CCI-000880 says: "The operating system must audit non-local maintenance and diagnostic sessions." and "Non-local maintenance and diagnostic activities are those activities conducted by individuals communicating through a network, either an external network (e.g., the Internet) or an internal network, in order to conduct system diagnostics. For traceability of maintenance, logging events associated with a non-local administrative access or diagnostic session must be performed." What actions do we want to consider "maintenance and diagnostic" commands/tools?
