Trusted CI Experiences in Cybersecurity and Service to Open Science.

This article describes experiences and lessons learned from the Trusted CI project, funded by the US National Science Foundation to serve the community as the NSF Cybersecurity Center of Excellence. Trusted CI is an effort to address cybersecurity for the open science community through a single organization that provides leadership, training, consulting, and knowledge to that community. The article describes the experiences and lessons learned of Trusted CI regarding both cybersecurity for open science and managing the process of providing centralized services to a broad and diverse community. Over the past seven years, Trusted CI has impacted over 250 NSF projects across all seven NSF science directorates, helping to secure our nation's scientific cyberinfrastructure.
