OpenStack Summit, Fall 2012. As OpenStack continues to mature, it is increasingly important for the community to be proactive in improving security. The OpenStack Security Group (OSSG) is a new effort led by Nebula and HP to bring together security professionals who can work to address this need. Our goal is to create a group that complements the Vulnerability Management Team by working to improve the security in each project's software architecture, contributing software to address security relevant blueprints and bugs, and providing cross-project security assessments. This talk will introduce the OSSG and describe some of our early success stories, while starting a conversation about the best path forward for OpenStack security. https://www.openstack.org/summit/san-diego-2012/openstack-summit-sessions/presentation/building-an-openstack-security-group
