Forensics Web Services (FWS)

Web services are currently a preferred way to architect and provide complex services. This complexity arises due to the composition of new services and dynamically invoking existing services. These compositions create service inter-dependencies that can be misused for monetary or other gains. When a misuse is reported, investigators have to navigate through a collection of logs to recreate the attack. In order to facilitate that task, we propose creating forensics web services (FWS) that would securely maintain transactional records between other web services. These secure records can be re-linked to reproduce the transactional history by an independent agency. In this report we show the necessary components of a forensic framework for web services and its success through a case study.
