Assessment Center takes security very seriously.  The last long section of the Assessment Center User Manual (www.nihpromis.org) includes information about security including details about the system architecture, SSL encryption, and server security. Additionally, within a study Assessment Center utilizes role-based permissions.  Only team members are able to get access to a given study.  Their access is limited based on their assigned role.  Only individuals with the appropriate role are able to access participants’ data.
