We've had our Production Jira installation in place for several years. Previously, it was managed only by the various development groups. Over time, it's grown and we're now seeing security issues with users having more permissions than they need. Now that the system is under IT management, we'd like to address this concern and are looking for best practice documentation on how to properly set up groups/permission schemes/etc...
Do you have such documentation available? If so, can you provide links? Thanks much
