Info

►Application Security determines application specific requirements. In somecases, these values may override global security settings, but in most casesthey complement them. Application security includes such elements as: amethod for authenticating the users, a mechanism for authorizing the usersinto application specific resources, roles-based access control to theseresources, roles to user/user groups mapping, and so on. Application securityis administered during assembly phase using the Application Assembly Tool(AAT) and during the deployment phase using the WebSpherE AdministrativeConsole and the wsadmin client program.The diagram below presents a general overview of building blocks of a singleapplication server and how they interact in a Java client and Web browsercommunication. For a more detailed description of the security communicationflow, please refer to “Other security components” on page 226.NodeNodeAgentWebbrowserclientHTTP serverWebSphereplug-inApplication ServerWeb containerEmbeddedHTTP serverWebServicesengineConfigrepository(file)AdminUIClient containerJavaclientEJB containerAdminapplicationCustomerapplication (ear)Admin serviceApplicationDatabaseJ2C containerScriptingclientName Server (JNDI)Security serverEmbedded JMS ServerFigure 9-5 Single Application Server building blocksThis section presents a general overview of security components of theWebSphere Application Server and how they are used to create a flexiblepluggable architecture.222 IBM WebSphere V5.0 Security Handbook
9.2.1 Extensible security architecture modelThe diagram below presents general view of the logical layered securityarchitecture model of WebSphere Application Server V5.0.The flexibility of that architecture model lies in pluggable modules that can beconfigured according to the requirements and existing IT resources.The interface layer allows you to connect different modules responsible forauthentication, authorization and user registry.The pluggable user registry allows you to configure different databases to storeuser IDs and passwords that are used for authentication. Detailed information onhow to interface to custom registry using the UserRegistry interface can be foundin Chapter 8, “Programmatic security” on page 179.NT/UnixuserregistryLDAPuserregistryCustomuserregistrySWAM LTPA JAASTivoliAccessManagerz/OSothervendor'sORBPluggable UserRegistryPluggableAuthenticationWebSphere Application ServerPluggableAuthorizationIBMCSIv2CSIv2IBMFigure 9-6 WebSphere V5 extensible security architectureThe pluggable authentication module allows you to choose whether WebSpherewill authenticate the user or will accept the credentials from externalauthentication mechanisms. For information on how to configure WebSphere touse credentials from IBM Tivoli Access Manager, please refer to Chapter 12,“Tivoli Access Manager” on page 369. In the future, this authentication interfacewill be extended to include other external authentication systems.Pluggable authorization interfaces will allow the use of different authorizationmechanisms for WebSphere applications. In the current version, JAAS issupported and Tivoli Access Manager is an external authorization system.Chapter 9. WebSphere Application Server security 223
