Oracle Web Services Manager

Feb 2007


Introduction

Oracle Web Services Manager (WSM) is a comprehensive solution for securing and managing service-oriented architectures (SOA). It allows IT managers to centrally define policies that govern web services operations such as access control (authentication, authorization), logging, and content validation, and then attach these policies to one or multiple web services, with no modification to existing web services required. In addition, Oracle WSM collects runtime data to monitor access control, message integrity, message confidentiality, quality of service (defined in service-level agreements --SLAs) and displays that information in a graphical charts. Oracle WSM brings enterprises better control and visibility over their SOA deployments.

Key features of Oracle WSM include:

  • Policy Manager

  • Enforcement

  • Monitoring Dashboard

Policy Manager

Policy Manager is a graphical tool for building new security and operations policies, storing policies and managing distribution and updates to runtime policy enforcement points (gateways and agents). Policy Manager allows administrators to configure operational rules and propogate them to the appropriate enforcement components across an application deployment of any scale and complexity.

Enforcement

To ensure maximum deployment flexibility, Oracle WSM provides two kinds of policy enforcement components: Gateways and Agents. Gateways are deployed in front of a group of applications or services. Gateways can intercept inbound requests to these applications in order to enforce policy steps defined in the Policy Manager, adding application security and other operation rules to applications that are already deployed. Agents provide "last-mile" security by running directly into an application or service.

Monitoring Dashboard

Monitoring Dashboard collects data from Gateways and Agents as they execute policies and displays results in a graphical format. This allows administrators to set quality-of-service levels for each application and display alerts when the application exceeds established thresholds. Monitoring Dashboard provides IT operations staff with real-time visibility into the health, performance, security and utilization of crucial web services. By harnessing the realtime data collection capabilities of the enforcement components, Monitoring Dashboard enables administrators to analyze discrepancies between expected and actual performance and to monitor compliance with IT operational best practices.

Supported platforms and technologies

Oracle WSM works with multiple Web services platforms and providers including BEA Systems, IBM, JBoss, CA/Netegrity, etc. For example, sites using IBM's WebSphere or BEA's Weblogic Server can install Oracle WSM Agents to act as SOAP interceptors that enforce Web service policies.

Oracle WSM also supports Forum Systems' XWall product through a pre-built integration. Oracle customers thus benefit from centralized monitoring of both perimeter and internal operations from a single console. XWall sends its monitoring events to the Monitoring Dashboard, so that both firewall and management operations are viewable. This integration also provides links between the Oracle WSM's Policy Manager and XWall, so that customers can build and manage both firewall and Web service policies with a single tool.

Availability
Oracle WSM ships both as a standalone product running on Oracle Application Server 10g Release 3 (10.1.3) and as part of the Oracle SOA Suite (10.1.3).
