Source: OpenVPN: Enabling access to the corporate network with Cloud Identity credentials from Google Cloud
Editor’s note: Cloud Identity, Google Cloud’s identity as a service (IDaaS) platform, now offers secure LDAP functionality that enables authentication, authorization, and user/group lookups for LDAP-based apps and IT infrastructure. Today, we hear from OpenVPN, which has tested and integrated its OpenVPN Access Server with secure LDAP, enabling your employees and partners to use their Cloud Identity credentials to access applications through VPN. Read on to learn more.
As IT organizations adopt more cloud-based IaaS and SaaS apps, they need a way to let users access them securely, while still being able to use legacy LDAP-based apps and infrastructure. The new secure LDAP capabilities in Cloud Identity provides both legacy LDAP platforms and cloud-native applications with a single authentication source, for a simple, effective solution to this problem.
In fact, we here at OpenVPN have integrated our OpenVPN Access Server with Cloud Identity, allowing your remote users to connect to your corporate network and apps over VPN with their Cloud Identity (or G Suite) credentials. This helps keep your company secure, and ensures your entire team is following the protocol.
This illustration demonstrates how Cloud Identity makes security accessible and efficient for any level of enterprise. The top-half of the illustration shows the deployment of OpenVPN Access Server in various cloud IaaS providers. As you can see, all instances of Access Server use Cloud Identity for authentication and authorization. The Access Servers are configured with a group called ‘IT Admin,’ which allows SSH access to all application servers on all the private networks. This allows any employee identity present in Cloud Identity that is a member of ‘IT Admin’ group to access any of the private networks via VPN and use SSH.
Then, as you can see in the lower half of the illustration, remote employees use VPN to connect to your corporate network and apps with their Cloud Identity credentials.
Using Cloud Identity for authentication
OpenVPN Access Server v2.6.1 and later supports secure LDAP and has been tested to work with Cloud Identity. You can find specific configuration instructions on our website.
Using Cloud Identity groups for network access control
As shown in the illustration below, Access Server’s administrative controls make it easy to configure groups. Administrators can configure access controls for these groups with fine granularity down to an individual IP address and port number.
You can configure groups in Access Server that correspond to those stored in Cloud Identity and enforce access controls for the user based on that user’s group membership. You can do this kind of mapping by using a script on Access Server. Instructions to set up the script are available on our website. In addition, our support staff is also ready to help you.
With OpenVPN Access Server, you can protect your cloud applications, connect your premise to the cloud, and provide simple and secure access for your remote employees in a way that scales with the tools you’re already using. Best of all, OpenVPN Access Server is available on GCP Marketplace. Try it out today!
