The clouds can be a scary place. All these machines that simply aren't yours. So how can you make sure you continuously keep your cloud infrastructure secure? OWASP Cumulus is the easy way to bring security into the cloud and your DevOps teams. Play it at copi.owasp.org!
As a variant of the card game Elevation of Privilege it follows the idea of threat modeling a system via gamification. This lightweight and low-barrier approach helps you to find threats in your DevOps or cloud project and teaches the developers a security oriented mindset.
Threat Modeling
The idea of threat modeling via serious games goes back to the card game Elevation of Privilege by Adam Shostack. The basic idea is to bring the developers to the table and get them to start discussing the security of their system. For this, a card game serves as a guide through a catalogue of threats. It is designed to be a low-barrier and naturally embeddable approach within agile software development processes.
While we at OWASP Cornucopia have been focusing on creating games focused on web- and mobile application security, we have felt that the specific needs of the DevOps team working in cloud environments have been missing. OWASP Cumulus seeks to fill this gap and provides a custom card deck with threats for cloud systems.
