Description
SMF data collection is the basic unit of tracking of all system functions and actions. Included in this tracking data are the audit trails from each of the ACPs. If the control options for the recording of this tracking are not properly maintained, then accountability cannot be monitored, and its use in the execution of a contingency plan could be compromised. Satisfies: SRG-OS-000032-GPOS-00013, SRG-OS-000392-GPOS-00172
