We're trying to configure customer access to JIRA, and don't want to display any internal project data. We've got all internal projects secured with a specific internal Permissions Scheme. After setting up the customer accounts, I logged in with one to see what they see. All projects are secured properly; however, I can search for and display the System Dashboard. That wouldn't be so bad, but on the system dashboard is the Activity Stream, showing issues from all projects. Is there a way to restrict the view of the Activity Stream, say, by jira group? Or is there another slick way that I can restict the view our external customers have of the activity stream?
