CMMC CLARIFICATION (Ref CMMC – Appendix B)

You should ensure that the system creates and retains audit logs. The logs should contain enough information to identify and investigate unlawful or unauthorized system activity. You select the events that require auditing. Also, you determine the information to record in the audit logs about those events.
