Controlled Information is a general term that describes the information that needs to be secured and monitored; this can be physical information or electronic information. This would include information stored locally on portable media, a USB device, your phone, or in the cloud. The information could be government-controlled as Federal Contract Information (FCI) or Controlled Unclassified Information (CUI).
In addition, it should include company-controlled information (CCI) as financial data, customer information, personnel information, intellectual property, etc.
