Abstract

Custom SME applications for collaboration and workflow have become affordable when implemented as Web applications employing Agile methodologies. Security engineering is still difficult with Agile development, though: heavy-weight processes put the improvements of Agile development at risk. We propose Agile security engineering and increased end-user involvement to improve Agile development with respect to authorization policy development. To support the authorization policy development, we introduce a simple and readable authorization rules language implemented in a Ruby on Rails authorization plugin that is employed in a real-world SME collaboration and workflow application. Also, we report on early findings of the language’s use in authorization policy development with domain experts.
