authorization rules. Any traffic going to destinations outside of the VPC IP range bypasses the VPN. In my walk through, I set up Client VPN split-tunneling to forward only traffic destined to the target VPC over my VPN.

You can give them access to other AWS services, on-premises networks, and even the internet. To learn more about how to architect Client VPN connectivity see this blog post. You can configure routing rules to decide what your remote users can connect to.
I’ve set up Client VPN to provide network access only to the target VPC but you can expand it to other resources. At that point, the group membership information can be used to authorize access to specific resources. Because Client VPN trusts the IdP, this is accepted as proof that the user is authenticated and the session can be established.

Client VPN software forwards the SAML assertion to the Client VPN endpoint. This is also called a SAML assertion and includes details about the user like their email and group membership. On successful authentication the IdP generates a signed SAML response. User authenticates to the IdP in their browser by providing their credentials and, if enabled, a second authentication factor. If that user hasn’t authenticated before, they are redirected to the IdP in their default browser. 
User attempts to create a VPN connection to the Client VPN endpoint using AWS Client VPN software. If you are setting up SAML integration for the first time, you must establish trust between the IdP and the service provider (AWS Client VPN, in this case). The flow diagram below shows what the SAML authentication process looks like for Client VPN.įigure 1: Client VPN SAML authentication flow Once successfully authenticated, they can connect to the EC2 instance. Users connecting to Client VPN are authenticated against my SAML IdP. I created a Client VPN endpoint and associated it with my VPC. My architecture includes a target Amazon VPC hosting a single EC2 instance. Remote users connecting to Client VPN can authenticate with the same credentials they are using for any other service already integrated with Okta. In this blog post, I show how to integrate AWS Client VPN with Okta, a popular identity provider. SAML-based federated authentication becomes a third authentication option for Client VPN - in addition to Active Directory and certificate-based mutual authentication, which are already supported. With the launch of Federated Authentication via SAML 2.0, Client VPN can now be configured a service provider in your existing IdP. The centralized identity store is known as identity provider (IdP) and applications that integrate with it are referred to as service providers (SPs).ĪWS Client VPN enables your remote users to securely connect to services on AWS and beyond. SAML 2.0 specification defines names for each of the components. This significantly improves their authentication experience and makes management of multiple applications simpler for the organization. With SAML, users can connect to multiple services with a single set of credentials. It is an open standard that allows organizations to have a centralized store to manage their identities. It is difficult to manage for IT departments and doesn’t provide a good experience for users.Ī common way to solve this challenge is to use Security Assertion Markup Language (SAML) 2.0. Having a separate set of credentials for each application is not an efficient approach. 
Authenticating users to applications and services on the web and at scale can be challenging.
