Adversaries may stage data collected from multiple systems in a central location or directory on one system prior to Exfiltration. Data may be kept in separate files or combined into one file through techniques such as Archive Collected Data. Interactive command shells may be used, and common functionality within cmd and bash may be used to copy data into a staging location.
In cloud environments, adversaries may stage data within a particular instance or virtual machine before exfiltration. An adversary may Create Cloud Instance and stage data in that instance.(Citation: Mandiant M-Trends 2020)
By staging data on one system prior to Exfiltration, adversaries can minimize the number of connections made to their C2 server and better evade detection.

Comments
This control requires both CSP and CSC to independently enforce formal approval processes for user access, implement dynamic and explicit authorization mechanisms. The guidance focuses on implementing technical measures to verify authorization and prevent unauthorized access and execution.
