Abstract: Science gateways are user-facing cyberinfrastructure that provide researchers and educators with Web-based access to scientific software, computing, and data resources. Managing user identities, accounts, and permissions are essential tasks for science gateways, and gateways likewise must manage secure connections between their middleware and remote resources. The Custos project is an effort to build open source software that can be operated as a multi-tenanted service that provides reliable implementations of common science gateway cybersecurity needs, including federated authentication, identity management, group and authorization management, and resource credential management. Custos aims further to provide integrated solutions through these capabilities, delivering end-to-end support for several science gateway usage scenarios. This paper examines four deployment scenarios using Custos and associated extensions beyond previously described work.
