Social Sign-On


Support for Social Sign-On Overview

Simple new user

registration increases

sign up rate.

Use consumer identity

for initial customer acquisition and low risk transactions.

Collecting identity and device attributes allows for personalized marketing.

Seamless sign-on encourages registration and enables targeted marketing.

Sign on with stronger credentials when needed for high value transactions.


Support for Social Sign-On Use Case

User initiates a sign-on request using his social

sign-on account (OAuth request).

User is redirected to the selected remote authorization server and logs in.

The OAuth flow is completed via the backchannel.

If configured, user information is retrieved from the configured user

information URL via the backchannel.

Once authorized, the browser is redirected to the configured target page.

If authorized but not found in the user store, JIT provisioning process can

be launched (first time access/create account).


Support for Social Sign-On Requirements

Pre-configured OAuth authorization server support for:

– Twitter (OAuth 1.0a)

– Facebook, Google, LinkedIn, Microsoft (OAuth 2.0)

– Many other OAuth Identity Providers

Client registration with the remote authorization server is required before

creating partnership


Create the local OAuth client entity.

Create or modify the remote entity of an authorization server.

Create a partnership to configure single sign-on.

Migrate an OAuth authentication scheme to OAuth Partnership.

Use both the OAuth authentication scheme and an OAuth partnership

simultaneously.

– Add the new redirect URL to the existing OAuth authentication scheme redirect URL.

Use an OAuth partnership instead of the OAuth authentication scheme.

– Update the existing redirect URL at the OAuth authorization server to the appropriate partnership redirect URL.

Credential Handling ServiceOverview

Simplified configuration for letting the end user choose the authentication

provider

Supports identity providers using federation partnerships

Is deployed on the CA Access Gateway


Credential Handling Service Use Case

Make several federated partnerships available for login. The credential

handling service shows the partnerships in the group.

– An unauthenticated user requests a resource protected by CA SSO and is presented with the choice of identity providers

– The user selects an identity provider to authenticate with

– The selected partnership is invoked and the user is redirected to the identity provider for login and back to CA SSO

– When the user is identified by CA SSO the user is redirected back to the original target page

– When the user is not found by CA SSO provisioning can occur


Credential Handling ServiceRequirements

CA Access Gateway

Partnership between CA SSO and the enterprise (CA SSO) where protected

resources exist

Partnership between CA SSO and identity providers


Configure partnerships to identity providers.

Create an authentication method group.

Configure a partnership to the enterprise.

Credential Handling ServiceConfiguration

Optionally customize the credential selector page.14


Credential Handling ServiceLogin Flow Detail (Registered User)

An unauthenticated user invokes a partnership with CHS enabled.

The user selects an identity provider and signs-on. The identity provider generates

an access token and redirects the user to the federation system (relying party).

The federation system (relying party) verifies the access token, disambiguates the

user, and generates a session.

The federation system (asserting party) generates an assertion and redirects the

user to the enterprise (relying party).

The enterprise (relying party) verifies the assertion and gives the user access to

the federated resource.


Credential Handling ServiceCreate an authentication method group.


Credential Handling ServiceConfigure a partnership to the enterprise.

Partnership based on one of these authentication protocols:– SAML 1.1 – SAML 2.0 – WS-Federation

SSO – Authentication mode = Credential Selector– Define the base URL– Select the previously created Authentication Method Group

Target Application– SAML1.1: Target– SAML 2.0 and WS-Federation: Relay State Overrides Target


Credential Handling ServiceCustomize the header or footer.

<install_path>\CA\secure-proxy\Tomcat\webapps\chs\jsps

Make a copy of the header.jsp file and name the new file header-

custom.jsp.

Make a copy of the footer.jsp file and name the new file footer-

custom.jsp.

Customize the new files as needed.

Restart CA Access Gateway.

Open Format CookieAgentless-SSO


Open Format Cookie = “agentless” SSOOverview

Standards-based cookie directly read by applications

No agent or proxy installed between user and web server

– Lower cost method for accomplishing basic SSO

– Web applications decrypt (optional) and consume the standard cookie

– Adds flexible option to a customer’s CA SSO architecture

For applications that have lower security requirements

– No centralized auditing, CA SSO authorization or centralized session control

Web Agent in the CA SSO architecture

used for protection and cookie generation


Open Format Cookie Use Case

When not possible/not convenient to deploy a Web Agent

Less stringent security and session control over applications

Generated in response to a successful authentication or authorization event


Open Format Cookie Configuration

Web ServicesSOAP and REST APIs


SOAP and REST APIsOverview

Web service interfaces for authentication and authorization

Deployed via CA Access Gateway

Supports SOAP (wsdl) and REST (wadl) architectures

http(s)://server:port/authazws/auth?wsdl

http(s)://server:port/authazws/AuthRestService/application.wadl

Lower cost method for integrating CA SSO services

Adds flexible option to a customer’s CA SSO architecture


SOAP and REST APIsOverview

Authn/Authz web services provide following functionality:

– login – Authenticates and returns session token (and optional identity token)

– blogin – (Boolean login) authenticates and verifies whether login is successful and does not return session token

– logout – Logs out the user or group of users

– authorize - Returns an authorization status message and a refreshed session token


SOAP and REST APIs Use Case User accesses mobile gateway via smart

phone.

Mobile Gateway calls web service interface to authenticate user.

Web service validates with CA SSO Policy Server.

CA SSO validates/authorizes request.

Web service provides validation/authorization status back to mobile gateway via session token.

Mobile gateway requests content from web server.

Content is returned to user.
