CA Strong Authentication Windows Installation Guide › Introduction › System Architecture › Application Tier

Application Tier

This layer constitutes CA Strong Authentication Server, your application that uses CA Strong Authentication SDKs, and the application servers where the Administrative UI and the User Data Service (UDS) reside.

Note: All components in this layer can be installed on one system or can be distributed across multiple systems.

• CA Strong Authentication Server

  Server component that processes issuance and authentication requests from your application through CA Strong AuthenticationSDKs.

• CA Advanced Authentication

  Web-based console for configuring server instances, communication mode between CA Strong Authentication components, authentication policies, credential profiles, managing credentials, and for managing organizations, administrators, and users.

• User Data Service

  The abstraction layer that provides access to user- and organization-related data from different types of user repositories, such as Relational Database Management Systems (RDBMSs) and directory servers (LDAPs).

• Authentication API

  Java APIs invoked by your application to forward authentication requests to CA Strong AuthenticationServer.

• Credential Management API

  Java APIs invoked by your application to forward issuance requests to CA Strong AuthenticationServer to create and manage user credentials in CA Strong Authentication.

• User Management API

  Web Services client invoked by your application to forward issuance requests to UDS to create and manage users in CA Strong Authentication.

• Sample Application

  Sample Application demonstrates the usage of CA Strong Authentication Java APIs and how your application integrates with CA Strong Authentication. It also verifies if CA Strong Authenticationwas installed successfully, and performs issuance and authentication operations.
