Edit the ACS url to be (port 35001) and click SAVE. To do this, we use the Network tab of Developer Tools in a browser to get the payload.Ĭlick on Service Provider Details of the SAML app in Google Admin Console and switch on Network recording in the browser developer tools. Next, we need to use a browser (Firefox is used in the example) to get a valid POST request for an amendment to the SAML app and configure it to use local http instead of https. In the Attributes screen, set up the following three mappings, then click Finish. Check the Signed response checkbox, and click CONTINUE. We will fix this using a curl command soon), and urn:amazon:webservices:clientvpn for Entity ID. In the Service Provider Details screen, enter for ACS URL (we will eventually change this to, which is required by AWS, but Google only allows the URL to start with https. In the Web and mobile apps page, click on the Add app dropdown, and select Add custom SAML app.Įnter a suitable name for the app, and click CONTINUE twice to get to the Service Provider Details screen (DO NOT download the metadata as it will not work with AWS without customisation). Log in to your Google Admin Console, select Apps -> Overview, then click on the Web and mobile apps tile. Solution Setup Phase one: configure Google Workspace (G Suite) to act as an identity provider for AWSĪ SAML application needs to be created via the Google Admin Console and provisioned to users so that permissions are granted to authenticate with AWS Client VPN. There is no need to remember to revoke access or remove keys from a bastion host. By leveraging Google Workspace to provide authentication for AWS Client VPN, you can ensure that only people with access to your Google organisation can access your AWS VPN.Īs an added benefit, access to AWS Client VPN will be automatically granted/revoked as engineers are onboarded and offboarded in your Google Workspace organisation. Many start-ups and smaller companies (as well as some large ones!) use Google Workspace (formerly G Suite) as their identity provider. Why use Google Workspace for authentication? AWS Client VPN provides engineers with an endpoint to connect to from their remote machines, and injects a network interface into your private subnet for secure connection to your database (or any other resources in the subnet). End-users connect to the service via an Application Load Balancer in a public subnet. AWS Client VPN is highly available, elastic and deeply integrates with existing AWS services.Ĭonsider a simple web application stack consisting of a web server hosted on a single EC2 instance and an RDS database instance, both inside a private subnet. In recent years, AWS introduced Client VPN - a fully managed service offering secure connections into your Virtual Private Cloud (VPC) from any client device. Additionally, both of these solutions often become their own security concerns being both difficult to provision, manage and make reliable. Alternatively a bastion host can be used, but this often requires additional tools to be installed and adds another layer of complexity. Historically, virtual private networks (VPNs) are a common solution, and there are many custom options that require considerable setup and management. Bots and hackers are constantly scanning the web for vulnerabilities and they pose a significant risk to your data, services and your entire AWS environment.Īs an engineer, you may have a need to connect your remote computer to the private subnet layer to run queries on a database or test that the services running in your secure network are behaving as expected. Direct connections from the internet to secure application network layers (private subnets) or resources such as databases should be restricted. To secure your Amazon Web Services (AWS) environment, it is vital that access to sensitive data is carefully controlled.
