CMMC Practice Requirement:

Ensure that the actions of individual system users can be uniquely traced to those users so they can be held accountable for their actions.

CMMC Requirement Explanation:

In the event of a security incident you will need to review system logs to trace events back to a user. If your systems are not configured to capture the appropriate logs you will not be able to identify which account committed the security incident.

Example CMMC Implementation:

Your systems need to capture logs that can aid in tracing actions back to a user. Your logs should capture user IDs, source and destination IP addresses, and time stamps.


- Scenario 1:

Alice, a system administrator wants to determine which users are connecting to her network via the VPN. To accomplish this she configures her VPN to capture the following information: Username, computer/machine name, time stamp, source and destination IP address. Using the above logs she can trace VPN connections back to a specific individual.
