IBM Websphere Application Server Version 8

IBM® WebSphere® Application Server (WAS) is IBM's leading open standards-based application foundation.

It is based on open standards such as Java™ Platform, Enterprise Edition (Java EE), XML, and Web services and it provides a service-oriented architecture (SOA) platform to host, for example, applications that conform to Java EE.

The security model for WAS uses services offered by the underlying operating system and the Java EE security model.
