Research output: Contribution to journalArticlepeer-review


Science gateways have emerged as a concept for allowing large numbers of users in communities to easily access high-performance computing resources which previously required a steep learning curve to utilize. In order to reduce the complexity of managing access for these communities, which can often be large and dynamic, the concept of community accounts is being considered. This paper proposes a security model for community accounts, organized by the four As of security: Authentication, Authorization, Auditing and Accounting.
