Before we begin to look into the specifics of WebSphere Application Server 8 administration, it is important to understand what the product is, why it is often the product of choice to provide a base for an enterprise JEE SOA Service Oriented Architecture along with support for the many Java-based standards, and how an organization can benefit from using WAS.
We also need to cover some specific WAS terminology and concepts used throughout the tutorial. Over the last 10 years, since version 1. Every new version is required to provide improved efficiency and continued compliancy with standards, allowing customers who invest in WAS to make use of the new Java capabilities of each new JEE release.
When choosing an application server platform on which to run applications and services, architects and developers need to know that WAS will support new JEE features and improved coding practices. The following table shows a simple comparison of current and previous WAS versions and its compliancy to JEE specifications:. JEE is an ever-changing world, and as soon as a new application server is released by IBM, new standards and approaches become available, or they become the preferred method of choice by the JEE community.
Organizations who have invested in JEE technology require an application server platform that allows them to extend their existing legacy systems, and provide services-based frameworks on which their enterprise applications and systems can be based. So there is a continuing need for IBM to facilitate all the facets of the new JEE enterprise features, namely JMS, Web Services, Web Applications, and Enterprise JavaBeans, ensuring their product continues to innovate and provide the ability for their customers to extend their own core systems.
The WAS product is continually being updated and improved to bring in new technologies as they are released or accepted by the community as a whole. WAS can be considered the base of your enterprise JEE application service provisioning toolbox and can be extended with custom business solutions as required. Developers and architects want to ensure that their application designs use the latest JEE standards and programming models. IBM assesses every new specification and determines the features they will implement.

There have been many internal product improvements for efficiency in both resource management and administration time-saving. The following table gives an overview of new enhancements to WAS realized in version WAS continues to provide ease of integration with MQ.
Security domains have been improved to offer more secure protection for services provided by WAS. The Organization for the Advancement of Structured Information Standards OASIS is a global consortium that drives the development, convergence, and adoption of e-business and web service standards. Auditable security events are security events that have audit instrumentation added to the security run time code to enable them to be recorded to logs for review. Enhanced security configuration reporting, including session security and Web attributes. Java Authentication SPI for Containers JSR support, which allows third-party authentications for requests or responses destined for web applications.
Configure federated repositories at the domain level in a multiple security domain environments. This should give you an insight and understanding into what WebSphere 8 has to offer in the way of JEE 6 support for these containers. The JEE specification outlines four types of container, as shown in the following diagram.

These containers form the guidelines of the services, which are to be provided by a JEE application server as implemented by a software vendor like IBM:. IBM assesses every new specification, and determines the features they will implement. There have been many internal product improvements for efficiency in both resource management and administration time saving.
A JEE application will use one or more of the previous four components, that is an application can simply be a web application running in the Web Container alone, or a JEE application can be more complex and contain both Web components and EJB components, and so more than one container can be used in serving an application. The Applet container manages Java applets. An Applet is a Java program that can be embedded into a web page. The Applet container manages the execution of the applet, and contains the web browser.
The Web container , also known as a Servlet container , provides web-related services. In a nutshell, this is the component of a web-server which serves web content, web-services, facilitates web-security, application deployment, and other key services. Enterprise JavaBeans are used in distributed applications, and facilitate transaction services and appropriate low-level implementations of transaction management and coordination, as required by key business processes. They are essentially the business components of an application. The EJB container also manages database connections and pooling, threads, and sockets on behalf of enterprise beans, as well as state and session management.
JEE applications are deployed to an Application Server. A common type of business application is a web application. Applications need not only comprise of web components. In a more complex enterprise-based application, business objects are created to provide a layer of abstraction between a web application and the underlying data. A virtual host is a configuration element that is required for the web container to receive HTTP requests.
As in most web server technologies, a single machine may be required to host multiple applications and appear to the outside world as multiple machines. Resources that are associated with a particular virtual host are designed not to share data with resources belonging to another virtual host, even if the virtual hosts share the same physical machine. Each virtual host is given a logical name and assigned one or more DNS aliases by which it is known.
By default, two virtual host aliases are created during installation. All web applications must be mapped to a virtual host, otherwise web browser clients cannot access the application that is being served by the web container.
Using OAuth: Enabling the OAuth service provider in WebSphere Application Server
WebSphere uses Java environment variables to control settings and properties related to the server environment. Resource definitions are a fundamental part of J2EE administration. Application logic can vary depending on individual business requirements, and there are several resource types that can be used by an application. The following table shows a list of some of the most commonly used resource types:. Naming operations, such as lookups and binds, are performed on contexts. All naming operations begin with obtaining an initial context.
You can view the initial context as a starting point in the namespace. An access manager makes authorization decisions based on the security policy derived from the deployment descriptor. An authenticated user principal can access the requested EJB method if it has one of the required security roles. When RunAs identity is specified, it applies to all bean methods. FIPS are developed when there are compelling federal government requirements for standards, such as for security and interoperability, but acceptable industry standards or solutions do not exist.
It also addresses enterprise end-to-end security requirements on: WebSphere Application Server security is a layered architecture built on an operating system platform, a Java virtual machine JVM , and Java 2 security. This security model employs a rich set of security technology including the: Java 2 security model, which provides policy-based, fine-grained, and permission-based access control to system resources. Both protocols are supported by prior WebSphere Application Server releases.
Exactly one user registry implementation can be configured to be the active user registry of WebSphere Application Server security domain. WebSphere Application Server provides the following user registry implementations: It also provides file-based and Java database connectivity JDBC -based user registry reference implementations. It supports a flexible combination of authentication mechanisms and user registries. SWAM is simple to configure and is useful for a single application server environment. It is possible to use SWAM in a distributed environment if identity assertion is enabled.
The identity assertion feature is available only on the CSIv2 security protocol.

More specifically, a reverse proxy server can act as a front-end authentication server while the WebSphere Application Server applies its own authorization policy onto the resulting credentials that are passed by the proxy server. The reverse proxy server applies its authentication policies to every web request that is dispatched to WebSphere Application Server. The products that implement trust association interceptors TAI include: Security attribute propagation enables WebSphere Application Server to transport security attributes from one server to another in your configuration.
Security attributes include authenticated subject contents and security context information. WebSphere Application Server can obtain these security attributes from either: An enterprise user registry that queries static attributes A custom login module that can query static or dynamic attributes Security attribute propagation provides propagation services using Java serialization for any objects that are contained in the subject.
For more information on using security attribute propagation, refer to Security attribute propagation. When a security policy is specified for a web resource and IBM WebSphere Application Server security is enforced, the web container performs access control when the resource is requested by a web client. The web container challenges the web client for authentication data if none is present according to the specified authentication method, ensures that the data constraints are met, and determines whether the authenticated user has the required security role.
WebSphere Application Server supports the following login methods:
