How Verified Access works - AWS Verified Access

How Verified Access works

AWS Verified Access evaluates each application request from your users and allows access based on:

  • Trust data sent by your chosen trust provider (from AWS or a third party).

  • Access policies that you create in Verified Access.

When a user tries to access an application, Verified Access gets their data from the trust provider and evaluates it against the policies that you set for the application. Verified Access grants access to the requested application only if the user meets your specified security requirements. All application requests are denied by default, until a policy is defined.

In addition, Verified Access logs every access attempt, to help you respond quickly to security incidents and audit requests.

Key components of Verified Access

The following diagram provides a high-level overview of Verified Access. Users send requests to access an application. Verified Access evaluates the request against the access policy for the group and any application-specific endpoint policies. If access is allowed, the request is sent to the application through the endpoint.

    Using Verified Access to authenticate an application request from a user.
  • Verified Access instances – An instance evaluates application requests and grants access only when your security requirements are met.

  • Verified Access endpoints – Each endpoint represents an application. You can create a load balancer endpoint or a network interface endpoint.

  • Verified Access group – A collection of Verified Access endpoints. We recommend that you group the endpoints for applications with similar security requirements to simplify policy administration. For example, you can group the endpoints for all your sales applications together.

  • Access policies – A set of user-defined rules that determine whether to allow or deny access to an application. You can specify a combination of factors, including user identity and device security state. You create a group access policy for each Verified Access group, which is inherited by all endpoints in the group. You can optionally create application-specific policies and attach them to specific endpoints.

  • Trust providers – A service that manages user identities or device security state. Verified Access works with both AWS and third-party trust providers. You must attach at least one trust provider to each Verified Access instance. You can attach a single identity trust provider and multiple device trust providers to each Verified Access instance.

  • Trust data – The security-related data for users or devices that your trust provider sends to Verified Access. Also referred to as user claims or trust context. For example, the email address of a user or the operating system version of a device. Verified Access evaluates this data against your access policies when it receives each request to access an application.
