Abstract

A workflow system automates processes that occur during the daily operation of an organisation. The description of such a process inherently includes information about who needs to perform each step. It also includes information about when this subject has to perform that step. This information can be used to enhance security in the system. In particular the when information can be used to dynamically adapt security according to the current state of the workflow process.

This paper considers the issues involved in using workflow to enhance security. We propose an architecture that uses the information contained in workflow scripts to dynamically modify security specifications. This information can be used to increase confidentiality, integrity and availability.

The paper is primarily interested in secure interorganisational workflow. The proposed system is based on a secure federated database shared amongst the participating organisations.
