Identity management (IdM) solutions in web services environments are often compared on the levels of performance and security they provide. Selecting the appropriate IdM solution for a given system or application often requires making tradeoffs between security and performance, while also considering the system's contextual and environmental requirements and constraints. This paper presents the results of a series of experiments targeted at analyzing the performance impact of adding WS-Security, a common security standard used in IdM frameworks, to SOAP-based web services. The goal of this work is to establish a baseline of performance data that can be used to explore performance/security tradeoffs in environments with complex attributes, such as resource or bandwidth limitations.
