Overview of Okta with OAuth, step-up authentication, and RADIUS MFA
You can create a Zero Trust Identity Aware Proxy configuration using Okta and OAuth, with RADIUS MFA. For this scenario, the Zero Trust proxies are Access Policy Managers configured in Client + Resource Server configurations. APM is configured as the Authentication Server. RADIUS is used for multifactor authentication in a branch that requires more authentication (for example, an /admin URL). In this scenario, the authentication server uses the Zero Trust Step-Up Authentication feature to provide seamless access across different apps.
To create a configuration for Seamless Auth with Okta, OAuth, and RADIUS MFA, you must complete the following steps.
- Create the Okta configuration
- Create an Okta OAuth provider
- Configure an OAuth client and resource server on APM
- Create an allow-all access policy and a per-request policy
- Create configuration objects in the per-request policy
- Assign the access policy and per-request policy to a virtual server
