What is it?

Security framework for Java EE● Apache License V2● First class support for CDI● Secures your beans, bean methods, view layer,

RESTful endpoints, servlets and more● Simple API for managing Users, Groups and Roles● Authenticate any way you want● Federation (SAML, WS-Trust, OpenID)

Identity Management

Manage users, groups, roles and more● Built in support for storing your identities in:

● File system● A relational database (using JPA)● LDAP

● Well defined SPI for creating custom identity stores● Powerful query API for querying identities● All operations done through IdentityManager,

which can be simply @Injected into your beans

BYO Identity Model

● We provide you with optional User, Group, Role classes

● We also provide a few default relationships – group membership, group role and application role

● But custom relationships (between two or more participating identities) are also easy to define

● Provides the flexibility you need to meet the requirements of your business or project

Authentication

Authentication is initiated with Identity.login()● Identity bean is a session-scoped bean that tracks

the current user

Authenticator can be configured per application or per request

● Supports multiple authentication methods in a single application (e.g. Username/password and OpenID)

● We provide some default (optional) support for some credential types

RESTful Authentication Endpoint

org.jboss.jdf.example.ticketmonster.security.rest.LoginService

● Username/password passed in via the credential param● Identity.login() invoked

● If authentication successful, the User object is read from the Identity bean and passed back in the REST response

● We haven't configured an Authenticator for this application, so by default Identity Management is used to authenticate

11

Where are our users defined?

org.jboss.jdf.example.ticketmonster.security.IdentityManagementInitializer● @Startup bean is instantiated during app startup

● IdentityManager is @Injected

● initialize() is a @PostConstruct method● Is executed automatically● Creates the users, roles and default passwords for our

application● Sensible IDM configuration defaults make this possible

12

Securing application methods

org.jboss.jdf.example.ticketmonster.rest.BookingService● We want to restrict the createBooking() method to

only logged-in users● @UserLoggedIn is a Security Binding Type, an

annotation used to restrict access to beans and bean methods

● This feature is provided by Apache DeltaSpike● A Security Binding Type requires an Authorizer method,

annotated with @Secures in addition to the binding annotation

13

Implementing the Authorizer method

org.jboss.jdf.example.ticketmonster.security.AuthorizationManager● The isUserLoggedIn() method controls access to

methods annotated with @UserLoggedIn● Is annotated with both @Secures and @UserLoggedIn● Parameters of an authorizer method are treated as

injection points● Must return a boolean to indicate whether the

authorization was successful – a result of true means the restricted method may be invoked by the current user

14

Servlet security

org.jboss.jdf.example.ticketmonster.security.RoleBasedAuthorizationFilter● Standard servlet filter, active for all requests

● Delegates authorization check to AuthorizationManager.isAllowed()

● Only allows requests to /admin/* URLs if user has the Administrator role

● IdentityManager.hasRole() method used to check if the current user has the required role

15

View layer security

We can also tailor the user experience based on the current user's privileges

● JSF <ui:fragment> control can be used to show or hide parts of the page based on roles

● Can access the Identity bean directly via EL, e.g. #{identity.loggedIn}

● Can also use application-specific checks, e.g. AuthorizationManager.isAdmin()

User Registration

IDM makes it easy to implement user self-registration● org.jboss.jdf.example.ticketmonster.security.rest.RegistrationService

● The register() method receives a user registration request

● The performRegistration() method creates a new User, assigns them the User role, and adds them to the Users group.

● The registering user is even automatically logged in by the performSilentAuthentication() method

● An alternative would be to send a confirmation e-mail

Other IDM Features

Built-in authentication support for● Form-based, BASIC, DIGEST, X509 Certificate,

Username/PasswordPassword encoding● Defaults to a salted hash, or BYOMix and match identity stores● Store your users in LDAP, roles and groups in DB
